When a crushing project moves from simple size reduction to making better-shaped aggregate and manufactured sand, the crushing process starts to become more demanding. In this situation, I usually pay more attention to the final particle shape, the amount of stone powder, the feed size, the material being processed, and how easily the whole plant can be adjusted.

That is where the SP7150VE crawler vertical shaft impact crusher comes into the picture. The current Sunward specification identifies this machine as an electric skid VSI crushing plant. It is designed mainly for manufactured sand production, aggregate shaping and fine crushing, with a rated processing capacity of 125–300 t/h and a maximum crusher feed size of 45 mm.

From our side at Ganglong Heavy Industry Technology (Hefei) Co., Ltd., we treat a crushing plant as part of a complete production solution rather than simply selling a machine. Founded in 2013, Ganglong combines equipment-related services with international trade through Hefei Ganglong International Trade Co., Ltd. Our team works with customers across construction machinery, mining machinery, agricultural machinery and related attachments.

For international customers looking for a VSI crushing plant, our job is to understand the actual working condition first. What material are you crushing? What is the feed size? What final products do you need? How many tonnes per hour do you expect? Is the plant connected with a screening system? What kind of power supply is available? These questions matter much more than simply looking at a machine name.

In this page, I will walk through the SP7150VE from a practical point of view, including its working principle, technical configuration, advantages, applications, comparison with other crushing equipment, inspection and delivery process, and the questions customers usually ask before purchasing.

1. What Is the SP7150VE vertical shaft impact crusher?

A vertical shaft impact crusher, usually called a VSI crusher, works differently from a traditional Jaw Crusher or cone crusher. Instead of mainly squeezing material between two surfaces, a VSI crusher uses a high-speed rotor to throw material against other material or against impact surfaces inside the crushing chamber.

The basic idea is quite simple. Suitable feed material enters the crusher. The rotor accelerates the material at high speed. The material then collides inside the crushing chamber, breaks down further, and leaves the machine in a more controlled shape and size.

For aggregate producers, this difference can be important. When the goal is not only to reduce rock size but also to improve the shape of the finished particles, a VSI stage can be useful. It can help produce more cubical aggregate and manufactured sand with a controlled amount of fine material.

The SP7150VE is designed around this type of application. According to the current Sunward technical information, it uses a heavy-duty high-energy rotor, a dual-chamber design and configurable rotor options. The crushing chamber can be configured for either rock-on-rock or rock-on-metal operation depending on the material and product requirements.

That flexibility is one of the points I would discuss with a customer before recommending the machine. There is no single chamber configuration that makes sense for every rock type. Hard abrasive stone, softer material, manufactured sand production and aggregate shaping can place different demands on the crushing chamber and wear parts.

The machine has a maximum feed size of 45 mm and a processing capacity of 125–300 t/h. Its total working power is listed at 332.5 kW, while the machine has a total weight of approximately 46 tonnes. The official transport dimensions are approximately 19,110 × 3,896 × 3,800 mm.

For a buyer, I would treat these figures as the starting point rather than the final production guarantee. Actual output depends on material properties, feed grading, moisture, operating settings, wear condition and the complete crushing circuit.

2. How Does a Vertical Shaft Impact Crusher Work?

Understanding the working principle makes it much easier to understand why a VSI crusher is used for shaping and manufactured sand.

Material first enters the feed system and moves toward the crushing chamber. The high-energy rotor then accelerates the material. Once the material leaves the rotor, it enters the impact zone where crushing takes place through high-speed collision.

The SP7150VE uses a heavy-duty rotor and dual-chamber configuration. Sunward also lists two long and two short impact hammers as the standard arrangement. The combination is intended to provide strong crushing force and stable material movement through the crushing chamber.

There are two basic crushing approaches that can be selected according to the application. In a rock-on-rock configuration, material mainly impacts other material. In a rock-on-metal configuration, material impacts metal surfaces in the crushing chamber. The choice affects the crushing action, wear pattern and final product characteristics.

In real production, I would not choose between these two configurations simply because one sounds better. The correct choice depends on the feed material and the result the customer wants. For example, abrasive rock can place very different demands on wear components compared with less abrasive material.

Another useful feature is the integrated grading and dust-removal design. Manufactured sand production is not only about breaking stone into smaller pieces. The amount of fine material also matters. Too much powder can create problems in some applications, while too little fine material may make it difficult to meet a particular product specification.

The SP7150VE is designed to provide adjustable fineness modulus and controllable stone powder content. In simple terms, this gives the operator more room to adjust the production result instead of accepting whatever particle distribution comes out of the crusher.

The machine also includes a return screen measuring 3500 × 1500 mm. When used in a closed-circuit configuration, material that does not meet the required size can return to the crushing process. This allows the production line to keep working toward a more controlled final product.

For customers buying a complete crushing and screening solution, this part is worth discussing early. A VSI crusher should not be selected in isolation. The feeder, crusher, return screen, conveyors and downstream screening equipment all affect the actual production result.

3. Main Features I Look At in the SP7150VE

Heavy-Duty High-Energy Rotor

The rotor is one of the most important parts of a vertical shaft impact crusher. The SP7150VE uses a heavy-duty high-energy rotor designed to create the impact force needed for fine crushing and aggregate shaping.

For operators, this means the rotor is not just a rotating component. Its speed, balance, wear condition and configuration have a direct relationship with crushing performance. Regular inspection is therefore important, especially when the machine is working continuously with hard or abrasive rock.

Flexible Crushing Chamber

The SP7150VE allows different rotor configurations and supports rock-on-rock or rock-on-metal crushing chambers. This is useful because different projects have different targets.

If a customer is mainly producing manufactured sand, the required particle distribution may be different from a project producing shaped aggregate for road construction. The machine should therefore be configured around the final product rather than simply around the raw material.

Better Particle Shape

One of the main reasons to consider a vertical shaft impact crusher is particle shape. Traditional crushing stages can sometimes produce particles with less desirable shapes. A properly configured VSI stage can help improve the shape of the finished aggregate.

For concrete and asphalt applications, particle shape can be an important part of the overall material specification. A well-designed crushing circuit therefore often uses the VSI stage as a shaping or fine-crushing step after the larger primary and secondary crushing stages.

Controlled Fine Material

Manufactured sand production requires more control than simply making small particles. The balance between useful fine material and unwanted stone powder matters.

The SP7150VE integrates grading and dust-removal functions and is designed to provide adjustable fineness modulus and controllable stone powder content. This gives operators more control when they need to produce consistent sand or aggregate.

Return Screening System

The integrated return screen is another practical part of the system. The 3500 × 1500 mm screen is designed for product separation and return material control.

In a closed circuit, correctly sized material can move forward while oversize material returns for another crushing pass. This approach can improve product consistency and reduce the amount of material leaving the circuit before it reaches the required size.

Electric Drive and Variable-Frequency Control

The SP7150VE uses electric drive and an integrated variable-frequency system. For projects with suitable electrical infrastructure, electric drive can make the power arrangement straightforward and can work well with a larger electric crushing and screening line.

The machine also supports remote control, centralized lubrication and intelligent control functions. These features are useful because modern crushing plants are becoming more automated. Operators want to spend less time walking around the machine to check basic operating conditions and more time managing the production process.

Lubrication and Wear Management

Sunward lists thin-oil lubrication and high-quality wear-resistant parts as part of the SP7150VE configuration. From an operating point of view, this is important because wear is a normal part of crushing.

The right question is not whether wear can be eliminated. It cannot. The more useful question is whether wear can be monitored, planned and managed without causing unnecessary production stops.

4. SP7150VE Technical Advantages in a Real Crushing Line

When I discuss a machine with an overseas customer, I prefer to move away from brochure language and talk about what happens on a real site.

Suppose the customer already has a primary jaw crusher and a secondary cone crusher. The material has already been reduced to a suitable feed size. The next target is manufactured sand or better-shaped aggregate. This is where the SP7150VE can become useful.

Its maximum feed size is 45 mm, so the upstream crushing process needs to prepare the material correctly. This is important. A VSI crusher should not be treated as a primary crusher for large quarry rock. Feeding oversized material beyond the specified limit can affect production stability and component life.

Once the correct feed reaches the VSI, the high-energy rotor creates the impact action needed for further size reduction and shaping. The final material then moves through the screening and return system. Oversize material can be returned to the crushing process, while qualified material moves toward the final product conveyor.

Source: Sunward PSR official product specifications for SP7150VE, SP1213IE and SP300CE.

This comparison shows why I would not simply compare capacity numbers when selecting crushing equipment. SP1213IE accepts much larger feed material and is intended for a different stage of the crushing process. SP300CE also works at a different crushing stage. The SP7150VE is much more focused on fine crushing, shaping and manufactured sand production.

That difference becomes especially important when planning a complete plant. A customer may need a jaw crusher for primary crushing, an impact or cone crusher for secondary crushing, and then a VSI crusher for shaping. The machines work together rather than competing with each other.

Closed-Circuit Production

The SP7150VE can be used as part of a closed-circuit process. This is particularly useful when the customer has strict requirements for final product size.

Instead of allowing every particle to leave the crusher immediately, the screening stage separates material according to size. Oversize material is returned, while suitable material continues toward the final product.

This approach gives the operator better control over the finished material and can be especially useful for manufactured sand and high-quality aggregate production.

Site Operation

The official machine data lists a maximum climbing angle of 20 degrees for the travel system. The machine also has hydraulic travel control. However, site conditions always need to be checked before equipment selection and installation.

Ground condition, access roads, working area, electrical supply, material flow and final product stockpiles all influence how practical a crushing plant will be on a particular site.

5. Where Can I Use the SP7150VE?

I would mainly consider the SP7150VE when the production target involves fine crushing, manufactured sand or aggregate shaping.

Quarrying

Quarry operations are one of the most obvious applications. After larger rock has been reduced through primary and secondary crushing, the VSI stage can be used to improve particle shape and produce finer aggregate.

For customers producing several aggregate sizes, the SP7150VE can form part of a complete crushing and screening line. The exact process depends on the raw material and the required products.

Manufactured Sand Production

Manufactured sand is becoming increasingly important in many aggregate markets. Natural sand availability, quality and transport distance can make manufactured sand an attractive option.

The key point is that manufactured sand is not simply “small crushed stone.” The particle shape, grading and fine material content all influence its usefulness. That is why VSI crushing technology is often considered for this stage.

Aggregate Shaping

When a customer already has a crushing line but wants to improve the shape of the finished aggregate, a VSI crusher can be added as a shaping stage.

The SP7150VE is designed for this type of work. Its high-energy rotor and configurable crushing chamber allow the machine to be adjusted according to the material and final product requirements.

Mining

Mining applications can also require fine crushing and material shaping. The correct application depends heavily on the type of ore or rock, feed grading, abrasiveness and required output.

Before we arrange equipment for a mining customer, I would normally ask for material information and production requirements rather than simply recommending a model from a capacity chart.

Infrastructure and Road Projects

Infrastructure projects often need consistent aggregate for road base, concrete, asphalt and other construction uses. A VSI stage can be useful when the project requires improved particle shape or finer aggregate.

For temporary or changing project sites, the complete plant layout also needs to be considered. Transport dimensions, access, power supply and setup requirements can be just as important as the crusher itself.

6. Manufacturing, Inspection, Delivery and Service

For industrial equipment, I believe the purchase process should be more than sending a quotation and waiting for payment. Customers need to know what happens before the machine leaves the factory and how the equipment will be prepared for international transportation.

Ganglong Heavy Industry Technology (Hefei) Co., Ltd. was founded in 2013. Together with Hefei Ganglong International Trade Co., Ltd., we work across construction machinery, mining machinery, agricultural machinery and related equipment. Our international trade team has experience serving customers in Asia, Africa, America and other overseas markets.

For Sunward equipment, we act as a supplier and international trade partner. We do not describe ourselves as the manufacturer of Sunward-branded machines. Instead, our role is to help customers source suitable equipment, confirm specifications, arrange the commercial process and coordinate delivery requirements.

Specification Confirmation

Before production or order confirmation, we first need to make sure the machine configuration matches the customer's working conditions. For a VSI crushing plant, this includes the feed material, maximum feed size, expected capacity, final product requirements, power conditions and related equipment.

Small differences in the process can have a large effect on the final configuration. For example, a customer producing manufactured sand may have different requirements from a customer producing shaped coarse aggregate.

Pre-Shipment Inspection

Before shipment, the machine is inspected according to the order requirements. The inspection normally covers appearance, main functions, hydraulic and electrical systems and basic operating performance.

Standard documents and accessories are prepared according to the confirmed order. If the customer has specific documentation or accessory requirements, these should be confirmed before shipment rather than handled at the last minute.

Payment and Production Schedule

International machinery orders are commonly arranged through T/T, such as a deposit before production and the balance before shipment. The exact payment terms depend on the commercial agreement.

Production time is not a fixed number for every order. It can depend on the model, configuration, order quantity and customization requirements. We confirm the production and delivery schedule with the customer before production begins.

International Shipping

Complete crushing machines are generally transported by sea for international orders. Suitable spare parts and accessories may be shipped by air or express when the size and weight make that practical.

For packing, machines are normally protected with film, fixed securely and prepared according to shipping requirements. Spare parts and loose accessories are packed separately in suitable cartons or wooden cases.

The final packing and delivery method can be adjusted according to destination, shipping route and customer requirements. For overseas customers, this part deserves attention because a good machine still needs to arrive safely and in usable condition.

7. SP7150VE Compared with Other Crushing Solutions

One question I often hear is: “Why should I use a VSI instead of another crusher?” The honest answer is that the machine type should follow the job.

Source: Equipment application descriptions based on Sunward PSR product information for its jaw, impact, cone and VSI crushing equipment.

This is why I would normally build the complete process first and select the crusher second. If the feed is too large for the SP7150VE, the answer is not to force the material into it. The answer is to use the correct upstream crushing stage and prepare a suitable feed.

The same logic applies to capacity. A machine rated at 300 t/h does not automatically mean that every project will produce 300 t/h. Material hardness, moisture, feed grading, chamber setup, operating conditions and final product requirements all affect actual output.

For this reason, our quotation process starts with the application instead of ending with a model number.

Conclusion: Choosing a VSI Crusher Based on the Actual Job

The SP7150VE crawler vertical shaft impact crusher is best understood as a fine-crushing and shaping machine rather than a general-purpose primary crusher. The current Sunward specification lists it as an electric skid VSI crushing plant with a 125–300 t/h processing capacity and a maximum feed size of 45 mm.

Its heavy-duty high-energy rotor, dual-chamber design, configurable rotor options, rock-on-rock and rock-on-metal configurations, grading and dust-removal design, return screen and intelligent electrical controls give it a clear role in manufactured sand and aggregate shaping applications.

From our perspective at Ganglong, the most important part is matching the machine to the complete process. A crusher may look excellent on paper, but the real question is whether it fits the material, feed size, capacity, final product and site conditions.

That is why we prefer to discuss the complete application before confirming a machine configuration. Once the process is clear, we can work through the equipment arrangement, inspection requirements, payment terms, packing and international shipping step by step.

For quarrying companies, aggregate producers, mining contractors and infrastructure projects that need a practical vertical shaft impact crusher for manufactured sand and aggregate shaping, the SP7150VE is a machine worth considering as part of a properly designed crushing circuit.
