A 1000 TPH aggregate line has to do more than crush rock. It needs stable feeding, efficient size reduction, accurate screening, good particle shape, clean finished products and controlled fine sand recovery.
In Gansu, China, Leimeng supplied a customized tuff aggregate production line for a client with a high-capacity production target. The project is designed around tuff processing and combines primary crushing, cone crushing, VSI shaping, multi-stage screening, sand washing and fine sand recovery into one complete process.
The result is a practical crushing and screening solution built for stable output, better aggregate shape and multiple finished product sizes for road construction, municipal engineering and concrete production.
Why Tuff Needs a Customized Crushing Process
Tuff can be a good raw material for aggregate production, but it still needs the right crushing process. Its hardness, moisture content, porosity and weathering condition may vary from site to site. Because of this, the same equipment layout may not perform equally well in every quarry.
If the crushing and screening system is not properly matched, the plant may face unstable output, excessive fines, high circulating load, poor particle shape or unnecessary wear. For a high-capacity plant, these problems can quickly affect production cost per ton.
That is why Leimeng designed the Gansu project as a complete process instead of a simple equipment combination. From primary jaw crushing to cone crushing, VSI shaping, screening, washing and fine sand recovery, each stage was selected to match the material characteristics and the client’s 1000 TPH capacity requirement.

This configuration reflects a system-level design. The jaw crusher handles large feed material, the cone crushers control medium and fine crushing, the VSI crusher improves particle shape, and the vibrating screen separates different aggregate sizes. After that, the washing and fine sand recovery system helps improve cleanliness and reduce material loss.
How the Crushing Process Works
Primary Crushing with GC160 Jaw Crusher
The GC160 jaw crusher is used as the primary crusher. Its job is to reduce large tuff blocks into a size that can be handled smoothly by the downstream cone crushers.
A stable primary crushing stage is important for the whole plant. If the discharge from the jaw crusher is too uneven, the cone crushers may face unstable load, higher wear and reduced production efficiency. In this project, the jaw crusher provides a steady foundation for the following crushing stages.
Cone Crushing with DH780 and HPY500B
The DH780 single-cylinder hydraulic cone crusher and HPY500B multi-cylinder hydraulic cone crusher are used for medium and fine crushing. This two-stage cone crushing arrangement helps control particle size before the material enters shaping and screening.
Cone crushing is suitable for aggregate plants that need stable discharge, controlled reduction and continuous operation. By matching the two cone crushers with the upstream jaw crusher and downstream screen, the Gansu line can reduce unnecessary recirculating load and improve overall process stability.
VSI Shaping and Sand Making with LM10000
After cone crushing, part of the material still needs better particle shape or further fine crushing. The LM10000 vertical shaft impact crusher is used for shaping and sand making.
For road construction and concrete applications, aggregate shape matters. Better-shaped particles can improve packing performance and make the final product more suitable for commercial aggregate use. In this production line, the VSI crusher helps improve the value of finished aggregates and manufactured sand.
Screening, Washing and Fine Sand Recovery
Screening is not just a support process. In a high-capacity aggregate plant, the vibrating screen directly affects product grading, circulating load and crusher performance.
The 3YKJ3075A three-deck double-shaft vibrating screen separates crushed material into different product sizes. This allows the plant to produce multiple aggregate specifications from the same raw material.
The 2LSX1580 double spiral sand washer removes impurities from sand and aggregate, while the ZKX3053-D2C fine sand recycling machine helps recover useful fine particles during washing. This is important for manufactured sand production, because fine sand loss can reduce yield and affect final product grading. A well-matched fine sand recycling system also supports better material recovery and more efficient sand washing operation.
Automation, Process Control and Plant Layout
Beyond equipment selection, stable aggregate quality also depends on how the entire plant is controlled and arranged on site. In the Gansu project, Leimeng focused on process coordination, automation and layout efficiency to support continuous high-capacity production.
The production line is designed with centralized control, allowing operators to monitor key parameters such as feed rate, crusher load, screen efficiency and sand washing performance in real time. This helps reduce manual intervention and improves overall operational stability.
In addition, the plant layout is optimized to shorten material transfer distances and reduce unnecessary conveying loops. A more compact and logical layout not only improves efficiency, but also helps lower energy consumption and maintenance workload.
By combining equipment performance with process control and layout planning, the production line can maintain stable output, consistent product quality and smoother day-to-day operation.
Built for Efficient and Cleaner Aggregate Production
For modern aggregate producers, sustainability is closely connected with operating cost. A plant that reduces unnecessary recirculating load, avoids over-crushing and recovers more useful fine material can support both environmental goals and better production economy.
In this project, washing and fine sand recovery are important parts of the process. They help improve product cleanliness, reduce material waste and support more responsible aggregate production. For the client, this means the plant is designed not only for capacity, but also for long-term operating stability.
Where the Finished Aggregates Can Be Used
After commissioning, the Gansu tuff aggregate production line can produce multiple sizes of aggregates and manufactured sand. The finished products can be used in:
· Road construction
· Municipal engineering
· Concrete batching plants
· Infrastructure projects
· Commercial aggregate supply
For local infrastructure development, a stable aggregate supply is important. A well-designed production line can help reduce dependence on outside aggregate sources and improve material consistency.
Leimeng’s Role in the Gansu Project
Leimeng provided more than equipment for this project. Before finalizing the process, the technical team reviewed the raw material, site conditions and the client’s 1000 TPH production target.
The complete solution reflects Leimeng Group’s experience in quarry, mining and aggregate production projects. From process design to equipment matching, the goal is to help the client build a stable, efficient and cleaner production line that can support long-term operation.
FAQ
Q1: What is a tuff aggregate production line?
A tuff aggregate production line is a crushing, screening and washing system used to process tuff rock into different sizes of aggregates and manufactured sand.
Q2:What equipment is used in a 1000 TPH aggregate plant?
A 1000 TPH aggregate plant usually needs feeders, jaw crusher, cone crushers, VSI crusher, vibrating screens, sand washer, fine sand recovery equipment and conveyors. The final configuration depends on the raw material, capacity, site layout and product requirements.
Q3: Why use jaw crusher and cone crusher together?
The jaw crusher handles large feed material in the primary stage, while cone crushers reduce the material further in the medium and fine crushing stages. This combination helps improve crushing stability and product size control.
