project instruction:

This project is a fully enclosed and environmentally friendly large-scale gravel production line to protect green waters and green mountains, provide high-quality aggregate resources for various fields, implement environmental protection policies, and build green mines.

Materials: The main stone is granite, including some quartz stone, limestone, etc.; output is 1,000 tons/hour;

Main crushing equipment:

Two vibrating feeders WL1350

Two European version jaw crushers PEV950x1250

A spring cone crusher HJC2150

Three single-cylinder hydraulic cone crushers CH660

Two vertical shaft impact crushers (sand making machines) GPR12000

Two fine sand recovery integrated machines TD2445x2

Eight vibrating screens YA3080

Eight sand washing machines XSD3620

Six dewatering screens TD2445

Brief description of crushing process:

First, the stone is evenly and continuously sent to the European jaw crusher for preliminary crushing under the action of the vibrating feeder; the coarsely crushed stone is sent to the spring cone crusher by the belt conveyor for re-crushing; fine crushing The final stone is screened by a vibrating screen to separate materials with different particle sizes; it enters the sand washing machine and is dehydrated to separate natural sand.

Secondly, the stones separated by the first vibrating screen are sent to the single-cylinder hydraulic cone crusher by the belt conveyor for re-crushing. The stones are separated by the second vibrating screen and sent back to the feeder and single-cylinder hydraulic cone crusher for crushing. The finished material is screened out through the sand washing machine and dewatering, and the other part is sent to the sand making machine;

Then, the sand making machine crushes and sends them back to the vibrating screen for separation. Part of the separated stones enters the sand washing machine and dehydration screen to remove the finished materials, and the other part is sent to the sand making machine;

Finally, the stones that meet the needs of the three processes are transported to the vibrating screen through the belt to produce finished materials.

Advantages of crushing production line:

It is suitable for crushing various large pieces of soft and medium-hard sand and gravel aggregates, with large feed particle size, wide adjustment range of the discharge port, relatively simple process flow, convenient operation process, and low initial investment cost;

 It is suitable for crushing various medium hardness and brittle materials, and has a certain shaping effect. It is designed according to the material requirements and characteristics of large-scale projects, which greatly improves the production efficiency and the continuous grading of aggregate finished products, and effectively provides better follow-up. raw materials;

 Lucid waters and lush mountains are invaluable assets. If you open a gravel factory, the design of the entire crushing production line is not only scientific and reasonable, but also equipped with environmentally friendly crushing equipment. The interior adopts a fully enclosed structure and enhanced sealing to solve the problems of dust and noise from the equipment itself. Passed environmental protection assessment.
