What equipment is used for processing granite gravel?

Granite is hard in texture and highly wear-resistant, making it a high-quality raw material for construction aggregate. Its processing involves multiple procedures including crushing, screening, sand making and conveying. The supporting equipment must meet the demand of high-intensity operation. The core machines are listed as follows:

1、Jaw Crusher

As the key primary crushing machine, it mainly handles large raw granite stones. It crushes raw materials into medium particle size through extrusion between the movable jaw and fixed jaw. With simple structure, low failure rate and large feeding opening, it is perfect for the first crushing of granite and an essential machine for the production line.

2、Cone Crusher / Impact Crusher

The cone crusher adopts the laminated crushing principle, with uniform finished grain shape and low flaky particle content. It is suitable for fine crushing of high-hardness granite, and widely used in projects with high requirements for aggregate quality.

The impact crusher uses impact crushing to produce well-shaped finished products, ideal for construction aggregate that demands strict grain quality, yet its wearing parts wear out relatively faster.

3、Sand Making Machine (Impact Crusher)

If you need to produce manufactured granite sand, the sand making machine is the core equipment. Through high-speed impact and grinding, it processes crushed stone into standard construction sand. It can also reshape stone grains to improve the overall quality of finished aggregate.

4、Vibrating Screen

It is used for grading and screening. According to different screen hole sizes, it separates crushed stone into various specifications of stones and sand for classified collection. It ensures the finished particle size meets customer requirements, and sends unqualified materials back for re-crushing.

5、Auxiliary Supporting Equipment

It includes feeder (supplies materials evenly to keep the crusher running stably), belt conveyor (connects all processing equipment for material transportation), sand washing machine (removes soil and dust from sand and stone to improve cleanliness), dust collector (controls production dust to meet environmental protection standards) and other machines.
