What are the main crushing equipment in a gravel yard?

Gravel is not done by a machine, but requires a production line. The usual production line configuration includes the following equipment: feeding equipment, first-level coarse crushing equipment, second-level medium and fine crushing equipment, screening equipment, and conveying equipment (if you have sand making needs, you can equip sand making equipment and sand washing equipment) , we are mainly talking about several types of crushing equipment today.

1、Jaw Crusher

Feed particle size: ≤1200mm

Production capacity: 1-1000t/h

Finished product specifications: 10-350mm

Scope of application: Jaw crusher is a common head crushing equipment. It is used for first-level coarse crushing of materials. It can crush more than 200 kinds of soft and hard materials, such as granite, limestone, river pebbles, coal gangue, etc.

Performance advantages: The overall structure of the equipment is reasonable, and the cubic appearance occupies a small area; the deepened "V"-shaped crushing cavity allows for no dead ends in crushing, and the particle size of the finished product is more uniform; high wear-resistant materials make the equipment more durable.

Common types: CJ European version jaw crusher, HD German version jaw crusher; PE jaw crusher

2、cone crusher

Feed particle size: ≤560mm

Production capacity: 27-2181t/h

Finished product specifications: 3-64mm

Scope of application: Cone crushing is mainly used for secondary medium and fine crushing of hard materials. It can process various ores and rocks with Platt hardness f≤5-16 and above medium hardness, such as river pebbles, basalt, granite, etc.

Performance advantages: The cone crusher adopts the lamination principle for crushing operation, with a large crushing ratio and good finished product effect; it has an overload protection system, which will be triggered when encountering something difficult to crush, effectively protecting the equipment and reducing the cost of the equipment. failure rate.

Common types: single-cylinder cone crusher, multi-cylinder hydraulic cone crusher, fully hydraulic cone crusher, compound cone crusher

3、Impact Crusher

Feed particle size: ≤1300mm

Production capacity: 30-2000t/h

Finished product specifications:<250-<800mm

Scope of application: Using the impact crushing principle, it is suitable for finely crushing medium and soft materials with a side length of 100-500mm and a compressive strength not exceeding 350MPa, such as limestone, calcite, dolomite, construction waste, etc.

Performance advantages: The particle size of the finished product of the impact crusher is controllable. The gap between the impact plate and the impact hammer can be freely adjusted. The needle flake content of the impact crusher product can be less than 10%. The finished product has good particle shape and uniform particle size. .

4、hammer crusher

Feed particle size: ≤1200mm

Production capacity: 100-3000t/h

Finished product specifications: ≤25-≤35mm

Scope of application: Because the hammer crusher uses the impact principle for crushing, the wear of the hammer head is very high. Therefore, compared with hard materials, the hammer crusher is more suitable for crushing medium hard materials with a compressive strength of less than 200MPa. The finished materials can Adjust according to needs, coarse, medium and fine specifications are available.

Performance advantages: When talking about hammer crusher, we have to mention its characteristic of crushing and forming in one time, which can effectively reduce production costs and is widely used in the market.

Common types: ordinary hammer crushing, PCZ heavy hammer crushing, PCX hammer crushing
