What crusher is good for hard rock

Stone is a small rock body shed by the large rock body encountered external forces, many types, different hardness, usually according to the compressive strength and Mohs hardness to grade, there are soft rock, medium hard rock and highly hard rock, so what is the method of crushing hard stone? What crusher is good for hard rock?

Currently on the market crusher has extrusion type, laminated crushing type, hitting type, stone hitting stone and stone hitting iron and other crushing methods, of which the extrusion type and laminated crushing type are more suitable, because the hitting type is easy to damage the crushing hammer, the use of short life.

1. Extrusion crushing:

The two jaw plates of movable jaw and static jaw form the crushing cavity, simulating the movement of two jaws of animals to complete the crushing operation, the motor drives the belt and pulley, and makes the movable jaw move up and down through the eccentric shaft, when the movable jaw rises the angle between the elbow plate and the movable jaw becomes larger, thus pushing the movable jaw plate to approach the fixed jaw plate, and meanwhile the material is crushed or split to achieve the purpose of crushing; when the movable jaw goes down, the angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate is pushed to approach the fixed jaw plate under the action of tie rod and spring. When the movable jaw moves downward, the angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the tie rod and spring, and the crushed material is discharged from the lower mouth of the crushing cavity.

2. Laminar crushing:

The motor drives the eccentric sleeve to rotate through the transmission device, the moving cone is forced to rotate under the eccentric sleeve, the section of the moving cone near the static cone becomes the crushing cavity, the material is crushed by the multiple extrusion and impact of the moving cone and the static cone, and when the moving cone leaves the section, the material that has been crushed to the required particle size will fall down under the effect of its own gravity, and be discharged from the bottom of the cone.

What crusher is good for hard stone?

What is the best crusher for hard stone? So the general choice of jaw crusher and cone crusher and other equipment is better, that is, to meet industry standards, but also in line with the use of demand.
