The impact crusher has reliable and stable operation. The output of the impact crusher can reach 30-2000t/h. It is often used in stone production lines with a jaw crusher. The side length can be 100-500mm, and the compressive strength will not be stained. The medium and brittle materials of 350MPa are finely crushed and processed. It has the advantages of large crushing ratio, good material size after crushing, and diversified crushing specifications. This is due to its various adjustable and controlled output particle types and particle sizes. The method will be introduced in detail next.

1, Adjust the speed of the rotor
The impact crusher mainly relies on the impact energy of the high-speed rotation of the rotor to mechanic y crush the materials to be processed into the crushing cavity. Therefore, adjusting the rotation speed of the rotor can efficiently control the output particle size.

2, Adjust the gap between the counterattack board and the hammer
Through the adjustment of the discharge gap, the number of impacts of the material can be changed, so as to realize the adjustment of the particle size of the material. The method of gap adjustment varies according to the type of equipment, and is mainly divided into two adjustment methods:

（1）Hydraulic adjustment The equipment equipped with hydraulic device can easily adjust this action through the operation button or remote control system. The main shaft is located on the plunger in the hydraulic cylinder, and the upper and lower positions of the crushing cone can be changed by changing the volume of hydraulic oil under the plunger. , Thereby changing the size of the discharge port.

(2) Mechanical adjustment This kind of impact crusher is equipped with an adjustment nut above the main shaft of the equipment, and the adjustment nut is operated, and the crushing cone is enough or rises, so that the discharge port becomes larger or sm er. Of course, depending on the model, there will be some other ways to adjust the machine port, just follow the operating instructions.
