How to adjust impact crusher outlet?

Impact crusher is an importatant crushing equipment in various ore crushing, railway, highway and construction industry artificial sand and gravel production plant due to the good shape outout size. The impact crusher can adjust the output particle size in various ways, such as adjusting the rotor speed, adjusting the gap between the impact plate and the grinding chamber, etc. The gap adjustment can be adjusted mechanically or hydraulically, and the hydraulic adjustment system can be used to easily adjust the gap through the local operation button or the travel control system.

1. Adjust the rotor speed

The impact crusher relies on the kinetic energy generated by the rotor to impact the material. Therefore, when the input power is constant, the rotor speed is proportional to the size of the output particle size. Therefore, the impact crusher can realize the adjustment of the output particle size by adjusting the speed of the rotor. adjust.

2. Adjust the gap between the impact plate and the blow bar

By adjusting the size of the gap between the impact plate and the blow bar, the number of impacts of the material can be changed, thereby affecting the composition of the particle size of the product to varying degrees. When adjusting the accessories of the front impact frame, remove the front screw sleeve first, and then use the M56 nut to twist clockwise, so that the gap can be adjusted by a large part. If it is twisted against the trend, the gap can be adjusted by a small part. The discharge particle size is controlled by adjusting the distance. The smaller the distance, the smaller the discharge particle size. At present, most impact crushing stones are equipped with hydraulic devices, which can easily adjust the gap between the impact plate and the blow bar.

It should be noted that the rotation direction of the counterattack is irreversible, and the gap between the counterattack plate and the blow bar should be gradually reduced according to the work needs. After adjustment, the rotor should be turned for several turns by hand to check whether there is any impact. In addition, according to the installation height of the impact crusher, the connection between feeding and discharging should be done well.
