The output particle size of an impact crusher can be adjusted in the following ways:

1. Adjusting the rotor speed or diameter. Increasing the rotor speed, or increasing the rotor diameter while maintaining the same speed, can extend the crushing time, thereby adjusting the product particle size, increasing output, and improving material crushing efficiency.

2. Changing the product particle size by adjusting the distributor. Adjusting the distributor opening to a smaller size increases the overflow flow rate, limits the collision movement of material within the crushing chamber, shortens the residence time of material particles in the crushing chamber, and improves the crusher's throughput capacity.

3. Adjusting the grinding chamber gap to change the finished product particle size. The grinding chamber gap adjustment of the Maikelu impact crusher is primarily hydraulic, allowing for quick and convenient adjustment via buttons or a control system.

Impact crushers produce products with a fine shape and uniform particle size, and are widely used in hydropower, highway, construction waste disposal, and the processing of artificial building aggregates.
