1. The equipment has stable and reliable operation performance, convenient maintenance, small volume, light weight, simple structure and convenient movement.

2. Change the three-stage crushing into two-stage crushing, with large production capacity, long service life of hammer head, environmental protection and energy saving.

3. It is used for the fine crushing of raw materials such as granite, basalt, cement clinker, quartzite, emery, ore, iron ore, bauxite and river pebble, so as to overcome the disadvantage that the traditional sand making equipment only uses raw materials of soft rock (below 150MPa).

4. The unique impact lining plate of high chromium plate hammer breaks hard rock, and the particle size of discharge can be adjusted to simplify the crushing process.

5. Energy saving and high efficiency, reduce investment expenses, low damage rate of accessories and convenient maintenance.

6. The finished sand is cubic and has strong compressive capacity. It is suitable for high standard buildings. The particle size of primary finished products ≤ 5mm accounts for more than 85%.

During operation, driven by the motor, the rotor rotates at high speed, and the materials enter the first crushing chamber for crushing, impact and crushing with the plate hammer on the rotor, then enter the second fine crushing chamber for crushing, and finally discharge from the discharge port.
