The design of open-able crushing chamber, hydraulic hoisting device and maintenance hang bracket makes it easier to replace wearing parts like hammers, reducing maintenance shutdown period, thus bring cost reduction.

The output size can be changed quickly by hydraulic adjusting device to adjust the gap between impact rack and plate hammer. This design would save the maintenance time. It is easy and convenient even for a few experienced operator.

Adopting the design of heavy-duty bearing, Integral cast steel bearing seat, and increased radial force. It shows excellent performance in water proof and dust proof, The service life of bearing was prolonged.

Adopting heavy-duty rotor design, which enable its owns greater rotatory inertia. That means, with the same rotate speed, it has stronger crushing force, high efficiency.

Adopting wedge block to fix the plate hammer, it is faster to replace the plate hammer and the solidity is greatly enhanced.

Arc shaped plate hammer guaranteed vertical striking between stone and impact bracket, Which brings high crushing efficiency and reducing the capacity decline caused by worn impact hammer.

The lever of the impact frame adjustment device is marked with a scale, which can easily grasp the distance between the plate hammer and the impact frame.

The design of constant tension device maintains constant counter force, decrease the power consumption.
