Features

Higher productivity, higher reduction ratio, larger feeding acceptance and less wearing
Due to the optimal design of the deep V symmetric crushing chamber, and the design of motion structure combined with the crusher speed, the crusher obtains the maximum feeding size, productivity, reduction ration and less wearing. The excellent nip angle makes the smooth rock crushing wish the reduction ratio up to maximum.

Reliable & durable heavy-duty pitman assembly
The pitman is made of high quality cast steel, driven by the heavy-duty cast iron belt wheel and flying wheel. The heavy duty forging eccentric flying wheel shaft and SKF and FAG bearing make the crusher extraordinarily reliable. The pitman is equipped with one interchangeable protection plate; efficiently protect the pitman from the shock of the feeding material.

Robust frame
Robust frame is welded by the front cast steel fixed jaw, side rolling steel plates, and rear cast steel adjustment units. We improve the welding to avoid plate layer failure. After welding, the frame unit will be given one whole annealing, so that the frame is stronger, durable, reliable, and simpler.

Deep symmetric crushing chamber
With nip angle of 18-22, the fixed jaw liner and the pitman liner is the same and can be interchangeable.

CSS (Wedge) adjustment system
Mechanical or hydraulic wedge CSS adjustment system is simpler and safer than the spacer adjustment.

No anchor bolt foundations
No anchor bolt foundations is possible due to the good balance of the crusher. The crusher can operate by the cushion between rubber dampers and stoppers, to efficiently absorb crushing load, avoid the damage to the crusher foundation.

An integral motor base
An integral motor base is mounted on the crusher frame to prolong V-belt life and save the mounting space, the foundation can be more simply, while the standard belt wheel and the flywheel cover can be used.
