The Lancaster Model 24×32 Roll Crusher is used extensively throughout the world in the glass manufacturing industry where high quality and reliable service are required.
A smaller Model 12×18 Roll Crusher is available with a capacity of up to 3 tons per hour.
How It Works
The crushing rolls turn toward each other, confining all crushing to the area where the teeth mesh. Both rolls are timed to rotate at the same speed to maintain a true crushing action with minimum fines.
All material entering the crusher must pass through the mounted twin shaft rolls. Relative positions of shafts are rigidly fixed. Trapped material will not separate the rolls. This prevents oversize material from passing through the crusher. Crushed particle size can be varied by changing the distance between the twiin crushing rolls.
The Lancaster Model 24×32 Roll Crusher is a compact unit built around a rigid cast frame, housing double rollers. It is powered by a 20Hp VFD gear drive unit. The high alloy steel shafts are driven by a heavy-duty chain operating in an enclosed oil bath. All parts coming in contact with the process material are replaceable and are made of wear-resistant alloys. Replaceable comb plates and cheek plates at the ends and sides of the housing prevent material from bypassing the rolls.
Crushing teeth are cast of a hard and tough alloy in replaceable segments. The large over-sized bearings are outboard, self-aligning and protected by mechanical seals. Protection from shock loads is provided through the VFD.
Top and bottom openings have drilled mounting flanges. The crushing gap is adjustable by shimming the pillow blocks. Relative positions of shafts are rigidly fixed. Trapped material will not separate the rolls. This prevents oversize material from passing through the crusher.
Shaft outlets in the frame are equipped with mechanical seal assemblies. Over-sized, sealed, spherical roller bearings are supported by large castings rigidly mounted to the crusher frame castings and remotely located from the crushing area.
