ReturnGlass - The Lancaster crusher

The Lancaster Model 24x32 Roll Crusher is used extensively throughout the world in the glass manufacturing industry where high quality and reliable service are required.

This Single Pass Material Crusher is designed to reduce materials of a given product size to a minimum size of 95 percent minus 3/4 inch, at rates up to 30 tons per hour. Provisions are made to permit particle size variation from 3/4 inch to 2 inches. Properly installed and operated, this crusher can reduce, in a single pass, material previously requiring primary and secondary crushing. Lancaster Roll Crushers are made for long life with a minimum of maintenance. The 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.

These crushers are used extensively in the primary glass industry for cullet production and for applications such as clinker crushing and fired brick crushing.

Crushing teeth are cast of a hard and tough alloy in replaceable segments. Bearings are outboard, self-aligning and protected by mechanical seals. Both motor and drive are protected against damage from shock loads by a fluid coupling.

The Lancaster Model 24x32 Roll Crusher is a compact unit built around a rigid cast frame, housing double rollers. It is powered by a 20Hp electric motor through a fluid coupling and spur gear reducer. Shafts are driven by a heavy-duty chain operating in an enclosed oil bath. Replaceable comb plates and cheek plates at the ends and sides of the housing prevent material from bypassing the rolls.

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. Sealed, adapter-type, spherical roller bearings are supported by bearing-supported castings remotely located from the crushing area.
