Lancaster Products Roll Crushers reduce difficult-to-crush material in a single pass.

Lancaster Products Roll Crushers are designed for long life with a minimum of maintenance. These crushers reduce – in a single pass- material previously requiring primary and secondary crushing. 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 – and highly effective – crushing action.

CONSTRUCTION

Lancaster Products Roll Crusher

The Lancaster Products Roll Crusher is a compact unit built around a rigid cast frame. It is powered by a 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 oversized bearings are outboard, self-aligning and protected by mechanical seals.
  • Protection from shock loads is provided through the VFD.
  • Shaft outlets in the frame are equipped with mechanical seal assemblies.
  • Oversized, sealed, spherical roller bearings are supported by large castings rigidly mounted to the crusher frame castings and remotely located from the crushing area.

HOW IT WORKS

Lancaster Products Roll Crusher rolls rotate 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.
  • All material entering the crusher pass through the mounted twin shaft rolls.
  • Since the relative positions of shafts are rigidly fixed, any trapped material will not separate the rolls. This prevents oversize material from passing through the crusher.
  • Crushed particle size can be varied from ¾ inch to 2 inches by changing the distance between the twin crushing rolls. Top and bottom openings have drilled mounting flanges. The crushing gap is adjustable by shimming the pillow blocks.

Operational Life Expectancy of Lancaster High-Intensive K-Series Mixers

Lancaster Products High Shear Counter-Current Mixers are highly effective in their ability to mix and pelletize in one machine and one process, but Lancaster Mixers are also built to last. Many of our machines are still operating after decades of use. We continue to supply parts to many vintage year machines still in operation.

High Shear MixerLancaster Products machines are built with a robust construction that provides structural durability and are designed to allow for replacement of wear parts as needed to extend the operational life of our machines instead of total machine replacement. To our customers this translates to lower Total Cost of Ownership and higher return on investment than other mixers. With proper maintenance, Lancaster Products mixers are very long-lived machines.
