Single Roll Crushers by Pennsylvania Crusher Brand

Our single roll crushers employ three distinct methods for reducing coal, petroleum coke, lignite and other friable materials: impact, shear and compression.

Features

Pennsylvania Crusher brand single roll crushers are relatively compact, yet have very large mouths, enabling them to accept large slabs. The curvature of their breaker plates ensures that no large slabs of material can simply fall through the chamber without being crushed to the proper output size.

Single Roll Crusher Models:

  • Type K – suited for the size reduction of materials having a compressive strength of 8,000 p.s.i. or less. Materials crushed typically include coal, petroleum coke, lignite and other friable substances. This model is also employed as a lump breaker for potash, chemicals, salts and similar minerals

Advantages & Benefits:

  • Low Profile - Models easily fit under dump hoppers and in other areas having limited space
  • More Feeding Options - Models may be choke-fed from hoppers, or they may be fed at continuous, controlled rates from vibratory screens, apron feeders or belts
  • Superior Roll Assembly - Teeth cannot come loose from the roll
  • Minimal Fines Production - Material is fractured along its natural cleavage lines at slow speeds
  • No Screen Bars - Prevents sized material from being re-crushed, further reducing fines
  • Low Power Requirement - Toothed rolls revolve at very low speeds
