Bradford Breakers by Pennsylvania Crusher Brand

Bradford Breakers are used at mines around the world to crush, size and clean run-of-mine coal and other friable materials.

Features

Maintenance costs are surprisingly low with few servicing requirements, other than periodic lubrication and inspection. Because of their rugged design, downtime is rare, eliminating any need for back-up machines.

Advantages & Benefits:

  • Simultaneous sizing and cleaning.
  • Sized coal exits quickly through the holes of the screen plate.
  • Unsized coal continues through the length of the crushing chamber.
  • Since this is gravity impact, breakage occurs along natural cleavage fractures, so there is very little production of fines.
  • Internal deflectors induce such material to flow out of the cylinder onto a refuse belt or pile.
  • Maximum cylinder strength and rigidity.
  • T-beams provide maximum rigidity and while being less prone to build up and corrosion.
  • Because of the great strength of our cylinder, it is driven from only one end.
  • Screen plates are lap-mounted and double-bolted, giving them great strength and rigidity.
  • Screen plates are fully interchangeable throughout the cylinder.
  • Several shapes of sizing holes, including a self-cleaning design that minimizes plugging available.
