Mining & Aggregates

Since 1965 P.R. Engineering has been committed to supplying new and re-manufactured jaw crushers to the mining and aggregate sectors. Manufacturing and repairs have included all sizes and makes.

As the sole manufacturer of the Birdsboro Buchnan Jaw Crushers we manufacture both new and used machines to Original Manufacturer's Specifications.

The Birdsboro Buchanan Jaw Crusher was redesigned by P.R. Engineering Limited to accomodate fabricated design versus the old casting type of crusher. This over the years has proven the true strength in design that is required when a tough, hard and/or abrasive crushing is the makeup of your rock. The fact that a double toggle (blake type) crusher is the proper application when you don't have the soft material or don't require portability, your liner changes and downtime is greatly reduced due to the fact that the rubbing and scrubbing motion that a single toggle crusher offers is not a factor. Some operators when selecting a crusher may not be aware of the fact that rubbing and scrubbing in the crusher chamber is what leads to excessive premature wear on their manganese. Impact is what hardens manganese and this is the motion a double toggle crusher offers. Other features include:

  • Removable greasable toggle ends
  • The only double toggle manufacturer to offer a HYDRAULIC TOGGLE
  • High tensile fully machined all over Manganese Steel or Bronze Toggle Seats
  • Easy adjustment for discharge setting and stroke adjustment to suit your material
  • No bluing of shaft in the babbiting bearing should you choose Babbit bearings

We also offer the same warranty on both new and used equipment.

Since becoming an authorized Metso Repair Center we have now expanded our equipment to include the rebuilding and repairs of Cone and Gyratory Crushers.
