Bradford Breakers.

Rugged, Reliable Operation.

 

Bradford Breakers, widely used at mines and coal prep plants, perform simultaneous sizing and cleaning of ROM coal.
Introduced by Pennsylvania Crusher in the early 1900s, their design has undergone important improvements while providing decades of reliable service, making them the most widely accepted breakers in use. In fact, units over 60-years-old are in regular service today. 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.

 

Comprehensive Support Services 

We offer installation supervision and training. Plus, every Bradford Breaker is supported by our highly responsive parts and service team. When ordering parts, the most current design will be provided. We can also tailor a service or resupply program to your exact needs.

 

Design Advantages

In a breaker, cylinder strength is most important. We obtain maximum cylinder strength and rigidity by overlapping the screen plates, by drilling closetolerance bolt holes with numerically-controlled equipment, and by using high-strength bolts. This provides a significant improvement over older designs made of cast plates which cannot be precisely machined and must be ground by hand.
Additionally, our T-beams provide maximum rigidity while being less prone to build up and corrosion. For maintenance, they afford far easier access to the screen plate bolts than the H-beams used by others.
The drive assembly is uncomplicated and troublefree, allowing the use of a single, normal starting torque motor. Because of the great strength of our cylinder, it is driven from only one end. This eliminates the need for an additional jack shaft to balance torque and to drive both ends of the cylinder.
Most important is the method by which our screen plates are fabricated and mounted. These are lap-mounted and double-bolted, giving them great strength and rigidity. The plates are produced on numerically-controlled equipment with such precision as to be fully interchangeable throughout the cylinder. This also enables them to be retrofitted more easily in the field with no troublesome fit problems.
We offer several shapes of sizing holes including a self-cleaning design that minimizes plugging.
