With a solid reputation of providing the mining industry with the manufacturing and re-build of rugged, dependable jaw crushers for almost 50 years, PR Engineering has taken it’s proven design technology to a new level – by downsizing!

Due to market demand, a miniature version of their industry-leading Birdsboro Buchanan crusher was developed to provide users with the performance of a production crusher in a lab-sized package, and a fraction of the cost.

The PREMAC1 is the only crusher in its class that features double-toggle action. This means better crushing performance, resulting in a more consistent final product with less effort to crush the same amount of rock and reduce wear on moving parts.

Weighing in at just 2,300 pounds, it is a portable, robust, 6’ x 10’ crusher that is ideal for sampling stations, pilot plants, prospecting, exploration, labs and quarries, and for use in adverse conditions where smaller lab crushers would be ineffective.

The PREMAC1 Mobile Access Crusher with sealed roller bearings provides reliable operation with minimal maintenance. High precision machining and assembly ensures smooth operation with minimal vibration. Anti-vibration mounting isolates crusher base from the support frame, thereby eliminating vibrations.

Its just part of the line of custom engineered solutions designed by PR Engineering to solve all types of crushing problems. After all, size matters!
