For rock crushing, aggregate production and recycling

The Groundworx Co. is capable of satisfying the overwhelming demand for dependable, high-quality crushing equipment. There are different types of crushers; determining the equipment you need requires experienced consideration (learn more about choosing the right crusher for the situation).

Jaw Crushers are typically used for primary crushing; taking your biggest feed material and crushing it to a more manageable size. They can be used in a variety of processes and thrive in aggregate and recycling applications.

The general design of a jaw crusher has not changed in over a century. There is a stationary plate that is fixed inside of a box and a moving plate that compresses material against the stationary plate. As material is crushed, it falls out the bottom.

Over the years there have refinements to jaw crushers to make them more efficient, more safe, and more serviceable.

Jaw Crushers We Distribute


Minyu Jaw Crushers are widely recognized as one of the most successful jaws on the market today. Longer jaw dies and reduced nip angle easily produce more tonnes per hour, with no blowback. All units come standard with dual balance fly wheels, dual toggle rods, and hydraulic assisted adjustment. These units are fed by vibratory grizzly feeders or prescreen decks.

Units are mounted at a 7-degree angle towards the feeder to assist in even feeding. Toggle seats are bolt-in, jaw dies are reversible, and all bearings run in oil. Minyu Jaw Crushers are available mounted on multiple axle chassis or on tracks. Drive train options include diesel engines or electric motors.
