Designed with a high speed rotor and hinged steel hammers, Minimacs crush between the hammer face and perforated steel screen plates. They typically produce an ASTM standard 100% -4 Mesh, 95% -8 Mesh at up to 15 TPH in coal.

They are widely recognized as the standard in Sample Crushers because of quality features such as the hinged access door, reversible hammers and easy-to-change screen plates. Minimac Hammermills can be used in a wide range of applications. A variety of screen plate perforation sizes are available.
