The HM Series Hammermills are designed for the most demanding operations and are the ultimate in grinding equipment. These rugged, high-efficiency hammermills feature high-density frames that are designed to minimize noise and vibration. They also feature the air-swept teardrop design and our patented regrind chamber. HM Series Hammermills have one-piece, full-access doors mounted on unique pivoting arms to allow the doors to move completely out of the way during service.
