Hammermill maintenance for top grinding performance at a lower operating cost
This article explains what routine and long-term maintenance steps you can take to keep your hammermill performing at peak levels while operating at lower cost.
A hammermill is one of the toughest fine-grinding machines at work in today's bulk solids plants. The mill handles a wide variety of friable and fibrous materials, including grains, oil seeds, wood scraps, paper and cardboard, chemical products, plastic and rubber products, limestone, and tobacco. Depending on the hammermill model and components you select, the unit can handle feed sizes up to several inches and, depending on the application, yield ground particles as small as 50 percent passing 50 US mesh (about 0.3 millimeter). The reduction ratio through a hammermill can typically range from 4:1 for a coarse process (such as reducing 10-millimeter feed particles to 2.5-millimeter particles) to 20:1 in a more extreme application (grinding 10-millimeter feed particles to a final size of 0.5 millimeter).
