- Choice of interchangeable perforated screens or bar grates dependent upon application
- Heavy duty perforated plate or bar grates made from abrasion resistant steel
- Small diameter screens provided with support backings for longer life
Screens and bar grates are the key factor in determining the consistency of the finished particle size. Positioned over the discharge opening, the screen or bar grate ensures that no material evacuates the grinding chamber until it meets the target finished particle size.
