Uptime vs. Upkeep

The high-abrasion package enhances the natural wear resilience of our horizontal grinders. Our unique grinding chamber design keeps wear focused on replaceable parts, not on permanent surfaces like the grinding chamber walls. The infeed minimizes spillage and abrasion. With these unmatched advantages, you spend less time on maintenance and more time running your grinder and making the profitable end products you need.
