1. PAINPOINT DRIVEN OPENING

Are you managing grinding circuit inefficiencies that directly impact your bottom line? Common operational challenges with traditional ball mills include excessive liner wear requiring frequent, costly shutdowns, inconsistent grind size affecting downstream recovery rates, and high specific energy consumption driving up operational costs. Unplanned downtime for maintenance can cost tens of thousands per hour in lost production. Are you questioning how to improve mill availability, achieve a more uniform particle size distribution, and reduce your overall cost per ton milled? A purposeengineered ODM ball mill solution addresses these exact pain points.

2. PRODUCT OVERVIEW

This equipment is a customengineered ODM (Original Design Manufacturer) ball mill for continuous, heavyduty grinding in mineral processing and industrial milling operations. The operational workflow involves: 1) Feed material introduction via a trunnion or girth gear drive system, 2) Cascading and attrition of grinding media (balls) within the rotating shell to reduce particle size, 3) Discharge of ground material via peripheral or overflow mechanisms. Its primary application scope is the fine and regrind milling of ores, cement clinker, and industrial minerals. A key limitation is its design for specific feed sizes and moisture content; it is not suitable for primary crushing of large rock feed.

3. CORE FEATURES
