1. PAINPOINT DRIVEN OPENING

Are you managing inconsistent gold recovery rates that leave valuable micron gold in your tailings? Struggling with frequent mechanical failures in harsh, abrasive processing environments that halt your entire operation? Facing escalating operational costs from high energy consumption, excessive water usage, and constant replacement of wear parts? These challenges directly impact your bottom line, turning potential profit into preventable loss. How can you increase overall recovery efficiency while simultaneously reducing downtime and total cost of ownership? The solution lies not just in equipment, but in precisionengineered ODM gold mining equipment designed for maximum reliability and yield.

2. PRODUCT OVERVIEW

This product line encompasses specialized ODM gold mining equipment for gravity separation and concentration, specifically centrifugal concentrators. The operational workflow is engineered for efficiency: 1. Ore slurry is fed into a rotating drum. 2. High centrifugal force separates highspecificgravity gold particles from lighter gangue material. 3. Concentrated gold is collected in an internal groove system. 4. Automated or manual discharge cycles recover the concentrate. 5. Tailings are continuously evacuated for further processing or disposal.

This equipment is applied primarily in alluvial (placer) and hard rock mining operations for free gold recovery, as a primary concentrator or for upgrading existing concentrates. Its limitations include reduced efficacy on ultrafine (sub50 micron) gold without preclassification and a dependency on proper feed preparation (particle size and slurry density).

3. CORE FEATURES
