scats means material in a ball mill or sag mill that has become rounded and no longer susceptible to additional size reduction. Basically, this material may be rejected from the grinding circuit for additional crushing because it contributes to higher energy consumption within the mill. Sample 1 Sample 2 Sample 3. Based on 11 documents.

The oversize or scats are rehandled to the stockpile and recrushed. The primary mill discharge feeds to two parallel single stage overflow type ball mills ( m diameter by m EGL) with a power rating of 4,500 kW each, operating in closed circuit with a dedicated cluster of twelve 250 mm hydrocyclones, of which eight are typically in use.

Lower operating cost. Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency . With the Vertimill® simple and robust design, limited liner replacement is required.

Mt Muro sold 25,558oz of gold and 71,697oz of silver for the six months to June 2008. While mining operations performed well and delivered over 35,000oz Au to the ROM, the plant only managed to convert 23,200oz Au of ore to leach feed. This resulted in a large buildup of highgrade scats inventory on the ROM, capable of future processing.

The main aim of this study is to improve the processing capacity of the largescale ball mill. Taking a Φ × m ball mill as the research object, the reason for the low processing capacity of the ball mill was explored via process mineralogy, physicochemical analysis, workshop process investigation, and the power consumption method.
