Grinding Mill 1 A twenty foot diamter ball mill rotates at a copper mining processing facility in Chile. This process breaks copper bearing ore from golf ball sized pieces into dust. Some other motors, ladders, and equipment is visible too. ball mill stock pictures, royalty free photos amp; images
Copper Mountain first feed to the SAG mill occurred in late May, 2011. The circuit began ramp up in mid June of that year, with more consistent operating run times on the SAG and Ball mills. Plant throughput in the first months was quite variable with throughput tonnage greater than 40,000 tons one day and less than 25,000 the next on some ...
The 24 x 39.5 Ball Mill The Copper Mountain ball mills are 7315 mm 24 feet in diameter and 12040 mm 39.5 feet long. They are overflow discharge ball mills with inside diameters of 7315 mm 24 feet and grinding lengths of 11887 mm 39 feet. Each Ball mill is also driven by two 8,500 horsepower ABB motors.
The ball mill is a typical material grinder machine which widely used in the mineral processing plant, ball mill performs well in different material conditions either wet type grinding or dry type, and to grind the ores to a fine size. Main ball mill components: cylinder, motor drive, grinding medium, shaft. The cylinder cavity is partial ...
Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. . The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized ba
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter . The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
