low-molecular-weight polymer on wet grinding of quartz, dolomite, and a copper ore. A 5-in ball mill equipped with a torque sensor for precise measurement of input energy was used for batch grinding tests. Grinding parameters were determined from size distribution data on the feed mate rial and ground product.
Research was done by the Bureau of Mines to determine the effect of a low-molecular-weight polymer on wet grinding of quartz, dolomite, and a copper ore. A 5-in ball mill equipped with a torque sensor for precise measurement of input energy was used for batch grinding tests.
Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force. In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and compression force which helps to

Apr 01, 1993 The implications of using different polymers as grinding aids in wet ball milling are also discussed. Introduction The success in beneficiating any ore depends on the extent to which the valuable minerals are liberated from the gangue during comminution. Since many remaining ores are fine-grained, it is necessary to grind these ores in larger ...
containing two grinding balls of 7 mm diameter and ground in neat conditions or in the presence of dierent polymers at a xed frequency of 25 Hz. While the amount of CBZ DH was kept xed at 200 mg, the amount of the polymer varied from 25 mg to 400 mg, while the milling time ranged from 1 to 180 min. Product samples
2-3 Grinding mill and studies A stirred ball grinding mill, manufactured by Drais werke GmbH, Germany, was employed for the grind ing tests.
