A comparative study on the effects of dry and wet

2019-9-1  Ogonowski et al. (2018) conducted an investigation to compare wet and dry grinding processes in an electromagnetic mill. They reported that for the same products, dry grinding needs 3 kW of power while the wet condition requires 1.6 kW.

Comparison of Wet and Dry Grinding in Electromagnetic Mill

Comparison of dry and wet grinding process in an electromagnetic mill is presented in this paper. The research was conducted in a batch copper ore grinding. Batch mode allows for precise parametrization and constant repetitive conditions of the experiments. The following key aspects were tested: processing time, feed size, size of the grinding media, mass of the material and graining media ...

Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
