A laboratory air classifying impact mill was used for the dry grinding, and a stirred ball mill was used for the wet grinding. Products of as near the same size distribution as possible were prepared by each method, i.e., nominal minus 27 micrometers with a mean particle size of 10 to 12 ..mu..m.
Batch Ball Mill Grinding. Capacities and efficiencies in wet and dry ball milling at different speeds and ore charges have been discussed in the foregoing pages. The results are summarized in table 16, which shows that in both capacity and efficiency grinding was at its best with small ore charges and high speed.
Ball Mill. SBM ball mill is one of the new high efficient grinding machine,which is widely used in the in various types of stone grinding plant, ore benefication, electricity, cement and chemical industries.This new type ball mill with high comminution ratio, it can carry out dry or wet pulverizing and can meet demand for sustainable large scale production.
A ball mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.
