Crushing Mineral Processing

In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to …

Improved bonding properties of rectorite clay slurry after wet/dry grinding

The initial rectorite clay slurry binder has a large particle size (5.809 μm of D50 in Table 4), and the wet and dry grinding processing decreases D50 to 5.548 and 4.749 μm, respectively. The dry grinding achieves a better refinement than wet grinding because the buffering of the liquid can weaken the mechanical action force, and the …
