of overflow-discharge mills but not to the same extent in grate-discharge mills. This pool is situated more or less symmetrically with respect to the axis of the mill and therefore does not draw significant power. Austin recommends K = 10.6 for overflow semi-autogenous mills. A value of K = 9.32 makes Austin's formula agree with Morrell's data
The present invention relates generally to a process for removing dissolved or colloidal silica from a pregnant leach solution ("PLS"). More particularly, an exemplary embodiment of the present invention relates to a process which mixes PLS with an acid source, preferably lean electrolyte, to induce formation of colloidal silica that can then be collected and removed.

Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit. Grate discharge mills are used when the grinding energy shall be concentrated to the coarse particles without production of slimes.
Micro-Silica was ground in ball mill using iron balls of 15 mm diameter and the sizes of the ground samples were checked after 4, 6 and 8 h of grinding by Particle Size Analyzer (PSA). Concrete specimens containing ground and unground micro-silica were cast in the laboratory and tested for compressive and tensile strength s at different ages of ...
Vibration Mill is mainly for fine and ultrafine grinding. Wear resistant liners are installed inside the cylinder body of the mill. The material of the liners can be wear resistant steel, ceramic or polymer material. Our mills have successfully adopted for grinding silica, quartz, talc, zirconia and kaolin. 1.
