ANNUAL TECHNICAL REPORT

fractions by sieving. The feed coal charged into the reactor had a average particle diameter of 7-8.2 mm (7000-8200 microns). Runs at 1300 psia and 400C yielded discrete fractured coal particles, the majority of which were in the 38-605 micron range. More material was present in the smaller particle size range i.e. 38-250 microns at 400C than ...

How Does the Rock crusher and Mineral sizers Work

Crushers, grinding mills, and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into two basic types, crushers, and grinders. Industrial crushers are the first level of size reducer; further granularization occurs in grinding mills or pulverizers.

For a jaw crusher the thickness of the largest particle should not normally exceed 80–85% of the gape. Assuming in this case the largest particle to be crushed is 85% of the gape, then the gape of the crusher should be = 45.7/0.85 = 53.6 cm and for a shape factor of 1.7, the width should be = 45.7 × 1.7 = 78 cm.

COKING COAL BENEFICIATION | SciTech Connect

 · The first step of Beneficiation is to crush or grind the coal to liberate the coaly matter from ashy matter which can theoretically yield complete liberation. In the case of intergrown texture, finer grinding up to a few micron size is necessary for complete liberation whereas for free dirt ordinary crushing is sufficient (Kumar, D., 1982).
