The coal sample, as received from the field, consists of 3 to 15 kg of material that first is reduced to a particle size of 2 to 4 mm (5 to 10 mesh) in a jaw crusher. This crushed material is then divided into three splits. The first split is forwarded to a laboratory for standard ultimate and proximate analyses.
It is desirable to use material which has as nearly the same metallurgical characteristics as the samples with which the standards will be included. This is usually a difficult chore. For many reasons, including the particle size at which a significant amount of the gold mineral is liberated, the sampling characteristics of even -150 mesh material may preclude the use of geologically and ...

Pulverizer Wikipedia. A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer puritch is used to pulverize coal for combustion in the steamgenerating furnaces of fossil fuel power plants
Optimized coal pulverizer performance is a prerequisite for ensuring the best furnace combustion efficacy. Here are some solutions for overcoming commonly identified combustion problems.
Holmes Coal Pulverizers are bench-type units that perform well in reducing coal or coke from No. 4 to No. 60 sieve size. Models are available with manual or auger feed. All units are constructed of painted steel and cast iron, and have one-piece balanced rotor with hard coated hammers, driven by 1hp, single phase motor with overload protection.
RPM (Machine): 2800-3500 Body material: SS. Capacity: 1200 r/h. Fineness : 100-300. Output Range : 50 - 60 Kg/Hr. Power: 4.5 - 7.5 kw
13.1.Fineness : 13.1.Fineness Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance.
