In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes. Fine coal processing and coarse coal processing use similar operations and equipment to

Dec 26, 2015 In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Abstract. A sieve method of analysis for determining the particle size of crushed bituminous coal is described. The method is applicable to coal less than 1/sup 1///sub 2/ in. (38.1 mm) in size. Square-hole sieves of the following sizes are used: 3.35 mm, 4.75 mm, 6.7 mm, 9.5 mm, 13.2 mm. 19.0 mm, and 26.5 mm. Detailed instructions are given ...

Most of the coal mined in the United States is transported to a power plant, crushed to a very small particle size, and burned. Heat from the burning coal is used to produce steam, which turns a generator to produce electricity. Most of the electricity consumed in the United States is made by burning coal.
