The 200 Cross Beater Lab Mill is used for crushing coal, chemicals, spices, bricks, soil, grain, The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. Units can be supplied with hardened wear parts when crushing harder, abrasive materials.
Mesh size refers to the number of openings in one inch of screen. For example, a 4mesh screen means that there are four squares within one inch of the screen. As the mesh size increases, the particle size decreases to create a finer material. Mesh size is not a precise measurement of particle size, but it
Material with a particle size of up to 30 mm is handled by ball and rod mills; selfgrinding mills are suitable for particle sizes up to 300 mm. The particle size of the product may be less than mm. The wear of the steel balls in grinding is 13 kg per ton of ore.
The particle size distribution of milled coal depends partly on the rank of the coal, which determines its brittleness, and on the handling, crushing and milling it has undergone. Generally coal is utilised in furnaces and coking ovens at a certain size, so the crushability of the coal must be determined and its behaviour quantified.
Optimill hammer mill series. The Optimill series consists of hammer mills that can be applied for grinding of raw materials for normal to coarse structured products. Key features: Coarsegrained particles optimum particle size range; Patented closed rotor design saving up to 20% in energy consumption; Large screen area; 1,5001,800 rpm

designated as beaters. Hardgrove Index (HGI) Grindability of a coal expressed as an index showing the relative hardness of that coal compared with a standard coal of 100 grindability. Height of Drop Vertical, free fall distance from the lip of the feeding device to the inlet opening of an impactor or hammermill crusher.
Measurements of the particle size distribution at the outlets of six coalfired utility boilers showed a peak at a particle diameter near micrometer. This submicrometer mode appears to be a general feature of coal combustion that results from a volatilizationcondensation process in the boiler. At the boilers tested, the submicrometer mode contained to percent of the total fly ash
