Rolling Coal Mills provide fine coal for efficient burning. The mills grind the coal into small uniform particles.
Analytical results showed the presence of excessive concentrations of 120 micrometer (um) Cutting/Plowing wear particles. The vast majority of these Cutting/Plowing wear particles were composed of High Carbon (~12%) steel and to a lesser extent medium alloy steel.
The high concentration of this Cutting/Plowing wear particles indicated an alignment problem. The supposition of an alignment problem was further supported by the presence of 30um Copper Alloy (including Brass &Bronze) Rolling Contact (Bearing) wear particles and 25um white non-ferrous metal Rolling Contact (Bearing) particles. This white non-ferrous metal is most likely Aluminum. However, Nickel, Chrome and Stainless Steel are also other possibilities.
Coal ball pulverizer is an efficient tool for grinding many materials into fine powder. The Coal ball pulverizer is used to grind many kinds of mine and other materials, or to select the mine, widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.
LM series vertical Coal pulverizer is the newest grinding machine, which integrates the advanced international technology and years of mill-producing experience . It is an ideal equipment that integrates crushing, drying, grinding and grading conveyor all together.
