Ⅰ. Introduction of steel ball mill

Steel ball coal mill is the main equipment of coal powder preparation system in thermal power station. At the same time, it is also suitable for pulverizing systems such as cement industry, metallurgical industry, chemical industry, sugar industry, etc. It is widely used for crushing coal of various hardness. Its function is to dry, crush and grind coal of a certain size into pulverized coal for boiler combustion. Steel ball coal mills are widely used by thermal power plants at home and abroad. According to statistics, steel ball coal mills account for more than 60% of all types of coal mills in domestic power plants.

Coal mill is a kind of ball mill. Introduction of steel ball coal mill Hard coal.

Ⅱ. Working principle of steel ball coal mill

Coal mill is a machine for crushing and grinding coal into pulverized coal, and it is an important auxiliary equipment for pulverized coal furnace. The coal grinding process is the process in which coal is broken up and its surface area is continuously increased. Coal is ground into pulverized coal in a coal mill, mainly by crushing, crushing and pulverizing. Coal mills can be divided into low-speed coal mills, medium-speed coal mills and high-speed coal mills according to the rotational speed of the coal-grinding working parts.

Ⅲ. Steel ball coal mill use

Coal mills/coal mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics and other production industries to dry various ores and other grindable materials. or wet grinding.

Ⅳ. The technical characteristics of the mill are:

(1) The transmission forms used by the drum mill include edge leaflet, center drive, multi-point meshing edge drive, etc.; the drive forms include asynchronous motor + reducer + pinion + large gear and synchronous motor + air clutch + pinion + large gear;

(2) Generally, the support method of static and dynamic pressure bearings at both ends is adopted, and a fully enclosed self-aligning 1200 line contact 'rocker type' bearing is used. Full static pressure support;

(3) The large open gear is designed according to AGMA standard, equipped with a sealed and reliable gear cover, and equipped with an automatic glycerin spray lubrication device;

(4) The cylinder is the key part of the mill, and a computer is used to carry out finite element analysis on it to ensure the reliability of its use;

(5) The large and medium-sized mills are equipped with slow drive devices;

(6) Large and medium-sized mills are equipped with high and low pressure lubrication stations;

(7) The control and protection system adopts PLC control.
