Ore Grinding Mill Air Swept Coal Mill
Ⅰ. Technical characteristics of air-swept coal mill(ore grinding mill)
(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 equipped with a sealed and reliable gear cover, and is equipped with an automatic glycerin spray lubricating 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.
Ⅱ. Specification and meaning of air-swept coal mill(ore grinding mill)
φ4×8+3.5m = inner diameter of cylinder×effective length of cylinder+length of drying bin
Ⅲ. Development process of air-swept coal mill(ore grinding mill)
From the past φ2.2m, φ2.8m, φ3m, φ3.2m, etc., to the present φ3.8m, φ4m, etc. Equipment capacity from 500t/d, 700t/d, 1000t/d, 2500t/d, 5000t/d, 6000t/d.
Ⅳ. Working principle of air-swept coal mill(ore grinding mill)
The raw coal is fed into the drying bin of the mill from the runner of the feeding device, and the hot air with a temperature of about 350 ℃ also enters the mill through the air inlet pipe to dry the raw coal, and the dried coal enters the grinding mill through the partition board The silo is crushed under the impact and grinding of the grinding body (steel ball). At the same time, the gas formed by the special exhaust fan will bring the pulverized coal powder out of the mill through the discharge device.
