Air Swept Coal Mill Wind-Swept Coal Mill OF Ore Grinding Mill
1. Working principle of wind-swept coal grinding of ore grinding mill
The raw coal is fed into the drying bin of the mill by the slip of the feeding device. The hot air with the temperature of about 350℃ also enters the mill through the air inlet pipe to dry the raw coal. After drying, the coal enters the grinding bin through the bin board and 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 takes the pulverized coal out of the mill through the discharging device.
2. Product description of wind-swept coal mill of ore grinding mill
(1) Air swept mill | air swept coal mill specifications:
φ4×8 3.5m = cylinder diameter × cylinder effective length drying bin length.
(2) Development process of wind-swept coal mill
From the past φ2.2m, φ2.8m, φ3m, φ3.2m, etc., the development of the current φ3.8m, φ4m, etc. Equipment capacity from 500T /d, 700T/D, 1000T /d, 2500T/D, 5000T /d, 6000T /d.
3. The wind sweep | wind swept coal grinding technology features are:
(1) The transmission forms of drum mill are edge leaflet, center transmission, multi-point meshing edge transmission and other transmission types; Drive form of induction motor + reducer + pinion + big gear and synchronous motor + air clutch + pinion + big gear;
(2) Generally, the support mode of two-terminal static and dynamic pressure bearing is adopted, and the fully enclosed self-aligning 1200 line contact 'rocker type' bearing is adopted. The static and dynamic pressure support mode of single sliding shoe, double sliding shoe or full static pressure support can also be adopted.
(3) Large open gear adopts standard design, equipped with a reliable sealing gear cover, and equipped with automatic glycerine spray lubrication device;
(4) The cylinder is a key part of the mill, and the finite element analysis is carried out on it by computer to ensure its reliability;
(5) large and medium mills are equipped with slow driving device;
(6) large and medium mills are equipped with high and low pressure lubrication stations;
(7) Control and protection system adopts PLC control.
