Ore Grinding Mill Large Capacity Air Swept Coal Mill 350 Celsius Degrees
1. Product description of Ore Grinding Mill Air Swept Coal Mill
(1) Luo mine air swept mill | air swept coal mill specifications:
φ4×8 3.5m = inner diameter of cylinder × effective length of cylinder drying chamber length.
(2) Development process of wind swept coal mill
From the past φ2.2m, φ2.8m, φ3m, φ3.2m and so on development to the present φ3.8m, φ4m and so on. The equipment capacity ranges from 500T/D, 700T /d, 1000T /d, 2500T/D, 5000T /d, and 6000T /d
2. Working principle of air sweep coal mill of Ore Grinding Mil:
The raw coal is fed into the drying bin of the mill by the sluice of the feeding device. The hot air with a temperature of about 350℃ also enters the mill through the air inlet pipe to dry the raw coal. The dried coal goes into the grinding bin through the partition plate and is crushed under the impact and grinding of the abrasive body (steel ball). At the same time, the gas formed by the special exhaust fan will bring the pulverized coal out of the mill through the discharge device.
