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:
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.
3. Luo mine development and design the wind sweep | wind swept coal grinding technology features are:
(1) Cylinder mill adopts the transmission form of edge flyers, center transmission, multi-point meshing edge transmission and other transmission types; The driving form is asynchronous motor + reducer + pinion + big gear and synchronous motor + air clutch + pinion + big gear;
(2) The general use of two static and dynamic pressure bearing support mode, the use of fully enclosed self-alcolating 1200 line contact 'rocker type' bearings, can also use single sliding track, double sliding track static and dynamic pressure support or full static pressure support;
(3) Large open gear adopts American AGMA standard design, equipped with a reliable sealing gear housing, with automatic spray lubrication device glycerin;
(4) Cylinder is the key part of the mill. Finite element analysis is carried out by computer to ensure the reliability of its use.
(5) Large and medium-sized mill equipped with slow driving device;
(6) Large and medium-sized mill equipped with high and low pressure lubrication station;
(7) Control and protection system adopts PLC control.
