Vertical Coal Mill Sale
Vertical roller mill uses hydraulically loaded vertical rollers resembling large tires to pulverize raw coal fed down onto a rotating table. As the table rotates, the raw coal is pulverized as it passes underneath the rollers.
Hot air forced through the bottom of the pulverizing chamber removes unwanted moisture and transports the pulverized coal dust up through the top of the pulverizer and out the exhaust pipes directly to the burner. The new type coal pulverizer designs are vertical roller coal mills.

Vertical Coal Mill Application
Vertical mill is widely used in cement industry, electric power, metallurgy, chemicals, and non-metallic mineral industry. It can grind coal, marble, granite, kaolin, hard coke etc. So it is also called vertical coal mill or vertical cement grinder. When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then it revolves round the vertical axis line by the milling roller hung on the star rack. With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.
