AIR SWEPT BALL MILL
The air swept ball mill is an ideal grinding machine that merges pulverizing and drying into a single. It has the characteristics of high efficiency, energy saving, and environmental protection. It is often used as the main equipment in the coal preparation system, which is capable to grind coal of various hardness (the fineness of pulverized coal can reach 85% and the moisture content is less than 2%). Besides, it is also suitable for fly ash, cinder, gangue, and other raw materials grinding system in the cement industry, metallurgy industry, chemical industry, fertilizer industry, etc. Because of its wide application in coal grinding, it is also called an air swept coal mill or coal mill.
As a professional ball mill manufacturer in China, AGICO offers different types of ball mill grinders with competitive prices and attentive service. The air swept ball mill is one of our hot-sale products. Due to its reasonable structure, high grinding efficiency, and low power consumption, the air swept ball mill is an ideal choice for the preparation of pulverized coal and other mineral powder.

HIGHLIGHTS OF AIR SWEPT BALL MILL
AIR SWEPT BALL MILL WORKING PRINCIPLE
The air swept ball mill mainly consists of the main bearing, ball mill cylinder, feeding system, discharge device, transmission device, high-voltage start apparatus, and lubrication system.
The feeding device first feeds raw materials into the inlet chute of the ball mill. Then raw materials enter the drying chamber through a quill shaft, dried by the hot air with a temperature of about 300 ℃. After drying, they continue to get into a grinding chamber that contains a certain number of grinding mediums. Due to the continual rotation of the cylinder, the grinding mediums are brought to a certain height by the liner installed on the cylinder. When they fall, they use the impact energy and friction force to complete the grinding process on raw materials. While the raw material is pulverized, the ground fine powder is sucked out of the mill together with the used hot air by a specially designed fan through the discharge device. After that, they pass through a separator to separate substandard coarse powder and send it back to the ball mill for regrinding.
