Raw Mill

Raw Mill

Raw mill material is crushed by the crusher and the ingredients, a key equipment for grinding again. Raw mill is widely used in cement, silicate products, new building materials, refractory material, and the glass ceramic production industry, various ores and other materials may be grinding of grinding. Our company through long-term exploration in design, production process and summarizes, has formed the different specifications, satisfy different functional requirements, a variety of materials series products. Especially more prominent in slag, cement and other materials grinding. The company can also according to different materials, the process of discharging fineness, and many special requirements for design.

Detailed introduction

  • (1) the common raw mill
  • (2) air swept mill
  • (3) tail discharging mill
  • (4) in discharging mill.
  • Common raw material mill for grinding production system for small scale; wind swept raw material dilly short and thick, the feed inlet and outlet, reduce ventilation resistance, increase the effective volume, easy to discharge, improving mill output. Tail discharge lifting raw mill into a drying bin to bin end grinding by mechanical method of unloading material grinding, pulverized material hoist into the separator, coarse material and then returned to the mill to grinding.

The working principle of grinding material

The barrel was driving device drives the rotary polishing body, because the inertial centrifugal force, attached to the inner wall of the lining plate of the drum with rotary, was taken to a certain height, borrow gravity free fall, at this time will be simplified in the grinding body material break, circular motion and grinding body rise, the drop in rotary inside the mill, to produce sliding and rolling, resulting in the grinding body, lining plate and grinding effect occurs between the ground material material.
