The direct forming tube mill is one of the important fine grinding equipment in the industrial history. It is mainly used for the grinding of finished products and raw materials in cement plants.

　　The direct forming tube mill is composed of main parts such as feeding device, discharging device, mill barrel, moving device (reducer, small transmission gear, motor, electric control).

　　1. The feeding device of the direct forming tube mill is composed of a feeding chute and a feeding screw cylinder. The feeding chute is equipped with a lining plate, which prolongs the service life of the feeding device;

　　2. The end cover and the hollow shaft are divided into two parts and assembled together. The end cover is machined from high-quality carbon steel, and the hollow shaft is cast and formed, which can ensure its safe and reliable operation.

　　3. The hollow shaft journal at the feed end of the direct forming tube mill is provided with a reserved gap, which can reduce the error caused by the expansion and contraction of the temperature difference and the installation of the cylinder, and ensure the correct meshing of the gears;

　　4. The inner lining plate of the tube mill is designed in combination, and different lining plate structures are adopted for different stages in the mill, which greatly improves the grinding efficiency;

　　5. The main bearing of the direct forming tube mill adopts sliding bearing. The sliding bearing has good strength, plasticity, polymerization, friction reduction, wear resistance, lubricity and heat transfer, and the replacement is simple and convenient, which can meet the requirements of hollow The shaft is well lubricated, and it is suitable for the working environment of low speed, heavy load and dusty tube mill.
