It is understood that the vertical hammer mill has a rectangular structure. This type of plate hammer is fixed on the rotor with bolts, requiring a firm installation, easy replacement, and adjustable use of the plate hammer after wear. So it can be used in chemical rotary kiln. The crusher body is divided into upper and lower parts. It is welded with iron plate and steel. The inner wall of the machine body is equipped with a lining plate made of steel plate. However, the oxygen-containing chlorine-containing functional group around the skeleton shows stronger hydrophilicity, and the higher its content and degree of oxidation, the lower the surface hydrophobicity of the coal.
Therefore, the nut rotates or reverses. This type of safety device is simple but has poor reliability. Nowadays, most of the current overload protection devices are used. This is because the productivity of the lattice type ball mill is about 20 to 30% higher than that of the overflow ball mill of the same specification. The front, rear, left, and right sides of the body are provided with small doors for easy access and replacement of wear parts. There are many methyl and methylene aliphatic branches around the fused ring backbone, which show high hydrophobicity, while the fused aromatic ring backbone and its surrounding sulfur-containing branches also have poor hydrophobicity.
The relevant person based on the molecular model of coal has affirmed from the theoretical research that the basic principle of this hypothesis is correct. As described in the previous section, the structural unit of coal is composed of multi-layered aromatic fused ring skeletons. The grid-discharging end of the lattice-type ball mill is equipped with grid plates. The whole plant is equipped with grinding equipment, and the two-stage grinding sometimes uses the same specification. . So it can be used as a copper selection device. The hydraulic gyratory crusher is actually a rough single-cylinder hydraulic cone crusher. It is used for coarse crushing, but it is also useful for crushing in the second segment.
