Several technical matters that need to be paid attention to in glass Raymond machine

Several technical matters that need to be paid attention to in the glass Raymond machine> First of all, the grinding roller gap is adjusted before starting the Raymond machine. Use a ruler to check the grinding roller gap. After starting the machine, the grinding roller gap is determined by the grinding condition of the ground material. Adjust the scale on the handwheel as a reference. In addition, the Raymond machine adjusts the pins fixed on the wall panels on both sides to keep the feeding valve and the feeding roller parallel with a certain gap. Scraper broom adjustment When adjusting the scraper broom, the grinding roller should be used as the benchmark. In order to reduce scraper wear, the gravity rod must be moved to the scraper as much as possible. The grinding roller is the main component of the mill. The grinding roller rotates at a high speed during grinding and bears great pressure. There should be grinding teeth on the surface of the grinding roller to peel off the endosperm on the bran and make it meet the process and technical requirements.
> The surface of the grinding roller should not be concave and convex, and the grinding teeth should be free of burrs, fractures and intermediate collapse. The top of the grinding gear should leave a certain tooth top plane as required, and the drawing tip should have a certain degree of curvature. The grinding angle, slope, and number of teeth for wire drawing must meet the process and technical requirements. When pulling the roller, the wire drawing machine must not have jumps or inconsistent speed during operation. The oil pump and gear of the wire drawing machine are worn and should be repaired in time.

The electronic sensor system of the vertical mill
makes the feeding door automatically open, the feeding roller rotates to feed the material, and the grinding roller enters the automatic loosening and closing program to adjust the tightness of the grinding roller. To achieve grinding effect requirements. The selection of the number of teeth of the grinding roller is determined based on the particle size of the grinding material, material properties and crushing degree requirements. The smaller the number of teeth, the larger the distance between the grinding teeth, and the tooth depth are suitable for grinding materials with large particles. As the number of teeth increases, the tooth height decreases, and the grinding teeth are prone to wear, which has a close relationship with output and quality. Due to the requirements of grinding, the two inclined surfaces of the grinding teeth are planed into an asymmetric shape to control the degree of grinding. The angle between the wide surface and the blunt surface and the center of the grinding roller to the tooth top radius is called a pure angle. The sharp angle plus the pure angle is the tooth angle. It affects the power consumption, the degree of material grinding, the quantity and quality of intermediate products and the wear resistance of the grinding teeth.
