Gypsum Grinding Machine

Material properties affect the vibration of Gypsum Grinding Machines

The Gypsum Grinding Machine has a compact internal structure and fewer external devices, which saves a lot of space and reduces up-front investment. The Gypsum Grinding Machine also has the advantages of small dust, low noise, low environmental pollution, and wide application in milling production.

The Gypsum Grinding Machine runs smoothly under normal conditions, and the noise does not exceed 90 decibels. However, if the operation is not good, it will cause vibration, which will cause a lot of noise. For Gypsum Grinding Machines, reasonable vibration is allowed, but if the vibration is too large, it will inevitably lead to damage to some parts of the Gypsum Grinding Machine. Therefore, the Gypsum Grinding Machine must be strictly controlled during the production process. vibration.

Material friction factor: directly reflects the amount of internal friction generated when grinding various materials. It is directly related to whether the material layer can form a stable thickness of the abrasive layer, and whether the thickness of the material layer can be maintained directly affects the degree of grinding of the Gypsum Grinding Machine. The material with small friction factor will be squeezed out of the groove due to the action of extrusion, which will inevitably lead to the material layer being too thin, which will easily lead to the direct contact between the grinding disc and the grinding roller, causing the equipment to vibrate and damage the internal equipment; if the friction factor is large The material will be crushed to form a cake, which is difficult to loosen and cause grinding difficulties.

Grinding particle size of the material: The particle size of the material entering the grinding disc should match the grinding roller and the grinding disc. As the diameter of the grinding roller becomes larger, the peripheral linear velocity of the grinding roller also increases, so the frictional force generated also increases, so that the grinding roller is more easily engaged with the material, and the material to be ground is more easily crushed into a material. The layer, therefore, can appropriately increase the particle size of the material. However, when the particle size of the material is too large, the grinding roller will be subjected to a large impact, causing vibration caused by the imbalance of the three rollers; because the material particle size is too small, the material will enter the classifier along with the hot fan, and cannot be in the grinding disc. A layer of material is formed thereon so that the grinding disc and the grinding roller are in direct contact to generate vibration. In general, the particle size entering the Gypsum Grinding Machine should be about 5% of the diameter of the grinding roller.

Material moisture content: The amount of moisture in the material has a great influence on the Gypsum Grinding Machine. If the moisture content is too large, the material is not easy to dry. The wet material will be wrapped and adhered to other materials, even wrapping the grinding roller, resulting in the grinding disc. The accumulation of materials causes the grinding roller to be difficult to press, causing vibration to jump. If the moisture of the material is too small, the viscosity of the material will be too low, and the friction factor between the materials will be lowered, making it difficult to stay on the grinding disc for a long enough time to form a layer of a certain thickness, which will result in the grinding disc and the grinding roller. Rigid contact increases vibration.
