As the name implies, fine powder is a fine powder material with a high mesh number. This type of material has the characteristics of high mesh number, easy to spill, light specific gravity, and easy to block the net. Therefore, it is necessary to pay attention to the production of fine powder vibrating screens. which ones? The following points are sorted out for reference.
1. Pay attention to dust spillage
Due to the light specific gravity of some fine powders, there will be problems of dust spillage during production, and the danger of dust spillage is known to everyone. If the dust density reaches a certain concentration in a certain range, it will cause an explosion! Even if the dust concentration does not reach the explosion point, it will cause hygienic problems in the production environment and the health of employees! Therefore, in the screening process of fine powder, the equipment needs to be sealed. If conditions permit, dust-free feeding stations and vacuum feeding machines can be used to seamlessly connect from feeding to finished products to achieve clean and safe production effects.
2. Pay attention to the broken screen
The production of fine powder usually requires high precision, and the screen is the component that carries the material. During the long-term operation of the equipment, due to the heavy impact and tension of the material, the screen will be loose and damaged. Once the screen is loose or damaged, the screening accuracy will be insufficient and the product effect will be affected.
3. Protection of vibration motor
The motor is the power source of the vibrating screen equipment, and the motor used in the fine powder vibrating screen needs to be dust-proof and explosion-proof, which is related to the first precaution.
