Instantly lubricate the friction surface to ensure the normal operation of the biomass grinder and improve the service life. The lubricating grease used in the grinder should be confirmed according to the application standards, temperature and other conditions of the facility. Generally, calcium-based, calcium-based or calcium-based can be used Sodium-based lubrication. When adding grease, the grease in the ball bearing box accounts for 50-70% of its volume. It needs to be replaced every 3 months. When changing the oil, please use clean fuel or gasoline to clean the raceways of the ball bearings. .Before the operation of the crusher, the toggle plate and the contact point of the toggle plate must be filled with vegetable oil.
Dust removal method of biomass grinder:
1. Force dust removal: It can remove coarse and fine particles of about 100 μm, and is used for coarse dust removal and preparatory treatment of other fine dust. The actual operation method is to introduce dust-laden air into a large space force reduction pool to reduce the air pressure, and Apply force to lower fine particles and separate them from the air.
2. Centrifugal dust removal: The inertial force generated by the rotating activity of the air (hundreds to thousands of times greater than the force of fine particles) is used to reduce the solid particles along the peripheral wall. The facility used is a dust removal equipment, usually the inlet speed is 10 -20m\/s, the small particle size that can be captured is 5μm or smaller.
3. Inertial dust removal: It is more suitable for the separation of fine particles of about 5 μm and air. During the period of the fixed partition, the smoke and dust will impact the partition of the inertial dust removal equipment, and due to the effect of inertia, the fine particles will be captured .To prevent transmission during collision, high flow velocities cannot be applied.
4. Cleaning and dust removal: The air is brought into contact with the spray water to capture the solid particles here. The common spray dust removal tower of the crusher introduces air from the bottom, and the water is sprayed into mist from the top to carry out counter-current cleaning and dust removal.
5. Electrostatic precipitator: The solid particles in the air are charged, so that they are attracted to oppositely charged metal electrodes to achieve the purpose of dust removal. The dust collector releases tens of thousands of volts of DC voltage between the metal discharge metal electrodes, causing The air between the two electrodes is ionized. When the negatively ionized air collides with the solid particles, the solid particles are also negatively charged, attracted to the positive electrode, and lower after neutralizing the charge.
Dust will not only appear on the surface of the biomass grinder, but may also enter the interior. Due to the operation, dust will also be sucked into the interior, so pay attention to keeping it clean and tidy when removing dust.
