Grinding of high hardness materials by Calcium Grinding Mill

The choice of Calcium Grinding Mill material selection is based on the nature of the dust. This depends on the flammability and chargeability of the dust, the flow and friction of the dust.

Dust combustion or explosion fire sources are usually caused by friction sparks, static sparks, hot particles, etc., where the chargeability is high. This is because the chemical fiber filter material is usually easy to charge. If the dust is charged at the same time, it is easy to generate sparks. Therefore, it is suitable for flammable and easily charged dust such as pulverized coal, coke powder, alumina powder and magnesium powder. A flame retardant filter material and a conductive filter material are selected. Fiber woven filter cloth dust bag, such as PVC, PPs, P84, PTEF and other materials used in dust removal is safe, mixed with conductive fibers in the fiber, can achieve results.

When the dust flow and friction are strong, the dust filter bag will be directly worn out to reduce the service life. Among the common dusts, aluminum powder, silicon powder, coke powder, carbon powder, sintered ore powder, etc. are highly abrasive dusts. For abrasive dust, a filter with good wear resistance should be used. Dust filter materials have a variety of wear parts and forms, according to experience. The filter bag wears more at the lower part because the filter bag has a lower filter speed and a lower gas dust concentration.

When a Calcium Grinding Mill processes a material that is more abrasive, the bag of the corresponding material should be selected for the corresponding material. Chemical fiber is superior to glass fiber, expanded glass fiber is superior to general glass fiber, and fine, short and curly fiber is superior to coarse, long and smooth fiber.

Diatomaceous earth is a natural and hygienic coating additive. It has the characteristics of large porosity, strong absorption, chemical stability, wear resistance and heat resistance. It can provide excellent surface properties, increase capacity, thicken and improve the coating. Adhesion is therefore particularly popular in the architectural coatings market. Diatomaceous earth is mainly processed by Calcium Grinding Mill and can now be used as a filler in the papermaking industry, which can reduce raw materials and increase the new functions and characteristics of paper. In addition, in the pesticide industry, compound fertilizer industry, rubber Industry, plastics industry, paint and coating industry, feed industry, polishing and friction industry and other industries have also been widely used.

Wettable powder, dryland herbicide, paddy field herbicide and various biological pesticides. Advantages of diatomaceous earth: PH value neutral, non-toxic, good suspension performance, strong adsorption performance, light bulk density, oil absorption rate of 115%, fineness of 325—500 mesh, good mixing uniformity, will not block the agricultural machinery pipeline when used, can play a role in moisturizing, loosening soil, prolonging the effect of fertilizer effect in the soil, and promoting the growth effect of crops. In this industry application, there are certain fineness requirements, which need to be selected as the appropriate mill model, to meet the production needs of the manufacturer with low energy consumption and high output requirements.

Shanghai Shibang Calcium Grinding Mill, professional diatomite processing equipment, uniform particle size, and the screening rate is up to 99%. The whole machine structure is composed of main machine, analysis machine, pipeline device and blower. It can be equipped with crusher according to user needs. Breaking machine, hoist, electromagnetic vibrating feeder, electronically controlled motor, etc. After the material is pulverized to the required particle size, the material is sent to the storage hopper by the hoist, and then the material is uniformly and continuously fed into the mobile grinding machine by the vibrating feeder, and the grinding roller is outward due to the centrifugal force during the rotation. Swinging, pressing against the grinding ring, the blade shovels the material and sends it between the grinding roller and the grinding ring, which is crushed by the rolling of the grinding roller. The fine powder after grinding of the material is brought into the analysis machine for sorting with the circulating wind of the blower, and the finely coarse material falls back to the regrind, and the qualified fine powder enters the finished cyclone powder collector with the airflow, and is discharged through the powder discharging pipe. That is the finished product. In the grinding chamber, there is a certain amount of water in the material to be ground, heat is generated during grinding, water vapor evaporates, and the pipelines of the whole machine are not tightly connected, the outside air is sucked in, the circulating air pressure is increased, and the slag powder is ground in a negative pressure state. Under the work, the increased air flow is discharged into the dust collector through the residual air duct, and is purified and discharged into the atmosphere.
