The raw material of calcite is limestone ore which is deeply processed and ground by a pulverizer. my country is very rich in limestone mineral resources and ranks among the world's largest manufacturers of calcite. A large amount of calcite is produced every year. The mill can process calcite into powder and can be applied to other fields.
The calcite production line process can be summarized as: limestone raw ore - vibrating feeder - jaw crusher - bucket elevator - raw material silo - impact crusher - bucket elevator - impact crusher (cone crusher) - super Fine mill - bucket elevator - conveyor - clinker silo cooling, storage - finished product. Among them, the grinding process is particularly critical.
The ultra-fine pulverizer is suitable for the processing and production of calcite. It has high efficiency, low power consumption, small footprint, small one-time investment, clean operation workshop and no pollution to the environment. The fineness can be as large as 3250 meshes, which can meet all the fineness requirements of the other calcites on the market.
Calcite can be divided into: calcite for building materials, calcite for chemical industry, calcite for mold, calcite for food and calcite for casting. With the rapid development of my country's economy and the emphasis on environmental protection in recent years, desulfurization in power plants has become a necessary process for power plants, and limestone desulfurization has become the main raw material for desulfurization in power plants. Limestone minerals rely on rich natural and artificial resources for comprehensive utilization and development. The calcite industry is also the need to build a circular economy, attracting more and more investors.
The working principle of the ultrafine pulverizer:
When working, the main motor of the superfine pulverizer drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway.
The raw limestone material is crushed into small particles by the hammer crusher, and then sent to the storage bin by the elevator, and then passed through the vibrating feeder and the inclined feeding pipe, and the limestone particles are evenly sent to the upper part of the turntable. .
The limestone particles are scattered to the periphery of the circle under the action of centrifugal force, and fall into the raceway of the grinding ring. They are impacted, rolled and ground by the ring rollers. Inhaled into the machine, and brought the crushed calcite into the classifier.
The rotating impeller in the powder separator makes the coarse calcite fall back for regrinding, and the fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the lower part of the powder. The air flow of dust is purified by the pulse dust collector and discharged through the fan and the muffler.
The complete set of limestone ultrafine mill configuration includes hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-powder mill host, frequency conversion classifier, double cyclone powder collector, pulse dust removal system, high pressure fan, Air compressor, electrical control system.
