First, the calcite transported from the quarry is roughly crushed with a crusher, and then crushed and ground with an ultra-fine pulverizer to obtain fine calcite powder, and then the fine calcite powder is classified with a classifier. Powders that meet the particle size requirements are packaged into storage, and those that do not meet the requirements are returned to the ultrafine mill for re-grinding.
The first stage
First use the stone crusher equipment to crush the large pieces of calcite.
The second stage
After crushing, the materials with suitable particle size are sent to the HGM series ultrafine grinding mill by the conveying equipment.
The third stage
After the material enters the ultra-fine grinding mill, it goes through the pulverization process, classification process and separation process of the pulverizing equipment to obtain the finished product.
The fourth stage
Packaging and storage of finished materials.
Required equipment
HGM series ultrafine pulverizer
Non-metallic ore ultra-fine powder grinding equipment independently developed and produced by CLIRIK. The fineness can be freely adjusted between 150-2500 mesh, the output is 0.2-45t/h, and the powder quality is good.
Advantage:
● Higher productivity, lower energy consumption
● 150-2500 mesh, fineness can be adjusted arbitrarily
● Rolling bearings in the core, no screws, safer operation of the equipment
● Pulse dust removal, high environmental protection level
● Digital processing, higher precision
● Original spare parts supply, worry-free operation
Working principle:
After the bulk material is crushed to the required particle size by the hammer crusher, it is sent to the silo by the elevator. Then it is uniformly and continuously fed into the inside of the host through the feeding equipment. The materials entering the main machine fall onto the bulk material tray on the upper part of the main machine turntable with the inclined guide tube.
When the main engine is working, dozens of grinding rollers rotate and roll in the ring. Under the action of centrifugal force, the materials are scattered to the periphery by the bulk material disc and fall into the grinding chamber, and are punched, rolled and ground by the grinding rollers in the ring.
After multi-layer grinding and grinding, the material enters the powder separator with the air flow of the fan for powder classification. Under the action of the impeller of the powder separator, the materials that do not meet the fineness requirements fall back into the grinding chamber for re-grinding, and the materials that meet the fineness requirements enter the cyclone powder collector with the airflow. The powder is separated and collected in the powder collection, and discharged from the unloading device at the bottom.
The rest of the powder enters the pulse dust collector from the upper part of the powder collector and adheres to the surface of the filter bag. The pulse valve controls the high-pressure air flow so that it is instantly sprayed into the filter bag, causing the filter bag to fluctuate violently. The adhering powder is ejected by the sudden shaking of the filter bag. The powder falling on the lower part of the dust collector is collected by the screw conveyor.
The filtered airflow is discharged into the air with the fan through the muffler. The system is an open circuit system and operates under negative pressure.
Investment prospects
Whether it is heavy calcium carbonate or light calcium carbonate, it has an extremely wide range of applications in petroleum, metal smelting, chemical synthesis, aerospace, high-temperature superconductivity, machinery manufacturing, etc., especially in high-tech fields. In particular, ultrafine heavy calcium powder, which can be used as a basic material in these industrial sectors, is also in particularly high demand.
Therefore, heavy calcium fine powder has become the upstream and raw material of most industrial manufacturing, covering almost all production and manufacturing sectors of light and heavy industries. With the continuous progress of ultrafine powder grinding technology, their application fields are constantly expanding, and they will play a greater advantage in the future.
Application field
Main uses of calcite
The main component of calcite is calcium carbonate, and its main purpose is to make heavy calcium powder. Heavy calcium fine powder is used in artificial stone, artificial floor tile, natural rubber, synthetic rubber, paint, plastic, composite new calcium plastic, cable, paper, toothpaste, cosmetics, glass, medicine, paint, ink, cable, electrical insulation, food, It is used as filler in textiles, feed, adhesives, sealants, asphalt, building materials, linoleum building supplies, fireproof ceilings and daily chemicals. It can not only reduce the cost of products in various industries, but also improve the function and performance of related products, and increase the volume of products. It is one of the most widely used inorganic filler masterbatches. At the same time, calcite is also widely used in the production of light calcium powder, and it is also widely used in various industrial fields.
