The full set of ultra-fine calcium carbonate powder production project was officially launched. CLIRIK dispatched a professional construction team to the customer site to ensure safe, efficient and high-quality construction.

ultrafine calcium carbonate project

This calcium carbonate grinding project is expected to produce 170,000 tons per year, and the main products of calcium carbonate powder are: 800 mesh, 1250 mesh, 2500 mesh. This fineness of calcium carbonate powder can be widely used in coatings, rubber, paper, plastics, paints and other fields.

CLIRIK offers a full range of ultrafine calcium carbonate production line technologies. We are committed to providing you with safe, intelligent, industrialized, high-quality, green and environmentally friendly calcium carbonate production lines.

We provide a full-process service from the initial product drawing plant design to the final after-sales installation. Escort your project with high-quality products, professional service and responsible attitude.

The most important part of this project is the development and production of two ultrafine pulverizers by CLIRIK: the HGM ultrafine mill and the CLUM ultrafine vertical mill.

The following will introduce the two machines in detail.

1. HGM Ultrafine Mill

HGM ultrafine grinding mill also named HGM micro powder ring roller mill. It can be used for calcium carbonate, limestone, calcite, marble, talc, barite, gypsum, dolomite, bentonite, mica, pyrophyllite, sepiolite, diatomite, graphite, alumite, fluorite, potassium feldspar , Phosphate rock, pigment and other more than 100 kinds of non-flammable and explosive materials with humidity less than 6% and Mohs hardness not greater than 6 are processed into ultra-fine powder. The particle size of the finished product is 325-2500 mesh (0.044-0.005mm).

Working principle of HGM grinding mill

The main engine motor drives the main shaft and the turntable to rotate through the reducer, and the turntable drives dozens of ring rollers to roll and rotate in the grinding ring raceway through the pin. The bulk material is crushed into small particles by the hammer crusher and then sent to the storage bin by the elevator.

The electromagnetic vibrating feeder evenly sends the material to the bulk material tray on the upper part of the turntable, and the material is scattered to the circle under the action of centrifugal force.

The periphery of the grinding ring falls into the raceway of the grinding ring to be punched, milled, ground and pulverized by the ring roller. After the first layer is pulverized, the material falls into the second and third layers.

The suction effect of the high-pressure centrifugal fan sucks the outside air The crushed material is brought into the classifier.

The rotating turbine in the powder concentrator makes the coarse particles fall back for regrinding, and the fine powder enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the bottom of the powder concentrator.

After purification, it is discharged through the fan and muffler.

2. CLUM Ultrafine Vertiacl Mill

CLUM Ultrafine Vertical Mill is the abbreviation of CLUM series ultra-fine powder vertical roller mill. It can be widely used in chemical, metallurgical, non-metallic ores and other industries, especially in the field of ultra-fine grinding of white non-metallic ores. Rubber, PVC, ink and other industries provide high-quality fillers and additives. It can be widely used in large-scale ultra-fine dry powder processing of non-metallic minerals such as calcite, marble, limestone, dolomite, barite, talc, kaolin, dolomite, wollastonite, gypsum, feldspar, and pyrophyllite.  

CLUM ultrafine vertical mill

It can process 400-3000 mesh high quality fine powder. Compared with the HGM grinding mill, the CLUM vertical mill has a higher subdivision content, D97 can reach 2 microns, and D50 can reach 4 microns.

Working principle of CLUM Ultrafine Vertical Mill

The grinding disc is driving by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high effiency classsifer.The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.
