3000 mesh high quality calcium carbonate grinding mill grinding plant

Posted: 2019-10-16

In order to meet the demand for high quality ultrafine calcium carbonate powder in the high-end market. We, Shanghai Clirik Machinery Co., Ltd., combined with years of experience in grinding machine production, based on ordinary vertical grinding, using advanced Taiwan grinding roller technology and German powder selection technology, the new CLUM ultrafine calcium carbonate grinding mill designed independently. The ultrafine vertical mill with ultrafine grinding, grading and conveying is an ultrafine milling equipment with excellent performance.

CLUM ultrafine calcium carbonate grinding mill

[Feed size]: <10mm

[Output size]: D97 less than 4 μm, D50 less than 2 μm

[Production capacity]: 5-18 tons / hour

[Application field]: Widely used in chemical, metallurgical, non-metallic minerals and other industries. (For more application areas, please click on the bottom right to contact)

[Applicable materials]: Mohs hardness below 5, density below 3.2, compressive strength below 150Mpa, non-flammable and explosive minerals, non-corrosive brittle materials granular and powdery raw materials. Such as limestone, calcite, talc, barite, dolomite and other non-metallic ores.

Process principle

The main motor drives the grinding disc to rotate through the reducer, and the wind enters the CLUM ultrafine calcium carbonate grinding mill from the air inlet. The material falls on the grinding disc through the feeding end of the screw feeder. Under the action of the centrifugal force, the material moves evenly from the grinding disc to the edge. When the grinding roller area on the grinding disc is crushed by the grinding roller, the bulk material is directly crushed, and the fine material is pressed to form a material bed for intergranular pulverization. The pulverized material continues to move toward the edge of the disc until it is carried away by the strong airflow at the wind ring, and the larger particulate material is again dropped onto the grinding disc to continue pulverization. When the material in the airflow passes through the upper separator, the rotor Under the action of the blade, the coarse particles are returned to the grinding disc for grinding. The qualified fine powder is ground together with the airflow and collected by the system's dust collector. The collected powder is the ultrafine vertical milled product. When the iron block and other impurities mixed into the material move to the edge of the grinding disc, they cannot be blown by the wind due to their own weight, and fall to the lower chamber of the mill. The scraper plate installed at the bottom of the grinding disc is scraped into the slag discharge port and discharged outside the machine. .

Product description

CLUM ultrafine calcium carbonate grinding mill is mainly composed of electric motor, reducer, grinding roller device, grinding disc device, pressing device, classifier, body and oil station.Its appearance turned out to make the one-time completion of the ultra-fine powder grinding, grading and transportation operations realistic, and its technical parameters such as process parameters, mechanical properties and finished powder quality are equivalent to Taiwan's level.

Advantages

1. Multi-head selection, no need for secondary air classification, more energy efficient and more economical

We use PLC control system and multi-head powder selection technology in this machine. This application completely solves the two problems of “high-precision and accurate cutting powder particle size and fast switching of different production requirements”. Users can precisely control the grinding pressure. Equipment operating parameters such as speed. Compared with ordinary mills, the machine's energy consumption is reduced by 30%-50%.

2. Uniquely designed grinding curve for higher yield and better quality

In order to avoid the problems of long material residence time, repeated grinding and high iron content during the grinding process of traditional mills, we have specially designed a unique roll sleeve and liner grinding curve. The design is easier to form the material layer, and the high yield obtained by one-time grinding not only greatly improves the working efficiency of the mill, but also improves the whiteness and clarity of the finished product.

3. Reversible design for easier maintenance

In the design process of the machine, we fully considered the maintenance problems that the heavy-duty grinding roller may bring, and finally developed a reversible structure. The structure is matched with the hydraulic adjustment system, and the operator can easily and quickly turn the grinding roller out of the casing for maintenance, replace the roller sleeve, the liner and other maintenance operations, thereby reducing the downtime loss.
