Calcite introduction

Calcite is a calcium carbonate mineral, which is more common in natural calcium carbonate. Therefore, calcite is a widely distributed mineral. Calcite has a variety of crystal shapes, and the aggregates thereof may be a cluster of crystals, or may be granular, massive, fibrous, stalactite, earthy, and the like. Strike calcite can get a lot of square pieces, hence the name calcite



Mohs hardness:3


Color:transparent, colorless or white, sometimes with variegated

Main components:(from Ca (calcium), C (carbon), O (oxygen) three elements

Calcite processing production process

First, the calcite and calcite shipped from the quarry are coarsely crushed by a crusher, and then crushed with a calcium carbonate mill to obtain fine calcite powder. At the end, the mill is graded by a classifier to meet the particle size requirements. The product is packed into the warehouse, otherwise it will be returned to the calcium carbonate grinding machine for grinding again.

The first stage: broken

The calcite bulk material is crushed by the crusher to the incoming fineness (15mm-50mm) which can enter the mill.

Second stage: milling

The crushed calcite small pieces are sent to the silo through the hoist, and then uniformly and quantitatively fed into the grinder grinding chamber through the vibrating feeder for grinding.

Fine powder processing can be selected by LM vertical roller mill, MTW European version of grinding, 5X European version of intelligent grinding;

Ultra-fine powder processing can be selected by MW ring roller micro-grinding, LUM ultra-fine vertical grinding; coarse powder processing can be selected with CM European coarse grinding

The third stage: grading

The ground material is graded by a classifier, and the unqualified powder is classified by the classifier and returned to the main machine for re-grinding.

The fourth stage: collecting powder

The fine powder conforms to the airflow and enters the dust collector through the pipeline for separation and collection. The collected finished powder is sent to the finished silo by the conveying device through the discharge port, and then uniformly packaged by the powder tanker or the automatic baler.

The main use of calcite

The main component of calcite is calcium carbonate, and its main purpose is to make heavy calcium powder. Heavy calcium powder for 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, Filling materials in textiles, feeds, adhesives, sealants, asphalt, building materials, linoleum construction products, fireproof ceilings and chemicals. It can not only reduce the product cost of various industries, but also improve the function and performance of related products, and increase the volume of the product. It is one of the widely used inorganic filler masterbatch. At the same time, calcite is also widely used in the production of light calcium powder, and is also widely used in various industrial fields.

Fineness use Equipment recommendation
Within 325 mesh Common customers are used to make putty powder, ordinary 325 mesh can be used, also used in chemical, cement and other industrial raw materials. Calcite is used as a flux in the metallurgical industry and used in the construction industry to produce cement and lime. Filling additives in foods. The addition of calcite to the glass production results in a glass that becomes translucent and is particularly suitable for use as a glass shade. MTW
400 mesh - 800 mesh Used for high quality putty powder, also used in plastics, paper, toothpaste, soap, etc.; SCM、LUM
More than 800 mesh For rubber, plastic, cable, PVC (whiteness above 94 degrees) SCM、LUM
More than 1250 mesh It can be used as raw materials for PVC, PE, paint, coating grade products, paper coating, paper coating, and ink. SCM、LUM
