3 Incredible Flows to Win Calcite Processing (Without Failing)
Calcite is a widely distributed Crusher (CaCO?) mineral with various crystal shapes and is the main mineral of limestone, marble, and stalactite.
The construction, paper, paint, coating, and plastics industries are all in high demand for calcite products. So how is calcite processed? What equipment is needed for processing?
Calcite crushing process
There are three main technologies in calcite processing: crushing, sand making, and milling, and crushing is the primary stage. Calcite has a Mohs hardness of 3. It is easily broken, often breaking into small square pieces along its cleavage.
1. Process flow of calcite crushing
Primary coarse crushing: Calcite smaller than 400mm is evenly sent to the jaw crusher by Crusher for coarse crushing.
Secondary fine crushing: The coarsely crushed calcite is sent to the impact crusher or cone crusher by Crusher for fine crushing. The obtained calcite particle size can reach 5-50 mm.
Screening and classification: The finely crushed calcite is then sent to Crusher for screening, and several calcites with different sizes and specifications are separated.
2. Which crusher is suitable for calcite?
There are various types of crushers. Common calcite crushers include the jaw crusher, cone crusher, impact crusher, etc.
A. Crusher
As the first process of calcite crushing, the jaw crusher is generally selected first. Large crushing ratio, simple structure, reliable operation, simple maintenance, and low operation cost. However, the jaw plate is easy to wear and the machine is noisy.
B. Crusher
In the fine calcite crushing stage, the machine has the advantages of good particle shape, good sealing performance, less working dust, and low noise.
C. Crusher
It is often used to crush brittle materials below medium hard and is suitable for calcite crushing. The crushing ratio is large, and the size of the discharge particle size can be adjusted. But the plate hammer and the impact plate wear rapidly and have large dust pollution.
The calcite crushing process is the basic flow. Then the calcite can be further processed by sand-making and grinding to obtain greater benefits.
Calcite sand-making process
In addition to Crusher, marble, Crusher, and Crusher, calcite is also the main raw material of machine-made sand. It is an important way to relieve the tight supply of sand and gravel.
1. Process flow of calcite sand-making
Shaping: The crushed calcite can be sent to the sand-making machine for particle shaping, and the sand and gravel with the required particle size are discharged. The remaining materials are shaped again, forming a closed-circuit circulation mode.
Sand washing: The calcite sand that meets the specifications is transported to Crusher for cleaning, and then transported to the finished sand pile by the finished product conveyor.
2. Which sand-making machine is suitable for Calcite?
The sand-making machine is the core equipment of the whole calcite sand-making production line. Common machines include the impact sand-making machine, hammer sand-making machine, mobile sand-making machine, etc.
A. Crusher
There are many machine models, mainly HVI, VSI, and HX series. The overall production capacity is increased by 30%. It is used to process calcite, and the finished product has good particle size, small floor area, energy-saving, and environmental protection.
B. Crusher
Hammer sand making machine, also known as hammer crusher, takes into account both calcite crushing and sand making, forming at one time. The process is simple, and the investment cost is low. The maintenance of parts is simple, but the production scale is limited.
C. Crusher
It integrates feeding, sand making, screening, and other devices into a calcite production line. The integrated fuselage can adapt to different production environments, saving transportation costs and time.
Calcite grinding process
Calcite belongs to the type of ore that is easy to grind. Calcite grinding powder generally requires the fineness of the finished product to be small.
1. Process flow of calcite grinding
Grinding: The crushed calcite (¡Ü30mm) is lifted to the silo by Crusher and sent to the grinding chamber of the mill for grinding. Under the action of the grinding roller and ring, the material is crushed.
Grading: The milled powder is classified by the powder separator. The unqualified powder is classified by the powder separator and then returned to the main engine for re-grinding.
Collecting: The calcite powder that meets the fineness flows into the cyclone collector with the wind. After collection, it is discharged through the powder discharge pipe to be the finished product.
2. Which mill is suitable for calcite?
The mill is the key machine in the calcite grinding plant. Common calcite grinder includes ball mill, Raymond mill, ultra-fine mill, etc.
A. Crusher
If grinding 35-200 mesh calcite coarse powder, use a ball mill. The particle size of the ground product is coarse and the output is large. However, the ball mill is a horizontal structure, covering a large area, and the overall investment is greater than the Raymond mill.
B. Crusher
If grinding 80-325 mesh calcite fine powder, use a Raymond mill. The equipment has a simple structure, advanced technology, low consumption, and environmental protection. It is deeply welcomed by the market.
C. Crusher
If grinding 60-1000 mesh calcite super fine powder, use a superfine mill. The mill has comprehensive crushing performance such as rolling, grinding, impact, etc. It is an excellent equipment in the fine powder market.
Calcite processing plant
Calcite is an important raw material for calcium carbonate and its further processed products. Calcium carbonate is widely used because of its white color, low hardness, high chemical purity, and low price. After calcite processing, products have a large application market in the construction industry, sand and gravel plants, infrastructure, road construction, and other departments.
