Calcium carbonate is a common substance found in rocks, soil and oceans. It is usually used as an industrial raw material. Calcium carbonate has a wide range of uses, but must be processed to different fineness before further use. The dry production process of heavy calcium carbonate: First, hand-selected calcite, limestone, chalk and shells from quarries to remove gangue; then crushing limestone with crusher and grinding limestone with Raymond (pendulum) mill to achieve the required fineness of products. Then classified by classifier, the powder which particle size doesn't meet the requirements will be sent back to grinding mill while the powder which meets the particle size requirements will be transported to storage bin through pipes..
Calcium carbonate is a major component of shells, pearls, corals and other marine organisms. It can also be found in plants and animals. Calcium carbonate is used in paper making, food supplements and pharmaceuticals as a filler for plastics and rubber products such as tires; it is also added to ceramics, paints and cosmetics.
The dry production process of heavy calcium carbonate:
Calcium carbonate is a mineral containing calcium, carbon and oxygen. It is an important raw material in many industries and widely used in the food industry, chemical industry and pharmaceutical industry.
In order to remove the gangue from the produced calcite or limestone, hand-selected calcite or limestone must be crushed firstly, then crushed calcite or limestone will be ground again with Raymond (pendulum) mill to achieve the required fineness of products.
Then, classify by classifier, the powder which particle size doesn't meet the requirements will be sent back to grinding mill while the powder which meets the particle size requirements will be transported to storage bin through pipes.
The classification of calcium carbonate powder according to its fineness is very important for its application in many fields. In this case, if too much calcium carbonate is classified into fine particles, it may cause problems such as agglomeration of fine particles during transportation and storage; if too little calcium carbonate is classified into fine particles, it may affect product quality. Therefore, you need to choose a suitable type of classifier and control its diameter so as to achieve optimal coarse-fining conditions in order to improve production efficiency and reduce energy consumption at low cost.
The wet production method is used for water content of 20%~30% and water content of 30%~40%. There are two kinds of dry production methods: dry grinding and dry grinding & amp; wet pulverization.
Dry grinding: the material is ground into fine powder by friction between high-speed steel balls, which is a process that can be carried out under normal atmospheric pressure. The main equipment includes ball mill, classifier and cyclone separator.
Dry grinding & amp; wet pulverization: the material is ground into fine powder by friction between high-speed steel balls, then crushed in a jet mill or jet cutter machine with a very low particle size requirement for further processing. The main equipment includes jet mills (jet mills) or jet cutters (jet cutters)
The dry grinding process is the most commonly used way to produce calcium carbonate. The ore material is ground in a certain degree of fineness by a certain mill, and then directly sent to the drying machine for drying operation.
When choosing a grinding mill, it is necessary to consider the moisture content of mineral materials. Wet grinding means that when the mineral material is ground in a certain degree of fineness by a certain mill, it is mixed with water into slurry containing certain amount of solid material and then sent into the next operation. It can also be added after drying according to actual situation.
The wet method is used for water content of 20%~30% and water content of 30%~40%.
Clirik is a professional calcium carbonate grinding mill supplier in China. We have many years of experience in calcium carbonate grinding mill, and we can provide you with high quality calcium carbonate grinding mill and other products at a low price.
We offer two kinds of calcium carbonate grinding mills: ball mill and roll mill.
The ball mill uses the centrifugal force to crush the materials, which are then ground into powder with the aid of abrasive materials such as sand, metal balls or glass beads. The roll grinder uses friction between material particles and rolls to produce fine powder particles.
In terms of structure, there are two types: horizontal type and vertical type. When choosing a suitable type for your production needs, first consider how big your operations are now or will be in the future; whether they're domestic or international; what kinds of raw materials they use; what kinds of finished products they make; whether they need large amounts of power supply or not...then choose according to these factors!
