calcium carbonate grinding mill

calcium carbonate grinding mill

Calcium carbonate is divided into two categories: heavy calcium carbonate and precipitated calcium carbonate. Due to the differences of the particle size, crystal form, the nature of interface between heavy calcium carbonate and precipitated calcium carbonate, their features are vastly different.

calcining the raw materials such as limestone to generate lime (ingredient for calcium oxide) and carbon dioxide; then adding water to digest lime to generate lime milk (ingredient for calcium hydroxide)and then passing into the carbon dioxide carbide lime milk for calcium carbonate precipitation; lastly, the calcium carbonate precipitation by dehydration, drying and crushing system to get light calcium carbonate.

in the process of producing caustic soda (NaOH), can be a by-product of light calcium carbonate. Adding lime hydrate in soda ash aqueous calcium carbonate can generate precipitation, and get the caustic soda solution at the same time, lastly the precipitation of calcium carbonate by dehydration, drying and crushing system to get light calcium carbonate.

in the process of producing soda ash, by-product light calcium carbonate can be obtained. Saturated salt water with carbon dioxide for carbonation after inhaling ammonia, then get the heavy alkali (sodium bicarbonate) precipitation and ammonium chloride solution. Light calcium carbonate production technology is mainly divided into the following steps: 1. The limestone calcination 2. quick lime digestion 3.lime water carbonated4.sedimentation and filtration 5. Drying and crushing.

Stable performance, convenient operation, low energy consumption, adjustable and controllable final size, widely used grinding materials , equipped with special dust collector, and dust emission concentration is lower than the national environmental regulations completely.

The working principle is for vertical structure, covering a small area, complete and strong set, and motor transmission device enclosed gear box, with smooth transmission. An important part of the mill adopts high-quality steel manufacturing, so it is reliable and durable. Electrical system of the mill adopts centralized control, advanced and reasonable selection, automation with high degree, vibrating feeder with small size light weight, it is easy to adjust and save electricity.

It solves the leakage phenomenon when grinding the calcium carbonate, improves the grinding efficiency, eliminates the impact on the main shaft, prolonging the service life of the roller shaft, greatly improves the precision and efficiency of selecting powder, reduces the transmission between the mill and classifier and eliminates the resonance phenomenon.

This series mills are mainly applied to the powder processing of mineral products in the metallurgy, construction material, chemical, mining, the highway construction, water conservancy and hydropower, refractory materials, and steel, etc.

The working principle is that by the shovel blade ,calcium carbonate is put to the middle of calcium grinding roller and grinding ring , under the grinding pressure of calcium carbonate is crushed into powder, then under the action of the fan ,the powder of calcium carbonate is passed to analyzer. If the powder calcium carbonate fails to achieves the required fineness by analyzer, it will return to the grinding chamber to continue to grind then through analyzer, calcium carbonate is put into whirlwind powder collector finishing separation and collection. Lastly, with industrial filter cloth isolated exhaust was put into powder at one time. They can produce powder from various non-flammable and non-explosive mineral materials with Mohs hardness below 7.0 and humidity below 6%.

Lots of industries need calcium carbonate powder as raw material, such as PVC, Electric Cable, rubber, PE, painting and paper making industries. And many industries like PVC, PE and coating has specified standards to the powder size, usually it must be finer than 1250mesh. As a result, most grinding mills, such as coarse power mill, MTM series milling machine and MTW series grinding mill, are out of action. How to produce the ultrafine calcium carbonate powder? Currently, the mainstream machine is ZENITH XZM series ultrafine grinding mill. With this mill, not only 800-1250mesh powders are available, but also 1250-2500mesh powders are getable. Whats more important is that the production cost is quite low because of its special design.

Barite and fluorite compound mineralizer is incorporated in cement production ,which has a significant effect on promoting C3S formation and activation of C3S. Cement industry mineralizing agent

in 2009, a mining company in India intended to produce calcium carbonate powder with fineness of 5-10 micron at the capacity of 1.0 TPH. After investigate, we recommended him using our XZM221 Ultrafine mill and helped him build the plant.

Case Study A mining company in India intends to produce calcium carbonate powder with fineness of 5-10 micron; Required capacity is 1.0 ton per hour. They had a Raymond mill which can not meet their desired fineness. The feeding size of the raw stone is 12"-14". They have a primary 16"10" jaw crusher. Based on customers situation, we recommended full set of XZM221 Ultrafine mill for their requirement. The mill was installed in 2009 and is running perfectly in India now.

Production Process Raw material of 12"-14" size is primarily crushed by the clients jaw crusher down to 2" and then enters our hammer crusher PC400300, after secondary crushing, it will be less than 0.4", and discharged to bucket elevator. The elevator sends the material to storage hopper, theres a vibrating feeder under the hopper, the feeder feeds material to main unit of XZM221 mill evenly and continuously. When the material being ground in the mill, the blower blows the powder to classifier, the classifier impeller is rotating at adjustable speed which is controlled from control cabinet, as per clients requirement, powder less than 10 micron will be separated by classifier, and bigger powder falls down, being reground over and over again. 10micron and less than 10micron powder then go to the cyclone collector with the air from blower and be collected in the cyclone collector. Powder will be discharged from the discharge valve to become the final products. The bag filter will clean the outgoing air to protect the environment.
