Limestone grinding plant is a production line to grind limestone into ground calcium carbonate powder. For limestone is mainly made up of calcium carbonate, it is often used as a basis for grinding calcium carbonate. Limestone grinding plant often uses calcium carbonate grinding mills with air classifier to grind calcium carbonate powder. Daswell machinery offers tailored turnkey solutions for limestone grinding plant, including plant designing and consultancy, providing complete set of machinery, all-around after-market services and so on. With rich experience and professional knowledge, Daswell can deliver the successful limestone grinding plant projects according to your needs. Please contact us to get free solutions.

Limestone Grinding Plant Machine
A limestone grinding plant consist of a complete set of machines. For example, there are crushers to crush the limestone to required sizes to feed into limestone grinding mill. Of course, you can also bought required sizes feed limestone from others. Besides, there will be feeding devices and conveying devices. The feeding devices can screen the feed limestone and reject the coarse ones. For the conveying system, it will convey the limestone to next phases of the limestone grinding plant. The core equipment for limestone grinding plant is the limestone grinding mill and classifier. The limestone grinding machine can be ball mill, wet grinding mill and so on. Paired with limestone grinding mill, the classifier can further cut the calcium carbonate powder from the grinding mill. As a result, the limestone grinding plant can produce different sizes of fine and ultra fine calcium carbonate powder for different uses. Since during the grinding process there will have dust, dust collectors are needed. What’s more, there are also silos to store raw material and final product.
Limestone Grinding Mill
Limestone grinding mill, together with air classifier, is the core equipment of limestone production plant. According to the ways to grinding calcium carbonate, there are dry grinding and wet grinding. Dry grinding of calcium carbonate means to grind required sizes of limestone in the mills. While the wet grinding refers to grind slurry form of limestone in the calcium carbonate grinding mill. Accordingly, there are two kinds of grinders: dry grinding mills, such as limestone grinding ball mill, vertical mill, roller mill, etc.; wet grinding mill, such as wet grinding vertical mill. The limestone grinding mill will grind the feed limestone in closed chambers. Since these grinders have different media balls, construction structures and so on, they can produce different optimum fineness powder. And combined air classifier, these limestone grinding mill can produced desired fineness of calcium carbonate. Daswell can offer you turnkey solutions for limestone grinding plant to meet customer’s needs.
Limestone Grinding Process
After have an understanding of the limestone grinding plant machine, we will come to the limestone grinding process. Firstly, the great slumps of limestone will be crushed by primary and even secondary crushers to required sizes to be fed into the grinding mill. Then the feed limestone will be transferred to raw material silo through bucket elevator. From the raw material silo, the feed limestone will go into the limestone grinding mill with required amount through the feeding device. In the limestone grinding machine, the feed limestone will be ground and impacted by the ball media in the working grinding mill. According to the needs of desired fineness calcium carbonate powder, the limestone grinding mill will be set to operate for respective period of time. After this, the partially ground calcium carbonate will be blown into air classifier. In the classifier, with rapid turning of wheel, the partially ground calcium carbonate will be further cut into more fine powder. While at the same time, the coarse powder will be rejected and be returned to limestone grinding mill for second time grinding with raw material. The fine calcium carbonate powder then will be transferred to product silo through bucket elevator. And there the final ground calcium carbonate will be packed automatically or manually. In Daswell, the whole limestone grinding process can be controlled by PLC system. As a result, few operators are needed and they can monitor the whole process and make adjustment quickly if there is malfunction.
