Limestone powder production line is a production system that processes limestone blocks into limestone powder, usually including limestone mining, crushing of limestone raw materials, calcination of limestone, limestone milling and other components. Today, I would like to introduce a complete process flow of limestone powder making.
Limestone Grinding Case
Limestone mining: limestone mines throughout most of the regions in China, Guangxi, Yunnan and other places are most widely distributed, limestone usually need to be mined from the mine, you need to use blasting, excavation and other technologies in order to get the ore raw materials.
Limestone raw materials crushing: large limestone raw materials can not be directly milling process, the need to collect the limestone raw materials through the jaw crusher equipment for initial crushing, as well as impact crusher secondary crushing, so that it reaches the limestone production conditions suitable for the small particles of the material.
Calcination of limestone: The crushed material is transported to the lime kiln for calcination, which is heated to high temperature and decomposed into calcium oxide and carbon dioxide.
Limestone Grinding: The crushed limestone lumps are sent to the storage hopper by elevator, and then fed into the grinding chamber of the mill by feeder for grinding evenly and quantitatively. After grinding, the material is graded by the grading system, and the unqualified powder is graded by the grader and returned to the host machine for regrinding. The powder that meets the fineness is separated and collected with the airflow through the pipe into the dust collector, and the collected finished powder is sent to the finished product silo through the discharge port by the conveying device, and then uniformly packaged with the powder loading tanker or automatic baler.
It is worth mentioning that the process flow and equipment parameters of the limestone grinding production line may vary depending on the limestone production process and product needs, as well as the need to take into account the design requirements of the production line, equipment selection, production scale, process requirements, equipment performance and other factors.
Limestone powder can be used in construction industry, pharmacy, chemical industry, metallurgy, etc. Commonly used limestone grinding mills include LM Vertical Mill, LUM Ultra-fine Vertical Mill, MTW European Edition Intelligent Mill. Limestone grinding production line mainly consists of crusher, elevator, feeder and mill, limestone is processed into powder through crushing, elevating, feeding and other processes.
LM Vertical Mill is a new type of powder making equipment, adopting advanced feeding system, grinding system, powder discharge, fan and control system, using multi-layer annular grinding plate and roller grinding, the finished product particle size can be controlled below 100 mesh. Ultrafine vertical mill adopts multi-stage high-pressure centrifugal fan and screening equipment, which can grind limestone to hundreds of mesh or even thousands of ultrafine powder.
At the same time, Liming Heavy Industry would also like to suggest that you should pay attention to the low limestone hardness and high impurity content when matching limestone production line, and choose efficient screening and dust removal system to ensure stable product quality and even particle size without impurities, and also pay attention to regular maintenance to ensure long-term stable operation of the equipment.
