Limestone is widely distributed in China, with abundant reserves and extremely versatile resources. It is commonly used as a building material and is an important raw material for many industries. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide. It is an indispensable flux limestone in the metallurgical industry. After processing by grinding mill, such as raymond mill and ultrafine mill, limestone is widely used in paper, rubber, paint, paint, In the manufacture of pharmaceuticals, cosmetics, feed, sealing, bonding, polishing and other products. It can be also used to produce Portland cement to produce coated grade heavy calcium carbonate products for papermaking.
The common processing technology of limestone is to use a special mill to mechanically pulverize it into powder. After limestone is directly pulverized, it can produce heavy calcium carbonate, which is used in various industrial sectors according to the grinding fineness.
Limestone has a promising market for a wide range of products. However, However, because limestone is abundant in China, there is no local resource advantage. Therefore, in the face of the development of this resource, we should carefully choose the shortest process as simple as possible to achieve the market competitiveness with low cost and high quality. Generally, limestone can meet the requirements of cement raw materials after crushing and grinding.
In the process of limestone crushing and grinding are indispensable. The series of mill equipment manufactured by Guilin Hengda Mining Machinery has higher efficiency than ball mill, low power consumption, small floor space and small one-time investment. The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force, so that when the grinding roller and the grinding ring are worn to a certain thickness, the yield and fineness of the finished product are not affected. The replacement cycle of the grinding roller and the grinding ring is long, so that the shortcomings of the replacement cycle of the wearing parts of the centrifugal pulverizer are eliminated. The air-selected airflow of the mill is circulated and flowed in the fan-grinding shell-cyclone-fan, so it is less dust than the high-speed centrifugal pulverizer.
