In the manufacturing of paper, limestone powder is used as a filler. It improves the opacity, brightness, and smoothness of the paper. In the plastics industry, it can be added to plastics to enhance their stiffness, dimensional stability, and heat resistance. For example, in the production of plastic pipes for plumbing systems, the addition of limestone powder can make the pipes more resistant to deformation under pressure and temperature changes. In the rubber industry, limestone powder is used as a filler to reduce the cost of rubber products while also improving their mechanical properties such as hardness and tear resistance.
The Grinding Process in Detail & Equipment Used
Two common types of equipment for limestone grinding are the Raymond mill and the vertical mill. The Raymond mill is a classic grinding device. It has the advantage of a relatively simple structure, which makes it easy to operate and maintain. It is also relatively cost - effective, making it suitable for small - to - medium - scale production. However, it may have limitations in terms of processing capacity and energy efficiency compared to more advanced equipment.
The vertical mill, on the other hand, is a more modern and efficient option. It has a higher processing capacity and better energy - saving performance. It can handle large amounts of limestone raw materials and produce high - quality powder with a more uniform particle size distribution. In this project, considering the set processing capacity of 5 tph and the need for a stable and efficient production process, the vertical mill is more suitable. It can meet the production requirements while also reducing long - term operating costs due to its energy - saving features.
