Ball mill is a traditional milling equipment, which has strong adaptability to materials. It can grind various types of calcium carbonate raw materials to 100mesh. The ball mill has the advantages of stable product quality and large production capacity. The production capacity can reach 5-50 tons per hour. However, the ball mill has the disadvantages of high energy consumption, large floor area and complex operation. The unit energy consumption is about 60-70 kWh/ton, which is higher than that of Raymond mill and vertical roller mill.
Vertical roller mill is a new type of efficient milling equipment, which is gradually replacing Raymond mill and ball mill in large-scale calcium carbonate milling projects. The vertical roller mill adopts the working principle of roller pressing and grinding, which can complete the processes of crushing, grinding, grading and conveying in one step. It has the advantages of high production efficiency, low energy consumption, small floor area and good environmental protection performance. When milling calcium carbonate to 100mesh, the vertical roller mill can achieve a production capacity of 10-100 tons per hour, and the unit energy consumption is only 20-30 kWh/ton, which is 50% lower than that of Raymond mill and ball mill. At the same time, the vertical roller mill adopts a closed-loop production process, which can effectively control the dust emission, meeting the national environmental protection standards.
100mesh calcium carbonate powder has a wide range of applications in the plastic industry. It can be added to polyethylene, polypropylene, PVC and other plastics as a filler. Adding 100mesh calcium carbonate powder to plastics can reduce the amount of resin, reduce the production cost, and improve the rigidity, heat resistance and dimensional stability of plastics. For example, in the production of PVC pipes, adding 100mesh calcium carbonate powder can improve the impact strength and pressure resistance of the pipes; in the production of plastic films, adding 100mesh calcium carbonate powder can improve the transparency and toughness of the films.
To sum up, for enterprises engaged in calcium carbonate milling, the selection of appropriate milling equipment is crucial. For large-scale production enterprises, vertical roller mill is the best choice, which can improve production efficiency and reduce energy consumption; for small and medium-sized enterprises, Raymond mill is a more suitable choice due to its low investment cost. With the continuous development of the plastic industry, the demand for 100mesh calcium carbonate powder will continue to increase, and the milling equipment will also develop in the direction of high efficiency, energy saving and intelligence.
