The importance of vertical roller mill in limestone grinding Limestone is one of the ore. It has a long history of mining. It 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 being ground, high-quality limestone is widely used in the manufacture of power plant desulfurizers, concrete admixtures, paper, rubber and other products. In recent years, in the field of limestone grinding, the advantages of large capacity, high operating rate, energy saving and environmental protection of the vertical roller mill are becoming more and more obvious, and limestone vertical mill is favored by the industry. CHAENG is a large-scale building materials and equipment manufacturer with a history of 60 years. In recent years, the limestone vertical mill developed and produced by CHAENG has performed well since it was put into the market. Its advantages are mainly reflected in the following points: 1. Adopting international advanced grinding technology, the equipment runs smoothly, the failure rate is low, and the production efficiency is high; 2. Low energy consumption, less than 30 degrees of electricity consumption per ton of stone powder; 3. Large capacity, single-machine output an annual of 300,000 to 1 million tons;

4. Dust emission ≤10mg/Nm3, in line with environmental protection requirements; 5. With composite separator, the fineness of the product can be adjusted freely to meet the needs of customers producing different products.
