Cement is closely related to our life. The buildings we see everywhere are inseparable from cement. It has a very important position and role economic development. In order to improve the efficiency and quality of material grinding, many researchers continue to research and improve grinding mill equipment. The use of vertical roller mill as dry cement raw meal grinding mill equipment has the advantages of high operational reliability and low energy consumption, and has been widely used in cement raw meal grinding production lines.
1. The problem of cement raw meal grinding
There are many problems to be solved urgently in the cement production process. Among them, energy saving and emission reduction and excess production capacity have become a major problem. As we all know, the main energy consumption in the cement production process is electricity consumption and coal consumption. It accounts for 70% of the total power consumption of the entire cement production line, which requires continuous improvement of the grinding technology in the cement production process. If the power consumption per ton of cement grinding is reduced by 5kW·h/t, 10 billion kWh of electricity can be saved a year, which is equivalent to the power generation of burning more than 5 million tons of raw coal. In order to improve the efficiency and quality of material grinding, domestic and foreign researchers continue to research and improve grinding mill equipment. With the in-depth research in the field of automatic control of grinding mill equipment and the wide application of grinding technology in various industries such as building materials, chemicals, and steel, the advantages of dry cement raw meal vertical roller mill have gradually emerged, and they have become suitable dry-process cement raw meal grinding mill equipment.
2. Introduction of dry cement raw meal grinding mill equipment
Grinding mill equipment is a mechanical equipment used to grind large particle materials into fine particles. It is mainly used in building materials, chemical industry, steel and other industries. After centuries of development, various types of grinding mill equipment have emerged. At present, there are mainly ball mills, vertical roller mills, roller presses and cylinder roller mills. vertical roller mill is a new type of grinding mill equipment produced by people’s continuous research. The GKLM vertical roller mill of Guikuang can be used as a dry cement raw material grinding mill equipment, which integrates crushing, drying, grinding, grading and conveying. The floor area is small, only 50% of the ball mill. At the same time, the grinding efficiency is high and the energy consumption is low. Compared with the ball mill, the energy consumption is 40%-50% lower; the single-machine production capacity is large, and the low-valley electricity can be used, and it has excellent performance in energy saving, emission reduction, safety and environmental protection.
GKLM dry cement raw meal vertical roller mill can be widely used in electric power, metallurgy, cement, chemical, non-metallic minerals and other industries, mainly used for cement raw meal, clinker, power plant desulfurization limestone powder, slag, steel slag, manganese ore, gypsum, coal, Barite, calcite, bauxite and other materials are ground for processing. It has the advantages of low cost, high efficiency and large output. Production capacity: 1-200t/h, finished product particle size: 22-180μm.
