What are the advantages of vertical roller mill

Article source:admin Popularity:Dateline:2019-09-04 15:05

Vertical roller mill has the advantages of high grinding efficiency, low power consumption, large feed size, easy adjustment of product fineness, simple equipment process, small floor area, low noise, small dust, easy operation and maintenance, low running cost, and less wear-resistant material consumption. It can be widely used in electric power, metallurgy, cement, chemical industry, non-metallic ore and other industries. It is mainly used for grinding raw cement, clinker, lime powder for desulfurization of power plant, slag powder, manganese ore, gypsum, coal, barite, calcite and other materials.
1. High efficiency and energy saving: (1) grinding efficiency is high, energy consumption is low, compared with ball mill, energy consumption is low by 40% - 50%; (2) single machine has large production capacity and can use low valley electricity.
2. Maintenance is convenient and operation cost is low: (1) The roller can be turned out by hydraulic device, and the space for replacing the liner of the roller sleeve and the maintenance of the roller mill is very convenient; (2) the roller sleeve can be turned over and used to prolong the service life of wear-resistant materials; (3) there is no need to distribute material on the abrasive disc before starting the mill, and the mill can start without load. Motion, to avoid the trouble of difficult startup; (4) low wear, grinding rollers, grinding plate lining using special materials, long service life;
3. The cost of comprehensive investment is low: it integrates crushing, drying, grinding and conveying. It has simple process, less system equipment, compact structure layout and occupies only 50% of the area of ball mill. It can be laid out in the open air with low construction cost, which directly reduces the investment cost of enterprises.
4. The product quality is stable: (1) the material stays in the roller mill for a short time, and it is easy to detect the particle size distribution and composition of the product, and the product quality is stable; (2) the product has uniform particle shape, narrow particle size distribution, good fluidity and strong product adaptability;
5. High reliability: (1) The use of grinding roll limit device to avoid severe vibration caused by material breakage during roller mill working hours. (2) A new type of roller sealing device is adopted, which makes the sealing more reliable and does not need to seal the fan. It further reduces the oxygen content in the mill and has better explosion suppression performance.
6. Environmental protection: (1) The whole system of HLM vertical roller mill has small vibration and low noise; (2) the whole system is sealed, operated under negative pressure, without dust spillover, and can basically realize dust-free workshop; (3) the technology and equipment of vertical roller mill is a new energy-saving and consumption-reducing technology vigorously advocated by the state, which is conducive to upgrading enterprises in the region and even in the national powder industry. Competitive strength in the field;
7. High degree of automation: the use of PLC automatic control system, and can achieve remote control, simple operation, easy maintenance, reduce labor costs.
