325 Mesh Vertical Roller Mill For Limestone, Calcite, Barite, Dolomite And Feldspar
Description
Limestone vertical mill is a product developed by Hefei Hengcheng Technology in order to solve the technical problems of low output and high energy consumption of industrial mills. It absorbs technology and combines Hefei Hengcheng Technology's many years of mill design and manufacturing concepts and market demand. After years of painstaking design and improvement. Large grinding equipment.
Cement raw material, limestone vertical mill is a combination of fine crushing, drying, grinding, powder selection and transportation. It has the advantages of small footprint, simple process flow, high grinding efficiency, low energy consumption, low noise, large drying capacity, The product has the characteristics of easy adjustment of fineness, no dust pollution, convenient maintenance and reliable operation.
Especially in the large-scale grinding process, it fully meets the needs of customers, and the main technical and economic indicators reach a certain level.
Widely used in large-scale material grinding and ultra-fine powder in metallurgy, electric power, cement, chemical industry, ceramics, non-metallic minerals, power plant desulfurization, water slag, slag, slag, coal, cement clinker, glass, quartz, limestone and other industries Grinding.

【Working principle】
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is ground together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.
【Main features of the product】
1. High efficiency and energy saving:
(1) High grinding efficiency and low energy consumption, compared with ball mills, the energy consumption is 40%-50% lower;
(2) The single-machine production capacity is large, and the low-valley electricity can be used;
(3) Vertical mill technology and equipment is a new energy-saving and consumption-reducing technology vigorously advocated, which is conducive to enhancing the competitiveness of enterprises in the powder industry in the region and even the whole country;
2. Easy maintenance and low operating cost:
(1) The grinding roller can be pulled out of the machine by hydraulic device, the replacement of the roller sleeve lining plate and the maintenance space of the grinding machine are large, and the maintenance operation is very convenient;
(2) The roller sleeve can be turned over for use, extending the service life of the wear-resistant material;
(3) There is no need to put cloth on the grinding disc before starting the machine, and the mill can be started with no load, eliminating the trouble of difficult starting;
(4) The wear is low, the grinding roller and the grinding disc lining are made of special materials, and the service life is long;
(5) High degree of automation: The automatic control technology adopts German Siemens series PLC, equipped with automatic control system, which can realize remote control and easy operation. The workshop can basically realize unmanned operation and save operating costs;
3. Low comprehensive investment cost:
It integrates crushing, drying, grinding and conveying. The process is simple, the system equipment is small, the structure layout is compact, and the floor area is only 50% of the ball mill. It can be arranged in the open air, and the construction cost is low, which directly reduces the investment cost of the enterprise.
4. Stable product quality:
(1) The material stays in the pulverizer 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 grinding roller limit device is used to avoid the violent vibration caused by the material cut off during the working time of the mill;
(2) Adopting a new type of grinding roller sealing device, the sealing is more reliable, and there is no need to seal the fan, which further reduces the oxygen content in the mill and has better explosion suppression performance.
6. Environmental protection:
(1) The whole system of HVM vertical mill has small vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and has no dust spillage, which can basically realize a dust-free workshop.
