Vertical Calcium Carbonate Grinding Machine VRM Roller Mill 80t/H

Product Specification

Capacity 80t/h Vertical Grinding Mill Vertical Mill Limestone Grinding Plant

Description:

HVM series vertical pulverizer is an energy-saving advanced pulverizing equipment that integrates drying, grinding, grading and conveying, which has been researched and developed for many years.
HVM vertical mill has the advantages of high grinding efficiency, low power consumption, large feeding particle size, easy adjustment of product fineness, simple equipment process, small footprint, low noise, low dust, easy use and maintenance, and low operating costs. The consumption of wear-resistant materials is less and so on. 

【Application field】

Widely used in electric power, metallurgy, cement, chemical industry, non-metallic minerals and other industries, mainly used for cement raw meal, clinker, power plant desulfurization limestone powder, slag powder, manganese ore, gypsum, coal, barite, calcite, bauxite Soil and other materials are ground for processing.

【Characteristics】
1. Change the speed ratio of the original reducer, adjust the speed of the reducer for different raw materials through the frequency converter, and improve the grinding efficiency of the mill.
2. Change from two rollers to three rollers, without changing the general frame of the original mill, change the two rollers of the mill into three rollers, increase the grinding area of ​​the mill and increase the output of the mill.
3. The straight blade is changed to "Z" blade. By changing the shape and quantity of the original dynamic and static combined separator, the product fineness can reach 325 mesh and the pass rate is more than 90%, the output is increased by 10%, and the energy consumption is reduced by 15%.
4. Reasonable system configuration, reduce investment in supporting equipment, and reduce system power consumption.

Product Advantages:

1. The superfine vertical mill adopts the principle of high-efficiency and energy-saving material layer grinding, with high grinding efficiency and low energy consumption; the single machine has a large production capacity and can utilize low-valley electricity; the vertical grinding technology and equipment are new energy-saving and consumption-reducing technologies vigorously advocated by the state. , which is conducive to enhancing the competitiveness of enterprises in the powder industry in this region and even the whole country;

2. Strong applicability and low investment Adopt secondary classification to realize multi-purpose of one machine, strong practicability of equipment, and save investment cost.

3. The product quality of calcite ultrafine vertical mill is stable
(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;

4. Easy maintenance and low operating cost
(1) The grinding roller can be turned 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, which prolongs the service life of the wear-resistant material;

5. Environmental protection
(1) The whole system of HLM 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;

6. Low wear, grinding rollers and disc linings are made of special materials and have a long service life;

7. The calcite ultrafine vertical mill has a high degree of automation: the automatic control technology adopts the German Siemens series PLC, equipped with an automatic control system, which can realize remote control and easy operation. The workshop can basically realize unmanned operation and save operating costs.

8. There is no need to put cloth on the grinding disc before starting the calcite ultra-fine vertical mill, and the mill can be started with no load, eliminating the trouble of difficult starting;
