Durable Vertical Coal Mill For Coal, Lignite, Lime Production Lines
 
Description

 
Application field
 

With its scientific and reasonable design and unique structural advantages, HVM vertical mill is widely used in the grinding of various types of materials in all walks of life. Easy-to-grind materials, the product fineness ranges from coarse to fine, the types of powders handled are rich, and there are many industries involved:

① Moisture of grinding materials: from materials with water content of 20-30% (such as carbide slag, lignite, chalk, etc.) to materials with water content of less than 1% (cement clinker, etc.), the material has strong adaptability;

② Grindability of grinding materials: from those that are extremely difficult to grind (such as quartz sand, steel slag, slag, pyrophyllite, iron ore, etc.) to those that are easy to grind (such as gypsum, calcite, etc.);

③ The fineness of grinding products: from 2 to 5mm (such as brick-making raw materials in the new wall material industry, sand-grinding shale in the construction industry, etc.) to 15um with a pass rate of 97% (such as grinding heavy calcium in the paper and chemical industries, etc.), Simple and easy control of product fineness and thickness;

Industries where HVM vertical mills are used: building materials, electric power, steel, energy, thermal power, chemical industry, coal chemical industry, non-ferrous metallurgy, lime kiln, mineral processing and other industries.

Materials that can be processed by HVM vertical mill: ferrite, slag, slag, cement, diamond, iron ore, chrome ore, manganese ore, gold ore, copper ore, aluminum ore, lead-zinc ore, tantalum-niobium ore, polymetallic ore, nickel ore, bauxite, silicon carbide, titanium dioxide, talc, bentonite, calcite, kaolin, graphite, mica, wollastonite, feldspar, dolomite, pyrophyllite, quartz sand, fluorite, limestone, organic Silicon, hectorite, shale, volcanic ash, coal, etc.

 
Technical DATA

Performance characteristics

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.
