HLM Vertical Roller Mill Pulverizer

Max feeding size: 50mm

Capacity: 5-700t/h

Fineness: 200-325 mesh (75-44μm)

HLM series vertical grinding mill is a kind of advanced pulverizing equipment integrated with drying, pulverizing, powder selecting and conveying. It is applied as a good solution to the technical issue such as low output, high energy consumption and high maintenance cost in the ordinary industry. HLM vertical mill has become the mainstream equipment in the pulverizing industry with the following advantages: efficient grinding, lower power consumption, larger feeding size, adjustable fineness, simple process flow, space-saving, lower noise, smaller air pollution, easy maintenance, lower operation cost, longer working life of wearing parts etc. HLM Vertical Mill is widely applied in power, metallurgical, cement, chemical and non-metal industry, such as cement raw material, blast furnace slag, composite dust, limestone, gangue, gypsum, bauxite, magnesium oxide, wollastonite, zircon sand, diabase, basalt, manganese, powder, coal, barite, calcite, etc.

Performance Features

1. High efficiency

(1) Low energy consumption, high efficiency, 40%-50% lower energy consumption than ball mill;

(2) High single machine output, can use off-peak electricity;

(3) Vertical mill technology is initiated by the country, it can improve the competitive strength of the enterprises in local area or even in the country;

2. Easy maintenance, low operation cost

(1) The rollers can be pull out from the mill by the hydraulic device, which is convenient for plate-replacement and bigger maintenance space;

(2) Left and right side of the roller shell can both be used for prolonging the working life;

(3) The mill can run without raw material on the grinding table, which erases the difficulty in starting;

(4) The roller and grinding table are made from special material for longer working life;

(5) High degree of automation: Applied Germany Siemens PLC series with automatic control system and can realized easy long-distance control and unmanned operation.

3. Low investment cost

The equipment features in a combination of crushing, drying, grinding, and conveying, simple process flow, reasonable and compact layout, space-saving (50% less than ball mill), lower foundation cost and workshop cost in the field;

4. Stable powder quality

(1) Material stay a short time in the mill, easy to control fineness and chemical component;

(2) Regular powder shape, narrow fineness range, good fluidity, extensive application;

5. Reliability

(1) Rollers with height-controlled device, which could avoid strong vibration caused by the lack of material on the table;

(2) Newly-designed roller sealing component ensures the reliable sealing without sealing the blower, which can lower the oxygen content in the mill to prevent the possibility of explosion;

6. Environmentally friendly

(1) Lower vibration and noise;

(2) The whole facility is all sealed and operates under negative pressure, no powder overflow, no-dust workshop can be realized.

(3)Vertical mill is the better equipment to lower power consumption in the mill industry, which is also what the country advocate and a must to increase the enterprise competitiveness in China powder industry.

7. High Automatic Level

(1) PLC automatic control system, remote control, easy operation and maintenance, lower labor cost.

8. Strong Drying Ability

(1) Vertical mill features in high trying ability with hot air direct contact with the material in the mill, maximal feeding moisture of 15% is workable. A separate drying machine and energy for the mill system can be both saved. The vertic
