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.
The working principle of HLM Series Roll Mill
The motor drives the reducer to rotate the millstone, the raw material are send into the center of the millstone from the air lock rotary feeder. Under the effect of centrifugal force, the material moves to the edge of the millstone. Material than be ground by the force of the roller and smashed under extrusion, grinding and cutting. At the same time, hot air is blew up around the millstone and bring up the ground material. The hot air will dry the floating material and blow the coarse material back to the millstone. The fine powder will be brought to the classifier, and then, the qualified fine powder will flow out the mill and be collected by dust collector, other coarse powder will be brought down to the millstone by the blade of classifier and be ground again. The circulation like this is the overall process of grinding.
Application Range
With scientific & reasonable design and its unique advantages, HLM vertical mills are applied widely in power, metallurgical, cement, chemical and non-metallic industry, for grinding of various materials, such as cement raw material, clinker, limestone, slag, manganese, gypsum, coal, barite, calcite etc.. The grinding field is wide and grinding type is abundant.
1. Humidity of grinding materials: from materials of 20-30% humidity(such as carbide, lignite, chalk, etc.) to materials of humidity less than 1% (such as cement clinker), wide range of materials.
2. Grindability of materials: from high grindability(such as quartz sand, steel slag, mining slag, pyrophyllite, iron ore etc.) to low grindability (such as gypsum, calcite, etc).
3. Fineness of grinding product: from 2-5mm(such as raw shale for making brich in new wall material industry, sand for construction industry, etc) Product fineness is easy to adjust and simple operation.

Vertical Grinding Mill Product introduction The ZY series vertical roller mill is a new and energy-saving grinding mill which is the combination of mature vertical mill technology, foreign successful experience and our company's technological innovation . It has these abilities of crushing, drying, grinding, grading and conveying, and is widely used in cement, electric power, metallurgy, chemical industry, non-metallic ore and slag .and focuses on the three major fields of non-metallic ore, pulverized coal and other materials such as River pebble, granite, basalt, quartzite, iron ore, diabase, limestone, calcite, dolomite, barite, talc, gypsum, bentonite, water slag, steel slag, nickel slag, manganese slag, vanadium titanium slag grinding feldspar etc.
Application of vertical roller grinding mill equipment: Vertical roller grinding mill equipment are suitable for huge capacity producing, widely used in grinding non-flammable and non-explosive materials under 9.3(the Moh's hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc. Advantages of vertical roller grinding mill equipment: 1. Grinding mill equipment in the market designed as a cement grinder and not a modified raw mill 2. Simple layout and fewer machines in the mill circuit ensure high run-factor and low maintenance costs 3. Roller and table profile improve operating stability and reliability 4. Special design features for iron removal during grinding minimize wear 5. Optimal wear protection on all internal surfaces extends lifetime 6. Flexibility to operate with reduced number of rollers guarantees long-term availability 7. Segmented roller wear parts made of the hardest possible material without the risk of cracking; very suitable for hard facing 8. High grinding efficiency: save 20~30% power consumption compared with the ball mill. With the increasing of moisture content, it can save more and more electricity. Working Principle of Vertical Roller Grinding Mill Equipment: The grinding disc is driving by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high efficiency classifier. The qualified powder is taken by the air to the powder collector to be collected, while the unqualified powder is sent back for regrinding.
