Vertical Roller Mill, LM Vertical Grinding Mills

Input Size: 0-70mm

Capacity: 3-340TPH

Material: Limestone, calcite, dolomite, petroleum coal, gypsum, barite, marble, talc, coal powder, etc.

The invention is a vertical roller mill grinding grain stone rural Nianzishan inspired by. Modern vertical milling machine is developed from l906 onwards, it has been continually improved over the past century, experienced a roller by centrifugal force to put pressure on the spring-loaded, and now pressurized hydraulic pneumatic spring system. Is the softest material from the grinding of coal to medium hardness and brittle cement raw materials to cement clinker and slag.

Brief Introduction Of Vertical Roller Mill

LM vertical grinding mill is the world expert on the basis of long-term state company's mill development experience, according to the United States, Germany, Japan and other experts for the Chinese mill use of user requirements and recommendations, based on the original high pressure hanging roller mill on After painstaking research to design a new type milling machine.

Vertical Roller Mill Working Principle

The grinding plate rotates under the action of main motor of LM vertical grinding mill and the reducer. Meanwhile, hot wind enters the vertical mill. After raw materials fall onto the center of grinding plate, they move to the edge of grinding plate under the action of centrifugal force.

While passing through the grinding area between roller and grinding plate, bulky materials are broken directly by the pressure of roller while fine materials form a layer where materials crush each other. Broken materials after grinding continue moving to the edge of grinding plate until they are brought away by the airflow at the air ring.

For coarse materials which cannot be brought away would fall onto the grinding plate for another grinding. When passing the upper separator, materials in the air flow will be divided into two parts by the blades of rotor, that is, coarse particles and fine powders. Coarse particles would be sent back to have another grinding while the qualified fine powders enter the powder collector with airflow as finished products.

For sundries like iron block in materials, when they move to the fringe of grinding plate, because of their heavier weight, they would drop to the lower cavity of grinding mill and next be sent into the discharging port by scarper installed at the bottom of grinding plate and finally be discharged out of the grinding mill.

Vertical Roller Mill Structure And Wear Parts

LM series vertical milling machine mainly separator, roller device, disc device, the pressure part of the device, reducer, motor, housing and so on. LM series vertical milling machine with low investment costs, low operating costs, high drying capacity, easy to operate, reliable operation, easy maintenance, environmental protection, etc., are widely used in power generation, cement, metallurgy, chemical industry, non-metallic mineral industries , is a set of crushing, drying, grinding, milling industry, the ideal equipment for grading conveyor in one.

Vertical Roller Mill Features And Advantages

Low investment costs: As set crushing, drying, grinding, grading conveyor in one, the system is simple, compact layout, covering about 50% of the milling system, and can open layout, so they can significantly reduce investment costs. Low operating costs: First, the high milling efficiency: roller compacted ground directly on the disc material, low energy consumption, save energy and milling system compared to 30% to 40%. Secondly, less wear and tear: As the roller is not working in direct contact with the disc, and the grinding roller and liner made of high quality materials, so long life, less wear and tear.

For grinding materials adaptable, can be used for grinding all kinds of raw materials and fuels, such as limestone, sandstone (Si02> 90%), coal, cement clinker, blast furnace slag. Whether its grindability, abrasive much difference, through internal restructuring and rational mill operation, can produce different fineness, different than the surface area of qualified products.simple and reliable operation: equipped with automatic control system, which enables remote control, easy to operate. Equipped with a device to prevent the roller sleeve and disc liner direct contact, avoiding destructive impact and severe vibration.

high efficiency drying, hot air from the annular slit spray people, wind speed is high, the mill ventilation cross-section of large and small resistance, the use of exhaust gas can be drying kiln preheater 8% moisture content material, if drying stove to bake drying aqueous 15% to 20% of the material. Product quality: because the material in the mill residence time is short, easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.
