Why does vertical roller become so popular?

sbm vertical roller mills Vertical roller mills have gained a firm footing in many branches of industry for size reduction of bulk materials. Typical applications are in power plants and in the cement industry. Like all other bulk material handling and processing equipment, vertical roller mills are subject to considerable wear. Typical zones of wear include material feeding, the mill housing, the grinding tools and the integrated separating systems and material discharge.

About Vertical Roller Mill

Application:

Specialized for the high production of superfine pyrophyllite powder making in glass fiber industry.

Specialized for the high production of gangue powder making in coal industry Specialized for the high production of various of chemical raw material powder making in the chemical industry.

It is a necessary equipment for the high production of mineral powder in the non-mental mine industry and large scale powder making in many other industries.

Working principles of the Vertical Mill CLM:

The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the roller mill from the air inlet. The materials fall down the centre of grinding table from the feeder. Because of the centrifugal force, the materials move to the edge of grinding table from the centre .The materials are crushed by the grinding roller when by pass of the groove on the grinding table. The crusher materials continue to move to the edge of the grinding table until taken away by the airstream. Then the bigger materials fall down the grinding table and the process of crushing continues. When the materials in the airstream pass the separator on the top of the mill, the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of roller mill. In the process of the contact of airstream , the materials are dried to meet the clients’ need at the proper moisture.　Through the adjustment of the angle between the separator and the leaf of wind’s direction (not suitable to the small type of vertical mill), and also the speed of the separator rotor, it can reach the proper fineness of the materials.

Vertical Roller Mill

1. Low investment cost

Because of the integration of crushing ,drying , grinding and classification, the system is simple , the layout is compact. The equipment may be erected in the open air ,which can save the civil construction cost.

2. Low Operation Cost

2.1 High grinding efficiency.

The roller mill use rollers and stuff cover to grind material, Low energy consumption , the power consumption of grinding system is lower 30%-40% than ball mill grinding system.

2.2 Low metal consumption.

Because the roller does not get in touch with millstones directly, the special texture linings and rollers with long life and high utilization reduces operating costs.

3.High drying capacity.

The hot air will get in touch with the materials in the mill, so the Vertical Roller Mill has a high parch capacity. According to control the inlet temperature when grinding to meet the different orders of different humidity level materials.

4.Easy and reliable operation

4.1 Equipment is equipped with automatic control devices, remote control van be realized, the operation of equipment is easy and simple.

4.2 The equipment has a device which prevents direct contact between the roller hard surfacing and the lining plates on the mill table.

5. MStable products quality, uniform particle size.

Distribution retention time in mills is short, control and the detection of product size and chemical composition are made easy, which reduces the mill frequency.

6. Convenient maintenance

By turning the rockers well as oil jack maintenance , the hard surfacing and lining and plates can be maintained within short time, which decreases the outage loss.

7.Environment protection
Small vibration, low noise.

There are no dust overflow under the whole equipment gland bush during running, which fit for the State Environmental Protection demand.
