Working Principle

The motor of LM Vertical roller mill through reducer drive disc rotates, the material through the air lock feeder from the inlet falls central disc, while the hot air from the inlet into the mill. As the disc rotates, the material under the effect of centrifugal force, moving to the edge of the disc, the disc past the annular groove on the roller by rolling and crushing, the material crushed by the wind at the edge of the ring disc with high-speed air from large particles fall directly on the disc re-grinding, the material flow through the upper part of the separator, the role in the rotation of the rotor, meal bucket fell from the cone disc re-grinding, qualified powder together with the air out of grinding, through close dust collecting device, namely products, materials containing water in contact with the hot air in the process of being dried, by adjusting the air temperature, the humidity of materials to meet different requirements, to achieve the required product water. By adjusting the separator, can reach the desired fineness of different products.

Vertical roller mill to improve the production of milling equipment

Vertical roller mill Ore milling equipment in the milling, the production will be affected by many factors, including: finished grain size, material hardness, material humidity, material composition, material viscosity, equipment supporting initiatives Measures of work efficiency and so on.

The higher the fineness of the material after passing through the mill, the smaller the milling capacity of the mill. If the user has a higher demand for material fineness, then we can according to their own ability and economic strength to purchase other equipment. The harder the material then the mill will be more difficult to wear, the wear and tear on the equipment will be more serious. Vertical roller mill grinding speed is slow, so the Vertical roller mill powder grinding capacity is small. In other words, when the material contains relatively large amount of water, the material in the vertical mill machine will be prone to adhesion, but also very easy in the delivery of the material during the blockage. The same wind conditions in the case of qualified materials is not easy to be separated, resulting in milling machine milling capacity decline. That is, when the viscosity of the material is larger, the more prone to adhesion. The greater the viscosity of the mill produced the smaller, but also easily affect the service life of the mill, so be sure to follow the instructions in the use of milling machine to operate. Mill powder in the material before the powder containing more, vertical milling powder will be more affected, because these fine powder prone to adhesion and affect the delivery. For the fine powder content can be more than a sieve ahead of time, and for this situation, we recommend the user before the milling process with a sieve to the material for a screening.

How to solve the problem of high temperature of cement vertical roller mill

Cement ultra-fine grinding mill temperature is too high, including the fan motor fever and bearing temperature is too high and other different phenomena, the user in the face of Raymond Mill problems are too high, the first to clarify the reasons for the temperature rise, and then the right medicine The

1, check the extension pipe is smooth, oil viscosity and grades are in line with the requirements.

2, the cement ultra-fine grinding mill equipment into the powder bearing at the required timely refueling, regular cleaning, replace the oil seal.

3, grinding roller grinding ring bearings to regular refueling.

4, cement superfine grinding mill bearing room temperature can not exceed 70 ℃, if the bearing temperature is too high, to immediately remove the cleaning bearings and bearing rooms and other accessories to clean once.

5, the fan may be the factor is a high wind pressure caused, and sometimes we will unconsciously encountered in the production of fan equipment, so that the fan pressure changes lead to motor fever. This also reminds us in the production must not arbitrarily change the equipment.

6, there is the reason for the cement mill mill itself, such as quality, but off, of course, this requires manufacturers to buy eyes wide open carefully selected, and choose large brands, high-quality equipment, such as Shanghai Shi Bang cement ultra-fine Vertical mill, in the industry was well received.
