Silica Grinder Roll is an important equipment of vertical mill. It can be pulled out of the machine by hydraulic device. It has a large space for replacing the roller bushing and the overhaul of the mill, and the overhaul operation is very convenient.
Vertical mill also has the following unique properties
1. The grinding roller can be turned out of the machine by hydraulic device, the replacement of the roller sleeve lining plate and the maintenance space of the grinding machine are large, and the maintenance operation is very convenient.
2. The roller sleeve can be turned over for use, which prolongs the service life of the wear-resistant material.
3. There is no need to put cloth on the grinding disc before starting the machine, and the mill can be started with no load, eliminating the trouble of difficult starting.
4. The grinding roller limit device is adopted to avoid the violent vibration caused by the broken material when the mill is working.
5. The new grinding roller sealing device is adopted, the sealing is more reliable, and there is no need to seal the fan.
6. The roller bearings are lubricated by oil immersion, eliminating the need for external circulation lubrication.
7. The external circulation system is adopted to reduce the wind speed at the air ring, reduce the power of the vertical mill exhaust fan, improve the start and stop conditions of the mill, and reduce the cleaning time during maintenance.
Outstanding advantages
1. Low cost: the system is simple, the layout is compact, the floor area is about 50% of that of the ball mill, and it can be arranged in the open air to reduce investment costs
2. High efficiency: Rock Grinder Roll is in direct contact with the material on the grinding disc during work, so the energy consumption is small
3. Strong drying: because the hot air is in direct contact with the material, the drying capacity is large, and the energy-saving type is better
4. Simple operation, stable product quality, convenient maintenance and good working environment
3. Working principle
The material falls to the center of the grinding disc through the feeding pipe, and the grinding disc rotating at a constant speed disperses and flattens the raw material outwardly with the help of centrifugal force, so as to form a material bed with a certain thickness. crushed and crushed. Under the continuous driving of centrifugal force, the material continuously moves to the outer edge of the grinding table. When the material leaving the grinding table encounters the hot gas entering the mill through the wind ring, it rises and enters the separator through the middle shell of the mill. During this process The material in the medium and the hot gas conduct sufficient heat exchange, and the water is quickly evaporated. The powder separator controls the particle size of the finished products at the outlet of the roller mill. The particles larger than the specified size are separated and fall back to the grinding disc. The materials that meet the fineness requirements enter the dust collector through the powder separator, and the collected products are sent to the finished product warehouse.
Philippines Cement introduces how to measure the material level of cement vertical mill
Overview of vertical mill differential pressure measurement method Raw material grinding is an extremely important and primary link in the cement plant process line. The quality of the mill installation is directly related to the normal production of the entire line and the economic benefits after the entire plant is put into operation. During the use of cement vertical mills, due to the harsh working conditions, common problems such as vertical grinding rollers, grinding disc lining wear, vertical grinding roller bearing chamber wear, and reducer leakage often occur.
According to the requirements of the production process, there are two types of material level measuring devices. One is the limit material level detection, that is, the material level switch. Generally, there are two detection points, upper and lower limit. Once the material level reaches the preset material level, a control signal is sent out to make the feeding or unloading equipment perform corresponding actions. The second is continuous material level measurement. There are two working methods: timed measurement and measurement when needed. It is used for the occasions where the height of the material surface is accurately controlled. After the equipment manufacturer has debugged the mechanical equipment, with the continuous production of the cement enterprise, it will be found that the parameters adjusted by the manufacturer are not suitable for the production of the enterprise. Therefore, to a certain extent, the parameter data is adjusted to adjust the production of cement enterprises. To a certain extent, it is also a major innovation in the production technology of enterprises.
Philippines Cement purchased Silica Grinder Roll and other cement plant equipment from AGICO Cement CHINA and recommended info@cementplantparts.com to other cement plants in the Philippines
