1 - 45 T/H Vertical Roller Mill Non Metallic Ore Dolomite Vertical Grinding Mill

Professional Vertical Mill 1 - 45 t / h Vertical Roller Mill - Non-Metallic Ore Dolomite Vertical Grinding Mill

Description

1, Application scope of vertical mill
New ultra-fine vertical grinding equipment can be widely used for large-scale ultra-fine dry powder processing of non-metallic minerals such as calcite, marble, limestone, heavy calcium, talc, barite, dolomite, etc.

2,Working principle: The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for re grinding. When the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

The main structure of a vertical mill consists of a separator, a grinding roller device, a grinding disc device, a pressurization device, a reducer, an electric motor, a shell, and other parts. The separator is an important component that determines the thickness of the grinding product. It is composed of a variable speed transmission device, rotor, guide blade, shell, coarse powder discharge cone, air outlet, etc. It is an efficient, energy-saving, and fast powder selection device. The grinding roller is the main component for rolling and grinding materials. It is installed on the bending arm of the grinding machine, and under the action of external force, it tightly presses on the material of the grinding plate. Under the drive of the grinding plate, the grinding roller rotates accordingly, causing the material to be crushed by rolling. The grinding disc is fixed on the output shaft of the reducer, and the upper part of the grinding disc is a material bed. There is an annular groove on the material bed, and the material is crushed by the grinding roller in the annular groove. The pressure device is a component that provides grinding pressure for the grinding roller. It consists of a high-pressure oil station, hydraulic cylinder rod, accumulator, etc., and can apply sufficient pressure to the grinding roller to crush the material. The reducer is the main component for transmitting power, and the speed of the grinding disc is the output speed of the reducer.

3,Vertical Roller Mill Advantages and highlights
The ultra-fine grinding machine equipment is a fine powder mill with multiple advantages such as rolling, grinding, and impact. It has significant advantages and many advantages. It is a new energy-saving and consumption reducing process, economical and practical, with high cost-effectiveness, more stable performance, and excellent environmental protection.
1) Protection of the environment
Adopting pulse dust removal, the dust removal efficiency reaches 99%, meeting the production requirements of energy conservation and environmental protection.
2) Minor wear and tear
The base of the host adopts integral casting, and the grinding wheel and grinding wheel are made of high-quality materials, with a long service life and good shock absorption performance.
3) Good level
Fine grade, using a wind classifier to make the classifier particles finer and finer.
4) Universality and Compatibility
Provide customers with personalized choices, flexible ratios, and scientific quotations.
