Description

Bauxite is a new type of Bauxite mainly composed of boehmite, Kaolinite, etc. Its main components are iron, titanium, calcium, etc. Aluminate is a kind of mineral that looks like clay. Its color is usually white or gray. For the grinding of aluminum ore, it is natural to use a professional grinder.
【Grinding Field】: It is used as various non-metallic mineral raw materials with Mohs scale hardness less than 7 and water content less than 6%. It is mainly used for the grinding treatment of talc, Calcite, calcium carbonate, dolomite, potassium feldspar, bentonite, kaolin, graphite, carbon and other materials. It has been widely used in power, metallurgy, cement, chemical industry, non-metallic mineral milling, food, medicine and other industries.
【Performance characteristics】: It has comprehensive mechanical crushing capabilities such as rolling, grinding, and impact, mainly used for deep processing of non-metallic ores. Its characteristics are small footprint, strong composability, wide range of applications, simple operation, convenient maintenance, stable performance, and high efficiency and energy conservation.

Working principle:

The motor drives the grinding plate to rotate through the reducer, and the material falls in the center of the grinding plate from the feed inlet. At the same time, hot air enters the grinding plate from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding plate and is crushed by the grinding roller as it passes through the circular groove on the grinding plate. The crushed material is picked up by the high-speed airflow at the wind ring at the edge of the grinding plate, and large particles directly fall onto the grinding plate 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 plate for re grinding, and the qualified fine powder exits the grinding along with the airflow, The product is collected in the powder collecting device. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

Main features of the product
1. High efficiency and energy saving:
(1) High grinding efficiency, low energy consumption, compared to ball mills, energy consumption is 40% - 50% lower;
(2) Single machine production capacity is large, and low valley electricity can be utilized;
(3) Vertical mill technology and equipment are energetically advocated new technologies for energy conservation and consumption reduction, which are conducive to enhancing the competitive strength of enterprises in the regional and even national powder industry;

2. Convenient maintenance and low operating costs:
(1) The grinding roller can be turned out of the machine using a hydraulic device. The replacement of the roller sleeve liner and the maintenance space of the mill are large, making the maintenance operation very convenient;
(2) The grinding roller sleeve can be used upside down, extending the service life of wear-resistant materials;
(3) There is no need to place cloth on the grinding disc before starting the machine, and the mill can be started without load, eliminating the trouble of starting the machine;
(4) Low wear, special materials are used for the grinding roller and grinding plate liner, resulting in long service life;
(5) High degree of automation: The automatic control technology adopts Siemens series PLC from Germany, equipped with an automatic control system, which can achieve remote control and easy operation. The workshop can basically achieve unmanned operation, saving operating costs;

3. Low comprehensive investment cost:
Integrating crushing, drying, grinding, and conveying, it has a simple process flow, fewer system equipment, compact structural layout, and a small floor area, which is only 50% of the ball mill. It can be arranged in the open air, with low construction costs, directly reducing the investment cost of the enterprise.

4. Stable product quality:
(1) The material stays in the grinder for a short time, making it easy to detect the particle size distribution and composition of the product, and ensuring stable product quality;
(2) The product has uniform particle morphology, narrow particle size distribution, good fluidity, and strong product adaptability.

5. High reliability
(1) Adopt a grinding roller limit device to avoid severe vibration caused by material breakage during the working time of the mill;
(2) Using a new type of roller sealing device, the sealing is more reliable, and there is no need to seal the fan, further reducing the oxygen content in the mill, and improving the explosion suppression performance.

6. Environmental protection:
(1) The entire system of HVM vertical grinding machine has small vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and has no dust overflow. Basically, a dust-free workshop can be realized.
