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.
Advantages of calcite vertical mill:
1. Efficient and energy-saving:
(1) High grinding efficiency and low energy consumption, compared to ball mills, the energy consumption is 40% -50% lower;
(2) Large single machine production capacity, capable of utilizing low valley electricity;
(3) Vertical grinding technology and equipment are vigorously advocated new technologies for energy conservation and consumption reduction, which are conducive to enhancing the competitive strength of enterprises in the powder industry in this region and even across the country;
2. Easy maintenance and low operating costs:
(1) The grinding roller can be turned out of the machine using a hydraulic device, and the replacement of the roller sleeve lining plate 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) Before starting the machine, there is no need to apply fabric to the grinding disc, and the mill can be started without load, eliminating the difficulty of starting the machine;
(4) Low wear, special materials are used for the grinding roller and disc lining plate, resulting in a long service life;
(5) High degree of automation: The automatic control technology adopts the 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, the process flow is simple, the system equipment is few, the structural layout is compact, and the floor area is only 50% of that of the ball mill. It can be arranged outdoors, 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 flowability, and strong product adaptability.
5. High reliability
(1) Adopting a grinding roller limit device to avoid severe vibration caused by material breakage during the working time of the mill;
(2) Adopting a new type of roller sealing device, the sealing is more reliable, and there is no need for a sealing fan, further reducing the oxygen content in the mill and achieving better explosion suppression performance.
6. Environmental protection:
(1) The entire system of HVM vertical grinding machine has low vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and there is no dust leakage, basically achieving a dust-free workshop.
