Based on this, the company has developed powder processing technology and complete equipment with strong targeting, safety, reliability, high efficiency, and energy conservation. The variety of raw materials processed and applied in many industries are diverse, The wide range of fields involved.

The limestone pulverization process can be simply divided into the following steps:

Limestone crushing: Limestone is initially crushed by a crusher for subsequent grinding and processing.

Fine crushing of limestone: The crushed limestone is fed into the limestone pulverizing equipment for grinding, usually using vertical mills, ultrafine mills, rotary mills, etc.

Limestone drying: Fine limestone is fed into a drying equipment for drying to reduce the moisture content of the limestone.

Limestone grading: The dried limestone is graded through a sieve to control the particle size of the limestone powder.

Limestone packaging: After the above treatment, limestone powder can be packaged for convenient transportation and storage.

It should be noted that different limestone pulverization processes may have different details and steps, and the specific process flow needs to be adjusted and optimized according to the actual situation.

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 water are dried in the Contact process with hot gas to meet the required product moisture.

Main features of the product
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 place fabric on 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 mill for a short time, which makes it easy to detect the particle size distribution and composition of the product, and the product quality is stable;
(2) The product has uniform particle shape, narrow particle size distribution, good fluidity and strong 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.
