Calcite Vertical Mill Powder Production Line | Petroleum Coke Vertical Grinding System | Ore Powder Mill

Description

Calcite becomes heavy calcium carbonate after ultrafine grinding, and large-scale ultrafine crushing and grinding equipment for calcite plays a major role here. What is a complete large-scale ultrafine crushing and grinding production line for calcite? Hefei Hengcheng, a large-scale vertical grinding mill manufacturer, will introduce it to you.
Calcium carbonate is an indispensable inorganic filler in many industries, which can be said to be closely related to our daily lives. For example, in home decoration, latex paint, drainage pipes, artificial floor tiles, wires, and so on are all produced by adding calcium carbonate. There is also the disposable masks we used during the epidemic, which contain calcium carbonate in the non-woven fabric inside.
Calcite is one of the main ore raw materials for the production of calcium carbonate. The higher the natural whiteness of calcite, the less impurities it has and the higher its grade. After being processed by large-scale ultrafine crushing and grinding equipment, calcite becomes heavy calcium carbonate, which is also the most consumed type of calcium carbonate product. Corresponding to heavy calcium is light calcium, which is formed by calcining limestone, digesting it, and then carbonizing and dehydrating it. It belongs to chemical processing, while heavy calcium is a physical process that is simpler and does not cause excessive secondary pollution. Therefore, heavy calcium has more market space and potential than light calcium, but it requires surface modification to keep up with light calcium in terms of its performance.
At present, the ideal large-scale ultrafine crushing and grinding equipment for calcite in the market is a large-scale ultrafine vertical grinder. Ultra fine vertical grinding is a suitable equipment choice for processing mid to high-end ultra-fine heavy calcium. It is advisable to have a feed fineness of less than 1 centimeter, and a discharge fineness from 325 mesh to 2500 mesh, which can achieve stepless adjustment. On the basis of ordinary coarse powder vertical grinding, Hefei Hengcheng has developed the HVM ultrafine vertical grinding machine through dedicated research and development, which is a high-quality large-scale ultrafine crushing and grinding equipment for calcite.

The product fineness can reach 10 um(1250 mesh)

The large-scale ultrafine crushing and grinding production line for calcite includes crushing system, grinding system, grading system, dust collection system, conveying system, and electric control system. Hengcheng can provide a complete set of production line design solutions and equipment support, as well as post installation, debugging, operation, maintenance, and hosting services, allowing customers to save money, worry, and effort.

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.
