Factory Price High Efficiency Calcite Vertical Mill For Limestone Calcite Ultra Fine Powder Grinding Mill Machine
Description
Vertical grinding machine production line
Ultrafine vertical grinding is mainly suitable for the deep processing of ultrafine large-scale powders of non-metallic minerals such as calcite, marble, limestone, talc, barite, dolomite, brucite, quicklime, gypsum, slag, phosphate, etc.
Application scope: Cement ultrafine powder processing, calcite processing, barite and dolomite grinding processing
Materials: non-metallic minerals such as calcite, marble, limestone, talc, barite, dolomite, brucite, quicklime, gypsum, slag, phosphate, etc
The vertical mill system developed by the company adopts advanced Siemens PLC automatic control system, achieving intelligent and automated control. The equipment runs smoothly during the production process, and the quality of the produced ultrafine powder is very stable, with a narrow particle size distribution.
This large ultra-fine vertical mill is particularly suitable for the production of fillers and coating grade calcium carbonate in large paper mills, as well as for large ultra-fine powder processing enterprises. The ultra-fine powder products produced by this equipment are widely used in various industries such as paper making, plastics, rubber, PVC, wires and cables, artificial stones, paint and coatings, and their performance and high-quality service are deeply recognized and praised by users.
The company focuses on the turnkey engineering of a complete set of ultra-fine powder production lines, including the design, manufacturing, installation, debugging, and training of complete equipment and processes for crushing, conveying, grinding, grading, and modification of ultra-fine powder fields, and enhances high-quality after-sales service and technical support. Continuously improving the service life of vulnerable parts, increasing production line capacity, reducing product consumption, and further improving product quality have always been the eternal pursuit goals of all employees of Hefei Hengcheng. Customer recognition and satisfaction are a high honor for our Hefei Hengcheng employees.

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.
