High Pressure Ultra-fine Limestone Vertical Mil Vertical Roller Mill Design
Product Description
The main component of limestone is calcium carbonate. Limestone is a raw material for the construction industry and industry. The crushed lime powder is added with water to form slaked lime. The slaked lime can be used as a coating material and adhesive after being prepared into lime slurry and lime paste.
HVM type vertical mill is a kind of safety, environmental protection, energy saving, high efficiency, which is designed and developed through painstaking research on the basis of widely absorbing the advanced technology of various vertical mills at home and abroad and drawing on a lot of engineering application experience. Advanced grinding equipment integrating drying, grinding, powder selection and conveying functions. The main performance and economic and technical indicators of the equipment have reached the international advanced level.

Product advantages:
1. The superfine vertical mill adopts the principle of high-efficiency and energy-saving material layer grinding, with high grinding efficiency and low energy consumption; the single machine has a large production capacity and can utilize low-valley electricity; the vertical grinding technology and equipment are new energy-saving and consumption-reducing technologies vigorously advocated by the state. , which is conducive to enhancing the competitiveness of enterprises in the powder industry in this region and even the whole country;
2. Strong applicability and low investment Adopt secondary classification to realize multi-purpose of one machine, strong practicability of equipment, and save investment cost.
3. The product quality of calcite ultrafine vertical mill is stable
(1) The material stays in the pulverizer for a short time, and it is 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 product adaptability;
4. Easy maintenance and low operating cost
(1) The grinding roller can be turned out of the machine by hydraulic device, the replacement of the roller sleeve lining plate and the maintenance space of the grinding machine are large, and the maintenance operation is very convenient;
(2) The roller sleeve can be turned over for use, which prolongs the service life of the wear-resistant material;
5. Environmental protection
(1) The whole system of HLM vertical mill has small vibration and low noise;
(2) The system is sealed as a whole, operates under full negative pressure, and has no dust spillage, which can basically realize a dust-free workshop;
6. Low wear, grinding rollers and disc linings are made of special materials and have a long service life;
7. The calcite ultrafine vertical mill has a high degree of automation: the automatic control technology adopts the German Siemens series PLC, equipped with an automatic control system, which can realize remote control and easy operation. The workshop can basically realize unmanned operation and save operating costs.
8. There is no need to put cloth on the grinding disc before starting the calcite ultra-fine vertical mill, and the mill can be started with no load, eliminating the trouble of difficult starting;
