Environmental Protection Energy Saving Vertical Mill Limestone Vertical Mill
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 plaster. There is a lot of demand in the industry, so many customers ask what are the limestone powder vertical mills?
HVM vertical pulverizer is designed and developed on the basis of absorbing advanced technology and combining with Hengcheng's decades of experience in the production of pulverizing equipment, which integrates five functions of crushing, grinding, powder selection, drying, and material conveying. The comprehensive large-scale grinding equipment has the characteristics of centralized process flow, small footprint, low investment, high efficiency, energy saving, environmental protection and so on.

Re:The data based on Mohs'hardness 3-4 material
Limestone Bond Index≤13kwh/t
Structural principle:
(1) Flow chart of double dust collection system
This process plan uses a cyclone dust collector for product collection, which can effectively reduce the working negative pressure of the system and the amount of gas passing through the dust collector. , raw ore, etc.
(2) Flow chart of single dust collection system
The dust collection device used in this art scheme can be a high-concentration electrostatic precipitator or a bag, and the outgoing gas directly enters the dust collector. This system reduces the number of equipment and simplifies the system configuration. It is mostly used for grinding cement clinker, slag, Steel slag, non-metallic ores and other mineral materials.
(3) The dust collection device used in this process plan is an explosion-proof bag dust collector, and the gas from the grinding directly enters the dust collector. At the same time, the system has good airtightness and high safety. It is mostly used for grinding raw coal, petroleum coke and other flammable and explosive materials in cement, metallurgy, coal chemical industry, lime kiln pellets, heat and energy industries.
Advantage
(1) High grinding efficiency and low energy consumption, compared with ball mills, the energy consumption is 40%-50% lower;
(2) The single-machine production capacity is large, and the low-valley electricity can be used;
(3) Vertical mill technology and equipment is a new energy-saving and consumption-reducing technology vigorously advocated, which is conducive to enhancing the competitiveness of enterprises in the powder industry in the region and even the whole country;
(4). Easy maintenance and low operating cost
5) High degree of automation: The automatic control technology adopts German Siemens series PLC, equipped with automatic control system, which can realize remote control and easy operation. The workshop can basically realize unmanned operation and save operating costs;
