Energy Efficient Vertical Mining Slag Grinding Mill For Cement Grinding Plant
Description
HVM series slag vertical mill is based on years of experience in the research and development and production of vertical mills. For the special products of granulated blast furnace slag, through the painstaking research of multi-unit cooperation professional teams, the vertical mill thermal system calculation, equipment selection calculation.
The ultra-fine grinding equipment developed and designed for the calculation of main parameters and the calculation of the powder separator, which integrates grinding, drying and grading, and has the characteristics of high grinding efficiency and strong drying capacity. It realizes the process simplification, less floor space, less investment, greatly reduced power consumption, long service life and high running rate of ultra-fine grinding innovative technology.
【Working Principle】
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when it passes through the annular groove on the grinding disc. 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 on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

【 An Introduction】
HVM vertical mill can handle materials with good grindability or low hardness (such as clay, gypsum, lime, limestone, etc.), and materials with poor grindability or high hardness (such as quartz sand, steel slag, slag, pyrophyllite, kaolin, organic silicon, iron ore, etc.).
【Solution】
For materials with good grindability or low hardness, due to the good grindability of materials, it is easy to ignore some details when selecting equipment, because vertical mill is a combination of three functions of grinding, drying and powder selection. High-efficiency grinding equipment, when dealing with materials that are easy to grind (such as desulfurized gypsum), the grinding and powder selection capabilities of vertical mills of the same specification are quite different. The amount of powder required for the grinding output. If the original equipment selection is still used at this time, due to the limitation of the powder selection ability, although the grinding output is large, it is still impossible to select the qualified products after grinding in time, resulting in low output of the vertical mill and poor performance. For long-term high energy consumption, uneconomical operation. At this time, it is necessary to consider how to obtain a better balance between the grinding output and the powder selection output of the vertical mill. It is necessary to carry out theoretical calculations based on engineering experience. When selecting equipment, the grinding output and powder selection output are considered at the same time. Customized The selection of equipment should be optimized (such as using the original vertical mill body with a powder separator with greater capacity) to achieve the economy and rationality of equipment selection.
For materials with poor grindability or high hardness, when the materials are ground, there will generally be large wear and tear. At the same time, due to the use of high grinding pressure, the reliability of hydraulic components will deteriorate. Therefore, when selecting equipment, the key consideration is how to deal with wear resistance. In addition to the use of high wear-resistant materials for the main wear parts, the necessary anti-wear measures should be taken for the parts or components involved in wear. Hydraulic components subject to high grinding pressures.
