What is the slag used for?
1. As a raw material to produce slag Portland cement, granulated blast furnace slag is mixed with Portland cement clinker, and then 3~5% gypsum is added to mix and grind to make slag Portland cement, which can be better used in water engineering , harbour and underground works, etc.
2. It can be used to produce slag bricks and wet-rolled slag concrete products.
3. Put the water slag and activator (cement, lime and gypsum) on the wheel mill and grind it with water to make mortar, and then mix it with coarse aggregate to form wet-milled slag concrete.
4. It can be prepared with slag and gravel concrete, which has a wide range of applications in road engineering and railway engineering.
5. Application of expanded slag and expanded beads Expanded slag is mainly used as lightweight aggregate to make lightweight concrete.

Technical Data

【 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.
