Slag powder, it is also known as fine slag powder and granulated blast furnace slag powder, it is often used as concrete admixtures and cement mixtures, which can effectively improve the compressive strength of concrete, reduce concrete costs, and inhibit alkali aggregate reaction , Reduce the heat of hydration, reduce the early temperature cracks of the concrete structure, increase the density of the concrete, and improve the impermeability and erosion resistance.

Of course, slag grinding also requires professional slag milling equipment to complete. For many novice investors who are just entering the industry, how does slag make powder? What equipment is needed for mineral powder processing?What equipment is needed for slag powder processing?

For manufacturers of slag equipment, the properties of the materials to be processed (feed size, water content, hardness/brittleness, etc.) are different, and the specific equipment types and specifications that need to be configured for them will also vary. In order to facilitate you to better understand the slag powdering processing equipment and the pulverizing process, in this article we will take the slag powdering process as an example to make a detailed analysis of its processing equipment and specific processes.

Slag raw materials-belt conveyor-vertical mill (grinding, drying, powder selection)-finished fine powder-air box pulse bag powder collector-air conveying chute, hoist-finished powder storage.

The slag raw material is directly sent to the vertical mill by the belt conveyor, and the fine powder of the finished product after grinding, drying and powder separation is collected by the air box pulse bag powder collector, and then transported by the air conveying chute and elevator into the finished powder storage.

1. Vertical mill, including grinding, drying, powder separation and conveying, can process slag with a particle size of less than 30mm to about 325 mesh. The operation of the vertical mill equipment is relatively stable. Compared with similar slag processing equipment, its system energy saving can reach 30%, and the sieving rate of processed products can reach more than 90%. The capacity of one vertical mill can reach the capacity of multiple Raymond mills or ball mills.

2. Auxiliary equipment for slag processing: belt conveyor, air box pulse bag powder collector, air conveying chute, hoist, etc. The main function is feeding, conveying and other functions, assisting the vertical mill to complete the "lime to slag" processing .
