Description

Technical Field

[0001] The utility model belongs to the technical field of slag powder screening devices, in particular to a slag powder screening device. Background Art

[0002] Slag powder, short for granulated blast furnace slag powder, is a high-quality concrete admixture that is added to cement after drying, grinding, and screening. Screening machines are currently the primary tool used in the screening of slag powder after grinding.

[0003] When the screening machine is working, the material to be screened is mixed with gas in the spiral conveying device and then quickly passed into the screen drum. The impeller blades push the material to be screened to rotate in the screen drum. The material to be screened is subjected to the action of centrifugal force, and the material under the screen quickly passes through the screen drum to achieve the purpose of screening. However, when the screening machine is screening micro-powder particles, since the mesh in the screen drum is extremely small, the mesh is easily blocked by large mineral particles or sticky particles, resulting in low screening efficiency. In addition, the material to be screened in the screen is extremely fine material. The finer the material, the greater the surface area energy. The tendency of fine particles to aggregate and agglomerate with each other is gradually strengthened, and a dynamic equilibrium phenomenon of "grinding and agglomeration" will appear. During the screening process of the screening machine, the agglomerated material to be screened is difficult to pass through the screen drum, and some qualified materials are discharged, resulting in low screening efficiency. Based on this, a slag powder screening device is proposed to solve the above problems. Utility Model Content
