Description

Technical Field

[0001] The utility model belongs to the technical field of tube mills, and in particular relates to an activated flow-blocking device for a tube mill. Background Art

[0002] Tube mills are an important type of fine grinding equipment in modern industry and one of the most common and important components in grinding systems. Large tube mills have high production capacity. The only difference between a single-chamber tube mill and a short-barrel ball mill is that its length is 2-7 times greater than its diameter. This allows the material to spend a longer time in the tube mill, resulting in a more uniform product fineness and greater crushing. Multi-chamber tube mills are actually more widely used than single-chamber tube mills. In a multi-chamber tube mill, partitions divide the mill cylinder into several chambers. Within each chamber, grinding media are matched to the material's grinding requirements. This allows for staged grinding, chamber by chamber, resulting in higher grinding efficiency and greater specific power output. Tube mills are widely used in the building materials, metallurgy, mineral processing, power generation, and chemical industries to grind cement and other materials. Tube mills feature a high crushing ratio, high production capacity, strong material adaptability, and easily replaceable wear parts. The main components of a tube mill are the cylinder, feed section, discharge section, and transmission section.

[0003] The problem with the existing technology is that during the use of the tube mill, the internal screen is subjected to the impact of the material and the grinding body, and is prone to deformation and wear, which affects the material screening and segmented fine grinding effect; after the screen is partially worn, it is inconvenient to disassemble and maintain. Summary of the Invention
