Description

Split-flow type vortex material blocking ring for tube mill Technical Field The utility model relates to the technical field of tube mills, in particular to a split-flow type vortex material blocking ring for a tube mill. Background In the prior art, a material blocking ring is an important component of a tube mill generally, and the main function of the material blocking ring is to control the residence time of materials in the mill and prevent the materials from flowing out too quickly, so that the grinding efficiency of the mill is improved, and the split-flow vortex material blocking ring has remarkable advantages in the aspects of improving the grinding efficiency of the tube mill, reducing energy consumption and reducing abrasion. The optimized material and airflow distribution can effectively improve the running efficiency of the mill and reduce the problems caused by material accumulation and unsmooth airflow. In addition, the adjustable design and the application of the wear-resistant material further prolong the service life of the material blocking ring and reduce the maintenance cost. However, the prior art has disadvantages such as the following: In the running process of the tube mill, frequent friction and collision can be generated between the material and the material blocking ring, so that the surface of the material blocking ring is worn faster. The abrasion not only can reduce the service life of the material blocking ring, but also can influence the sealing performance of the material blocking ring, so that the problem of material leakage or grinding efficiency reduction is solved, and once the material blocking ring is worn, the replacement process is often complicated, the whole device is required to be disassembled or a large number of bolt operations are required to be carried out, so that the time and the labor are consumed, the equipment downtime is prolonged, and the production efficiency is influenced. Disclosure of utility model The utility model provides a split-flow type vortex material blocking ring for a tube mill, which aims to solve the problems in the background technology. In order to solve the technical problems, the utility model adopts the following technical scheme: The utility model provides a material ring is kept off with reposition of redundant personnel formula vortex to tube mill, includes fixed knot constructs, replacement structure has been cup jointed at the top of fixed knot constructs the outer wall, fixed knot constructs including PMKD, fixed protection groove has been seted up at PMKD's top, fixed mounting groove has been seted up to the inboard bottom of fixed protection groove, one side fixedly connected with fixed column at PMKD's top and that are located fixed protection groove.
