Background
The tube mill is a fine grinding device which is important in modern industry, and is one of the most common important devices in a grinding system. The working principle of the tube mill is as follows: the material enters the tube mill cylinder through the feeding device and falls on the initial grinding position of a bin. When the barrel rotates, the grinding medium and the materials rotate along with the barrel under the action of friction and centrifugal force and are lifted to a certain height, then the materials are thrown or shed down according to a certain linear velocity, and the materials are impacted by falling steel balls and large materials and are crushed by virtue of additional crushing and grinding stripping actions between the steel balls, between the steel balls and a mill lining plate, between the materials and between the materials and the steel balls and the lining plate. The material diminishes through the broken granularity that grinds in first storehouse, and less granule is carried two storehouses through the screening and the promotion effect in two compartment, continues to be ground by the less grinding medium of gradation, slowly flows to the discharge end under the effect of material pressure. When the fine powder reaches the discharging end, the fine powder is ground to be very fine in particle size, and after the fine powder is screened by the discharging grate plate, the fine powder with qualified particle size is forced to be discharged from the tube mill by the discharging grate plate and enters the next process.
In the application process of the tube mill, how to strengthen the grinding capacity enables the kinetic energy of a grinding body in the tube mill to be more fully utilized, thereby greatly improving the grinding efficiency, and the tube mill is constantly pursued and searched by technicians in the field. In view of the above, the inventor provides a material section activation device for a tube mill through continuous research, which is applied to a fine milling bin to strengthen powder in the fine milling bin and improve milling efficiency.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a tube mill is with material section activation device, it is used in the fine grinding storehouse, can strengthen the powder in fine grinding storehouse, improves grinding efficiency.
In order to solve the technical problem, the utility model discloses a technical scheme does:
