Full ceramic disintegrator

Technical Field

The utility model relates to a preliminary garrulous field of breaking down of bold material especially relates to a full pottery breaker.

Background

In the preparation process of powder materials, the crushing process is often involved, except for the processes of crushing materials into millimeter-sized, micron-sized or even nano-sized fine crushing or even ultrafine crushing, raw materials of a plurality of materials are in a block shape when not being processed, the block size is from several centimeters to dozens of centimeters, some of the raw materials are large-block agglomerates generated after chemical reaction, some of the raw materials are large-block hardened substances generated after high-temperature calcination of kiln equipment, and the blocks can enter the next process only after being preliminarily disintegrated.

At present, large materials are generally treated by a coarse crushing device such as a jaw crusher, a roller crusher and the like. The principle of the jaw crusher is that the blocks are gradually reduced by mutual dislocation and extrusion between the jaws, and finally the discharging requirement is met, but the jaw crusher has the defects that due to the lack of the function of quick striking, if the size of the feeding block is too large or the feeding speed is high, the feeding blocks are easy to accumulate in the crushing cavity, the lower feeding block cannot be crushed as soon as possible, the upper large feeding block cannot be fed normally, the feeding blocks arch with each other, and the bridging phenomenon is caused, it is also possible to intervene manually, if used alone, but if the equipment is installed in an automated assembly line, it causes production stoppage, in addition, if the self-lubricating material blocks such as graphite blocks are not engaged downwards due to the lack of jaw crusher, the material blocks are not discharged but moved upwards when the jaws are dislocated, and the treatment efficiency of the equipment is lowered.

The principle of the roller crusher is that a material block is downwards occluded and extruded and crushed by rotating the roller crusher in opposite directions, but the surface of a common roller is smooth, the material block is large or the material block is low in treatment efficiency when slipping easily, some roller crushers can perform groove drawing treatment on the roller crusher in order to improve the problem during manufacturing, namely grooves are machined one by one, the occlusion force can be enhanced to a certain degree, but the problem cannot be solved completely, large blocks are easy to bridge, and some materials are easy to accumulate in the grooves on the roller crusher after a long time, and the occlusion force can be gradually weakened.
