When a plurality of groups of weight balls 2345 perform circular motion, ingredients with large granularity are stirred and crushed, the ingredients are driven to turn through the filter disc 236 and flow into the charging barrel 21 (the contact area between small-particle ingredients and the filter disc 236 is increased, and the flow is quickened), meanwhile, the filter disc 236 rotates around the inner side of the crushing cylinder 231, the effective filter holes on the filter disc 236 are continuously switched, the filter holes on the filter disc 236 are prevented from being blocked, and the filter holes on the filter disc 236 play a blocking role on grinding media in the charging barrel 21, so that the grinding media are prevented from being crushed by the weight balls 2345. The preliminary kibbling batching flows into feed cylinder 21 through filter disc 236, and dispersion subassembly 24 further grinds it, and it is most to utilize dispersion blade or stick round pin high-speed rotatory direct grinding to compare traditional sand mill, carries out preliminary treatment batching through pretreatment subassembly 23 in advance, improves subsequent grinding efficiency greatly to reduce grinding medium's wearing and tearing and breakage, be applicable to the use of large granule batching in a certain limit, the commonality is strong, saves independent kibbling trouble.
The shielding plate 243 is designed into a circular truncated cone shape, the bottom of the shielding plate 243 is designed into an arc notch, the ingredients which are primarily crushed flow into the notch channel below the shielding plate 243 through the filter plate 236, enter the charging barrel 21, and the ingredients flow out through the discharging valve tube 247 on the dispersing assembly 24 after grinding, so that the flowing solvent in the charging barrel 21 forms a unidirectional flowing trend, and the circular truncated cone shape of the shielding plate 243 is matched, so that a large amount of grinding media are prevented from being deposited near the filter plate 236. When the ingredients are primarily treated and pass through the outer side of the rotating dispersion disc 244, the contact area between the dispersion disc 244 and the grinding media and the ingredients is increased by the annular plate 2443 on the outer side of the dispersion disc 244, the grinding media and the ingredients move along with the dispersion disc 244 under the viscosity resistance, are thrown to the inner wall of the charging barrel 21 under the action of centrifugal force to form annular rolling turbulence, and the violent movement among the grinding media generates shearing, extrusion and friction force, so that the ingredient particles among the media are stressed and deformed and generate stress fields. When the stress field reaches the yield or fracture limit of the particles, plastic deformation or crushing is generated, the particles which are not crushed are thrown towards the inner wall of the charging barrel 21 under the action of centrifugal force, and the density of the medium in the region is maximum, so that the grinding and crushing effect is enhanced. In order to improve the grinding rate of the dispersing plate 244, when the ingredients pass through the inner side of the rotating dispersing plate 244, the round hole 2442 drives the grinding medium and the ingredients on the inner side to synchronously move and collide quickly, meanwhile, the poking plate 2444 drives the grinding medium and the ingredients which do not pass through the round hole 2442 to synchronously move circularly, and as the poking plate 2444 adopts an arc-shaped design and the bending degree of the poking plate 2444 from inside to outside is sequentially increased, the grinding medium and the ingredients driven by the poking plate 2444 slide outwards along the inner wall of the poking plate 2444 by centrifugal force, the grinding medium and the ingredients are continuously extruded and bonded together by the bent poking plate 2444, are separated from the poking plate 2444 instantly and are scattered on the outer side of the annular plate 2443 to collide quickly, so that the ingredients particles and the grinding medium are caused to quickly collide, the ingredients particles are quickly crushed, then flow out through the square hole 2441, and the ingredients particles on the inner side and the outer side can be synchronously crushed simultaneously by the dispersing plate 244, so that the grinding speed is greatly improved.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; these modifications or substitutions do not depart from the essence of the corresponding technical solutions from the protection scope of the technical solutions of the embodiments of the present invention.
