Abstract

The invention discloses an ultrafine grinding system. The ultrafine grinding system comprises a grinding main body, wherein the grinding main body is also connected with a grinding motor and a classification electrode, and is also connected with a vortex cyclone collector, a pulse belt-type deduster as well as a high-pressure draught fan sequentially; the high-pressure draught fan is also provided with a silencer; the grinding main body comprises an ultrafine impact mill which is arranged on the lower end and is connected with the grinding motor through a belt wheel; and a classification machine is also fixed on the upper end of the ultrafine impact mill, and is connected with the classification motor through a belt wheel. According to the ultrafine grinding system disclosed by the invention, a structure for charging materials from a lower opening is adopted, so that materials are effectively re-grinded; the grinding efficiency is improved; the device energy consumption is lowered; further the cost required for production is saved; meanwhile, a shaping effect is generated for the materials; and the development in the industry is improved further.

Description

technical field [0001] The invention relates to a crushing system, in particular to an ultra-fine crushing system used for material crushing. Background technique [0002] At present, the crushing device mainly uses the impact mill to crush the material, and the granular material smaller than 10mm is continuously and uniformly added into the crushing chamber by the feeder, and under the action of the high-speed rotating hammer head, an airflow is formed in the crushing chamber Circulation, the particles rotating with the air flow impact, collide, rub, and shear each other, and at the same time, under the action of centrifugal force, the particles rush to the ceramic lining to be impacted, rubbed, and sheared, and are repeatedly crushed into fine powder. The position of the material inlet is above the hammer head. After adding materials, some of the lighter materials will rise with the airflow, and bounce back after hitting the classifier for crushing, which greatly reduces t...
