Description

TECHNICAL FIELD

[0001] The utility model belongs to mica processing equipment technical field relates to a kind of wind suction type mica crushing device. BACKGROUND

[0002] Mica paper is made by mica ore crushing, pulping and processing by paper pulp machine, and the crushing process of selected mica ore is carried out by a crusher. The finer and more uniform the mica powder is, the more stable the quality of the mica paper produced is, and the better the flatness and mechanical properties are. The current crusher basically uses filter screen structure for screening after crushing. This method not only easily causes filter screen blockage, but also the smaller the powder particle size is, the more obvious the filter screen blockage is, which affects the processing efficiency and quality of mica powder. SUMMARY

[0003] The utility model aims at the above-mentioned problems existing in the prior art, and provides a kind of wind suction type mica crushing device, and the technical problem to be solved by the utility model is how to improve grinding efficiency.

[0004] The utility model can be realized by the following technical scheme: a kind of wind suction type mica crushing device, characterized by including cyclone dust collector, crushing mechanism and lifting mechanism, the cyclone dust collector includes dust removal cylinder, inlet pipe and exhaust pipe, the crushing mechanism includes the receiving tank of being set at the bottom of dust removal cylinder, fixed abrasive disc and rotating abrasive disc, the lifting mechanism includes lifting cylinder and auger rotatingly connected in lifting cylinder, the receiving tank is connected with the bottom of lifting cylinder by a connecting pipe, the upper end of lifting cylinder is connected to the middle part of inlet pipe, the inlet of inlet pipe is connected to the gas outlet end of a blower, and a feeding connecting pipe is further connected to the inlet pipe.

[0005] Further, the connecting shaft of the auger is connected with the output shaft of a driving motor, and pulley one is further fixedly arranged on the connecting shaft of the auger. Pulley two is fixedly arranged on the rotating abrasive disc, and the pulley one and the pulley two are connected by a belt.

[0006] The utility model uses cyclone dust collector as the basic component of air separation. The positive pressure airflow is sent from the inlet pipe, the crushed material is poured from the feeding connecting pipe, and the fine particles are discharged from the exhaust pipe with the airflow after entering the dust removal cylinder. The mica dust, i.e. small particle size mica particles, can be filtered by filter bag and other structures. The large particle size particles are settled at the bottom of the dust removal cylinder, and then returned to the bottom of the lifting cylinder after grinding by the crushing mechanism. Under the action of the auger, the large particle size material is returned to the inlet pipe again and enters the cyclone dust collector again. This repeated process can obtain fine mica particles discharged from the exhaust pipe with the airflow. This method avoids the use of filter screen, especially the filter structure inside the equipment, which can improve the working efficiency and grinding fineness. BRIEF DESCRIPTION OF DRAWINGS
