Classification type efficient ultrafine grinder

Abstract

The invention relates to a classification type efficient ultrafine grinder comprising a rack (1), wherein a feeding chamber (18), a grinding chamber (14) and a discharging chamber (15) are arranged on the rack (1); a grading chamber (23) is arranged at the top of the rack (1) and is located above the discharging chamber (15); the discharging chamber (15) is connected with the grading chamber (23) through a conveying pipeline I (33); a coarse material discharging opening (34) is formed in the bottom of the grading chamber (23); a coarse material air seal machine (22) is arranged below the coarse material discharging opening (34) in a connected manner; and the lower end of the coarse material air seal machine (22) is connected with a feeding opening (21) of the grinding chamber (14). According to the classification type efficient ultrafine grinder provided by the invention, a material enters the grinding chamber for three grinding processes; the grinded material is fed into the grading chamber; the material with a required fineness enters a cyclone discharging process; and a coarse material falls back to the grinding chamber for secondary grinding, so that the heat of a machine cavity is effectively reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a granulation-type high-efficiency ultrafine pulverizer, which belongs to the technical field of pulverization equipment. Background technique [0002] In traditional Chinese medicine, chemical industry, food and other industries, it is common to crush materials. The casing of the traditional ultrafine pulverizer is composed of a classification chamber and a crushing chamber. The material is sent into the crushing chamber through the feeding mechanism, and the particles are quickly split into For fine powder, due to the effect of wind negative pressure, the material enters the classifying wheel through the guide ring for classification. The classified powder must pass through the gap between the blades of the classifying wheel. Since the powder is affected by three forces at the same time, there is a classifying wheel. The centrifugal force generated by high-speed rotation, the gravity of the powder itself and the centripetal ...

The casing of the traditional ultrafine pulverizer is composed of a classification chamber and a crushing chamber. The material is sent into the crushing chamber through the feeding mechanism, and the particles are quickly split into For fine powder, due to the effect of wind negative pressure, the material enters the classifying wheel through the guide ring for classification. The classified powder must pass through the gap between the blades of the classifying wheel. Since the powder is affected by three forces at the same time, there is a classifying wheel. The centrifugal force generated by high-speed rotation, the gravity of the powder itself and the centripetal force generated by the negative pressure airflow, only the fine powder particles whose negative pressure centripetal force is greater than the centrifugal force and their own gravity can pass through the classification wheel and enter the cyclone separation collection, so some materials will be crushed The chamber is crushed repeatedly, so that the machine chamber generates high temperature, which not only lowers the production efficiency, but also affects the quality of the material, especially when crushing viscous materials, such as various fibers and rhizome materials.
