Working principle and technological process of air flow pulverizer

With the continuous development of air grinder technology, air grinder has gradually penetrated into people's daily life In this paper, we sorted out the working principle of the air flow pulverizer, hoping to help you Working principle of air flow crusher: the power of the machine adopts purified and dry compressed gas, which is injected into the crushing chamber at high speed through a special supersonic nozzle The air flow carries the material at high speed, which causes strong collision, friction and shearing between the material and the material to achieve the purpose of crushing and enter the collection system The crushed materials rise into the classification chamber, and the materials meeting the particle size requirements pass through the forced impeller classifier, and the particles failing to meet the particle size requirements return to the grinding chamber for further grinding The whole production process is totally closed and continuous operation without dust pollution, and the air is purified after dedusting and filtering The pulverizing principle of air flow pulverizer determines its typical characteristics of wide application range, fine product size and high product purity It can be matched with inert gas to form a new type of inert gas closed-circuit protection crushing production line, which is widely used in the crushing processing of inflammable, explosive, easy to oxidize and other materials In the process of pulverization and classification of air flow pulverizer, the pressure gas flows through the high-speed jet formed by the feeding ejector, which makes the raw materials into the pulverizing chamber The pulverizing nozzle on the periphery of the pulverizing chamber sprays high-speed airflow to the pulverizing chamber in a directional way, which causes fierce collision, shearing and friction between the powder materials, thus being crushed The high-speed jet forms a strong swirl in the grinding chamber, and the centrifugal force generated makes the powder particles move at high speed around the grinding chamber When the particle size is crushed below the classification diameter, the centrifugal force is reduced and the centripetal air flow is applied to break away from the classification swirl and enter the capture system from the central outlet The process flow of the air flow pulverizer is connected and controlled by pipes and valves In addition to the pressure requirements, the air source used by the air flow pulverizer must be oil-free, water-free and dust-free to ensure the purity and pulverizing performance of the product At present, oil-free lubrication air compressor and freeze type compressed air dryer are commonly used together to ensure the cleanness of air source In order to ensure a stable gas-solid ratio and a stable particle size range, an automatic quantitative feeder must be equipped The catching system is composed of cyclone separator and pulse bag catcher The catching efficiency is higher than that of the former It is used to ensure the economy of production and not pollute the environment.
