Pesticide wettable powder is a basic dosage form with long history, mature technology, and convenient use in pesticide preparations. The auxiliary agent (stabilizer, sheriff, etc.) is composed of and crushed to a certain fine degree of powder preparation. The crushing equipment used in wettable powder is the airflow crusher. The structure mainly includes the cylindrical body. The inlet and discharge structure is set on the cylinder. Under the action of grading wheels, the thick and thin material is separated, and the fine particles that meet the granularity requirements enter the rawr through a hierarchical wheel, and then discharge into the follow -up process.
The crushing airflow is to use high -speed airflow to rub the particles or produce impact to achieve granular powder. Filter the qualified particles out of the machine, thereby improving crushing efficiency and saving energy consumption. Empty crushing is a device that uses high -speed airflow (300-500m/s) or overheating steam (300-400 ° C) to make the particles impact, collide and friction, which leads to particle crushing. The high -speed airflow is caused by the nozzle installed around the crusher, which is quickly expanded after spraying high -pressure air or high -pressure thermal airflow. Because the speed gradient near the nozzle is large, most of the crushing effects occur near the nozzle. The collision frequency between the crushed room particles and the particles is much higher than the collision between the particles and the wall of the organ, which means that the main crushing effect of the crushing of air flow is the impact or collision between the particles. Qingdao Youmingke Fan Machinery is the source manufacturer of airflow crusher. It can not only be used for ultra -fine crushing processing of wettable powder, but also for high -purity requirements such as super hard diamond, silicon carbide, metal powder, etc.: Ceramic color, medicine, biochemical, etc.
