W-wettable powder can be used for ultrafine pulverization grades with airflow pulverizer
The traditional Chinese herbal medicinal material is performed by gas flow, but also has the characteristics of processing non-pollution, maintaining the original chemical properties of the substance, and the characteristics of the powder shape, but can make the Chinese medicine materials have a unique small size effect, surface or interface effect. Wait, thereby exhibiting many excellent properties; the drug will have new advantages such as quantitative, easy to absorb, specificity, targeting when the drug is pulverized to 10 μm to 1 μm. It is more fully able to give full play to the effects of drugs, improve the efficacy, and reduce the economic burden of patients.Pesticide wettable powder is a basic dosage form that has a long history of pesticide preparations, more mature, and convenient use, which is made of primary medicine, carrier (filler), surfactant (wetting agent, dispersant) The auxiliary agent (stabilizer, aircraft, etc.) is composed and pulverized to achieve a certain fine powder formulation. The pulverized apparatus used by the wettable powder is a gas flow pulverizer, which mainly includes a cylinder, a feed and discharge structure on a cylinder. The cylinder is provided with a grading wheel and a gas flow nozzle. The material is smashed with each other under airflow. The crude material is separated under the grading wheel, and the fine particles that meet the particle size requirements are entered into the discharge wheel by the grading wheel, and then discharged into the subsequent process.
Airflow pulverization is a technique that enables particle friction or generating impact using a high-speed airflow to achieve particle fractionation during operation, to filter qualified particles to screen, thereby increasing Crushing efficiency, energy consumption.
Airflow pulverization is an energy that uses high-speed airflow (300 ~ 500 m / s) or superheated steam (300 ~ 400 ° C) to cause particles to generate impact, collision, and friction, resulting in particulates. The high-speed airflow is generated by the nozzle of the pulverizer, and the high pressure air or high pressure hot air flow is rapidly expanded. Since the speed gradient in the vicinity of the nozzle is very large, most of the crushing effects occur in the vicinity of the nozzle. The collision frequency between the particles and the particles in the comminuted interior is much higher than the collision of the particles and the wall, that is, the main pulverization of the gas flow is the impact or collision between the particles.
