Domestic and foreign profiles are prepared from the powder, the energy utilization rate of airflow pulverization equipment is higher than that of the general mechanical equipment, which is suitable for dry production ultrafine powder.
Although this technological study has been nearly a century in foreign countries, large-scale industrial applications and development are only more than 20 years. Difficulties in airflow, grading principle air flow, is three aspects of crushing, grading, system matching design. Single spray Jet Mill, also known as target-type Jet Mill. Different from the sprayed Jet Mill, the accelerated material is not a shock target, but the opposite high-speed airflow collides with the material in the pulverizing chamber, and achieving the purpose of pulverization. The gas-solid mixture is sent to the grading unit. This pulverizer also has a large strength, high efficiency, small wear area, particularly suitable for crushing high hardness materials, and is more simple. In addition to the same characteristics as
the above single spray, and is the most widely used equipment in the world, and is also one of the mature large-scale equipment in ultrasound pulverization equipment. US, the former Soviet Union has the most applicable. The lower part of the Fluidized Bed Jet Mill is a pulverized region.
The upper portion is a grading area. The material enters the pulverization area through the feeder, and the peripheral ultrasonic nozzle (general 36), the airflow intersection speed vector and should be zero, material No nozzle. When the ultrasound speed is established, the material suspended in the pulling chamber is accelerated by each nozzle air flow and is colliled with the intersection point.
The pulverized material enters the grading area with the wasteworm, and the rotating impeller is divided into the heart ground, and the powder is unqualified and then entering the pulverizing chamber. The principle of gas flow grading is gravity, inertia, centrifuge, with powder performance differences and industrial different uses, classification type, many forms, the most application of the MS type and MSS type grading machine, the typical classification of the heart power field It is the most used classifier for foreign industries.
