Air Classifier Mill MJW-L
MJW-L air classifier mill is driven independently by the horizontal crushing disc and classifying wheel, and the classifying wheel is installed vertically. The material is evenly fed into the grinding chamber by the feeding system, and is strongly impacted by the high-speed rotating crushing disc, and at the same time, it is subjected to centrifugal force and collides with the crushing ring gear. The comprehensive effect of various forces such as impact, shear, friction, and collision to make the material into powder. The ground material moves to the classification area with the airflow, and the coarse and fine materials are separated by the frequency conversion regulated classifying wheel. The fine powder products that meet the fineness requirements are brought into the cyclone and dust collector by the airflow, and the coarse materials are returned to the grinding area for re-grinding.
Equipment type features
- The design of the internal area and flow field is more flexible, and the scope of application is wider than that of the traditional air classifier mill.
- Classifying wheels with different structures are suitable for powder products with different characteristics.
- Low temperature design, suitable for high-efficiency grinding of heat-sensitive materials.
- High temperature design, suitable for high-efficiency drying, grinding and dispersing of high-humidity materials.
- Inert gas closed circuit design/pressure shock design, specially used for crushing flammable and explosive materials.
- Integration of grinding and classifying, classifying wheel is adjusted to obtain ideal particle, and the classifying rotor can be installed horizontally or vertically.
- The gasket is made of silicone gasket in accordance with FDA food grade requirements.
- The spindle and bladed axle are made of 40Cr steel.
- It can produce products with multiple particle sizes at one time; grinding is in closed system, low dust and noise, clean and environmentally friendly production process.
