air classifier mill pulverizer

タイトルまたは説明

   Introduction
The HENGYUE Classifier Mill, type QWF is a very flexible machine for the production of finest powder with a defined maximum particle size. Materials with a hardness of up to 3,5 Mohs can be processed. The combination of size reduction and dynamic air classifying within one housing allows for optimum processing of soft to medium hard materials. The main areas of application of the mill can be found for example in the chemical, food, mineral, metal, powder paint and pharmaceutical industry.

Decisive Advantages 
—Size reduction and classification in one mill
 
—Air flow regulating valve and classifying paddle governor are installed, and fines can be cycled completely to avoid polluting the environment.
 
—Equipped with the function of exterior-cooling, the temperature rises in a small range during pulverizing. Thus, the machine is applicable to the heat sensitive materials and fibers.
 
— High availability due to easy cleaning
 
—New type of imported V-belts is adopted, so it has the characteristic of high transmission power, high efficiency and stable operation.
 
Method of operation

The QWF II-series pulverization is operated with size reduction and classification in one mill. It is made up of machine body, machine housing, feeding equipment, discharge gate, transmission equipment and dynamo. The interior structure can be seen in the picture. The machine cavity is divided into two parts. The lower part is for inlet of the air. The upper part is divided into grinding zone and classifying zone by the classifying blade. Grinding zone, constructed by grinding plate and bushes, is used to pulverize particles. The classifier zone, manufactured out of stainless steel, is used to classify the fines.
 
 The feed material is pneumatically transported into the Classifier Mill, type QWFII-series. Size reduction is per-formed between the rotating grinding elements of the grinding disc and a stationary grinding path. The size-reduced material is transported into the classifier wheel by means of an upward airflow. Particles with the desired fineness are transported through the beater plates of the classifying wheel and are guided with the airflow into a process filter in order to be discharged. Coarse materials, rejected by the classifying wheel, are introduced into the grinding zone for further grinding. Due to the infinitely adjustable speed of the grinding disc and classifier wheel, the desired fineness and the particle distribution curve are easily adjustable.
