1. It is composed of body, middle body and lower body. 2. The crushing knife is composed of a 7-type knife, a type knife and a centrifugal knife. 3. Auxiliary engine:; It is composed of fan, powder collector and dust remover. 4. The host machine crushing chamber adopts 7-type knife, -- type knife and centrifugal knife, including coarse crushing, fine crushing and centrifugal powder recovery Crushing: the motor drives the rotor of the crusher to run at a high speed, which makes the machine generate high speed airflow and produce high strength of impact force, compression force, cutting force, friction, to achieve a unique crushing function. 5. In the process of cutting and smashing with three kinds of blades, the rotor generates high speed airflow that rotates with the direction of the blade, and the material The airflow accelerates and repeatedly impacts, cuts and rubs, and at the same time receives three kinds of crushing effects. The crushed materials enter the analyzer with the airflow for analysis. As the centrifugal force of the analyzer rotor acts on the centripetal force of the airflow, when the centrifugal force is greater than the centripetal force, the fine particles enter the powder collector with the airflow for collection, and the coarse particles enter the centrifugal re crushing chamber to continue crushing until they reach your satisfactory fineness.
