The process flow of YGM95 high pressure suspension roller mill mainly includes the following steps:

• 1. Crushing: The large pieces of material are first crushed by the jaw crusher (recommended model PE250x400), and then crushed into the particle size range required by the grinding mill.

   

   

• 2. Conveying: The crushed materials are sent to the storage hopper by a bucket elevator for temporary storage.

   

   

• 3. Feeding: The materials in the storage hopper are evenly, quantitatively, and continuously fed into the main mill chamber through the electromagnetic vibrating feeder. The electromagnetic vibrating feeder has the advantages of small size, lightweight, uniform feeding, easy to adjust, power saving, and easy to use and maintain.

   

   

• 4. Grinding: In the main mill chamber, the materials are crushed and ground by the grinding rollers suspended on the plum blossom frame. Under the action of a high-pressure spring and centrifugal force, the grinding roller rolls closely against the grinding ring. Its rolling pressure is higher than that of ultra-fine grinding mills under the same power conditions, so the output is greatly increased. The grinding roller rotates around its own axis while rolling in the inner circle of the grinding ring, and the material is sent into the grinding chamber for grinding through the inclination angle of the blade.

   

   

• 5. Classification: The ground powder is taken away by the airflow of the fan and enters the analysis machine for classification. The analyzing machine drives the blades on the turntable to rotate through the speed-regulating motor, forming a grading effect on the powder. The speed of the blade rotation is adjusted according to the particle size of the finished powder. Materials that do not meet the fineness requirements fall back into the grinding chamber for re-grinding, while materials that meet the fineness requirements enter the next stage with the airflow.
