Ball mill material is ground through the hollow journal

　　Ball mill material is grinded into an empty cylinder through a hollow journal, and a variety of abrasive media (steel balls, steel rods or gravel, etc.) are equipped with various diameters. When the cylinder is rotated around the horizontal axis, the medium and the feedstock to the cylinder and the feedstock are in the action of centrifugal force and friction, as the cylinder reaches a certain height, when the gravity of the own is greater than the centrifugal force, the cylinder is detached. The inner wall is put down or roll down due to impact force. At the same time, during the rotation of the mill, the sliding motion of the mills in the mutagenesis also produces a polishing effect on the raw material. The grinding material is discharged through the hollow journal.

　　Material is uniformly entered into the mill first warehouse by the feed device, and there is a stepped liner or a corrugated liner, and various specific steel balls, and the cylindrical rotation produces centrifugal force. The steel ball is taken behind to a certain height, and the material produces a heavy hit and grinding. After the material reaches a rough mill, the material is entered into the second bin, which is inlaid, and a steel ball is inserted, and the material is further grinded. The powdery is discharged through the discharge blade, and the grinding operation is completed.
