Rod mill, which is a top grinding equipment widely used in concentrating, artificial sand making, chemical and power sectors, is named by the grinding loaded bars in cylinder body.

The particle size of the finished products produced by the rod grinding mill is within the range between 4.7mm and 0.4mm. 80% of the feeding mineral particles are smaller than 20mm-4mm and sometimes they can reach as large as 50 mm. Considering the materials which are used to make rod grinding machines, we usually adjust the diameter of the grinding rod at 75-150mm and the rod length at less than 6.1m. Or else, the grinding rods will work in disorder. Therefore, the size of the rod separating machine shouldn’t be larger than 4.6*6.3m.

Working Principle of Grinding Rod Mill

When grinding rod mill works: motor drives the rotary cylinder through the rotation of reducer and surrounding large gear or it directly drives the cylinder with the rotation of surrounding large gear. The body of cylinder has installed appropriate grinding media - steel bars. They are raised to a certain height by centrifugal force and friction, and then fall down with the falling down or drain off state. Grinded materials are continuously given to the cylinder from the mouth, and then crushed by the movement of the grinding media. Finally, the materials will be discharged by the strength of overflow and continuous ore feeding so as to move to the next step.
