Everyone knows that our common graphite grinding machine is working through the material grinding of the ball in the pipe body, but few people know that the shape of these balls also affects. Some studies have shown that the elliptical balls can be selected in the graphite ball mill, which may be better than the circular steel ball.
(1) Compared with the ellipsoid surface of the same diameter, the weight increased by 62%, strong impact force, and improved crushing.(2) rather than the line contact elliptical ball between the point contact ball and the ball is 4 times larger than the contact area, the selective pulverization of the material is good, and the product particle size is uniform, and the pulverization is pulverized. The phenomenon is reduced.
(3) Compared with an ellipsoid with the same diameter, the ball surface area increased by 8%, increasing the contact surface of the ball media and the material, and improved grinding ability.
(4) and the elliptical grape ball liner liner is in linear contact, rather than point contact ball, reducing bushing wear on the ball media, reducing the effect of steel ball and medium-plate rolling mill, thereby reducing wear Media and graphite ball mills, extend the service life.
(5) Elliptical balls also have antistatic, moisture-proof, which can reduce the adsorption of fine powder, reduce full milling.
