Ball Mill Can Make Materials More Useful

Devices for shaking materials along with hard balls might be old, but it was not until the industrial revolution and the invention of steam power that a machine could be built. It is reported to have been used for grinding flint for pottery in 1870. Rock crushing plant. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method termed mechanical alloying could successfully produce fine, uniform dispersions of oxide particles in nickel-base super alloys that could not be made by more conventional powder metallurgy methods.

A ball mill consists of a horizontally rotating hollow cylindrical vessel or shell with the length slightly greater than its diameter which is mounted on a metallic frame in such a way, that it can be rotated on its longitudinal axis. cement mill price. The axis of the shell or vessel may be either horizontal or at a small angle to the horizontal. The cylindrical vessel contains balls that occupy 30-50% of the mill volume. The grinding media is the balls, which may be made of steel (chrome steel), stainless steel or rubber which the weight of the balls is kept constant. The ball size depends on the feed and the diameter of the mill. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber. Less wear takes place in rubber lined mills.

The powder particles are get flattened by the collision of the balls. It leads it changes in the shapes of individual particles or cluster of particles being impacted repeatedly by the milling balls with high kinetic energy.
