In test 3, in which the grid was used to segregate the different sizes of balls, a further advantage of about 4 percent in efficiency is shown. The conical mill in test 4 increased the efficiency to 58 percent more than in test 1. The efficiency with the long (6foot) conical mill was about the same as with the short (3foot) one.

Introduction. An iron ore mill relies on the grinding and impact of grinding balls to complete iron ore crushing. The operating process of an iron ore mill is as follows: first, the ores are poured into the mill, and both the ores and the grinding balls are lifted by the lifting bar arranged on the wall of the cylinder body to a certain height, after which they fall onto the bottom of the mill ...

How a Ball Mill Works. Ball mills work by using balls to grind materials. Materials such as iron ore, paint and ceramics are added to the ball mill. Next, the ball mill is activated so that it rotates — either on its vertical or horizontal axis. As the ball mill rotates, the balls bounce around while striking the enclosed material.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Iron balls like these were and still used by "ball mills" to crush mined ore. A large drum is filled with ore and iron balls and then tumbled to pulverize the ore to powder (part of the reduction/ refining process). Here in Colorado a lot of these are mistaken as "cannon balls", however most are left over from the mining days.
