Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.

The balls are fed into the ported rotary kiln, where phosphorus is reduced out of the ball and then oxidized to make P 4 O 10 gas, which is cooled and absorbed in water in a standard acid hydrator, producing clean 70% concentration phosphoric acid (SPA). The phosphoric acid can be sold to the fertilizer, animal feed, or industrial markets.
