Through batch grinding tests made to pulverized--coal slag, the previouslysuggestod linear superposition principle of mixed balls is verified further. Onthis principle the suitable ball media for grinding pulverized coal slag is deter-mined, and in production practice the mill output can be increased by 20% whenusing a proper ball media.
Compared equal diameter spherical cylinder media with traditional ball media used in coal mill, the former possess remarkable techno-economical effects in productivity raising, energy-saving and powder quality upgrading, which makes it better prospect in application.
Hot-rolling circulation water in an iron and steel plant is treatd by pressure filter tank filling with modified fiber ball media. The pressure filter tank has a capacity of 8 m3/h to treat the water.
Impurity materials from ball media, stainless steel, and ZrO2 reacted with aluminum and silicon to form complex compounds during plasma spray deposition.
The iron level can be effectively controlled by using ZrO2 ball media.
With a continuous change in the direction of the milling tube acceleration, the position of the ball media likewise changes continuously.
Since fragmentation is readily present even in smaller ball sizes, all milling processes that use larger ball media have fragmentation occurrences.
Particles were weighed and loaded into each milling tube with the ball media in the tube.

The forming and ito influencing faCtors of the protective layer on magnetic liners were investigated. The results showed that,in. the course of the protective layer forming,ball media were the key and preferentially attracted to frame tEe protective layer,and then mineral particles were filled into the gaps among media to consolidate the protective layer.Madia and processed material had great influence on the protective layer.
