Too fast and inefficient media movement (known as cataracting) will generate high impact but also greatlyincrease mill wear. Evenfaster speedwill result in the media centrifuging inside themilland virtually nomillingor movement of media or product will occur. In most cases, the idealmill speedwill have the media tumbling from the top of the pile (the shoulder) to the bottom (the toe) with many …

Hammer Crusher
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
Classifier
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
Sand Washer
The sand washer is a kind of highly efficient sand washing plant, taking the advanced techniques and the domestic physical conditions together into consideration.
Dust Catcher
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.

Effect ofMill Speedon the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. Themillwas rotated at 50, 62, 75 and 90% of thecritical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...
