Most machines have two sets of rollers: Pre-compression rollers; These are the very first rollers in rotary tablet press. Basically, these rollers apply a small amount of force on the upper and lower punches. This gives the initial compression force. The aim of this process is to remove air that could be in the die or powder particles.

The most common centrifuge found in waste treatment dewatering applications is the continuous bowl centrifuge (Figure 37-14). The two principal elements of a continuous solid bowl centrifuge are the rotating bowl and the inner screw conveyor. The bowl acts as a settling vessel; the solids settle due to centrifugal force from its rotating motion.
