The horizontal vibratory Centrifuge dries coal in the range of 50 mm down to 0.5 mm.

Schenck said the SCC Centrifuge works on the principle rapidly vibrated material will fluidise and flow with the frictional forces between particles and the basket being decreased. This makes it possible to convey the material along the sloping surface of the basket.

The high gravitational forces created by the rotation of the wedge wire basket drives off the surface water and the coal is dried.

The Schenck SCC has a hinged front door for easy access to the basket for inspection and replacement. The inlet chute is fixed to the door and swings clear of the basket for easy basket removal.

Schenck said the vibration system is a twin mass system which has been tuned so that the excitation frequency is below the resonance frequency of the system. As the mass in the basket increases the resonance frequency decreases and gets closer to the excitation frequency. This means that the amplitude of the vibration increases as the centrifuge is more heavily loaded, making the system selfregulating.

Peak loads will cause a momentary increase to the vibration, in order to clear the overloading and stop the centrifuge from bogging.

The vibration amplitude is also easily adjustable by variation of motor counterweights, enabling the operator to optimise the operating performance of the centrifuge, with regard to final moisture or throughput.
