ABSTRACT:
A method for concentrating and dewatering fine-grained materials wherein the material is delivered by a feeder to the central portion of a pressing chamber in an arcuately shaped housing. A profiled sieve is mounted in the housing. An electric motor imparts a vertical-elliptical oscillatory motion to the housing at a frequency up to 160 Hz and at an amplitude from up to 5 mm.
An apparatus for performing the aforementioned method, comprising a frame on which an electric motor is secured. A housing is supported by springs on the frame. The housing is arcuately shaped and a sieve extends along the whole length of the arcuately shaped housing. The sieve divides the housing into a pressing chamber and a dewatering chamber. In the bottom portion of the dewatering chamber there is provided a pipe for discharging liquid from the dewatering chamber. In the axes of the springs supporting the housing there are provided regulator bolts for limiting the amplitude of the vibratory motion of the housing.
