Reverse gradient body resting on spiral springs.
Polyurethane draining surface with slotted slits. One-way vibration is generated by a pair of counterrotating electric vibrators.
The vibration excursion, thus, the speed at which the sand advances and the relative flo rate are regulated when the machine is at a standstill by changing the angle of the eccentric weights of the vibrators.
Vibrating dewaterers for treating large amounts of sand or mixed alluvial materials
Reverse gradient body resting on spiral springs. Polyurethane draining surface with slotted slits. One-way vibration is generated by a mechanical energizer with counterrotating eccentric weights with oilcooled geared synchronism.
Direct transmission with jointed shaft. The vibration excursion, thus the speed at which the sand advances and the relative flow rate are regulated when the machine is at standstill by adding or removing blocks to and from the housings in the eccentric weights of the energizer.
