Suspended Vibration Cone Concentrator

【Structure】The suspended vibration cone concentrator is composed of 6 parts: main machine, sorting surface, ore feeding device, water feeding device, ore receiving device and electric control system.

【Working Principle】The suspended vibration cone concentrator is a new type of fine particle gravity separation equipment developed based on the Baigno shear loosening theory and the film concentrator principle.
When the evenly stirred slurry enters the primary selection area of ​​the disc from the feeder at the center of the sorting cone, the slurry flow spreads out in a fan shape and flows to the periphery. During its flow, the film gradually becomes thinner from thick, and the flow rate gradually decreases. The ore particles are moderately loosened and layered on the disc under the action of their gravity and the shear repulsion generated by the gyratory vibration. The rotation of the conical disc brings minerals of different densities into the tailings trough, the intermediate ore trough, and the concentrate trough in turn.
The distribution of the ore layers on the sorting cone conforms to the structure of the laminar slurry film. The top surface layer is mainly light minerals with small particle sizes and low density. The pulsation speed of this layer is not large, and its value roughly determines the lower limit of particle size recovery. Most of the suspended ore particles are discharged into the tailings trough in the roughing area. The rheological layer in the middle is mainly composed of heavy minerals with small particle sizes and high density and light minerals with large particle sizes and low density. This layer has the largest thickness and the strongest Baigno force. Since the particle group in this layer is highly dense and there is no large vertical medium flow velocity interference, the stratification can be carried out close to static conditions, so the rheological layer is a more effective area for stratification by density. As the equipment rotates, some minerals are discharged into the middle ore tank under the sorting effect of the washing water in the middle ore area. The bottom sedimentary layer is mainly composed of heavy minerals with high density. The distribution law of particle size is fine near the top of the cone, and the particle size becomes coarser towards the discharge end. The fine and micro-fine heavy minerals in this layer are easy to adhere to the sorting surface tightly and are not easily carried away by the slurry flow. Therefore, when the equipment runs to the concentrated area, the concentrate can be obtained by the action of the washing water.
