Gold Centrifugal Concentrator
Capacity: up to 100 TPH(ton per hour)
Feeding size: 0-6mm
Application: Single gold recovery of alluvial gold, vein gold ore and polymetallic ore, can also be used for the beneficiation of gold-bearing heavy sand washed by chute and gold dredger
Overview
Introduction: The gold centrifugal concentrator rotates at a high speed, generating a high “G” force, which can separate small gravity recovery gold (less than 50 microns). The centrifugal concentrator can also recover the tailings of gold, chromite, scheelite and other heavy minerals. So as to make better use of the mineral concentrate. With its low cost and good recovery of fine minerals, the application of centrifugal concentrators is becoming increasingly important worldwide.
Advantages
- Often connected with gold trommel scrubber, trommel screen, shaking table, sluice box and other beneficiation equipment, used in alluvial gold processing plants.
- Recovering fine gold from alluvial gold ores with extremely efficient, and low cost.
- Continuous output of concentrate and tailings, high concentrate yield, recovery rate, and high enrichment ratio.
- Low production cost, good wear resistance of wearing parts, simple maintenance, compact design, small footprint, easy to integrate into the process of the existing concentrator
Working principle of Centrifugal Concentrator
The gold centrifugal concentrator is a gravity-enhancing device. The feed slurry is introduced into a rotating drum, and the impeller rotates to form a high-gradient centrifugal field. The ore particles flow on the inner wall of the rotor and are continuously layered and deposited on the smooth inside the centrifuge wall.
The lighter particles outside the bed are removed from the rotor assembly due to their lower specific gravity or smaller size. Heavy particles remain in the concentration zone, where the concentrate is cleaned with fluidized water. A rotor spins the bowl, which throws the feed into the center against the bowl’s walls. Light and fine particles are carried out of the bowl with the tailings while heavy and coarse particles are collected and removed. Industrially they can operate as batch or continuous units, with pores opening intermittently to collect concentrate.
