Gravity Separation Equipment
Centrifugal Concentrator
The centrifugal concentrator applies high G-forces to amplify density differences, recovering fine heavy minerals that conventional gravity devices can miss. It handles fine feed particles, making it effective for gold, tungsten, tin, and similar dense minerals.
Technical parameters
In a circuit, the unit typically sits after classification, treating undersize from hydrocyclones or screens. It can also serve as a rougher or scavenger in alluvial and hard rock plants.
The series progresses from compact units for laboratory or pilot use to high-capacity production machines. Selecting the right model involves matching the solid throughput, feed particle size distribution, and desired G-value to the ore characteristics and mass balance. Fluidization water and feed concentration also influence performance.

Standard-model catalogue figures. Actual capacity, power draw and wear life shift with ore properties, feed gradation and circuit conditions. Use them to shortlist, then confirm the duty by testwork, flowsheet calculation and a written confirmation from the manufacturer.
What decides the selection
Before choosing a model, define the feed tonnage, particle size distribution, and head grade. Mineralogical analysis confirms liberation size and gravity-recoverable mineral content. Water availability and quality affect fluidization, while site altitude can influence motor selection. Consider the target mass pull to concentrate and circuit configuration. A testwork programme with representative samples reduces scale-up risk.
