SB Super Tank Batch Laboratory Centrifugal Concentrator

SB Superbowl Batch Laboratory

Centrifugal Concentrator

Description:

The SB series of concentrators retains the density of particles in the feed slurry and can periodically produce small but relatively high-grade concentrates (1% by mass). The concentration level of concentrated materials may be high, usually measured in terms of metal percentage, such as 3% Au. The high grade obtained means a very low weight recovery rate, usually<1%.

The heaviest layer crosses over the concentrate bed retained in the trough at the top of the drum. Adding back pressure water from behind the shallow bed can cause heavy target particles to migrate to the bottom of the bed, while prioritizing the retention of lighter particles.

High G-values can even effectively recover very fine particles, while the depth of the concentrate bed can handle coarser particles in the feed stream. When the bed has accumulated to a sufficient level, stop feeding, and the rotor decelerates. The built-in spray manifold flushes the concentrated liquid under the rotor baffle and discharges it from the rotor outlet.

This semi batch process is very suitable for the recovery of fine primary metals (Au, Ag, Pt). Adding process water can enable these devices to process coarser feed streams. The SB device is suitable for recovering fine (as low as 10 microns) and coarse precious metals in free metal state. The maximum feed particle size can be as coarse as 6 mm, but it is recommended to sieve slightly coarser than the maximum target particle size.

The grade of concentrate may be very high, usually measured in terms of metal percentage (i.e. 3% gold, etc.). The high grade obtained means a very low weight recovery rate, usually<1%. The heaviest layer crosses over the concentrate bed retained in the trough at the top of the drum. The SB-40 intermittent concentrator is made of stainless steel, except for the wear-resistant UHMW filter cup. It has a variable speed drive.
