Gold Panning Equipment Gold Recovery Bowl Centrifuge
Product Description
Spinning Bowl Concentrator
is a new type of gravity concentration equipment for concentrating gold and other high density minerals,especially for recovery of fine gold which is lost during the operation of the gravitational concentrators(sluice boxes and jigs).It's
used only to a limited extent in small placer operations
.Application shows that the recovery can be as high as 99%, and the concentrating ratio is up to 1,000 times. It's Ideal for use from small prospectors up to mining & exploration companies to bulk sample or process material cost-effectively.
2. Relatively low rotational speed to minimize maintenance requirements ;
3. No added water for bed dilation;
4. Simple construction;
5. Low capital cost;
6. Compact and lightweight;
7. Bowl geometry designed for maximum gold retention.
| Model | Specification | Feeding Size | Feed Density | Capacity | Power | Weight |
| BC-80 | 960*850*750 mm | 0-3 mm | 0--30% | 3-5 t/h | 1.1 kw | 150 kg |
Structure & Working Principle:
lined with rubber riffles along the inner surface. The bowl is mounted on a vertical shaft, which spins at over 100 rpm. Material smaller than 3/8 inch down to 1/8 inch is fed with wash water into the bottom of the bowl. The centrifugal force of the spinning bowl causes a film of material to travel upward along the inside of the bowl. The heavy material catches underneath the riffles and lighter particles are washed out over the rim.
1. Recovery of Gold from Alluvial or hard rock deposits;
2. Upgrading and recovery of gold from concentrates from other gravity separation stages eg jigs, spirals and cone concentrators;
3. Used for exploration and evaluation of gold deposits as well as small production;
4. Other mineral applications include niobium, tantalum, coltan, tin, tungsten, and scheelite,etc.
Compared with above small one,we also supply another type
Centrifugal concentrator
(),which is known as centrifuge or centrifugal chute. Strong centrifugal force produced by high speed spin strengthens the process of gravity separation and effectively recover the ultrafine ore particles,normally feeding size is 0-6mm.Nowadays, centrifugal concentrator is widely used for the recovery of gold, tungsten, lead, manganese, iron, etc.
Our factory provides different types with different capacities,semi-automatic type and full automatic type is available to sell too.
