Centrifuge Bowl Concentrator

Centrifugal bowl concentrator is one continuous winding rubber riffle type of gravity concentration equipment, used in the gold mining industry for the recovery of fine gold. The centrifugal bowl concentrator uses one continuous winding rubber riffle similar to a screw thread that spirals downward in the direction opposite of the bowl's rotation. This opposite spiral creates continuous self-cleaning riffles by keeping the feed in a slurry state allowing the gold to pull out and press against the wall, it means the bowl can run all day.

SHARE TO:

Processing Materials

Gold, copper, platinum, tin, tungsten, lead, antimony, chrome, titanium.

Application Range

It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.

Advantages and Characteristics

Advantages and Characteristics:

1.High concentrating ratio and recovery for fine gold.

 

2.Removal of both nonmagnetic and magnetic sands without fine gold loses.

 

3.Continuous centrifuge bowl with self-cleaning riffles.

 

4.Environmentally friendly (requires no chemical additives or reagents).

 

5.Low water and electricity requirements.

 

6.Low production costs, durable wear parts, minimal maintenance requirements.

 

7.Compact design requiring less space, easy merged into the existing mining processing.

Product Structure

The hollow shaft of centrifugal bowl concentrator can be driven by electrical motor transmission part through belt driving, making the rotation inner sleeve rotate in a high speed to produce centrifugal force. The centrifugal force pushes the gold not only outward but also upward such that even when gold enters the riffles it is not securely trapped. In fact it will continue to migrate up the bowl’s wall over riffle after riffle until it is lost. Spiral riffles eliminate this loss by forming a gold trap undercut along the bottom of all the riffles.
