Product Description

Product Description

Centrifugal concentrator

Centrifugal concentrator (centrifugal separator) is a kind of high efficiency gravity concentrating equipment. High-speed rotation generates very strong centrifugal force to intensify gravity separation which makes more effective recovery of the fine heavies.

Centrifugal Concentrator

Model: STLB60
Max Feed Size: 0-5mm
Feeding Density: <50%
Production capacity:8-12(t/h)
Concentrate Cycle :2-6 hours(alluvial gold)
1-3 hours(Rock gold)
Concentrate output : 10-20kg

Application:
It is used for the recovery and separation of minerals such as rock gold, alluvial gold, tin, tungsten, iron, titanium, zircon, tantalum, niobium, and other metal ores, particularly for fine and ultra-fine grained individual metal particles.

 

 

 

 

Our Advantages

STLB gold centrifugal concentrator is a type of centrifugal beneficiation equipment suitable for recovering free gold from rock gold, alluvial gold, and polymetallic ores, replacing mercury plate operations. It is an ideal choice for dry land or river sand gold and rock gold mining equipment.

High Enrichment Ratio: Can reach 500-1000 times, improving economic returns. 
High Recovery Rate: The recovery rate of placer gold exceeds 99%; for rock gold with a grinding particle size less than 0.074mm, the recovery rate of free gold can reach over 98%. 
Durable Equipment Part: The thick carbon steel body and 6mm stainless steel cone design reduce maintenance costs. 
Environmental Friendly and Non-polluting: No chemical reagents are required during operation.
The gold discharge cycle for rock is 1-4 hours, and for placer gold it is 4-8 hours

Working Principle

The motor passes through the belt to drive the hollow shaft to rotate the drain pan(cone) troughs at high speed,the mineral material passes the feeding port into it, the mineral material is strengthened under the centrifugal action, and the heavy mineral stays in the drain pan slot . The light mineral is discharged by the tailing outlet, and after backflush water, the concentrate is discharged from the concentrate outlet. and then next cycle operation.

 

Product Parameters

We produce six models of STLB centrifugal concentrators for you to choose from, and also offer GTD fully automatic and semi-automatic centrifugal concentrators, which are even easier to operate.

Application

The centrifugal concentrator can be installed in the indoor or outdoor to be operated without any trouble affected by the environment and geographical conditions. It can be used to recover coarse and fine gold in single gravity concentration system, milling system before flotation or cyanide leaching, tailings recovery system, alluvial / placer gold washing system, concentrate enrichment system.
It can also be installed on the trailer to make a mobile concentrator, or combines with pumps, vibrating screen, ball mill and other equipment to form a skid mounted modular processing plant.
