China Alluvial gold washing trommel screen is the equipment for elutriating gold from sand mines. Due to the large proportion of gold, generally, the gold is recovered by gravity separation, that is, using water flow as a medium, and washing the sand mines with high pressure water. The minerals with large specific gravity settle and the minerals with small specific gravity flow away, so that gold can be recovered.

The process of gold wash machine is designed according to the situation of the ore body. The main classifications are as follows:

1. Chute sand gold equipment: It is to place gold felt in the chute. After the mineral materials are washed, they are screened, and then the gold is recovered using gold carpet

2. Agitating chute sand gold equipment: The process is better than the chute sand gold equipment. By swirling up and down, the water flow forms a vortex, leaving the light sand and mud gold in the agitating chute.

3. Nelson centrifugal concentrator: It is the currently used sand gold equipment. By supporting the Nielsen beneficiation machine, it can recover both fine-grained gold and large-grained gold. The comprehensive recovery rate is 90%.



China Alluvial gold washing trommel screen introduction:
The gold wash machine produced by our factory is a kind of mobile gold selection equipment that can be moved on land. It has the characteristics of compact structure, light weight, large processing capacity, simple operation, easy maintenance, and convenient movement. It adopts tire-type movement, and the leveling mechanism is hydraulic leveling and mechanical leveling, which can be configured according to user requirements. This machine contains loading, screening, and chute gold selection as a whole, easy to use and easy to operate, suitable for small gold rush customers who have just entered the gold rush industry test stage, and can be equipped with different types of gold drenched grass according to the different gold particles.

This equipment is mainly used for dry land beaches and rivers. It is a gravity beneficiation equipment and is mainly used for the recovery of individual gold in sand gold mines and vein mines. It can be dragged by excavator, forklift or car.

Gold wash machine integrates the principles and characteristics of the separation of fixed chute and jig, overcomes the phenomenon of fixed chute and adopts dual-channel recovery to collect fine gold with coarse gold and sheet gold, and improves the gold ore dressing recovery rate.


China Alluvial gold washing trommel screen Working Principle:
The excavator feeds into the silo, and the high-pressure water in the silo is used to flush the ore to the drum sieve. The heavy sand with high gold content is processed by shaking table.
