Small Gold Mine Equipment Trommel Sand Screen Suice Box for Alluvial Wash Plant

Material feed into the hopper by excavator,high pressure water released and wash the mineral,then,mineral by forward into the drum.It is lifted up by the rotation and aerated as it fall back down.This finer material passes through the screen openings while the large material tumbles towards its eventually exit at the real of the drum.After that,the final mineral and water go through the sluice bow which is consist with gold grass mat.The no use mineral are washed out and the gold are catched by the gold grass mat. China supplier mobile screen river gold washing machine trommel sand screen.

Trommel sand screen is a traditional screening equipment,is designed specifically for material stone screening in quarry, but also used for coal preparation, mineral processing, building materials, electricity and chemical departments for production classification. There are many types vibrating screen machinery, the most applicable in alluvial gold type is eccentric shaft type or vibrating motor type.

When the output form the trommel sand screen , use the gold centrifugal concentrator enrichment the gold particle , then the sluice box to process the taillings.

Introduction of rommel sand screen

1.Feeding System：

A. Streamlined design in Feed Hopper guarantees material can go into the equipment and be separated smoothly in case the material
accumulates in the feed hopper. B. Our specially reinforced 3cm Grizzly is equipped on the feed hopper which can separate away the
big stone bigger than 80 to 150mm. The use of a grid protects the feed hopper and prolongs its service life.2.Screen System：
A. Clay Scrubber is to break off hard clay's to increase gold recovery.
B. The double-layer Trommel Screen is made of high manganese steel wire. The screen support frame is made of 20CrMo with the
strongest hardness. The screen is fixed by screws and is easy for screen changing. The screen exchanging period is more than half
a year longer than other material's screen's 2 to 3 months.

3. Gold Recovery System
A. We designed patented Hydraulic Vibrating Sluice which has a higher recovery rate and not easily damaged.
B. Sluice Box is made of stainless steel. Anti-rust, anti-corrosion, anti-abrasion.Carpet in the sluice is made by Mitsubishi
imported from Japan. Durable, double-layer, anti-skid, anti-abrasion, anti-corrosion,
high recovery rate up to 99%.

4. Powering system
A. Power System is equipped with trailer for easy moving and its brand could be Weichai, Cummins or other brands required by
clients.
B. Power System can be replaced by diesel engine. We always try our best to help clients to save energy and cost.

Rock gold processing plant:

The rock gold processing plant composes of many types of equipment, such as jaw crusher, impact crusher/cone crusher, vibrating feeder, belt conveyor, ball mill, spiral classifier, vibrating screen, spiral separator, centrifugal concentrator, shaking table,flotation machine, mixer, gold smeltng furnace, rotary kiln,and so on. As to how many equipments needed for each model, it's mainly depended on your actual situation and your expectation about the final product, such as the size of the stone, the grade ofthe coarse ore and your expectation on the final product, etc
