River dirt gold with clay, Clay alluvial 4). Desert sand, gold tailing... 5). Tin sand mining 6). Other type mining washing and classify and separation ******* AS per different mining condition, we design the flowchart as below, A). Washing trommel+Centrifugal concentrator+Shaking table; B). Washing trommel+Jig machine(Jigger)+Shaking table; C). Washing trommel+Sluice box with grass mat(carpet). 1). Trommel Screen 1. Working Principle: 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 ---Advantages--- &#9830;Includes water pump, water pipe, diesel engine / electric motor, wheel, can be easy movable.Mobile with wheels, can free transport/move to other lace when finish the job. It is suit to small scale / large mine processing. &#9830; Diesel engine / electric motor, can work in no power field. &#9830; Bigger hopper,single / double layer screen designed. &#9830; Water pump with water pipe release high pressure water. &#9830; It is popular in African, Asian, South American due to its easy to move and easy to operate. &#9830; It is low cost, miner just cost a little budget to buy one. Many miner came to our factory to buy it for their alluvial gold, river sand mineral, diamond mining.
