Two existing forms of tin in nature
Tin have two forms in the nature, one for stone tin, one for alluvial tin. This two forms tin have different machine to separator it.
How to use machine to separator tin
- Stone tin
Stone tin need know the capacity and feeding size. Then base this two information to choose the machine, if the feeding size is for 0-30mm, use ball mill and shaking table, If the feeding size >30mm, need use crusher grinding first, then to ball mill grinding again. Last step use shaking table for concentration.
Our factory have a stone tin project in Algeria. This tin mining process capacity is for 10 tons per hour, feeding size is for 450mm size. First use two step jaw crusher grinding stone tin in 0-20mm size. Then to ball mill grinding again, most time ball mill working with spiral classifier, spiral classifier can make big size to ball mill again, The small size to shaking table. Pls see the below picture. In the picture also have mixing tank and hydraulic box, it can uniform feeder material, and can separator different size again to shaking table, shaking table use different deck, Then improve the tin recovery rate.
