How To Separate Steel Rods From Concrete In Mining Mill

The two chambers have a certain quantity of ball charge of different sizes from 17mm to 90 mm. The mill discharge is fed to a bucket elevator which takes the material to a separator which separates fine and coarse product. The latter is sent to the mill inlet for regrinding and the final product is stored in concrete.

how can i separate the steel from the concrete

2020-7-27  Then the remainder of the concrete is poured on top. The weight of this concrete will push the steel mesh down slightly, therefore landing it more or less in the center. Steel mesh “sandwiches” can also be placed before any concrete is poured, but for a single sheet of mesh, the above method is sufficient. 9. Trying to do the work alone.
