crushing and grinding photos in sampling process

Dry Process Sampling . after primary/secondary crushing on a conveyor belt will typically show high inhomogeneity in all 3 dimensions: along the length of the conveyor (L), across the conveyor (W) and in the depth of the material layer (D) In addition, particle size segregation may be distinct in the W and D dimensions Needless to say, this puts high demands on the sampling, which is complex ...
