Design for sampling—preliminary exploration
The jaw crusher product would then be split down by the same ratio, so as to maintain the correct ratios. The usual area of failure of primary samplers is over-coarse feed, but this one would measure the coarse fraction at the same time, thus resolving this issue. A more traditional approach is to use a sampling tower for lump (30 x 6 mm) iron ore.
