Crushing in Mineral Processing

Since there are not that many small SAG mill operations of under 2000 TPD, and most sub-2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <1.5″ (40 mm) and often as finely crushed as <3/8″ (9 mm).

Methods of Analysis

Timing: Most samples that are smaller than the size of a fist are processed through the Wiley Mini-Mill. On the average, 1 minute per sample if less than 15 grams or 3-4 minutes for samples of 100-150 grams. Samples larger than two fists are sent through the model 4 Wiley Mill. Average time is 4-5 minutes per sample.
