Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
Finally, 1t presents a time series model for predicting emissions which takes Into consideration the correlation of the sulfur content of the coal, the measuring errors, and the sampling procedures for coal collection. The model 1s used to fit 53 data sets with little evidence of nonfit.
