Measurement of Size Distribution of Blasted Rock Using

muckpile. Therefore, reliable evaluation of fragmentation is a critical mining problem[1]. Production of finer fragments in blasting operation reduces the work-load of primary crushers; therefore increasing the crusher efficiency and reducing the crushing cost. Also crushing rate per hour will increase. 2. Size Distribution Analysis Using

fragmentation data from an online system. The results can show a number of different things, but most importantly it tells the operator either: a) The crusher needs to be gapped on a more regular basis based on the increased fragmentation size b)The crusher is being gapped too often when it is not required, allowing for less downtime.

The focus in this review is on the energy expenditure and the influence of blasting on the size distribution and properties of muckpile fragments. Grinding is by far the most energy intensive stage of the comminution process. It is e.g. used both in iron

Unfortunately, in most operations by the time rock is loaded onto a conveyor belt, it has passed through a primary crusher, and the size distribution no longer reflects only the blasting process. On the other hand, imaging and measuring the size of fragmentation on muck piles, while still useful, is problematic. Results can vary because of
