A method of estimating practical blast patterns for a quarry is presented The existence of a model for the prediction of fragmentation from blasting and the need of feeding the fragments into a fixed primary crusher what ever the variability of the rock properties suggested the need to develop a procedure able to combine a blast model with the well known Bond equation for size reduction
The primary crusher is a vital part of the extractive process taking the run of quarry aggregate and reducing it to a size that can be processed by the downstream operations The mass of material you are blasting blasting polygon appears to be the typical aggregate type therefore the blast design was unchanged After blasting an
