The graph displays a trend that favours the modified section of the trial blast. An average crusher throughput of 191 tonnes per hour was calculated from the reference section of the blast and 234 tph calculated from the modified end. This equates to an 18.3 per cent improvement in primary crusher throughput for the modified section.
Primary crushing is the first stage of material reduction and can sometimes be the only stage needed to generate the desired product for a job. Depending on the setup, primary crushing will take the larger material that has been blasted, excavated, or reclaimed and process it through an impactor, jaw, or gyratory crusher to generate a …
