Since each size reduction stages of crushing is limited to around 6-to-1 (average), you need to blast as fine as possible to minimize the number of stages in crushing and crushers needed to reduce the run-of-mine’s hard-rock most economically as you can.

The drill and blast method is used in many quarries to win stone for crushing, but there are alternatives. Patrick Smith reports. European restrictions on blasting operations are now so rigorous that some quarry operators have abandoned the practice in favour of other methods. One of the major reasons for the regulations is that people living or working near, or even in quarries, could be

Impact crushers are named after the method they use in reducing larger blocks of rocks to smaller grain sizes. As the name suggests, an impact crusher accelerates the feed material to high speed and then flings the fast-moving rocks against the walls of the crushing chamber and each other. This collision, impact, causes the stones to break down

The (total blast) average time required to recover a blockage in the primary crusher was approximately 12 minutes. Considering standardisation, per 1,000 tonnes of production, it was calculated that production lost time due to blockages was reduced from 3.66 blockages/1,000 tonnes in the Exel section, to 2.47 blockages/1,000 tonnes in the Unitronic section of the trial blast.

Jaw crushers are routinely choke fed, as this maximizes production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing, breaking up flaky or slabby particles. If you seek fewer fines, trickle feeding material into the jaw crusher could achieve this. But this would have an adverse effect on particle shape
