بيت /optimisation of fragmentation of stone crushing through control blasting
Maintenance costs can be significantly reduced if an operation focuses on the fragmentation of the particles passing through their process. Automated sieving systems can detect and help remove any oversize material before it enters the crusher and causes maintenance problems.

DBA study showing Blast Data and Timed Photos. The study revealed our plugs slowed stemming movement 130%, directing the blast energy into the rock, not up the bore hole. The plugs also decreased the mean average rock size in the post blast muck pile by 27%, which resulted in a 25 tons/hour increase of limestone through the primary crusher.

Crushing The impact of blasting on crushing and grinding was also investigated in mining literature (Workman and Eloranta 2003). Drilling and blasting operation determined the particle size of the crusher feed. Since more energy required to break coarser feed size (Pothina et al. 2007), smaller fragmentation size can provide substantial cost

As a consequence, the profi t of a mining operation can be greatly improved through optimised fragmentation. Other unit operations can be greatly assisted by altering blast induced fragmentation. FINE MATERIAL Excessive fragmentation, often a result of higher than optimum powder factor, leads to generation of signifi cant amounts of fi ne material.

An effective blast, however, puts the primary crusher in a position to process materials with less effort. Still, an effective blast starts with a drill job done well. These days, effective drilling can be achieved through 3D GPS automation that improves hole location precision, minimizes over drilling on hole depth and provides for documentation of asdrilled hole locations.
