There are several considerations in designing an efficient crushing and screening plant. The first is the raw materials to be crushed. The quarry shot material should be analysed for maximum feed size, gradation, chemical composition, amount of clay, hardness and variations within the deposit or ledges. A list of product sizes needs to be determined as well as the …
Quarrying operations typically include drilling holes along the perimeter of the bench followed by cutting the stone out of the deposit using saws equipped with diamond belts, or by splitting the stone using hydraulic splitters.

When upgrading an existing operation there i s much more to consider than if we were building an entirely new plant from scratch – for instance, the proposed adaptations may also require debottlenecking. Step 3: Securing existing crushing operations for implementation. This step requires us to consider the business implications of any changes.
When a quarry wants to optimize, it's easy to concentrate on obvious value-creating events, such as crushing chamber performance. But these only account for about 5% of the entire quarry process. The remaining 95% of activities do not create value – minimizing them gives you excellent potential to boost profitability. Drilling and blasting:
This quarry featured the Mellott-made MC120 Jaw plant. The unit at this location was the first MC120 that we produced and it is still operating beautifully! • Screens: Used to separate materials by size, screens help ensure that only the correct-sized materials move on to the next step in production.
