Aim: reduce all unnecessary costs.
With an MB Crusher MB-HDS323 padding bucket and the carrier a Caterpillar 329D at the quarry extraction point, the coal is reduced in size, in one single-step operation.
CHALLENGE 1. During the rainy season, the coal becomes wet and sticky, making the crushing phase to feed the power station difficult.
→ After extraction, in one motion, the MB shaft screener scoops up the damp coal, the rotating shafts reduce down to smaller size the soft, sticky rocks. While been reduced it was also loaded into the truck. The RM Mixer shaft-mounted is not affected by the dampness nor the stickiness of the wet coal.
CHALLENGE 2. The use of a crushing plant is costly as the coal needs to be hauled from the extraction point to the actual processing stage and then hauled again to the power plant.
→ The MB padding bucket creates a process with extremely low running- costs, eliminating all the middle loading and material moving phases. The coal can be towed to the power plant, ready to be used.
