THE CATALYST FOR ENHANCED PRODUCTIVITY FROM PUZZOLANA SURFACE MINER PMM2205Surface Miners have proved the skeptics wrong by working successfully and economically in the very difficult IndianMining Conditions.Surface Miners have, for sure, saved on cost and wherever they have worked, they have produced desired quality ofproduct by allowing selective mining and more precise mixing of different grades. A high percentage of overall extraction isachieved too because of the precise nature of cutting of coal/minerals.Surface Miners help achieve good control of the product size . Also, mining leaves behind very well leveled benchessaving huge costs and effort involved road and bench maintenance and handling costs.In a nutshell, Puzzolana Surface Miners will directly produce – 75mm product direct from in-situ coal surface withoutdrilling and blasting.MAIN FRAMERuggedly built sturdy box frame integrated with side plates and lifting jack cylinder to withstand extreme shock loads . Fourtrack steering is provided for efficient steering and control. Height adjustment is electro-hydraulic for achieving fine setting. Under Carriage & TracksThe under-carriage & track assemblies provided are heavy duty type with wider footprint to provide extra tractive effortneeded to ensure effortless movement while cutting to the set depth and provide optimized ground pressure for working insoft ground conditions. This ensures greater depth of cut and the rated production and required productivity from theoverall system. Cutting/milling drumVery robust drum type roll design, wear resistant set with up-milling configuration to achieve uniform depth of cut and near85-87% -75mm product sizing. The drum is driven by Poly V-belt drive with automatic constant belt tensioning system.
