Text of Surface miner






    Surface Miners have proved the skeptics wrong by working successfully and economically in the very difficult Indian Mining Conditions.

    Surface Miners have, for sure, saved on cost and wherever they have worked, they have produced desired quality of product by allowing selective mining and more precise mixing of different grades. A high percentage of overall extraction is achieved 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 benches saving 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 without drilling and blasting.

    Ruggedly built sturdy box frame integrated with side plates and lifting jack cylinder to withstand extreme shock loads . Four track steering is provided for efficient steering and control. Height adjustment is electro-hydraulic for achieving fine setting.

    The under-carriage & track assemblies provided are heavy duty type with wider footprint to provide extra tractive effort needed to ensure effortless movement while cutting to the set depth and provide optimized ground pressure for working in soft ground conditions. This ensures greater depth of cut and the rated production and required productivity from the overall system.

    Very robust drum type roll design, wear resistant set with up-milling configuration to achieve uniform depth of cut and near 85-87% -75mm product sizing. The drum is driven by Poly V-belt drive with automatic constant belt tensioning system.
