  • Savings in coal mining | PR | Wirtgen

    Wirtgen surface miners can cut, crush and directly load material onto trucks or dumpers in a single operation. This saves time and the additional cost of purchasing machinery and fuel. Working with the 4200 SM in the Australian mine resulted in a 79% reduction in fuel consumption per cubic meter of mined material. Labor costs were reduced by 60% and mining unit costs per ton were reduced by 60

  • DESIGN AND ANALYSIS OF A HORIZONTAL SHAFT IMPACT CRUSHER

    This type of crusher is generally used with soft materials like coal, seeds or soft metallic ores. The mechanism applied here is of Impact loading where the time of application of force is less than the natural frequency of vibration of the body. Since the hammers/blow bars are rotating at a very high speed, the time for which the particles come in contact with the hammers is very small, hence

  • Coal | McLanahan

    McLanahan crushers can take the coal producer through all stages of crushing process, from initial reduction in the primary stage to further reduction and refinement in the secondary and tertiary stages, all while minimizing the generation of dust and fines. Employing the basic reduction principles, McLanahan crushers reduce coal at maximum volume using compression, impact, attrition and shear forces. Crushers engineered by McLanahan consume less power and are able to reduce coal

  • CASE HISTORY: AGGLOMERATION OF COAL FINES AT A FOSSIL

    First attempts involved blending the coal fines with the crushed coal on the conveyors that feed the coal bunkers. This created a dust problem at the bunker as well as problems in blending the coal on the conveyor. To arrive at a solution to the fine dust handling problem, three methods were considered and evaluated. The first method was to pneumatically convey the fines from the baghouse to the bunker
