    CAPACIDAD DE MOLIENDA PARA 1500 TMSD

    1.- MOLIENDA PRIMARIA

    Se tienen las siguientes condiciones:

    Tonelaje alimentado = 62.5 TMH/Hr Densidad de Pulpa = 1870 g/LtF80 = 6595P80 = 879,8

    2.- MOLIENDA SECUNDARIA

    Tonelaje alimentado = 124.5 TMH/Hr Densidad de Pulpa = 1654 g/LtF80 = 629P80 = 414.5

    Mediante las plantillas de Molicop Tools calculamos su capacidad:

    De igual manera con la molienda secundaria

    Se puede concluir que en los clculos no tenemos un factor de seguridad que podraafirmar que si cumplira con el tonelaje deseado, los clculos dan que si se puede

    procesar pero estara al mximo del tonelaje, para ello una correcta clasificacin hara posible esto, se considera que en la molienda secundaria se trabajara con los 3 molinos6 x 6

    2DA POSIBILIDAD: Reemplazo de los 3 molinos 6 x 6 con un 8 x 10
