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

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
