To summarize the coal mill controls they may be divided basically into two major categories 1 To control the quality of coal being sent to the burners located on the furnace walls The word quality here means the temperature and fineness of the PF The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel
mills in the older plants that had many mills in parallel In fact this is generally still the case in the multi stream plants where mill liner design and selection is only tackled on a cost consumables basis However the gains to be had through good liner design and selection are just as great as on the large SAG mills
Beyond Mine to MillCircuit Design for Energy Efficient Resource Utilisation use it wisely and optimally Societal pressure is enforcing this and the SAG mill Since that approach was developed new drivers have risen to prominence including environmental costs and impact of energy water waste is pushing up our impact on the environment
The Buenavista unit operates a leaching facility and three SX EW plants All copper ore with a grade lower than the mill cut off grade of 0 38 but higher than 0 25 is delivered to the leach dumps A cycle of leaching and resting occurs for approximately five years in the run of mine
