METHOD FOR SUPPLYING LUBRICANT USED FOR PELLETING, AND APPARATUS THEREFOR

摘要

PROBLEM TO BE SOLVED: To reduce a cost of a facility for mixing a powder and a lubricant; to form a pellet having high purity and improved hardness and density; and to remarkably reduce the consumption of the lubricant. SOLUTION: A method for supplying the lubricant comprises converting the lubricant to be applied onto a die 14 into a misty state, naturally or forcefully attaching and applying the lubricant supplied from a charging line 4 onto an inner wall of the die 14, and discharging a surplus misty lubricant (b) before charging powder (a). The supplying apparatus comprises an atomizer 1 for converting the lubricant into a misty state; the charging line 4 for introducing the misty lubricant (b) sprayed from the atomizer 1 to the die 14 through a charging valve 2; a discharging line 8 for discharging the misty surplus lubricant (b) supplied to the die 14 through a discharging valve 7; and an aspirator 9 for sucking the misty lubricant (b) in the charging line 4 and the discharging line 8 so that the misty lubricant (b) passing through the charging line 4 can be naturally attached or forcibly applied onto the inner wall of the die 14.
