Savings in downtime and material costs plus improved, faster production have been achieved by Colfix at its Dublin bitumen processing plant by replacing a manually-fed rigid screw conveyor with a Spiroflow bulk bag handling system. The new equipment comprises a Spiroflow Type 2 bulk bag discharger and a Type 5 low loading bulk bag discharger, each having a 2m Model 120 flexible screw conveyor which meters product to a 50 litre transition hopper.
