Nynas Bitumen UK, part of the Swedish AB Nynas Petroleum company, unlike other oil companies, is a bitumen specialist.

Spiroflow provided the solution for a major chemicals company needing a bulk bag discharger that could overcome a distinct lack of headroom and incorporate a number of customised features to batch silicon carbide into a mixing tank. Spiroflow solved the problem by designing a machine with a special low profile hoist and unloading station operating at a height of only 3.2m, compared to the head room of at least 5m required by most bulk bag dischargers on the market when an integral hoist is included on the machine.

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.
