Just Trays Ltd of Farnley, Leeds (JT) purchased a new casting machine that will enable them to double output of their low profile shower trays. Their previous casting machine included an integral bulk bag unloading hopper. The bag was loaded into place and supported during discharge by an overhead hoist.

The use of dry powdered ingredients can cause a number of problems for producers of ceramic goods.

A reliance on manual handling can cause dust to be released into the atmosphere and operator involvement can be excessive when trying to dose the correct ratios of materials for batch recipes.

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.
