Sandtoft cuts wastage with Eriez

27 August 2009

Sandtoft has cut production wastage at its Broomfleet Tileworks, East Yorkshire, UK with vibratory feeders from Eriez. The model HC36 high control vibratory feeders, positioned above the conveyors, distribute a thin, even layer of sand onto the roof tiles in the processing line at a rate of 150kg per hour.

The electro-magnetically driven HC36 feeders incorporate an energy-efficient AC drive and are claimed to offer low power consumption. The High Control range has precision variable (0-100 per cent) control.

During the Sandtoft trials each feeder was supplied with a stainless steel tray measuring 250mm (width) by 610mm (length), a hopper through which the material is collected and fed and a variable speed control. The special design of the drive ensures an even spread of the process material.

Eriez tested sand samples in the laboratory at its European headquarters in Caerphilly, South Wales. The company claims the tests yielded impressive results and proved that it was possible to feed a very thin layer of sand onto the tile surface. This cut product wastage and, in turn, reduced manufacturing cost.
