BOLLFILTERs like the aquaBoll® help to reduce the high maintenance and downtime cost by preventing the spray nozzle blockages of cooling water sytsems.
The mill from Thamesteel in Sheerness, a specialist manufacturer of steel products mainly derived from recycled scrap metal, uses continuous cooling water to keep the bar at the correct temperature and prevent roll breakages.
A BOLLFILTER Automatic was installed by the cooling water system at the roll mill. The system incorporates a pre-screening basket strainer linked to the Self-Cleaning BOLLFILTER Automatic, with all functions controlled by a microprocessor control panel. Operating at 1363m3/hr (at a maximum 16 bar) with a filtration level of 500 microns, the unit provides a total filtration area of 57320 cm2 by means of 40 high precision slot screen elements.
