Filtration system for the cooling water at the roll mill

BOLLFILTERs help to reduce the high maintenance and downtime cost by preventing the spray nozzle blockages of cooling water sytsems.

Reference for cooling water filtration in the steel industry

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 Type 6.18, 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.
