H+H Siporex is a leading producer of aircrete in Northern Europe and the UK
The key raw materials of Autoclaved
Areated Concrete (AAC) are lime and quartz sand. Incorporating a new operating principle, the robust LPP65 and LPP40 pumps
have provided H+H Siporex with a perfect solution for their demanding and abrasive slurry duty.
Together with furnace slurry, the raw
materials of AAC are fed to a ball mill prior to being mixed together in reactors. From these reactors the abrasive slurry
mixture is then pumped to a storage tank for further processing
The pumping of this slurry is a demanding task. Previously used and tested conventional hose and centrifugal pumps
proved unsuccessful resulting in high maintenance costs, reduced maintenance intervals and frequent bearing repair.
Ball mill discharge flow pump in this application, the LPP65 pump normally operates
from 20 to 22 hours per day 5 days a week with a pumping speed of 36 rpm and a flow rate of 11.5. m3/h at 3 bar
pressure
The LPP65 pump is equipped with a 5.5. kW motor and a hose leak detector that will give an early warning
of any hose leakage.
