Castle Cement has improved control levels, increased production and lowered energy consumption, following the installation of a 620kW Cegelec Alspa GD2000E drive at its cement plant at Stamford, in Lincolnshire.

As part of an upgrade to replace an old damper system, the new drive controls the speed of a 12 blade, 2.8m diameter ID fan, drawing hot air through a cyclone system into an exhaust tower above the mouth of a kiln.

The rotating kiln is fired at 1,400srC, and is fed with a mixture of clay and limestone to produce clinker. Output has now been boosted from 1,000 tonnes per day to up to 1,500 tonnes.
