The supply of the five AUMUND Pan Conveyors was part of Cementownia Warta’s project to build a steel-roofed concrete silo designed to hold 120 000 t of clinker. Silo feeding is carried out by an AUMUND Pan Conveyor with a centre distance of 145 m and a capacity of 500 tph. Discharge is by three Pan Conveyors, one of which has a capacity of 600 tph, and the others 300 tph each. These three Pan Conveyors, type KZB, transport the clinker to a 600 tph Pan Conveyor which operates as a collector and takes the clinker on to feed the mill. The connection of the silo to the clinker production process is assured by a Pivoting Pan Conveyor with a centre distance of 78 m and a capacity of 474 tph, which was originally supplied by AUMUND back in 2008 to feed eight smaller clinker silos.
As part of the project to construct the 120 000 t clinker silo, AUMUND planned the clinker conveying circuit for silo feeding so that a second, identical silo could be connected at a later stage without having to make any significant modifications to the existing plant layout. Space has been left in the bridge to the future silo to install a further Pan Conveyor to feed the second clinker silo.
