AUMUND Fördertechnik, Rheinberg, Germany, has to date supplied more than 20 heavy-duty materials handling machines to the central Poland plant of cement manufacturer Cementownia Warta. The bulk handling equipment manufacturer has been working continuously with the customer to develop further systems, including five pan conveyors type KZB. Since these were commissioned last year (see EBS News for week of 23 September 2019), they have been operating with such remarkable reliability that in mid-2020 Cementownia Warta ordered a further arched plate conveyor type BPB-SF in heavy-duty design. This conveyor is to be supplied before the end of the year, for a new limestone crushing facility.

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 120,000t of clinker. Silo feeding is carried out by an AUMUND pan conveyor with a centre distance of 145m and a capacity of 500t/h. Discharge is by three pan conveyors, one of which has a capacity of 600t/h, and the others 300t/h each. These three pan conveyors type KZB transport the clinker to a 600t/h 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 78m and a capacity of 474t/h, which was originally supplied by AUMUND back in 2008 to feed eight smaller clinker silos.

As part of the project to construct the 120,000t capacity clinker silo, AUMUND planned the clinker conveying circuit for silo feeding so that a second, identical silo can 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. www.aumund.com
