STEEL BELT CONVEYORS FOR SEVERE CONDITIONS since 1929

COLACEM

THE CHALLENGE

In the coal storage area there were problems due to the poor dependability and high maintenance costs of the existing rubber belt extractors installed under the hoppers for the coal storage. These hoppers were loaded by trucks with lots of big size coal falling directly on the belt with high impact force. Furthermore, the conveyor also had to work as an extractor from the hopper and the metallic parts, that might be present in the material, would suddenly and frequently cut the belt.

 

THE CUSTOMER

Colacem is an Italian group working in the field of cement. In Italy, its market share has reached around 15% of the national cement production with 1,700 employees. The Company has branches all over Italy with 7 complete cycle plants, one of which is based in Galatina, Southern Italy. The relationships between Colacem and Magaldi dates back to far 1989 when the first Superbelt® conveyor was installed in the Galatina cement factory.

 

THE SOLUTION

The existing rubber belt conveyor had to work as an extractor below the coal hopper. Some foreign pieces (e.g. tramp metals), that might be present in the handled material, would suddenly and frequently cut off the belt. The solution was to replace that rubber belt extractor by a Magaldi “N type” Superbelt®.

The “N type” Superbelt® is a steel belt conveyor made of partially overlapping steel pans bolted on a steel double-wire mesh, that form a virtually sealed belt conveyor. It is used both for horizontal and inclined configuration to convey bulk materials in place of conventional rubber belt or drag chain or vibrating conveyors. The carrying idlers have a closed pitch at the loading point in order to withstand heavy shock and impact loads.
