Van Beek, Drunen, the Netherlands, reports that it is vital that the sludge drying plant operated by Hollands Noorderkwartier District Water Board (HHNK) should not be shut down for a lengthy period. Clear agreements have been reached with Van Beek to prevent this happening. Meanwhile the plant has already been operating at full speed for five years.

 

Peter van der Stoop, technical assistant at HHNK, is fully satisfied with the service provision that accompanies the contract. "I think our cooperation with Van Beek is very good, in case of problems they take appropriate action and the regular servicing is carried out to our satisfaction."

 

The plant incorporates eight Van Beek and Celsius screw conveyors. There are two identical lines each with a cooling screw with twin screws and three screw conveyors. Dried hot sludge granules are brought in by the cooling screws. After cooling, the screw conveyors transfer the granules to a silo. Cooling prevents over-heating inside the silo.

"The HHNK wanted to be sure that the plant would continue operating ", said Téan van Horssen, service and after sales assistant with Van Beek."If our screws stop, the whole plant stops because the granules cannot be stored safely. It was no problem for us to give this guarantee. We know our machines and we know how they perform." 

 

The service contract states when the bearings have to be replaced and when servicing needs to be carried out. "This gives the client assurance and it is clear beforehand what costs we can expect ", explained Van Horssen. The contract also states the minimum number of hours the plant should operate annually. Van Beek welcomes the opportunity to enter into similar contracts with users of its screw conveyors. www.van-beek.nl
