Jinlang Pulp in Guangxi province in the South of China produces eucalyptus pulp. The bulk of production is transported 600 km by truck to the main customer's paper mill. Previ-ously, the pulp was dewatered using a conventional screw press to approximately 25 % dry contents, which entailed high transportation costs. The technology is to be replaced with an AKUPRESS® CX screw press manufactured by Bellmer Kufferath Machinery GmbH, which will increase the dry contents to 40 % and thus reduce the weight to be transported by more than a third. The increase in dry content will be achieved through the patented control system on the AKUPRESS® CX which enables stable operation even at the highest torque levels.
The reduction in transportation costs means the new machine will pay for itself in less than a year. The environmental impact of the process will also be improved, with fewer trucks on the road, resulting in a considerable reduction in CO2 emissions and other exhaust pol-lutants.
