01/01/2015· CONCLUSIONS Expert systems have proved to be the most flexible tool to control the performance of an industrial thickener. This approach can lead with hard variable constraints to avoid emergencies without the need of a reliable thickener model. However, the implementation of the logic rules has to consider the process dynamics in order to keep a smooth operation without the risk of .
drive system of a thickener automatic molino. Thickening Resource Book. The drive assembly is the key component of a thickener. The drive assembly provides: • The force to move the rakes through the thickened pulp and move settled solids to the point of discharge. • The support mechanism which permits it to rotate. • Adequate reserve capacity to withstand upsets and temporary overloads ...

The performance of the gravity drum thickener is based on 50 years of pulp dewatering experience. The Drum Thickener PRS is a simple, cost efficient, and reliable filter for dewatering stock and broke ( and recycled fibers) in a consistency range of –%. Features and benefits of the ANDRITZ Drum Thickener PRS
Gravity is utilized to thicken the sludge from a feed consistency of –5% to a discharge consistency of 12–22%. The gentle treatment of the gravity table keeps the flocculent consumption low and results in a lower filtrate load compared to other predewatering systems.
