HD Cleaners

 

With the increasing popularity of medium consistency screens with small holes and with fine slots, HD cleaners provide protection against rapid wear of the baskets. As they eliminate heavy and highly abrasive particles, they are also essential for the protection of other rotating equipment, including pumps.

 

Working Principle

Stock is introduced tangentially at high speed in the upper part of the HD cleaner at medium consistency (from 3% to 5%). The main flow is attracted by the central vortex whereas heavy particles are centrifuged until they reach the lower part of the cleaner. A counter pressure flow with whitewater is generally introduced to create a perfect separation of these heavy contaminants and the remaining fibres to produce a fiber-free reject.

 

HD Cleaners are fully automatic and can be installed as one-stage (discontinuous) or two-stage (with first stage continuous).

 

Applications

Primary and secondary fiber lines.
