Dispersing system

Krima Dispersing System is exclusively designed for dispersing waxes, hot melts, bitumen, stickies, laser ink as well as heavy colours.

The Krima Dispersing system is the most advanced system. Apart from producing the best dispersing result for all kind of dispersable contaminates in waste paper, this is also the most flexible dispersing system.
The discharge side of the screw press does not need to be pressurized as the following plugscrew  is designed to seal the system against the atmosphere. This design allows existing dewatering system to be used.

Sheqar forces introduced to the stock by the plugscrew create a pre-dispersing effect and at the same time an excellent distribution of bleachchemicals when so required.
Retention time of the pulp in the standard design preheater is 2 min. which is enough for reductive bleaching with FAS and a reduction of bacteria and spores in the stock.
