Radiscreen-K™ Knotter Screen

Efficiently separates knots, uncooked wood chips, and other coarse contaminants in unbleached chemical pulp mill systems.

Radiscreen-C™ Coarse Screen

Radiscreen-K knotter screen serves as an efficient screen for gentle removal of knots, which prevents the generation of shives and ensures the lowest possible fiber content in the reject. The Radiscreen-K knotter screen’s stable operation and high energy efficiency is achieved through the radially increasing peripheral velocity of the rotor vanes. As a result, the rotor speed can be kept low, which leads to exceptionally low power consumption.

Designed for high hydraulic capacity, the Radiscreen-K provides stable operation, high runnability, and maximum availability at high flow rates, even under upset conditions when the knot content may be much higher than normal. The low reject rates by mass ensure low fiber content on the rejected knots.

Radiscreen-K knotter screening systems can be installed with practically any type of washing equipment, such as wash presses, DD washers, Chemi-washers, and vacuum washers.
