Flat disc refiner
The Flat Disc Refiner is a refiner of single-disc cantilever design with hydraulic positioning of the rotor disc and the front cover supporting the non-rotating stator disc.

Presteaming bin
Presteaming softens the raw material before the screw feeder and makes it easier to compress, thus improving the dewatering capability and decreasing the wear of the screw feeder.
Pulp
Impregnator
The sudden expansion of the chips in the impregnator enables the chips to instantly soak up the impregnation chemicals provided to the impregnator.

Valmet TwinRoll press
Valmet's TwinRoll presses are characterized by excellent washing efficiency, high availability and high output consistency. They also have very high specific capacity resulting in extremely compact installations, which make the TwinRoll presses especially suitable for upgrades.

Screw drainer
A screw drainer is designed to drain the circulating wash water from the washed chips prior to entering the impregnation or primary refining system.

Pumps
Valmet’s unique and wide range of medium consistency pumps enables the most energy and cost-efficient pump choice for each application. The selection consists of two types of pumps: the CM type for feeding bleaching stages and reactors, and the CW type for feeding presses.

Liquor filter
The Valmet Liquor Filter effectively separates fibers from the spent liquor. All recovered fiber is returned to the pulping line for additional gain. An investment of a Liquor Filter will reduce fiber loss and ensure continuous economical operation for your evaporators.

Bleaching of chemical pulp
The key success factors in bleaching chemical pulp are effective mixing of bleaching chemicals into the pulp, well-defined retention times in bleaching reactors and barrier washing between bleaching stages. Barrier washing results in low chemical consumption, low effluent flows and the possibility to operate at zero fresh water consumption.
