Consistency control runs through the whole stock preparation system, from the pulper to the headbox. This calculator answers the everyday question: how much water do I add to get from this consistency to that one?
It also gives the dry fibre flow, which links the stock system directly to machine production.
Stock & fibre
Dry fibre flow, and the water needed to dilute stock to a target consistency.
Dilution water to add
10,125L/min
Fibre = flow × consistency. Water to add = flow × (current ÷ target − 1). Stock density taken as 1 kg/L.
Production rate
Tonnes per hour, day and shift from machine speed, grammage and trim width.
Reel length and weight
Paper length and weight on a reel from its diameter, core, width and caliper.
Basis weight, bulk and density
Convert grammage to imperial basis weights, and work out bulk and density from caliper.
OEE from shift numbers
Availability, performance, quality and OEE from the figures on a shift report.
FibreMate logs reels and stops as the shift runs and works out production, OEE and lost time for you.
