ST Macchine high density pulpers, with an operating consistency of 12 to 18%, are suitable for the defibering of all types of waste furnish and virgin pulp offering the following main advantages:
Less space requirements.
Due to an high consistency operation there is an higher friction among the fibers that helps the detachment of ink particles from the fibers.
No breaking up of contaminants because of low peripheral speed of rotor and so easier removal of contraries from the stock.
Lower energy consumption.
Lower consumption of steam (optional) and chemicals (optional).
