Consistency varying
1. Mills should have double stock regulation so that consistency changes do not affect the quality of the stock fed to machine. — the proportions of stocks should not vary if the consistency to the proportioning system is constant for each stock component. 2. Where consistency to regulators varies by such an amount that the […]
Repulper (hydropulper) operations
Influence of circulation rate or agitation: 1. The speed of developing a slurry (defibering) is roughly proportional to the intensity of the mechanical action. 2. This agitation or turbulence requirement is fundamental to repulping. — pulper operating with poor circulation is usually unsatisfactory for anything. 3. If broke or wastepaper is to be slurried, the […]
