• Powder is metered by weight drop measured in the hopper.
• Water volume is measured by a meter or an electromagnetic flow meter.
• The resulting solution is mixed and transferred to the maturation tank(s) via a dispersing pump.
• PLC cycle control.
• The liquid is dispersed in a special funnel to prevent dry spots.
• The powder for dosing is brought to the funnel by a screw conveyor and a variable-speed drive.
• The powder falls onto the stream of water and is wetted without forming lumps.
• The liquid/powder solution is drawn up into a disperser that has an open turbine to break up or eradicate any lumps that are undesirable in certain solution applications.
• The lifting capacity of the disperser can raise the solution to a height of 10 metres.
• The dry-product storage hopper is vibrated to prevent arching.
