ALLU PF Pressure Feeder

Mobile binder feeder for dry soil mixing

ALLU PRESSURE FEEDER FEEDS. IT CONTROLS. IT REPORTS WITH PRECISION.

The double tank ALLU Pressure Feeder PF 7+7 NextGen allows for continuous feeding and precise dosing of dry binders, such as lime, cement, fly ash, or other additives in powder form. The PF 7+7 ensures full control over the binder feed which is one of the most important aspects on any soil improvement job-site.

The ALLU PF Pressure Feeder is a self-contained, two-tank, pneumatic 10 bar / 145 psi high air capacity dry binder delivery system. Since time is money, the two-tank configuration makes continuous mixing work possible, because you are feeding the binder from one tank while filling the other. The feeder complies fully with the European Stage V emission standards, which makes it possible to operate on any jobsite.

The computer-controlled feed enables the binder to be added very precisely, which reduces costs and increases quality on the job site. The same computer also provides job-site reporting in either numerical or graphical form.
