AJF recycling screws are available in two sizes. Here we offer a cost-effective yet highly efficient recycling system for small quantities of return concrete.
Compact and economical design
Robust, fully galvanised model with centralised lubrication of the lower worm gear bearing.
Optional bucket wheel for recovering concrete returning from concrete pumps or wheelbarrows
Advantages of the recycling screw
Space-saving installation
Reliable operation even in winter
Automatic lubrication and optional heating
Energy efficient
High flexibility – also for concrete pumps
The recycling screw can be combined with a scoop wheel as an option. The scoop wheel conveys fresh concrete from a feed table embedded in the ground into the screw. Concrete applied close to the ground can be easily integrated into the regular washing process, eliminating the need for rotating parts or bearings in the ground.
Low maintenance and durable
The special arrangement of the screw flights at a fixed distance ensures the formation of a protective material bed, which significantly reduces wear and minimizes maintenance. The hot-dip galvanized trough also guarantees a very long service life.
Efficient in operation
The cleverly designed feed hopper allows loading from different directions – even with one or two truck mixers at the same time. Its geometry provides reliable protection against overfilling. Thanks to the increased discharge height, generous material storage is possible. The separation accuracy remains constant at a maximum of 0.25 mm.

MEASURABLE BENEFITS
The recycling of fresh concrete affects both precast plants and ready-mix concrete manufacturers. In both cases, excess fresh concrete can be broken down into its components: gravel, sand, and residual concrete water.This process offers your company significant advantages:
Savings on disposal costs
for concrete slurry when using settling tanks
Compliance with legal environmental regulations
through closed-loop recycling
Resource conservation and cost savings
CO₂ reduction
