ALLU SOIL IMPROVEMENT SYSTEM

COST EFFECTIVE STABILIZATION AND SOLIDIFICATION OF DREDGED SEDIMENTS

Stabilization and remediation of contaminated materials

ALLU Pressure feeder (PF 7+7) is a soil improvement system designed by ALLU for efficient and effective soil stabilization and treatment. The PF 7+7 combines the capabilities of the ALLU Processor and Pressure Feeder into one integrated system. The PF 7+7 utilizes a combination of ALLU’s proven soil processing and mixing technology to stabilize and improve the quality of various types of soils. It can handle different soil conditions, including clay, silt, sand, dry and wet soil.

ALLU Pressure Feeder component of the PF 7+7 allows for continuous feeding and precise dosing of binder materials, such as lime, cement, or other additives. This ensures even distribution and thorough mixing of the binder with the soil for effective stabilization.

The PF 7+7 is suitable for a range of soil improvement applications, including road construction, building foundations, embankments, and other infrastructure projects. It offers the versatility to adapt to different soil types and project requirements. The integrated system of the PF 7+7 enables efficient and high-speed processing of soils. It ensures thorough mixing and stabilization while optimizing productivity and project timelines.

Operators can customize the mixing recipes of the PF 7+7 to meet specific project needs. Adjustments can be made to the dosage and type of binder materials, allowing for tailored soil stabilization results. ALLU PF 7+7 system improves productivity and can lead to cost savings. It minimizes the need for extensive excavation and replacement of poor-quality soil, reducing material and transportation costs while optimizing project timelines.

ALLU PROCESSOR

The ALLU Processor is a power mixer attachment for conventional excavators. This attachment converts the excavator into a powerful and versatile mixing tool capable of penetrating and effectively mixing a variety of difficult materials – everything from clay, silt, peat, sludge and sediment, to dredged material and contaminated soil.

ALLU Processor is a versatile attachment designed for material processing, screening, and soil improvement applications. It is compatible with excavators, loaders, and other earth-moving machinery, providing a range of functionalities to enhance various industries’ operations.

ALLU Processors can process and homogenize materials, ensuring even distribution and mixing of different materials and additives, such as lime, cement, or other binders. It enhances the properties of the materials for specific applications. ALLU Processor is capable of soil stabilization and treatment. It can mix and stabilize different soil types, improving their load-bearing capacity, stability, and other desired properties.

ALLU PF PRESSURE FEEDERS

The ALLU PF Pressure Feeder is a self-contained, two-tank, pneumatic-based dry binder delivery system.

It uses an on-board air compressor to pressurize a tank of binder and deliver it in dry form. Delivering and mixing binder in dry form conserves the “drying” capacity of a binder. It’s a highly cost-effective solution when wet soil or sediment needs to be stabilized.

The computer-controlled feed enables the binder to be added precisely, which reduces costs and increases quality on the jobsite.

PF 7 + 7 MOBILE FEEDER FOR DEEP DRY MIXING

LIME/CEMENT COLUMNS.

The ALLU PF 7+7 is a self contained mobile feeder for deep dry mixing, the track driven feeder is completely road legal and easy to transport on a low bed trailer making it extremely mobile. Fast setup on jobsite results in less down-time and the large air capacity gives improved productivity.
