allmineral – allflux® – sustainable and effective | allmineral Aufbereitungstechnik GmbH & Co. KG

The allflux^® procedure uses fluidised bed technology for density sorting and hydraulic classification. This two-stage treatment makes it possible to process a mixture of sand and water without pre-thickening. An upflow that passes through the feed slurry at the coarse sand level causes the light and fine particles to rise up, with the sinking coarse and heavy particles being removed.

The fine sand level, a circular process that constitutes the second stage, is reached by the light material – including the fine particles that form an autogenous fluidised bed. The light material awaiting separation floats on this bed and subsequently spills over with the upflow of water.

Sorting, classification, thickening and cleaning all performed in a single unit
Production of quality sand from deposits featuring impurities
Consistent material quality via automatic process control
Low energy requirement and low wear

Wet processing & sand classification with allflux®

The allflux® fluidized bed system enables efficient wet processing and classification of sand and mineral raw materials. By combining advanced control software with optimized process technology, organic contaminants can be reliably removed while precisely classified sand fractions are produced. This allows even contaminated or mixed material streams to be processed into high-quality sand products, while maintaining low capital and operating costs.

The allflux® system is used across a wide range of applications in raw material processing. Typical fields of application include the sand and concrete industry, fine coal recovery, ore processing, mineral sand processing, as well as the recovery of glass and sand from waste streams. This versatility makes the system suitable for both primary and secondary raw materials.

A key advantage of the allflux® technology is the integration of multiple process steps within a single unit. This significantly simplifies process flows and reduces the need for additional equipment such as cyclones, classifiers, or thickeners. As a result, both capital investment and operating costs can be reduced. At the same time, the compact design of the system allows for high performance within a limited installation space, while ensuring stable process conditions and consistent product quality.
