When slurry density influences process performance
Slurry density changes with operating conditions in grinding, classification, flotation and thickening. Periodic sampling can miss the variations between laboratory checks. Alia ADM provides continuous bulk density measurement directly in the pipeline, where process engineers and control systems need reliable information.
What continuous density measurement helps reveal
Changes between samples
Detect density variations that may otherwise go unnoticed between laboratory checks.
Unstable classification
Additional cyclone feed density data to assess operating conditions in the circuit.
Inconsistent thickening
Monitor thickener feed and underflow density trends.
Limited automation data
Provide a continuous signal for trends, alarms and control after integration.
Typical Alia ADM applications in mineral processing
Grinding and classification
Measure density in mill circuits and cyclone feed pipelines.
Flotation
Monitor slurry density at selected feed and transfer points.
Thickening and dewatering
Track density changes in feed and thickener underflow.
Tailings and hydraulic transport
Monitor the density of transported slurry and variations along the line.
How the technology works
Alia ADM uses a mechanical measurement principle based on the dynamic response of a measuring section to controlled excitation. It determines the bulk density of the flowing medium without a radioactive source. The method is designed for industrial slurries, including abrasive mixtures; suitability for each installation is assessed against process conditions.
Other industries where slurry density matters
Mining and mineral processing
Ore slurries, concentrates, tailings and mineral suspensions.
Dredging and hydraulic transport
Sand-water mixtures and transported sediment.

Chemical and power industries
Mineral sludges and process suspensions.
Water and waste treatment
Sludge lines, sediments and slurry transport.
Suitability is reviewed individually, considering medium composition, entrained gas, pipe geometry, temperature, pressure and installation conditions.

A density meter alone does not directly measure mass flow. Flowmeter data and a suitable calculation model are also required.
