Solids analyzer PERI™

liquidsprocessmonitoring

Overview
The PERI™ online slurry analysis system provides fast, configurable elemental analysis for mineral processing plants. Using solid-state energy dispersive X-ray fluorescence (EDXRF) with a high-rate silicon drift detector, the system delivers elemental concentrations for multiple process streams and integrates with standard slurry sampling equipment.

Key features and benefits

• Fast analysis of multiple streams: high-rate SDD for rapid measurement of low concentrations; supports multiplexing (single multiplexer supports up to six streams; add additional multiplexers to expand capacity).
• Low operational cost: low-power x-ray tube operated below rated power to extend life; thermoelectric detector cooling; minimal routine maintenance with replaceable sample windows and robust stainless-steel enclosure designed for wash-down environments.
• Advanced solid-state technology: EDXRF detector with no liquid nitrogen or radioisotopes required, enabling continuous on-stream operation and simplified maintenance.

System capabilities and applications
The PERI™ system measures elemental concentrations across a wide range of process streams — from tailings to matte — and can replace multiple point analysers. It is proven in base-metal concentrators such as copper, lead–zinc and molybdenum plants. Element channels are configurable and the unit can detect and alarm on sample flow issues. Typical measuring times are 15–90 seconds depending on element and stream conditions.

Accessories and sample handling

• Compatible with primary and secondary slurry samplers and standard sample handling equipment.
• Examples: Essa® slurry samplers, multiplexers, composite samplers, calibration samplers, de-multiplexers and vacuum batch filters.

Maintenance & service
Support options include design and selection guidance, onsite supervision for installation, commissioning and calibration, operator training, scheduled maintenance visits and remote off-site support.
