AnStat-430 Online Sampling and Elemental Analysis Station

The Thermo ScientificTM AnStat-430 online slurry sampling and XRF elemental analysis station is a high availability, low head loss solution for high-quality measurement of critical slurry streams in mineral processing plants without the use of radioisotopes. Featuring the MEP-400 integrated probe for analysis and a representative sampler sized with single or multiple stages to suit your full flow rates, it eliminates the need for pumps and delivers continuous, accurate real-time assays. AnStat-430 enables accurate control of flotation circuits with high reliability and low maintenance.

Key features of the AnStat-430 include:

• Incorporation of the Thermo Scientific™ MEP-400 Multi-Element Probe, which uses advanced X-ray Fluorescence (XRF) technology to deliver safer, more accurate, higher resolution elemental analysis for bulk commodity slurries, relative to the MEP-300 (and all other predecessors).
• Air cooled low power X-ray tube that eliminates any requirement for radioisotopes.
• An advanced, large surface area, energy dispersive Silicon Drift Detector (SDD) for accurate measurement from calcium to uranium with no requirement for cryogenic cooling, for reliable, trouble-free operation over a wide range of in-plant environmental conditions.
• High speed digital pulse processor.
• Very low head loss, simplifying design and layout for sampling while eliminating sample pumps and reducing overall plant head requirements, which optimizes energy usage for the life of the plant.
• Exceptional availability, for reliable accurate measurement and sampling, 24/7.
• Use of one-, two- or three-stage sampling, configured to suit your flowrate, for highly representative proportional stream sampling down to the final stage: an environmentally hardened cross-cut sampler for accurate accounting samples.
• Final stage cross-cut sampler is identical across the full range of process volumetric flows for both the AnStat-430 and Thermo Scientific™ Representative Slurry Sampling Stations.
• Low maintenance, trouble-free operation over the long-term with minimal maintenance, as the only slurry-wetted moving parts are found in the final stage stirrer and cross-cut sampler.
• Simplified integration into existing process plants.
• If you need to measure multiple streams, multiple AnStat-430 units are required, as each unit is designed to handle a single stream.

The AnStat-430 offers a range of additional options, for optimized operation, for each application:

• Pebble screen to reject oversized particles from cyclone overflow for return to the grinding circuit. This option is suggested as a back-up to a primary oversize and tramp material screen located upstream on the primary grinding circuit product.
• Outlet distributor to divide the slurry flow into two or more separate streams of specified flow volume percentage.
• Upwelling/reverse flow sampling zone provides ideal sampling conditions for particle size analysis
• Pneumatic dump valves
• Vacuum Filter for composite (shift) samples
