SamStat-30 Representative Slurry Sampling Stations, SamStat-20 Slurry Sampling Station - FAQs

When selecting a representative slurry sampling system, consider the process flow rate, slurry characteristics, sampling objective, available head, plant layout, maintenance requirements, and whether samples will be used for metallurgical balancing or online process analysis. Requirements for particle size measurement, elemental analysis, oversized-particle removal, and slurry distribution should also be evaluated. For greenfield plants, defining sampling and analysis requirements early in the design process can help teams evaluate equipment layout and construction considerations.

The appropriate Thermo Scientific SamStat-30 options depend on your process stream and how the representative sample will be used. Consider these application requirements when configuring your sampling station:

• Multi-stage modular design: whether your flowrate is 4 m³/hr, 36,000 m³/hr or anywhere in between, SamStat-30 is configured to suit your application.
• Composite sample collection: SamStat-30 provides high integrity composite samples.
• Online analysis: if representative slurry needs to feed an online analyzer, select the appropriate integrated-analysis configuration based on the measurement required. For example, the SamStat-30C provides a continuous representative slurry flow suitable for online elemental analysis. A SamStat-30 can be upgraded later to incorporate online analysis, making it an AnStat-430, but a SamStat-30C or SamStat-30R cannot.
• Composite sample processing: if composite samples need to be prepared for subsequent analysis, an automated vacuum filtration system can be incorporated into the sampling configuration.
• Multiple slurry streams: if the sampled slurry needs to be divided between multiple downstream streams, an outlet distributor can split the flow into two or more streams at specified proportions.
• Oversized particles: if the slurry contains oversized material that needs to be removed, consider a pebble screen to reject oversized particles from the process stream.
• Particle-size analysis: if representative slurry is required for online particle-size measurement, consider a reverse-flow sampling configuration, such as the SamStat-30R, which provides a suitable sampling zone for PSM-500 particle-size analyzer.

The Thermo Scientific SamStat-30 Slurry Sampling Station has few moving and wear parts, with moving components concentrated in the final stage cross-cut sampling system. Static polyurethane cutters are replaceable (in certain cases without stopping slurry flow), and the open layout supports access for inspection, cleaning, and performance monitoring. These design features can help simplify routine maintenance and should be considered alongside the plant’s availability and maintenance requirements. The basic SamStat-30C and SamStat-30R have no moving parts. Optional VacFilt automatically filters SamStat-30 shift composite samples, saving time, labour and manual handling. Optional pneumatic dump valves reduce effort and simplify maintenance shuts.

Yes. The Thermo Scientific SamStat-30 Slurry Sampling Station can be configured to provide representative slurry samples for online process analysis. The SamStat-30C generates a continuous representative flow that can gravity feed nearby online elemental analyzers such as the Thermo Scientific MSA-430 and GS Omni. A dedicated multi-element immersion probe can also be integrated into the final sampling stage, creating the Thermo Scientific AnStat-430 integrated sampling and analysis station. Reverse-flow configurations can support online particle size measurement with the Thermo Scientific PSM-500.

The Thermo Scientific SamStat-30 Slurry Sampling Station can be configured according to the required process flow rate and application. Available configurations include different tank sizes, one-to-four-stage sampling arrangements, single or multiple inlets, and different inlet and outlet locations. Additional options include oversized-particle screening, slurry distribution, reverse-flow sampling for particle size measurement, pneumatic dump valves, and automated composite sample filtration. This flexibility allows the sampling station to be configured based on specific process and plant-layout requirements.

The very low-head design of the Thermo Scientific SamStat-30 Slurry Sampling Station can help reduce the elevation required for a representative sampling system. Its sampling stages are arranged at a single floor level, which may help reduce the need for tall sampling structures depending on the plant design and subsequently save or even eliminate the need for pumping. For greenfield projects, considering sampling requirements early in plant design can help teams design with potential layout and construction advantages.

Representative slurry sampling is important because the quality of the sample directly affects the reliability of metallurgical balance, process control, and online analyzer calibration. A sample that does not accurately represent the full process stream can introduce sampling and measurement errors that affect operational decisions. The Thermo Scientific SamStat-30 Slurry Sampling Station is designed to reliably provide high integrity proportional, representative samples of critical mineral slurry streams to support process monitoring, metallurgical balancing, and analysis.

The Thermo Scientific SamStat-30 family can be configured for different sampling and analysis requirements. The standard Thermo Scientific SamStat-30 Slurry Sampling Station produces representative composite samples for metallurgical balancing. The Thermo Scientific SamStat-30C Continuous-Flow Sampling Station generates a continuous representative slurry flow for online elemental analysis with systems such as the Thermo Scientific MSA-430 and GS Omni. The Thermo Scientific SamStat-30R Reverse-Flow Sampling Station generates a representative flow for online particle size measurement with the Thermo Scientific Particle Size Analyzer PSM-500. The appropriate configuration depends on the measurement and sampling objectives of the plant.

The Thermo Scientific SamStat-30 Slurry Sampling Station uses a multistage, full-flow sampling approach to progressively subsample the slurry stream. Depending on the required process flow rate, the system can incorporate one to three stages with appropriately sized tanks and static cutters. A final stage then uses an environmentally hardened cross-cut sampler to produce composite samples for metallurgical balancing. This proportional, multistage approach is designed to provide a representative sample of the process stream for metallurgical balancing, process monitoring, and analysis.

Consider the Thermo Scientific SamStat-30 sampling station when you need high integrity representative slurry samples for metallurgical balancing, process monitoring, or online analysis in a mineral processing plant. Its multistage, full-flow sampling approach is designed to progressively subsample large process streams while maintaining sample representativeness. Its modular design works with flowrates from 4 m³/hr to 36,000 m³/hr. The SamStat-30 is well-suited to applications where low head-loss, flexible plant layout, high equipment availability, and integration with online elemental or particle size analyzers are important considerations.

Yes, with a new site, you have a one-off opportunity to integrate analysis and more specifically sampling from the outset. To make the most of this opportunity, start considering sampling and analysis early in the design process, not towards the end, as an add on. A defining advantage of our samplers is low head. By delivering multiple sampling stages at one floor level, they can lower plant elevations and eliminate any need for sampling towers. This can have a major impact on construction costs.
