Falling Stream Sampling Systems

Falling Stream Samplers are a general product category that covers a wide range of sampler designs. The key characteristic all these designs have in common is that sample material is collected from a main process flow that is either in a free-falling condition or traveling through some trajectory, such as at the discharge of a conveyor. Falling Stream Samplers tend to be simpler in design and function, and usually offer highly reliable operation with relatively low maintenance requirements. This style of sampling is well suited to high flow rate applications where minimal downtime is a requirement, such as loadout systems.

Using a Falling Stream Sampler does have some limitations. This type of sampler requires some amount of vertical clearance for installation (this height varies by machine type and application), and they are sometimes more invasive and expensive to install. There are many applications for Falling Stream Samplers. McLanahan has a range of product offerings, as well as the ability to develop custom designed Falling Stream Samplers, to meet the needs of your specific requirements.

Popular Applications for Falling Stream Sampling Systems

Falling Stream Samplers can be widely applied throughout many industries. Essentially, as long as sufficient vertical height and clearance around the sampling area exists, a sampler can be installed. Materials that are commonly sampled include coal, coke, crushed ore, concentrates, potash, sand, stone, gravel, salt, bauxite, wood pellets and any other materials that are typically handled in bulk material handling facilities.

Frequently Asked Questions

What other technologies should I consider?

If one of the various Falling Stream Sampler options is not well suited to a particular application, a Cross Belt Sampler could be used. If the application in question is related to sampling from trucks, railcars, or stationary lots, Auger Sampling Systems could also be considered.
