This newly patented sampling unit has a wide range of applications in process quality control and waste stream compliance. G.R. Sprenger Engineering has units operating in cement kiln dust, cement clinker, fertilizer, mining slurries and granular materials handling applications. As bulk solids flow down through a vertical pipe or chute, the first stage collects a nominal 2% of the total flow. The second stage repeats this action yielding a nominal 0.04% cut taken continuously from the process stream. The entire process stream flows through the sampler all the time. All material has an equal chance of being sampled. The sample is continuously removed so that the resultant sample is completely representative of the total flow.
Fluctuations of flow do not affect the percent sample fraction collected. Each unit is sized so that the cross sectional flow area is at least twice that of the inlet pipe. The replaceable sample collection chutes have a unique design allowing operation on powders without bridging or plugging.
Dusts, Powders, Granulars, Pellets, Mixed Size Formulations, Slurries.
Sprenger Continuous Samplers are priced competitively. Since there are no moving parts or electronic devices, this sampler is virtually maintenance free. Installation costs are minimal since no electric, pneumatic or hydraulic components are involved.
