Screw Sampler

The screw sampler is designed to create a sample from continuous extraction of dry, non-sticky free flowing materials. A geared motor coupled to a screw crossing the flow of material drives the continuously operating sampler. The screw transports the extracted material to a mixing tank where it is homogenized by mixer wings connected to the through going screw conveyor shaft. The material at any time present in the mixer tank will represent a true average of the material having passed the sampler. The mixing tank has an overflow to safeguard against overfilling. Excess sample material is returned to the main material stream by gravity.
