Screw Sampler

The Screw Sampler is designed to create an average sample from continuous extraction of dry and non-sticky powdered material from a free falling flow of materials.

The continuously operating sampler is driven by a geared motor coupled to a transport screw crossing the flow of material. There are also so many types of samplers used in various industries as per their requirement or feasibility. 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 sampler can be delivered with the drive unit installed next to the mixing tank.

Basic Features

  • Installation in silos or downpipes possible

  • Different diameters for screw samplers available

  • Sample quantities, runtimes and pause times individually adjustable thorough a control electrical panel

  • Automated or manual sampling method

  • Easy-to-dismantle version for simple cleaning

Technical Specification
Types of Operation
Benefits

The sampling screw rotates into the material flow, extracts a representative cross-section from the production flow and transports it into a sample vessel. An adjustable timer determines the sample quantity. Runtimes and pause times between two sampling operations are individually configurable. Before elaborating on the sampling process, the screw changes to reverse operation for a self-cleaning cycle. The product conveyed during the self-cleaning process is fed back into the production flow

The control of the sampler is normally conducted from a central PLC system but we also provide local control panels with or without a PLC

Downpipe: The sampler is installed between two flanges inside the downpipe

Silo: The sampler is installed to a nozzle welded to a silo wall

  • Manually

  • Motorized

  • Contamination-free sampling

  • Low-servicing requirement

  • Size of the sample can be defined as required

  • Immediately after sampling, sample falls into a bag or beaker attached to the discharge connection

  • There is no chance of compact due to mixing chamber is there just after screw for abrasive and sticky material
