Screw Samplers

Producers  who are honest about quality of products & serious about firmness of their end product should use Miteck’s Screw sampler .

A Sampling Screw (Auger) Rotates Slowly (A Few Rpm’s) And Continuously Extracts Powder Material From The Sample Process Stream In A Vertical Or Close To Vertical Chute Section. A Mixing Tank – On The Same Axis As The Screw – Collects The Material For A Composite Sample. The Mixing Tank Has Internal Lifters Rotating With The Auger, Which Means That The Sample Material In The Tank At All Times Is A Homogeneous Mix. The Variable Frequency Motor Can Be Adjusted, So That The Time It Takes To Fill The Mixing Tank Is Within ½ To 2 Hour, With ½, 1 Or 2 Hours As The Typical Sampling Intervals.

The Screw Sampler Is Designed For Sample Extraction Of Dry And Non-Sticky Powdered Material From A Duct Or Chute Through Which Free Flow Of Material Is Taking Place.

The Sampler Is Driven By A Geared Motor Coupled To A Transport Screw, Crossing The Flow Of Material. As An Option, The Screw Sampler Can Be Equipped With Variable Speed Geared Motor.

The screw sampler is designed for sample extraction of dry and non-sticky powdered material from a duct or chute through which free flow of material is taking place.

The sampler is driven by a geared motor coupled to a transport screw, crossing the flow of material. As an option, the screw sampler can be equipped with variable speed geared motor.

The screw transports the extracted material to a discharge outlet chute where the material falls by gravity to the subsequent sample preparation equipment.

The screw sampler type size and design is based on chute dimension in mm as well as chute form. It can be mounted in chutes (rectangular or circular)

The control of the sampler is normally conducted from your central PLC system or local control is also possible. It can be equipped with a motion detector as an option.

Manual type Screw Samplers are also available upon request.
