Cross Stream Cutter.

What’s the benefit

The Cross Stream Cutter is:

  • Theory of Sampling (TOS)-compliant which gives every particle in the stream an equal probability to be included in the extracted increment.
  • Designed to occupy less space, compared to the Cross Stream Sampler (CSS), making it well suited where space constraint is an issue.
  • Equipped with less moving parts compared to other primary samplers.
  • Thanks to a scalable design, the CSC can cope with small as well as high volumes of moving bulk materials.
  • Well suited for harsh environments and rough materials, as commonly seen e.g., in the mining industry.

What does it do?

The Cross Stream Cutter (CSC) is designed to extract a representative increment/cut by discharging a complete cross section of the free-falling bulk material in an outlet chute.

How does it do it?

The CSC consists of a cutter oriented parallel to the moving stream surface. The cutter is attached to a double rail carriage, located above the material flow. The motor control ensures that the cutter operates at a constant speed of up to 0.6 m/s when cutting through the falling material stream. Each time the cutter moves through the stream, from left to right or right to left, an increment is continuously discharged to the outlet chute.


What are the technical details?

The particular design features are decided upon with respect to the specific material characteristics and the stream vectors involved. Considering the extreme density and toughness of some materials, the extraction is recommended as Hardox steel.

The conveyor belt can have a width between 500-2.500 mm.

Housing: Stainless Steel AISI 304/316 or painted carbon steel
Railing system: Stainless Steel AISI 304/316 or painted carbon steel
Carriage: Stainless steel AISI 304/316 or painted carbons steel with Hardox impact plate
Instruments: Inductive Position switches
Gear Motor: SEW or similar

The CSC is delivered with either a local control unit or/and is controlled by a M&W central control cabinet depending on concept and local conditions. The M&W central control cabinet consist of motor control center, circuit breakers, PLC-system, and man-machine interface.


1. The M&W central control cabinet can exchange signals with the client’s control system.

2. The CSC can be delivered with an intermittent sampling option, extracting an increment after each crossing, dependent upon the client’s local setup and needs.
