Collection of samples from a conveyor transfer duct
The device for taking representative samples of bulk materials (powders, dusts, granulates and aggregates) from the transfer channels is an element of the WOLFF GROUP offer. The offered samplers can be mounted on ducts and gutters where the product is transported by gravity. Solutions provided by our company are characterized by solid workmanship, precision of operation and reliability.

We will answer questions about: offer, technical specification, delivery, assembly.
