Abstract

A crosscut sampler is particularly useful for obtaining samples of flowing granular or particulate material in a pneumatic conveying system. It has a sample collecting head in a housing connected with the material conveying pipes, the head having a slot-shaped opening extending transversely across the flow passage of granular materials. There is a closure to seal the head and prevent entrance of materials between sampling cycles, the closure for the entrance to the head including a valve element within the head interior and movable into and out of obstructing relation with the entrance to the head, and an air cylinder on the head to operate the closure, the head being mounted on a slide for movement in the housing across the flow passage of flowing materials, and a collecting container to receive the samples from the head.
