Cross-Belt Sampler

The Cross-Belt Sampler is the new and improved hammer sampler. It is designed to take an increment/cut from bulk materials being conveyed on a conveyor belt. It includes a fully enclosed housing that covers all moving parts thereby reducing spillage and increasing safety.

The Cross-Belt Sampler (CBS):

• Is a cost-effective sampling solution.
• Can be customized to the client’s specific installation and material.
• Is easy to install almost anywhere along a conveyor belt.
• Is well suited as a retrofit sampler/ can be integrated on existing conveyor belts.
• Eliminates the need for hazardous and manual grab sampling and increases employee safety.
• Saves time and money allowing for sampling without belt stoppage.
• Can be modified to remove identified unwanted magnetic/metallic material from the conveyor belt.
• Meets ISO, ASTM & GOST standards.

The sampler consists of a rotating counter-weighted sample cutter which moves in a 360-degree motion perpendicular to the material direction. The sample cutter is driven by a gear brake motor and a guiding section supports the conveyor belt. The cover housing is equipped with hatches allowing easy inspection, cleaning, and maintenance.

When automatically or manually triggered, the sample cutter is accelerated by the electric motor to the designated velocity. It cuts through the material stream on the conveyor belt in a circular motion, following the supported shape of the belt. The conveyer belt is supported and guided by a pair of inclined rollers or guiding plates which ensure that the sample cutter remains in maximal contact with the belt throughout the entire cut. Furthermore, a flexible scraper is installed to ensure collection of all fines material.

The increments are then delivered to sample containers or to optional secondary sub-systems. After leaving the cut zone, the sample cutter is slowed down to allow the collected increment to fall into the outlet chute. Internally located skirts after the cut zone close the gap to the conveyor belt to prevent spillages.
