Case Study: Separating Large and Small Rocks in Gravel

A customer in the construction industry was working with gravel consisting of rocks of varying sizes, which needed to be separated into groups of large and small rocks while conveying the gravel from one station in the process to the next.

The customer purchased a closed trough and sieve with dual outlets, one for larger rocks and one for smaller rocks. The sieve is driven by a MARTIN® NTK® 85 NF Pneumatic Linear Vibrator connected via FlexiLink. During processing, the smaller rocks fell through the openings of the sieve and were conveyed through one outlet, while the larger rocks stayed on top of the mesh and were conveyed through the other outlet.
