A manufacturer of pest control products was previously batching a granular pesticide for insect larvae in small quantities using a table-top kitchen mixer. As the product line grew, it became necessary to move the process to a large-scale blender. The company visited the Ross Test & Development Center to see if a Ribbon Blender can produce a uniform blend of the granules, liquid component and powder.
Ribbon Blenders consist of a U-shaped horizontal trough and an agitator made up of inner and outer helical ribbons that are pitched to move material axially and radially. This combination promotes fast and thorough blending even if the batch contains components with different shapes, sizes and densities.
