A Quest for Clean Mixing

From Charles Ross and Son Company
 

 

Mixing is one of the most ubiquitous unit operations in the processing world. And often times, improvements specific to the mixing step lead to overall big rewards that translate well in the balance sheet. The usual challenges include maintaining batch-to-batch uniformity and optimizing blend times, but could be as simple, yet equally important, as improving cleanliness. Below are some ways to lessen the mess and reduce health hazards in your mixing environment, categorized by applications.

In a ribbon, paddle or vertical screw blender operation, sealing arrangements are key to keeping clean. The blender doesn't necessarily have to be vacuum-rated, just dust-tight. Covers with Neoprene or Silicon gasket, clamps, vent ports with dust socks, dust-tight discharge valves, material handling system installed right at the blender's discharge assembly - all these contribute to eliminating fugitive dust issues. In addition, auxiliary dust collection systems and solvent recovery systems (for drying operations) may be used in conjunction with blending equipment.
