How can I prevent material buildup or bridging when conveying plastic resins?

Material buildup and flow issues like bridging can happen when plastic resins flow through the system too quickly, or when your equipment lacks the proper accessories to handle flow issues. Ensure rotary valves are properly sized for your material, system, and desired rate of flow, and consider accessories such as shear protectors and air purge kits to prevent issues such as shearing, jamming, and buildup.
