Meaning
Bulk storage engineering ensures that every particle of resin moves toward the outlet at the same velocity regardless of its position in the bin. Mass flow silo design prevents the formation of stagnant zones or ratholes that lead to material spoilage. This flow regime depends on the steepness of the hopper angle and the smoothness of the interior walls.
Discharge Pattern
First in first out delivery maintains the chronological integrity of resin batches during large scale production. Using a mass flow silo eliminates the risk of old material remaining trapped in the vessel for extended periods. This consistency is necessary for maintaining steady color and moisture levels in the feed.
Resin Segregation
Particle size distribution remains uniform because the material does not separate by density or shape during emptying. A mass flow silo reduces the tendency of fines to accumulate at the center or the periphery of the vessel. Homogeneous material flow ensures that the extruder feed throat receives a consistent blend.
Wall Friction
Pressure distribution across the hopper walls is higher than in vessels with funnel flow characteristics. The construction of a mass flow silo must account for these increased loads to prevent structural deformation. Reliable discharge is achieved by matching the hopper geometry to the specific frictional properties of the polymer pellets.
