How should a feeding system be designed for granular products that tend to bridge?
• Fit hopper with vibrator or pneumatic arch-breaker, pulse every 2-5 min per bridging rate.
• Use hopper cone angle above 60° with PTFE liner to cut wall friction and arching.
• Apply screw feeder with VFD; screw diameter 3-5x particle size to avoid bridging.
• Link level sensor to refill, keep hopper level 30%-70% to prevent compaction bridging.
• Add anti-bridging agitator or vibrating screen at inlet, speed synced to feed cycle time.
