Food & BeverageBrazil· ZPS Straight-Through Screen
Pre-packing scalping at 5.2 t/h — zero filler stoppages in 14 months
- The problem
- The mill packed 25 kg bags at 5 t/h, but occasional wheat-fragment and bag-nip oversize jammed the filler head, stopping the line 2–3 times a week for manual clearing and metal-detector re-validation.
- Original process
- Screw conveyor fed the filler surge hopper directly — no guard screen between reception silo and packing.
- Goal
- Remove tramp oversize before the filler without reducing the 5 t/h packing rate.
- The solution
- Two ZPS-1000 straight-through screens with 30-mesh SUS316 mesh were flanged between the final screw conveyor and the filler surge hopper. Oversize ejects continuously to a reject tote; the filler never sees tramp material.
- Machine configuration
- 2 × ZPS-1000
- 30 mesh SUS316 cloth
- Inline flange-to-flange mounting
- Continuous oversize reject chute
“The filler has not jammed once since the two machines went in. Our weekly cleaning shutdown became a monthly one.”
