In the field of packaging fertilizers, chemical raw materials and highly corrosive products, traditional painted steel bag material feeding equipment (such as CP4900, CM4900-3) faces serious challenges: acidic vapors, salt dust and chemical solvents accelerate the corrosion of the equipment, resulting in shorter mechanical life, frequent downtime for maintenance, and even contamination of the product.
To address this pain point, the new CP4900-SS Stainless steel bag feed-in device unit offers a zero-compromise solution for specialized industries with an all-stainless steel body and modular motor system.


Ⅰ. Subversive Design: Made for Corrosive Environment
Core Selling Points:
- All Stainless Steel Frame
- Adopting food-grade stainless steel molded frame, resistant to chloride, sulfide, acid and alkali corrosion.
- Application Scenario: Ammonium Salt Packaging in Fertilizer Plant, Chemical Granule Dispensing, Pesticide Liquid Filling Line
- The machine frame is complete with stainless steel, which is specially used in chemical, fertilizer, etc industry.
- Intelligent Belt Type Infeed System (Belt Type Infeed)
- 4PL1200 high-strength PVC conveyor belt: anti-static, resistant to mineral oil erosion, suitable for PP woven bag/paper bag.
- Precise guiding + folding + cutting three-in-one function, to achieve ± 0.5mm seam accuracy
- Compatibility: Seamlessly connects with DS-9/GK-35 series of sewing machine heads, supporting powder/granule/liquid packaging.


Ⅱ. Power system customization: three major motor engines to meet global needs
Stainless steel bag feed-in device CP4900-SS still provides 3 different kinds of inductors depends on your requests: Mitsubish 3-phase induction motor with the gear reduction device, Chinese 3-phase induction motor with the gear reduction device and infinite speed adjusted motor.
