Zimbabwe Automatic Bulk Bag Degassing Packing Machine

The horizontal screw degassing packaging machine features a triple-degassing system comprising large- and small-diameter horizontal screw feeding, mechanical extrusion degassing, and vacuum-assisted degassing. After coarse feeding by the large screw, the material is mechanically compressed by an extrusion plate to expel most of the entrapped air; during fine feeding by the small screw, a vacuum system further removes residual air. Finally, strong bottom vibration combined with cylinder-driven bag-shaking compaction ensures superior degassing performance compared with vertical-screw models, making it ideal for ultra-high-air-content, highly fluffy powder materials. The equipment emphasizes gravimetric weighing and metering, and comes standard with air-bag bag clamping, automatic hook release, dual dust collectors, and a triple-degassing system. The lithium-battery-specific version is tailored for core lithium-battery materials such as lithium iron phosphate and graphite powder, producing densely packed ton bags that can be directly stacked and palletized, seamlessly integrating with automated packaging lines.

Product Description

The degassing packaging machine is a specialized equipment designed for high-air-content, fluffy powders. It is available in two configurations: vertical-screw degassing and horizontal-screw degassing. By integrating screw feeding with mechanical or vacuum-based degassing, this machine effectively removes entrapped air from the material, increases bulk density, and prevents ton bags from bulging or collapsing during transport. It is a core solution for packaging high-air-content powders in the lithium-battery and chemical industries.

The horizontal screw degassing packaging machine features a triple-degassing system comprising large- and small-diameter horizontal screw feeding, mechanical extrusion degassing, and vacuum-assisted degassing. After coarse feeding by the large screw, the material is mechanically compressed by an extrusion plate to expel most of the entrapped air; during fine feeding by the small screw, a vacuum system removes any remaining air. Finally, strong bottom vibration combined with cylinder-driven bag-shaking compaction ensures superior degassing performance compared with vertical-screw models, making it ideal for ultra-high-air-content, highly fluffy powder materials. The equipment emphasizes gravimetric weighing and metering, and comes standard with air-bag bag clamping, automatic hook release, dual dust collectors, and a triple-degassing system. The lithium-battery-specific version is tailored for core lithium-battery materials such as lithium iron phosphate and graphite powder, producing densely packed ton bags that can be directly stacked and palletized, fully compatible with automated packaging lines.
