The conveying and mixing packaging production line consists of multiple interconnected devices. A belt conveyor first transports the material to a drum mixer, where the material is thoroughly mixed and homogenised through stirring. The mixed material then falls through the discharge port onto another belt conveyor, which lifts and transports it to the packaging machine, where it undergoes metering, filling, sealing and other packaging processes. This production line enables automated continuous operations from material conveying, mixing to packaging, and is suitable for various granular and powdered material mixing and packaging applications.
