Gravimetric Filling Machine (with Vertical Auger Filler)
Servo-driven powder packaging machine for filling free-flowing powders and granules into 5kg to 60kg bags
Ideal for filling free-flowing powders and granules into 5kg to 60kg bags, this filling machine with vertical auger filler uses a precision servo drive motor to drive the screw shaft, providing faster response, smoother acceleration and deceleration, and higher motion accuracy compared to conventional auger fillers. The result is improved filling precision and faster packaging performance. The system consists of the main filling valve, servo-driven auger filling unit, pipeline metal detector, pneumatic bag clamping device, weighing module and control system, and an integrated dust collection system. Mounted on a compact frame with mobile casters, it features a modular design for convenient cleaning and maintenance.
For easy dry and wet cleaning between production batches, the screw housing adopts a quick-release clamping design, while the feeding section is mounted on a linear slide rail for effortless removal and cleaning. The metal detector is also installed on a sliding track for quick disassembly and maintenance. To accommodate different bag sizes and heights, the filling head features an adjustable height design, ranging from 400mm to 600mm above the roller platform. The gravimetric filling machine supports laminar flow installation, offering a compact footprint ideal for cleanroom environments.
