700DC-VS1 Single screw feed

Single screw digital sack filling and weighing machine with integrated hopper.

Our new single screw sack filling and weighing machine features an Integral hopper for the collection of materials from Bulk bags and IBC containers.

This machine is designed for the filling and weighing of difficult powders into valve sack bags. When materials are not free flowing a screw must be used to pack the material into the valve sacks.

The single screw agitates the material as it feeds breaking the material up, for more difficult materials a paddle shaft can also be fitted within the hopper to brake material up before it reaches the screw.

Machine Filling sequence.

Target weight is selected from the weight controller once selected the controller will display start and the filling sequence can be started.

Valve bag is pneumatically clamped on the filling nozzle and supported on weight platform, The start button is pressed to start the filling sequence, Machine fills fast for 23Kg, screw speed slows for final 2Kg. Once target weight is reached the screw reverses to prevent material spillage. The 25Kg valve sack can now be unclamped and removed.

The machine pictured is packing material directly from a 500Kg bulk bag. The bulk bag is hung above the machine, the bag outlet spout is opened inside the machine hopper. The machine controls the flow of material until the bulk bag is empty and the material is packed into twenty 25Kg valve bags.

We can supply this machine with a larger hopper with heights to suit your requirements. Dust extraction points can also be fitted and location brackets for hopper loaders.

Please do not hesitate in contacting us if you require any information regarding bulk handling into valve bags, open sacks or tubs and boxes we have a wide range of filling machines for all sorts of applications.
