Twin Screw digital bagging machine
Our twin screw machine is used for powders and non-free flowing materials as one bag is filling another bag can be removed making sack filling continuous and faster, a turnover device diverts the material between the two screws.
The machine is set to target weight using the digital weighing controller; once the machine is started the inverter driven screw fills the first bag to target weight the machine then diverts to the second station filling the second bag.
The machine can be supplied for both valve sacks and open sacks, for open sack filling a special stainless steel adapter can be used with dust extraction points.
The 600DC-SCREW is both compact and mobile simply position the machine under your hopper or Silo and connect a flexible connection from the outlet of your vessel into the inlet on top of the machine.
Two bags per minute depending on the type of material and product density for an accurate filling rate please send us a product sample.
Valve sack filling head
The bag is positioned onto a straight Nozzle with a tapered end each nozzle is designed to suit your valve sack, this provides a tight fit to prevent product dust from entering into the work enviroment.
Stainless steel screw
The screw is manufactured to suit your product the pitch of the screw will be selected to provide the best material flow through the nozzle, sometimes a screw needs to have a staggered pitch for optimum product flow.
Bag support tray
Our support tray has the same profile as the sack when full this prevents the bag from falling to one side during the filling process and prevents mounding of material inside the sack. Uniform sack filling is essential to ensure the operator does not need to pull the sack forward during filling.
The digital weighing controllers feature a large clear display screen with easy to use menus. Clear instructions are displayed on the controller for quick-weight selection. The digital weighing controller has ten preset weights for quick target weigh selection
An inverter drive controls the flow of material weighing with an accuracy of 20g per bag. An automatic in-flight compensation feature covers any variation in material specific gravity this sends a signal to the inverter to ensure the screw stops a just the right moment to achive target weigh without overfill.
Dust extraction points can be fitted around the filling nozzle as an optional extra to prevent excess dust escaping into the working atmosphere.
