Dispense bags of fiber directly into your mixer or truck

Scale-Tron manufactures aftermarket High Pressure Washout system for mixers, Temperature Sensors for use in concrete production and Bagged Fiber Dispensers.  The company also imports Concrete Mixers and Bulk Fiber Dispensers from Italy.
High Pressure Mixer Washout blasts the partially cured concrete from your mixer in minutes.  Hand cleanup gun is useful for cleaning hard to reach corners and chutes, buckets etc.
Bowl feeder dispenses fiber onto your aggregate belt by loss-in-weight scale
Dispenser for bags of fiber.  Load it and forget it. Bags are dispensed, one per yard of concrete or whatever you choose, from the formula, exactly like admixtures.
The Dosmec Fiber Conveyor sends your fiber or fiber bags aloft to your mixer or truck. And it’s portable too!

Imagine adding the right amount of fiber to your batch – every time, recorded in your batch reports.

Fiber bag dispenser adds bags of fiber to your concrete before mixing


Load it and forget it.  For automatic production, the fiber bag dispenser, or fiber bag doser, drops your fiber or other additives reliably into the mix.  No need to manually dispense it because the bag dispenser holds up to 28 bags.  Drop one, two or more, depending on the concrete batch size.  Treat your fiber like an admix, proportioning it to the batch size . . .

  • You can position it to drop bags into the aggregate scale, onto the aggregate belt or directly into a concrete mixer or truck.
  • Load the fiber bags into the bag dispenser at the start of operation.  You place bags one at a time into the feeder buckets.  Easy to do.
  • Chain and bucket dispenser drops one bag at a time, guaranteed.
  • It reliably holds and dispenses all sizes of bag up to 12″ wide, with no height limitation.  It can also hold two smaller bags or containers of granulated additives.
  • A half-second start pulse is required; the rest is automatic.
  • You can run it from the admix outputs of most batch controllers.  No special software necessary.
  • Low power 110 or 220 volt single phase motor.  No starter required.
  • We have special models for other quantities and oversize bags.
  • Uses standard North American parts to ensure you can replace them if necessary.


Because the fiber bag doser runs from the admix output of a batch controller such as BatchTron, you can proportion bags of fiber just like any admix. Set a quantity of one bag per yard (or cubic meter) and the fiber bag system will drop one bag, two or more depending on the batch size.  Your controller will report the number of bags on the batch report.  On formulas not requiring fiber, set the quantity to zero in the formula. No more mistakes.


Installation is easy.  You should select a position where the bags can be fed onto the aggregate belt or the aggregate scale.  Alternatively, into the aggregate holding hopper or directly into the mixer or truck.  You should choose a position that is convenient for loading the bags into the bag dispenser.  It should be covered to prevent rain or snow from entering.  Mount the bag dispenser on its four bolting points and run a three-conductor cable to the control panel.  Consult the control panel manual for connection details.  We are available at all times for help.

Optional extras

  • Manual controller –  for plants without automatic dispensing capability, dispenses preset quantity of bags.  Push button or separate start pulse initiates operation.  Electronic counter – set any quantity of bags per batch.  Alarm output and lamp warn when last bag is reached.
  • Last bag detector – photo-electric sensor, now standard on all dispensers.
