The mild steel support frame constructed of heavy-duty tubular steel with wheels is the basis for this design. On top of the support frame a stainless-steel weighing hopper with a blending screw, transport conveyor and liquid adding unit are placed. Due to the two wheels, the frame is movable with the help of a forklift with a hitch.

The bulk material will be discharged through a weighing hopper. The flow from this hopper is operated by a slide and will control the output of the material through the loss in weight system.

From the hopper the material will enter the blending screw, which is designed to blend granular material with liquid or powdery material. At the beginning of the screw a separate inlet is installed that will facilitate the input of liquid product.


The blend screw is equipped with a bypass. This means that the material can bypass the screw when it doesn’t require any blending. The conveyor is placed underneath the blend screw and has two product inlet points, one at the bottom underneath the bypass and one at the end of the blend screw where the blended material will come out. The product is transported upwards by the conveyor to be discharged at 6 meter height (height is adjustable).

Close to the blending screw a pump will be installed that pumps the material from an IBC or tank. The IBC or tank is placed on a weighing scale and through the same loss in weight technique it is possible to measure the exact flow of material entering the screw

The complete system operates on a state-of-the-art software system that is user friendly and intuitive to use. The software system on a standalone unit runs on the HMI in the electrical panel.
