The new dosing and mixing system Somos BB 500 batch-dosing device of Protec Polymer Processing is ideal for feeding injection molding machines as well as extruders with multiple component mixtures. The new gravimetric batch dosing system is suitable for four components and has a throughput rate up to 500 kg/h.

The batch dosing device is designed for up to four free-flowing components and throughputs up to about 500 kg/h (at a bulk weight of 0.6 kg/l). The device is mounted directly on the material intake of the processing machine – or on a frame next to the machine – and can be equipped with Somos suction conveyors for automatic filling of the material supply tanks. Touchscreen control provides comfortable operation with a graphic user interface, specifically tailored to the range of tasks of a batch dosing device.

Up to 50 stored, individual mixture formulas can be called and immediately applied. The individual components are successively dosed in a weighing tank in accordance with the formula and the total batch is subsequently homogeneously mixed in a mixing tank placed underneath. Depending on the proportion of a component, the batchdosing device achieves a precision of ± 1 % up to ± 0.5 % of the dosage weight of the corresponding components.
