Linear weigher unit

The linear weighers are incorporated as a dosing system in COALZA's vertical packaging machines to obtain the net weight of all kinds of products from 20 to 5,000 grs and with a volume of up to 25 litres.

How it works:

The weigher is composed of :

1. Gross chute for dosing up to 95% of the weighed product, allowing a fast process.

2. A refining channel to improve accuracy, by dosing the last 5% of the weight.

This hopper will be the device that will give us the information to coordinate the “start/stop” of the rest of the components.

The volume of product in the hopper and in the channels will be controlled by photocells.

Apart from the PC5000, the “belt model”, these channels are designed with individual high amplitude vibrators, specifically designed to feed high adhesion products.
