Silo Weighing

The most complex part of the entire implementation is the base upon which the cement silo is placed. These bases must be designed in such a way, to provide the maximum security against earthquakes and strong winds, without reducing the weighing accuracy.

Protem's cement silo weighing bases has been designed especially for the territory of Greece that is influenced very often by strong earthquakes.

For the installation the silo must be lifted with a crane, and after that the weighing bases must be placed in the exact same spots where its legs were located. Next, the silo must be carefully be placed and secured on the top flange of the bases. Finally the embedded lift-up protection rods must be correctly adjusted.

The height of each weighing base is 240mm.

For accuracy reasons, the screw conveyors connecting the silo to the cement scale as well as the silo’s feeding tubes must not be fastened in steady points other than those of the silo’s itself.

For silo of up to 50 & 75T load cells of 25T are used, while for the 100 & 125T silo 4 load cells of 40T each are used.

The weighing error is less than ± 0,2 % which practically equals less than ± 200 Kg in an 100T silo.
