More photos...See schematics |
The model MIC manufactured by Bernardi Impianti offers different solutions for production capacity (from 80 to 400 t/h), structure (lower, elevated, tower) and installations (on concrete bed or faster on steel beams). This kinds of plants are the more widespread and esier to control. They also offer the best guarantee in terms of product quality. The production process is of the modern plants is fully automatic. MIC plants requires just one working operator as wall as another operator loading the feeders. The control cabin is placed strategically and inside the operator can find all necesary instruments to control and drive plant. In fact he can set the requested process parameters and determinate: production cycle, product quantity and quality, final temperature of the agregate and so on.When production parameters are defined and set, the operator work becomes a merly control function. |
