We help connect independent production processes and suppliers with a distributed control system that provides a single interface to control production. And, we help you do more with less energy, from reusing centrifuge braking energy to replacing cane mill steam turbines with variable speed drives and induction motors. The control system scheme for the milling plant section is shown in Figure No. 2 and briefly describes on the following paragraphs. The load current of the cane leveler, cane knives and unigrator indicates of the amount of cane being fed in the mill. The level of the cane chute of the first mill controls the speed of the feed conveyors.

Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between Valmet supplies pulp mill key technology to Suzano in Brazil. The delivery covers the main parts of a green field pulp mill comprising wood handling, cooking plant and fiberline, pulp drying and baling, evaporation, power boiler, recovery boiler, causticizing and lime kiln, including an integrated automation solution for all process areas.
