Bruno simulation software is developed for optimizing aggregate production processes. Bruno is an intuitive software program for simulating the aggregate production process and it includes all the required Metso equipment: feeders, crushers and screens. An aggregate crushing and screening process needs adjustment and changes for various reasons, such as too high production costs or poor product quality. With Bruno, the user can test suggested changes to find out if they have the desired effect without unintentionally compromising the performance some other way. It is much cheaper to spend a few extra hours at your desk making a feasible plan, instead of starting to make potentially costly changes blindfolded. Imagine that you have selected, bought and set equipment for your plant and you are ready to get going. Once the process has started, you notice that the crusher feed turns out to include larger rocks than expected, too large for the crusher to process. The difference isn’t huge necessarily, but it is significant. In that case, you need to reline the crusher chamber, which causes a delay in start-up. If Bruno had been used, we could have estimated the feed size with high accuracy and prevented the issue from emerging in the first place.
