Q1: In short, what is Bruno about?
Bruno is an intuitive software program for simulating the aggregate production process and it includes all the required Metso Outotec equipment: feeders, crushers and screens. The user enters basic feed material and machinery data into the process and the software predicts how the process will perform. This way, the customer can determine the most optimal process for each specific need.
Q2: What is the main benefit of using Bruno?
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.
Q3: Could you describe a scenario that showcases the value of Bruno?
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.
On the other hand, it might be that production targets change and the current setup doesn’t fit the needs anymore. With Bruno, the customer can quickly and easily find out how to reset the process flow. In addition to resetting the process flow, Bruno offers the possibility to try new equipment. For example, in certain applications it might be effective to change the HP crusher to a GP crusher. One real life case was when Bruno helped Riverbend to choose the equipment best suited to their needs.
One of the most common reasons why a plant doesn’t deliver as expected is the fact that rock type is not properly taken into consideration. We analyze a rock sample from the customer site to determine its specific characteristics and feed this information into Bruno. For instance, high abrasiveness can cause unexpectedly short wear part lifetime, which increases downtime and operating costs.
