The examples from Sokolovska uhelna show that a suitable shaping of the revolutions diagram within the stoppage process can help to reduce stress on the belt and other parts of the conveyor. Mathematical modelling can shape a specific revolutions diagram for an individual conveyor. The optimal brake time for a whole complex of conveyors can be defined, allowing different revolutions diagrams to be tailored to an individual conveyor. The phase of design and conveyor behaviour within different conditions can be modelled. Startup and stoppage phases can be simulated for all situations, including startup via frequency controller or resistive starter. Based on selected parameters, the tension force can be stated in such a way that overstrain to the belt and other parts of the conveyor can be minimised. It is also possible to simulate conveyor responses to load changes and other influences. Mathematical modelling of belt convey ors provides very precise results when com pared to practical measurements. It is a developing software that improves with every new setting. As an object-oriented software it can easily be suited to specific client requirements. Controlled braking avoids downtime and conveyor failure. It is necessary for conveyor belt systems to use controlled braking for technical and wear reasons.
