    Abstract

    A fundamental component of conveying systems for bulk handling is represented by chutes. The main purpose of a chute is the direction change and positioning of bulk cargo, for instance from one belt conveyor to the other. The installation space of chutes is mostly limited, hence their dimensioning is found to be difficult. This can cause congestions, increased abrasion and the edgewise overflow of the material. As a consequent, this effects the proper operation of the conveying system. This thesis deals with the examination of the functional capability of chutes, using the Discrete-Element-Simulation (DE-Simulation). This simulation gives results on the suitability of chutes for conveying bulk cargo. To prove the accuracy of the gained results, the simulation has to be verified by a chute test on a model experimental rig. For that reason, a scale model of the chute is produced and tested on the experimental rig. During the test the bulk cargo coal with scaled graining, also used in the real conveying, is applied. The results can be transferred to reality by the help of model laws and finally be compared those of the DE-Simulation. In the design layout of chutes, special attention should be paid to the inlet of the chute. Wrong dimensioning could lead to abrasion of the wear plate of the chute and the edgewise overflow of the material. The design of the inlet should guarantee the deflection of the bulk cargo adapted to its discharge trajectories. Furthermore the experimental rig shall facilitate the representation of discharge trajectories of bulk cargo.
