Abstract

In order to study the wear of concrete on the wall surface when it flows in the chute, the numerical simulation software Fluent was used to analyse the erosive wear of concrete on the chute, the concrete is in a laminar flow state in the chute, according to the pressure distribution of concrete on the chute under the influence of the cloud diagram as well as gravity, the bottom area of the chute is the main contact surface with the concrete, which is also the main location where the wear occurs. Using the DPM particle model, simulate the erosion wear of concrete in the chute, the wear occurs in the same location with the aggregate accumulation area, the wear is serious in the bottom of the area near the centre axis, chute slope and inflow velocity can affect the wear of concrete on the chute, and based on the Hut collision theory that the larger the aggregate particle size, the more serious the destruction of the wall, the aggregate particle size will be controlled to within 10-20mm. In order to extend the service life of the chute, it is proposed to optimise the chute shape design to reduce the chute replacement rate.
