Modeling Method of Cement Clinker Accumulation Body Based onDynamic Neural Network

Abstract

Abstract: The particle packing is an important issue in engineering.In order to construct the discrete element numerical model of the particle accumulation body,an experiment for collecting its structural parameters such as diameter and coordinate was designed firstly.With the cement clinker packing of the grate cooler in the background,cement clinker was used to form the accumulation body.And a series of images were collected by cutting the particle accumulation body into slices.Then a battery of treatments was carried out to obtain its structural parameters.At the same time,a prediction model was trained based on neural network in order to rebuild accumulation body model and its statistical accuracy was verified.The good precision of the model indicates that it meets the modeling requirements to a certain extent.
