Calibration of cohesive DEM parameters under rapid flow …
The discrete element method (DEM) is conducive to optimizing bulk material conveying equipment. Calibration experiments are essential in DEM simulation, requiring particles to accurately replicate the flow behavior from rapid motion (up to a maximum of 6 m/s) to stable accumulation in bulk material handling.

Dynamic Behaviour of a Conveyor Belt Considering Non-Uniform Bulk
For the conveyor belt, variable material flow influences the energy efficiency of the speed control technology significantly. The fluctuation of material flow on the conveyor belt will lead to the detrimental vibrations on both the belt and the conveyor while the conveyor works at certain speeds. In order to improve the model inaccuracy caused by the uniform …

Modelling of material removal due to sliding wear caused by bulk
In the mining industry, the process of transferring bulk solids such as iron ore leads to surface wear of handling equipment. Studies show that approximately 82% of the energy loss is attributed to the bulk material sliding along the bottom of the chute, while 9% of the loss is due to the material sliding against the side walls [2].

A review of granular flow in screw feeders and conveyors
The screw feeder is a special form of screw conveyor. It is generally used to control the flow rate of bulk material from a bin or hopper, as shown in Fig. 2. The size of the hopper opening into the casing is almost one to three times the screw pitch. In tabular casing, a part of screw is inside, through which granular particles are to be conveyed.
