“…Hoppers can be either two-dimensional such as coal transmission on conveyor belts in mining industries, or three-dimensional such as the gravity-driven silos in food industries. Issues with hoppers that can limit or even stop the production rate of a company include, but are not limited to, rat-holing, 10 segregation, 11 dust-spreading, 12 and clogging/bridging. 13–15 Clogging, the main focus of this paper, occurs due to particles forming an arch at the hopper exit, which in turn stops flow through the hopper.…”
