Abstract

Understanding the behavior of granular material in a bunker not only helps to design properly and achieve the correct granular flow, but also needs the engineer to ensure that the bunker is properly designed and conducted to withstand the tasks and demands exercised during its operation. Small and shallow bunkers are commonly used in industry when free space is limited. Shallow bunkers induce the flow of the funnel, which can cause problems such as segregation and agglomeration of the material inside it, which leads to considerable damage to the final product. The design and location of a suitable power supply and an appropriate outlet is still critical and is perceived rather as a science. The paper presents some innovative solutions related to the design, modeling and construction of solid material storage and unloading bunkers.

Highlights

Bunkers are used in the food and construction industry for the protection and storage of powdered materials or cereal seeds
Technologies that use rotating cylindrical sieves involve the need to create a continuous flow of material for processing, the design of the bunker significantly influences the efficiency of the separation process [2]
The seed grains are fed by the feeding vat and the flow of the material is conducted through the outlet positioned at the bottom [23]

Summary

Introduction

Bunkers are used in the food and construction industry for the protection and storage of powdered materials or cereal seeds. Bunkers must be designed in such a way that they are easy to load so that they can be handled by operators. Bunkers be adequately designed so that granular or semifinal material is easy to unload [1]. The utility of adjustable bunkers is important in the technologies that involve conditioning of wheat seeds or for various equipment used for separating impurities. Technologies that use rotating cylindrical sieves involve the need to create a continuous flow of material for processing, the design of the bunker significantly influences the efficiency of the separation process [2]. The way the bunker is designed affects the flow rate of the powdery material, as granular particles can agglomerate inside it. The way the bunker is designed affects the amount of stored material that can be discharged or the stationary space that reduces the actual storage capacity of the bunker [1]
