- Description
- While calculation procedures for the design of storage bins for dry bulk materials have been long acknowledged, the design of wet solids storage vessels is an on-going issue. Because the effects of the wet solids properties such as consolidation behavior, water permeability and viscosity on the material discharge have not been investigated yet, existing design procedures employ the principles of Jenike for dry bulk materials to describe the stress fields in a surge bin during initial filling and discharge. This paper focuses on both theoretical and experimental investigations of the discharge mechanisms and loads acting on the wall of a tank filled with a mixture of solids and water. The objective is to confirm whether the Jenike principles can be applied for the design of wet solids concentrator vessels. Tekscan® tactile pressure pads were applied to measure the profile of normal stress acting on the hopper wall of a wet solids bin, especially during discharge. Results are compared with the stresses calculated by applying standard calculation methods for dry bulk materials hopper design in conjunction with the effect of hydrostatic pressure. The results indicate that wet solids are behaving like dry bulk materials. However, the Jenike design method may be too conservative, leading to hopper half angles steeper and tanks higher than necessary.
