The root of these problems lies in the design flaws of the transfer chute. In response to the above problems, designers Stuart-Dick and designer Royal have summarized 6 design principles for bulk material transfer chute, and designer Roberts also put forward the problems that need to be considered in the design, which are summarized as follows.
Feeder overpressures can be awkward to assess due to the many variations of bin geometry and variations in the properties of bulk materials, particularly according to whether the bin is of mass flow design and the feeder extracting from the total interface area, but I would make three more points.

Weba Chute Systems has successfully implemented its innovative approach to bulk materials handling in the diamond-mining industry. By applying scientific principles to transfer chute dynamics, Weba Chute systems eliminate common issues associated with conventional methods, yielding significant cost savings for diamond mines.
This document discusses design principles for chutes used to direct the flow of bulk solids. It outlines two key principles: 1) Chutes must be steep enough to prevent plugging at impact points like changes in direction, but no steeper than needed to minimize wear. 2) Dividing the deflection of material flow into two half angles through impacts can help …

However, chutes should be no steeper than necessary for cleanoff, to keep material velocities and wear to a minimum. 1 Source: Stuart-Dick, D. and Royal, T.A.: Design Principles for Chutes to Handle Bulk Solids. Bulk Solids Handling, Vol. 12, No. 3, Sept. 1992, pp 447-450.
Extending the above to the design of continuous flow (i.e. ones that meet the demand for high flow volumes) transfer chutes follows: •The key to the design of such transfer chute starts with having an accurate material trajectory. This is the key to controlling the flow down the body of the transfer.
We utilize the latest Discrete Element Modeling (DEM) software to simulate flow of material and optimize chute design. For critical applications, difficult transfers, and varying material properties, we go a step further …
This document discusses two key design principles for chutes used to handle bulk solids: 1. Chutes must be steep enough to prevent material from adhering or plugging at impact points, such as where the chute changes direction. The minimum angle can be determined through testing. 2. Chutes must have sufficient cross-sectional area to avoid reducing …

A rock box is normally used when you want material on material contact to prevent chute wear at the impact zone. If segregation or different products are run in the same chute a rock box is not practicle and a better chute design is required to collect and direct the flow properly to the receiving system.
