Don't Fall Short With Transfer Chutes
The bottoms of chutes are frustums of cones or truncated pyramids to aid the discharge of materials. Good chute design requires more than having the correct cross-sectional area and slope. When bulk material discharges to a chute and impacts the chute surface, its velocity decreases. The larger the impact angle, the bigger the change …

Stuart-Dick&Royal-Design Principles For Chutes To Handle Bulk …
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 …

RATIONAL DESIGN OF CONVEYOR CHUTES
To increase the material speed down the chute, the chute must be close to vertical - at 900 to a horizontal belt. But angles above 60° result in a rapid decrease in forward speed. Conversely, decreasing the chute angle has the effect of increasing the material speed component in the direction of belt travel.

Simulation of Transfer Chutes
Transfer chute stations can be contentious points in any bulk material handling plant. In addition to proper redirection of the bulk material stream, wear and dust problems often are related to the design of the involved chutes. With high mass flow rate, the optimisation of transfer stations is especially important for belt conveyors.
