Chute Design Essentials How to Design and Bulk

4.2 Chute Body. The chute body should be designed to suit the transfer requirements, without changing the direction of the material severely. The area of the chute containing the body of the material flow must be at least 2.5 to 3.0 times the area of the material, based on the design capacity of the conveyor and the material speed at the point of consideration.

Designing reliable transfer chutes with bulk material

For chutes we will check the material velocities and build-up angles with first principle calculations. When the final design 3D model is adequate, we will run a DEM simulation of the chute which we then use to optimize the final chute design. Here is a real-case example of a project we worked on for a client.

2007-2-12  bulk material from one conveyor belt to another, often via a three dimensional path. The importance of correct chute design to ensure efficient transfer of bulk solids without spillage and blockages and with minimum chute and belt wear cannot be too strongly emphasised. The importance is accentuated with the trend towards higher conveying speeds.

Transfer chute analysis with Bulk Handling Review

DEM has become a viable chute design tool over the last 15 to 20 years with the introduction of increasingly powerful computers. At its most simple, DEM models a bulk material as a series of spheres which are given appropriate properties such as density, inter-particle and particle-to-wall frictions and adhesion among others.
