Key Learning Objectives
- Review common chute problems (eg. plugging, buildup, wear, spillage, dusting)
- Understand basic components of a transfer chute system
- Discuss bulk solids flow properties and their use in chute design/troubleshooting
- Review calculations for estimating stream trajectory and chute capacity
- Learn about Discrete Element Modeling (DEM) technology for chute evaluation
- Examine chute designs for handling cohesive, wet, sticky, abrasive, and dusty materials
About the Course
This course provides participants with an overview of transfer chute problems and their costly implications, along with an introduction to general design principles required to have effective chute operation.
Basic chute components are reviewed so that a complete understanding of the transfer chute system is achieved. Bulk material flow properties required for chute design are presented, as well as discussion of key chute design inputs.
Review of material stream trajectory calculations is covered, as well as estimation of chute capacity assuming throughput requirements and stream velocity. Example chute designs are reviewed, especially in cases where DEM technology has been effectively utilised to solve or prevent chute problems.
The course participant will learn about effective chute design through presentation of multiple real-world case studies involving common mining and minerals applications. Focus will be upon chutes handling iron ore, coal, bauxite, and coarse ores.
Note that this course is not a replacement for our 3-day intensive “Transfer Chute Design Engineering” course. Rather, it is an excellent complement to the “Bulk Materials Handling Problem Solving” masterclass.
This 1-day chute course will effectively arm the participant with a solid working knowledge of chute problems, troubleshooting, and a path forward to implement proven solutions required for reliable transfer chute operation.
