overview

Key Learning Objectives

  • Discover the four-step tried and tested approach to chute design
  • Appreciate the importance of calculating the material trajectory accurately
  • Learn how to use your site observations to correct design faults
  • Manage cohesive and adhesive ores that create chute blockages or require regular cleaning
  • Learn methodologies for minimising dust generation
  • Determine how wear can be minimised in a transfer chute through material flow control
  • Gain a working knowledge of design evaluation, when it should be used and what is the best method

About the Course

The course will look at the design of numerous types of transfer chutes, how to select the correct type, and the limitations of each design.

It will then look at the basic considerations that need to be taken into account when calculating the material trajectory, the various methodologies developed and then work through trajectory calculations using software developed by the instructor and Dr Sham Huque.

Practical aspects of transfer chute design, and things we can learn from site observations will be discussed, along with the theoretical design of all types of transfers in a step by step logical way. It will look at ways designers can take advantage in the design process from the design experience of the instructor.

Some other areas covered include:

  • Practical ways how to manage wet and cohesive materials that have the propensity to create chute blockages or require regular cleaning
  • How dust can be absolutely minimised in a transfer chute without using a bag house
  • Design evaluations methods such as DEM and dynamic scale modelling and show participants the limitations of both methods.It will make recommendations as to what is the best approach
  • Wear and how it can be best managed and minimised in a transfer chute
  • Various wear mediums that are used and how to select the best solution

Finally the course will look issues raised by participants and then move onto a practical exercise in designing a transfer.

 Case examples and analysis

There will be detailed examination throughout the course of various chute designs – good ones, bad ones, and mediocre. This session will be a further opportunity to learn through benchmarking against a myriad of industry examples.

  • Observations over the years of what worked, what didn’t
  • What was done to fix those problems that didn’t work
  • What have we learnt from the good and the bad?

Interactive design exercise

Designing a transfer chute

This session will be a practical application of the theory and case examples discussed throughout the preceding couple of days. This is envisaged to take a number of hours, with the participants using their laptops, supported by trajectory software provided by the instructor.

The purpose of the session is to actually design a basic transfer chute from scratch, guided by key parameters and through the instructor’s assistance. Constructability and maintainability are fundamental principles reflected on throughout this session.

Parameters considered will include

  • Key aspects of material properties like cohesive properties, particle size and size distribution, flow properties, strength
  • Bulk handling systems and their effects on chute designs: shape, ease of fabrication, clearance dimensions etc
  • Chute sizing considerations based on these processes
  • Understanding potential issues with surge, dust, blockages, wear etc

This design exercise is to help provide participants with a foundation of basic engineering principles through practical application, to then take this example and understanding back to their workplace to use, test, and benchmark it against existing designs and operations at their workplace.
