The velocity of material vertically entering the chute was estimated at 15 to 34 m/s depending on the fill height of the silo. A three-stage approach was taken. First the existing situation with the highest velocity was modelled with DEM (Discrete Element Simulations), and the results of the wear profile on the existing chute were compared with practice. Secondly, three configurations were designed and the performance of these configurations in terms of wear volume were tested by simulation. Thirdly, and lastly, the performance of the configuration in terms of ensuring material flow through the chutes for a cohesive coal was evaluated. Based on the results of the simulation, two chute designs showed an improved performance where less wear was observed while securing flow through the chute.

Neponset (IL), United States – Since most Conveyor Injuries occur during Routine Maintenance or Cleaning, the Control of fugitive Materials is one of the most important Factors to reduce Hazards and prevent Injuries. In this article Martin Engineering explains how, in a properly-engineered transfer point, each component is employed to maximize its specific function and contain dust and fines, while at the same time offering workers easy access for maintenance.

Neponset (IL), United States – Martin Engineering has helped mitigate dust emissions at the underground limestone mine of a cement production plant by implementing an innovative transfer point solution. Using a specially-designed dust control unit (DCU) to spray a surfactant onto both sides of the cargo stream during transfer onto the main conveyor, Martin Engineering was able to help Continental Cement Company, LLC, suppress fugitive dust both along the underground belt path and during discharge at the outdoor storage yard.
Braeside (VIC), Australia – Timely and efficient material transport from one conveyor belt to the other — with minimum spillage and maintaining the structural integrity of the conveyor belt — is crucial for the long-term viability of any bulk handling operation. By accurately identifying, evaluating and optimizing existing belt loading, transshipment facilities can reduce many unpleasant problems on site and address the safety issues of dust emissions.
