Bulk material conveying equipment including screw, chain and belt conveyors at an industrial plant

Which conveyor suits which material, distance, inclination and temperature, and how to match discharge valves with dust collector hoppers.

What this article covers

  • Selection method for bulk conveying equipment under real plant conditions
  • The parameters that decide sizing: gas volume, temperature, dust or pollutant load and the outlet limit
  • Material and media choices that affect service life and running cost
  • Installation, commissioning and maintenance points that are often missed in quotation stage
