1. Project Title
  • Discharge Conveyor Replacement ($290,000)
  1. Project Summary
  • The project involved the replacement of Discharge Conveyor 2, originally installed in 1975.
  • The conveyor was exhibiting advanced internal and external component deterioration and was considered uneconomical to continue repairing.
  • Its existing length and arrangement were also no longer suitable for the current process configuration.
  • DMD developed the coordinated design required to replace the conveyor while reconnecting the numerous existing product chutes, aspiration ducts and supporting infrastructure.
  1. Sector
  • Animal Feed Manufacturing
  • Materials Handling
  1. Project Location
  • North West England
  1. Client Challenge
  • The replacement conveyor had to be integrated into an existing operational plant with limited space and numerous fixed interfaces.
  • A total of 13 tie-in points were required across the existing product chutes and aspiration ductwork.
  • The original conveyor had not been installed square to the surrounding building structure, creating significant alignment, orientation and dimensional challenges.
  • The replacement arrangement needed to accommodate the existing process connections while improving access, maintainability and suitability for the current operating requirements.
  • Installation planning also had to minimise modification work and disruption to the surrounding plant.

  1. Engineering Disciplines
  • Mechanical Handling
  • Piping and Ductwork
  • Structural
  1. Project Delivery Approach
  • A detailed laser scan and manual verification survey were completed to accurately establish the position, orientation and condition of the existing installation.
  • Particular attention was given to confirming the 13 existing tie-in points and the non-orthogonal alignment of the conveyor relative to the building.
  • Detailed chute and aspiration-duct development studies were undertaken to connect the replacement conveyor into the existing process arrangement.
  • Conveyor, structural and ductwork designs were coordinated within a single 3D environment.
  • Potential clashes, access restrictions and fabrication issues were identified and resolved before construction.
  • Installation, lifting, maintenance and future component-replacement requirements were considered throughout the design.
  • The final arrangement was developed to minimise site modification and simplify installation within the available shutdown period.
