/ Technical audit

We identify the cause of deviation from the process mode

The technical audit of a drying system covers the process mode, the mechanical condition of the drum and gas path, heat generating equipment and automation.

/ Repair

Partial repair and overhaul

Partial repair

When the drum, drive and heat generating equipment retain their main service life and full reconstruction is not economically required.

  • tyre replacement
  • roller support restoration
  • girth gear repair
  • seal replacement
  • drum shell repair
  • lining and flight restoration
  • heat generator repair
  • gas duct repair
  • drive repair
  • feed and discharge system repair
  • electrical system restoration
  • instrumentation repair

Overhaul

An overhaul involves in-depth fault detection with restoration or replacement of worn main units.

  1. 01

    Disassembly and fault detection

    Determining the actual condition of parts and units.

  2. 02

    Restoration

    Machining, repair or manufacture of parts.

  3. 03

    Replacement

    Installation of new components where restoration is technically or economically unjustified.

  4. 04

    Assembly and adjustment

    Restoring geometry, adjusting mechanisms and drives.

  5. 05

    Testing

    Testing of equipment systems.

  6. 06

    Commissioning

    Installation supervision and commissioning, depending on the scope of work.

/ Upgrade

Improving the efficiency of existing equipment

If the mechanical base of the drum and heat generating equipment still has service life left, an upgrade may be more rational than full replacement of the system.

Drum and internal flights

Changing flight geometry to improve heat transfer within the equipment's design limits.

Heat generating equipment

Renewal of burners and automation systems.

Material feed system

Upgrading feeders and loading devices.

Discharge system

Mechanisation or automation of discharge operations.

Gas path

Renewal of gas ducts and seals.

Automation

New PLC, HMI, sensors and frequency converters.

Important: the potential for higher throughput and lower heat carrier consumption is determined after analysing the process mode, raw material characteristics and technical condition of the equipment — specific figures are given only based on project calculations.

/ Automation

Drying system automation

A control system upgrade automates monitoring of the temperature mode, drum loading and heat generating equipment operation.

Process cycle

  1. Raw material loading
  2. Feed into the drum
  3. Drying
  4. Temperature monitoring
  5. Discharge
  6. Conveying

  • HMI
  • VFD
  • temperature sensors
  • pressure sensors
  • level sensors
  • flow meters

/ What to choose

Repair, upgrade or replacement?

Repair

When the equipment's original performance needs to be restored.

Goal: return the equipment to working order

Upgrade

When existing equipment is working or repairable, but its throughput, automation or operating characteristics need to change.

Goal: improve the existing system

Replacement

When remaining service life, structural condition or restoration cost make further repair economically unjustified.

Goal: replace the equipment with a new solution
