Airslide systems are widely used in industries for the efficient conveying of dry materials. While these systems offer numerous benefits, they can encounter certain challenges that affect their performance and reliability.

By understanding and troubleshooting these issues, operators can ensure the smooth and uninterrupted operation of their airslide systems.

Introduction to Airslide Systems

Airslide systems, also known as fluidized gravity conveying systems, utilize an air-permeable conveyor belt to transport dry, granular, or powdered materials. The flow of air through the belt creates an air cushion that fluidizes and conveys the material. It is important to be aware of the common problems that may arise during airslide operation and their respective solutions.

Top 3 Common Problems in Airslide Systems

Material Blockages

  • Cause: Material blockages can occur due to excessive moisture, particle agglomeration, or improper flow conditions. Blockages can disrupt material flow, leading to system inefficiency or even complete stoppage.
  • Solution: Implement preventive measures such as maintaining appropriate material moisture levels, ensuring material compatibility with the system components, and monitoring flow conditions. In case of blockages, identify the cause, remove the blockage using appropriate tools, and take steps to prevent future occurrences.

Belt Slippage

  • Cause: Belt slippage can result from insufficient tension, improper belt alignment, or excessive material accumulation on the belt surface. Slippage affects the system’s conveying capacity and can cause material spillage or erratic operation.
  • Solution: Adjust the belt tension to the manufacturer’s recommended specifications. Ensure proper alignment of the belt and check for any obstructions or material buildup that may hinder its movement. Regularly clean the belt surface to prevent material accumulation.

Uneven Material Distribution

  • Cause: Uneven material distribution across the width of the conveyor belt can occur due to uneven feeding, inadequate air distribution, or blockages in the air distribution system. This can lead to uneven flow rates and compromised system efficiency.
  • Solution: Ensure uniform material feeding across the belt width, using proper distribution mechanisms such as adjustable gates or baffles. Regularly inspect and clean the air distribution system to ensure even airflow across the entire width of the belt.

Air Leakage

  • Cause: Air leakage can occur at various points in the airslide system, such as improperly sealed connections, damaged or worn seals, or gaps in the conveyor belt. Air leakage reduces system efficiency and can disrupt material flow.
  • Solution: Regularly inspect the system for any signs of air leakage. Repair or replace damaged seals, tighten connections, and address any gaps or damage in the conveyor belt. Ensure proper sealing throughout the system to maintain efficient airslide operation.

Material Degradation or Attrition

  • Cause: Material degradation or attrition can result from excessive friction or impact within the system, improper handling of abrasive materials, or inadequate system design. This can lead to the generation of fines, reduced material quality, and increased system maintenance.
  • Solution: Optimize the system design to minimize friction and impact points. Use appropriate materials and coatings to mitigate abrasion and wear. Regularly monitor material quality and adjust handling techniques as necessary to prevent excessive degradation.

Troubleshooting and Maintenance Strategies

  1. Regular System Inspection: Conduct routine inspections to identify potential issues, such as blockages, belt wear, or air distribution problems. Address these issues promptly to prevent further complications.
  2. Proper Lubrication: Regularly lubricate moving components, such as bearings and pulleys, to minimize friction and ensure smooth operation. Follow manufacturer recommendations for lubricants and intervals.
  3. Employee Training: Train operators and maintenance personnel on system operation, troubleshooting techniques, and safety protocols. Knowledgeable and skilled personnel can proactively identify and address problems.


Common problems can arise during the operation of airslide systems, affecting their efficiency and reliability. By understanding these issues and implementing appropriate solutions, operators can maintain the optimal performance of their air slide systems.

Regular inspection, preventive maintenance, and proper training are crucial for identifying and addressing problems promptly. Troubleshooting strategies enhance system efficiency, reduce downtime, and ensure the smooth conveyance of materials in various industries.
