How to Inspect A Concrete Plant

We hear all the time “inspect your plant”, but what does that really mean?

First, I think we have to acknowledge that there are a couple of types of inspections.

  • Basic or Simple Inspection
  • Semi-Full Inspection
  • Full Inspection or Complete Inspection

Depending on how much concrete you are producing each hour and day will determine how often you should conduct each inspection. If you only produce a few hundred yards per day you may be able to have a basic inspection each day.  If you are producing a hundred yards or more per hour all day, you should probably be doing a basic inspection a couple of times each day.  At a minimum we would recommend a basic inspection each day, a semi-full inspection weekly and a full inspection quarterly.

Basic Inspection

  • Visually inspect the plant from normal access areas.
    • Pay special attention to conveyor belt tracking and belt condition
    • Bearing making noise, wiggling, or having lots of grease or even smoke.
      • Look specifically at head and tail pulleys on conveyors and head and tail of augers
    • Gates opening and closing without obstruction
    • Air compressor
  • Pay close attention to
    • New or unusual sounds
    • Gates or other moving parts not moving smoothly – jerking
    • Anything that appears out of its normal place or not operating as normal

Semi Full Inspection

When completing a Semi-Full Inspection it is also a good idea to preform maintenance tasks.  This inspection requires all the steps of the basic inspection but also requires you to access the hard to get to places that you can’t see for a basic inspection

  • Visually inspect each part (paying special attention to moving parts) on each of the following systems.
    • Aggregate bins, aggregate batchers, transfer conveyors, gates
    • Cement Silo Gates, Cement Batcher, Augers, discharge boots
    • Water Meter, Hoses, Scale (if applicable), discharge boots
    • Air Compressor, air fittings, hoses, actuators, solenoids
    • All other systems you may be operating (generator, hydraulics, etc.)
  • Identify any unusual sounds, motions movements, etc.

Full Inspection

The full inspection includes all steps of the both the basic and Semi-Full inspections, but the full inspection also includes the most difficult places to access.

  • Open and Visually Inspect Cement Silo and Batcher Dust Collectors
    • Look for signs of water leakage, build up, blockage or signs of broker bags or plugged cartridges.
      • When the inside of the dust collector is extremely dusty, it is usually a good sign the bags or cartridge need to be replaced. If the collector is self-cleaning, it could also be an indicator the collector is not properly functioning.
    • Empty Bins and Batchers and inspect high impact areas
      • Look for signs of work steel, corrosion or rust
        • Welding in a steel liner plate or urethane sheet is much easier when wear is addressed early and before all weld-able metal has deteriorated.
