How to Clean a Metal Slat (Chain Plate) Conveyor: Methods, Frequency and Precautions
Quick answer: Yes, metal slat conveyors need regular cleaning. Dirt and oil left on the surface corrode the slats, spoil the appearance and shorten service life. The conveyor body can be hosed down or scrubbed with a sponge and soapy water — smoother slats stay clean more easily — but motors and control parts must never be washed with water. Also keep the line out of prolonged rain and away from acids, alkalis and oil.
Why slat conveyors need regular cleaning
- Corrosion: on lines handling waste water, oil or wet products, dirt builds up on the slats; left uncleaned it corrodes them and shortens their life.
- Running performance: built-up dirt adds resistance and affects conveying speed.
- Product image: in food and beverage plants, a clean line directly affects how customers see the product.
Cleaning methods
| Method | How | Best for |
|---|---|---|
| Wash-down | Hose the conveyor surface to remove dust and deposits | Stainless slats, food and beverage lines cleaned often |
| Scrubbing | Wipe each slat with a sponge and soapy water | Stubborn dirt, periodic deep cleaning |
| Dry cleaning | Sweep or blow off dust and debris | Dusty products, areas that must stay dry |
Comparative tests show that slats washed by rain or scrubbed by hand stay in much better condition than slats kept under cover and never cleaned, and that smooth slats stay clean more easily than rough ones.
Precautions
- Switch off power before cleaning; never wash the drive or control sections, which can damage components or cause electric shock;
- Do not leave the line exposed to prolonged rain or standing water;
- Keep it away from acids, alkalis and oil, and use a neutral detergent;
- After cleaning, check slat gaps and chain tension and re-lubricate if needed.
Why do the gaps between slats change?
Gaps on stainless slat chains either shrink or grow. Friction during operation generates heat, and when temperatures run high the slats expand and the gaps close up, which can cause jamming; long-term wear makes the gaps larger. If gaps look abnormal, check lubrication, load and guide-rail wear.
FAQ
How often should a slat conveyor be cleaned?
It depends on the industry: food and beverage lines are usually cleaned every shift or every day; general industrial lines weekly, with a monthly deep clean. Shorten the interval for oily or corrosive products.
Can plastic slat chains be washed with water?
Yes. POM and similar plastic chains tolerate wash-down, but keep water away from motors and controls and make sure the detergent is compatible with the plastic.
