How to use SOAP LUBRICANT for Conveyors?
Below is a practical operating procedure for using RXSOL SOAP LUBRICANT FOR CHAIN CONVEYORS.
This is written for plant / maintenance use.
What is meant by “soap lubricant” for chain conveyors
Typical dilution
For most chain conveyor soap lubricants:
0.5 % – 2.0 % in water
Practical range:
Condition Recommended dilution
Normal indoor conveyors 0.5 – 1.0 %
Long conveyors / high load 1.0 – 1.5 %
Dry environment / high friction up to 2.0 %
Example
1% solution = 10 ml soap lubricant in 1 litre water
Standard operating procedure (SOP)
1. Check the conveyor condition
Before dosing:
- Remove heavy dust, sand or sticky deposits
- If very dirty : wash with neutral or mild alkaline cleaner and rinse
- Soap lubricant must be applied on a clean chain.
2. Prepare the lubricant solution
In a clean mixing tank:
- Fill required water
- Add soap lubricant slowly
- Mix gently (no heavy agitation required)
Important:
- Use soft water if possible
- Very hard water can reduce lubricity
3. Set the dosing system
Use either:
- central lubrication unit
- spray manifold / drip lubrication line
- Set feed so that:
- chain surface becomes slightly wet
- not flooded
- Over-application attracts dust and causes slipping.
4. Apply during running condition
Always apply:
while conveyor is running
Spray or drip onto:
- chain pins
- rollers
- sliding tracks (if plastic or SS bed)
Avoid spraying directly on:
- motors
- sensors
- belts (if mixed system)
5. Allow spreading
After first application:
- Run conveyor for 5–10 minutes
- This allows the soap film to:
- spread along the chain
- penetrate pin / bush areas
6. Adjust to minimum effective dose
Correct condition is:
- chain runs quietly
- no jerking
- no visible dry friction
- no excessive foam or puddling
Reduce dosing until you reach:
- lowest feed rate that still gives smooth movement
Daily / shift operation
Keep dosing ON only when line is running
Visually check:
- chain shine
- smooth travel
- no sticky build-up
Weekly check
Inspect for:
- soap residue on frames
- dirt accumulation
- If residues form reduce concentration or dosing rate
