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
