Application
Chain lubrication is supposed to adjust the coefficient of friction between product container (bottle, can, packaging board, …) and conveyor track.
Fr = µ x Fn
Not minimizing but optimizing!

Coefficient of friction
Range of optimal friction is nearly the same.
Packaging (bottles / cans) Optimal friction value
PET 0,08 – 0,12
Glass 0,08 – 0,12
Glass, transport 0,10 – 0,15
Aluminum cans 0,08 – 0,12

Chain Lubrication
For chain lubrication friction depends on several parameters:
Material combination of container and chain
Size and weight of container (material, empty or full) and center of gravity
Cleanliness of conveyor track / container
Washed or unwashed returnable bottles
Speed of conveyor track
Foot print of the container
Coefficient of friction

Chain Lubrication
Coefficient of friction
For chain lubrication friction is influenced by several parameters:
Lubrication concept (lubricant)
Concentration of the lubricant
Water quality (if lubricant is diluted in water)
Status of the conveyor
Surface condition of conveyor track
Cleanliness of conveyor track (not only in regards of deposits but presence of water)
Design and performance of the filling line (curves, showers, …)
Surrounding conditions (dust, …)

Chain Lubrication Lubrication Concepts
There are several lubrication concepts in the market:
Wet lubrication – the classical approach
Semi-Dry lubrication
Extra-Dry lubrication
Ultra-Dry lubrication

Lubrication Concepts
Chain Lubrication
Wet lubrication – the classical approach Water is mixed with lubricant Typical concentration between 0.06 – 0.5%
use of more dosing pumps allow different concentrations
Zoning by solenoid valves – depending on sections of filling line Application with spray nozzles or orifices-plates Modification volume of lubricant on conveyor
on / off control (timing) different sizes of nozzles (liter / hour) needle valves
