Basic Information


Several solutions for lubrication applications



Comprehensive range of conveyor lubrication



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!

Chain Lubrication in the Food & Beverage Industry


8

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


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



Chain Lubrication


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


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


Wet Lubrication

Chain Lubrication

Application details


Wet Lubrication

Chain Lubrication

Application details – Advantages:

Easy application

simple concepts

well known, uncomplicated service

reliable product availability, established business model

Added lubrication

conveyor chains on / in conveyor construction

Washing ≠ hygiene

dust and product spillage

Simple „add ons“

cleaning and disinfection, consumption monitoring


Wet Lubrication

Chain Lubrication

Application details – Disadvantages:

high consumption of water and lubricant

aerosols

humidity in production

wet floor (more draining, drip trays)

impact on building structure

hygiene issues (bacteria / biofilm)

slippery floor (working safety)


Semi Dry Lubrication

Conveyor Lubrication


Semi-Dry Lubrication

Chain Lubrication

The mixed approach:

premixed / pre-diluted lubricant

fixed concentration

zoning by solenoid valves – depending on sections of filling line

application mainly with spray nozzles or orifices-plates

variation volume of lubricant on conveyor

on / off control (timing)

different sizes of nozzles (liter / hours)

needle valves

hybrid version with water reduced application for glass



Chain Lubrication

Application details



Chain Lubrication

Application details – Advantages: Easy application

simple concepts

uncomplicated operation

Inexpensive step into dry lubrication

easy retro-fit / change from wet to semi-dry

No water consumption



Chain Lubrication

Application details – Disadvantages: Still drops / puddles on the floor

wet floor

hygiene issues (bacteria / biofilm)

slippery floor (working safety)

No washing effect


Extra Dry (TD) Lubrication

Chain Lubrication


Extra-Dry Lubrication

Chain Lubrication

The real dry approach:

Concentrated lubricant

Fixed concentration

Zoning by solenoid valves – depending on concept

Application brushes or plates

Variation volume of lubricant on conveyor


needle valves / orifice plates



Chain Lubrication

Application details



Chain Lubrication



Lowest lubricant consumption

High flexibility of applied volumes (per conveyor)

optimized line performance

Best product application (brush)

Dry conveyors

low / no bacteria issues

Dry floors



Chain Lubrication


High investment

Business models

Contact application (brush)

dirt trap (collecting dust from conveyor)

Additional application point necessary

No washing effect

Issue with water application (e.g. can shower)


Ultra-Dry Lubrication

Chain Lubrication

The latest dry approach:

Concentrated lubricant

Fixed concentration

Zoning by spray devices – for each track

Variation volume of lubricant on conveyor




Chain Lubrication



Lowest lubricant consumption

High flexibility of applied volumes (per conveyor track)

high frequency

full spray pattern

Contact free application (spray nozzle)

Dry conveyors

low / none bacteria issues

Dry floors



Chain Lubrication


High investment

Limited range of lubricants (viscosity)

No washing effect

Business model
