PUR blades < Tungsten carbide blades


Image1222 (2).png

Polyurethane is soft enough to let some fine dust pass in between blade and belt

​Tungsten is hard and offers a cutting edge able to stop smallest particles


Polyurethane wears out faster so it needs to be bigger and move a lot during its lifespan (bigger and more complex tension system)

lame Z² regular tungsten ususre.PNG

Tungsten carbide wears out much slowler so the blades can be smaller and doesn't need a lot of movement.

It also lasts longer and reduces interventions

Smaller blades and tension system are easier to install

Short movement needs less maintenance and simplier tension system

Less frequent replacement reduces maintenance and spare parts stock

Tungsten carbide blades < PUR blades

Damaged belts


​Tungsten is hard and sharp and can shave chips from damaged belt surface

Polyurethane is soft and doesn't cut damaged belt

Less danger

Impacts / Mechanical lacing

Tungsten carbide can break under impacts becoming cutting and dangerous for the belt surface.

It can also becomes friable and so lasts a shorter time

(Impact resitant tungsten carbide exists but has shorter lifespan)

Image2 (6).png

As an elastomere, Polyurethane is unsentivive under impact

 No danger or lifespan reduction

Cleaning liquids

Tungsten carbide is hard and can't adapt to slight irregularities of the belt surface to stop liquids

Polyurethane is soft and offer a better seal-contact to stop liquids

Better drying effect

Sintered alumina blades < Tungsten carbide blades


May wear off with rounded edge

Always offers sharp cutting edge

Some uncommon acids can corrode it

Cleaning efficiency never drop

Tungsten carbide blades Sintered alumina blades

Chemical resistance


Special qualities of tungsten carbide exist to sustain chemical aggression or to be food grade quality but can be expensive due to low quantity or specific compounds


Standard quality Sintered alumina is very resistant against chemical aggression and is food grade

PUR < Rubber

Hydrolysis resistance


Standard MDI Ester PUR doesn't resist against hydrolysis and requires to be replaced by more expensive MDI Ether

Standard natural rubber has not sensitivity agaisnt hydrolysis with cheap cost


ST PU r1.png

PUR offers less friction

For tracker this meeans less centering effect, water may cause even poor friction

Compensation low friction with more pressure is dangerous since PUR has less elasticity and can break easier


Rubber offers more friction

For tracker this means more centering effect

Rubber < PUR

Abrasion resistance

abrasion 120 201.png

Standart rubber quality offers ±120mm³ abrasion resistance

Very good  rubber can offer 50mm³ with expensive price

Standart polyurethane quality offers ±20mm³ abrasion resistance

Possible to reduce even more to 12mm³ with moderate extra cost

Oil resistance


Natural rubber (and some sunthetic) can be damaged by oil, grease and hydrocarbons

PUR is perfectly resistant to oil, grease and hydrocarbons

Patterned ceramic < Porous ceramic

Friction over time

As the spikes reduce due to wearing, the transmission created by micro gearing decreases and disappear

Spikes are never higher than 2,5mm

Regardless of the level of wear, the friction stay the same

Obtuse cleaning angle < 90° cleaning angle


Needs nearly perfect surface, can be dangerous if no secure pressure system (sometimes not enought like hole in belt) 

Can increase belt cracks or damage extra thickness splicing

Clean any kind of surface, new or old belt, nearly never any danger

Secondary cleaner < Primary cleaner


prim sec 3.png

Secondary cleaners are installed in reduced space (hopper edge, tension pulley, limited high...) sometimes not available

Primary cleaners are installed in more free space nearly always available

Scraped material

prim sec 4.png

Secondary cleaners could require to modify the hopper entrance and/or could have clogging issue

prim sec 1.png

Primary cleaners realse scrapped material directly into the flow

Primary cleaner < Secondary cleaner

Installation adjustement


Primary scraper can be difficult to adjust properly because the angle is a efficiency key point easy to miss (especially with tungsten carbide)

If the adjustement is not correct <90°, it can also leads accident of upturned cleaner (without security) and scratched belt 

Secondary scraper are quite easy to adjust

If the adjustement is not correct, there is nearly no risk of damage


Primary cleaners are put in pressure directly on the head pulley

Therefore it's not possible to apply an important pressure

Secondary cleaners give pressure in a free space zone of the belt and can have higher pressure


pulley shape.png

Primary cleaner are not compatible with special shape pulley (SlideLag, squirrel cage pulley, etc...)

Secondary cleaner are compatible with any kind of pulley shape

Mono-blades < Multi-baldes

Unflat belt

Image10 (2).png

Mono-blades are not able to adapt their shape to not plane belt

This offers a uncomplete cleaning and quick wear zones


Multi-blades can adapt their shape to any kinf of belt

This cleaning is complete

Stuck particle

Image2 (2).png

​If a particle comes in between the belt and the cleaner (punch in the belt), the complete mono-blade cleaner can be off from the belt​

The cleaning is no more efficient

​If a particle comes in between the belt and the cleaner (punch in the belt), only one blade of the multi-blade cleaner can be off from the belt​

The cleaning continues

Blade cost

ext (23.jpg
multi change partiel1.png
multi change invert 1.png

When the center of the mono-blade cleaner is worn, the complete balde has to be changed

Image39 22.png

In case of accident, the complete blade has to be changed

When the center of the multi-blade is worn, you can change only the needed blades

You can also invert the center and sides blades at mid-life to delay the need of spare parts

Image8 (2).jpg

In case of accident, it's easy to change only the damaged blade

1 axis multi-blades < 2 axis multi-baldes


multi 1 axe.png
multi 2 axes.png

When multi-baldes move "back and forth"only , they can have difficulty to adapt to some irregular shape 

Multi-blades with "back and forth" + "pivoting" can offer greater adaptability

Multi-blades < Mono-blade


Materials can pass inbetween multi-baldes

Mono-balde offers slightly better cleaning


Multi-blades are not compatible with paper, wire or fabrics. Blades can stay stuck together with some material (ex: sugar)

Mono-blade is perfect for recycling and sticky material


Multi-blades can suffer from holes or patches or can damage the belt even greater

Mono-blades has very reduced danger with holes and patches

Outgoing belt

Image1 (2).png

If the belt move too far on side, multi-blades can go out of the belt with possible damage 

- on the pulley lagging

- on the outside blade

- on the edge of the belt

The belt could also have difficilty to go back to center position

Mono-blades are not concerned by the movement of the belt

Blade(s) replacement

multilame reglage 2.png

On blades replacement, multi-blades require one by one adjustement

sw lame out.png

On blade replacement, no adjustement required

Without compensation < With compensation


Image15 (2).png

Belt cleaners without compensation quickly lose cleaning efficiency and requires high frequency blades replacement

Belt cleaners with compensation maintain cleaning efficiency and reduce blade replacement


Image23 (2).png
demo comp r3 2.png

With gap emergence, materials can be stuck inbetween the cleaner and the belt,   accumulate and push aside the cleaner and can make scratch on the belt 

With permanent contact, no danger of material stuck

No blade security < Blade ejection security

In case of accident without ejection security, blade(s) and support can be definitely damaged and can damage the belt by being stick in abnormal shape and position

Image8 (2).jpg

In case of accident with ejection security, no damage to the belt or cleaner support

The blade can also sometimes be recovered and reinstalled

Complex flow < Direct flow


If the cleaned material has to encounter the cleaner structure due to complexity or size, it can easierly built up and completely clog the cleaner


Simplified shape and small size make short flow on the cleaner greatly reduce the danger of clogging

Complex assembly < Simple assembly

Parts and bolts


Big quantity of parts increase the risk of mistake

Presence of bolts under the belt increase the risk of bloking since the cleaner is in the dirtiest place of the conveyor

Limited parts reduces the risk of mistake 

No bolts under the belt and nested blades prevent the risk of blocking



Necessity to take time disassemble several parts to remove the cleaner

Big cleaner size makes it harder to install and to take out for maintenance

Big tension system use more parts and require more space

QL opened.png

Quick opening and remove of the cleaner

Small cleaner size makes it easier to install and to take out for maintenance

Compact or integrated tension system is simplier and require less space

Medium durability < High durability

Blade wear area


2x10 or 3x10

Tungsten carbide

Smaller wear area means smaller lifetime



Tungsten carbide

Bigger wear area means bigger lifetime


Unprotected structure has shorter lifetime


Painted structure

Protected structure has bigger lifetime


Zinc platted structure








RacloFlex N

Elastomer part is crucial and should be big enought to absorb vibration and keep correct elasticity for a long time

Passive belt retention < Active tracker

poupée 2.jpg
STARtrackerauge 2012.jpg

Passive belt stopper can only manage light outgoing and can damage the belt

Active belt tracker gives a force to center the belt

Edge contact < Surface contact

Belt tracker detecting belt edges contact  only react after a minimum side movement 

centreu 1.jpg
centreur 2.png

Belt tracker with belt position detection react all the time

Contact with belt edges can cause accident (Especially if edges are damaged due to previous belt outgoing)

Surface contact avoid accident

Different products < 1 unique product


Many belt tracker are designed only for :

- return belt 1 way

- return belt 2 ways

- carrying belt 1 way

- carrying belt 2 ways (very few solution)

wich makes more complex the maintenance management


Only 1 product for :

- return belt 1 way

- return belt 2 ways

- carrying belt 1 way

- carrying belt 2 ways

is much simplier

Big spare < Simple spare

faux trutrac.png
STAR spare.png

When the belt tracker needs a big spare part, the replacement can be complex and expensive

When the belt tracker needs small and simple spare parts, the replacement is quick and cheap

Idlers < Impact bars

Belt shape

Because idlers are ponctuals support, the belt can have a sinusoidal shape

If the skirt doesn't follow this shape, material can easely go out of the conveyor or even make damage on closing angle


Impact bar make the belt flat and easier to seal

Impact resistance

Idler have ball bearings wich can be damaged by impacts stopping the rotation

- With Rubber rings: brakes the belt (power consumption, temperature rising, decentering)

- Bare steel: becomes dangerous cutter

Impact bar are static parts without damage risk, only wearing

Standard impact cradle < Tailor made Impact


Standard impact cradles have many adjustement requiring many weak points (articulations, position bolts)

Tailor made impact cradles are designed exactly to fit the target conveyor without ajsustement and can be much stronger


berceazu concurrent reglable.png
atlas install.png

Standard impact cradles requires adjustments making longer installation

Some charateristics (ex:heigh, base width) are not adjsutable and could requires huge adaptation on the conveyor

Tailor made impact cradles are quick and easy to install

Special design

Image1 berceau droit.png

Standard impact cradles only offers regular shape

Tailor made impact cradle can be produced in transition shape required to install in transition zone close to the tail pulley
