Conveyor belt primary cleaners

Conveyor belt primary cleaners

The right cleaner lasts longer

The purpose of primary cleaners is to remove any coarser material that’s stuck to the conveyor belt after it leaves the head pulley, and to keep the belt as clean as possible. An optimal primary cleaner will be determined primarily by the application and all its parameters.
How to reduce belt wear, prevent component failure and avoid carryback?
An e-book presenting the main tips for avoiding stoppages and failures.

Selecting an optimal primary cleaner

In the majority of cases, the primary belt cleaner is positioned on the head pulley, which is where the material leaves the belt.

Metso supplies different sizes of conveyor systems depending on the volume of material to be conveyed. Belt speed, belt size and pulley diameter all vary.

We do not classify our solutions according to industry segments, but rather according to the application within the segment. That’s because we’ve noticed 70% - 80% of conveyors used in mining are at the smaller end of the scale, even though this is where you also find some of the biggest conveyors. In other words, the application counts more than the industry.

Whether you need the very smallest solution (with cleaners of 1 kilo) or the very biggest (with cleaners of 20 kilos) or something in between the two, Metso has a product for you.

Primary cleaners - Selection quide 

Follow these steps to find an optimal primary cleaner for your application.

  1. Find the relative size of a cleaner by looking at the image below. All the cleaners are in a numerical order. The number is the same in the image as in the table below. 
  2. Find the belt width, belt speed and pulley diameter of the conveyor in the table.
  3. If you end up with more than one option, refine your selection by checking the material and application that is being conveyed in the table.
  4. If you are unsure, please do not hesitate to get in touch with Metso experts.

If the application temperature is above 70°C or below -30°C, the type of the belt spice is not vulcanised, or the belt is reversing instead of one-way, please contact your Metso representative.

Please note that you can contact us by using "Mining" and "Aggregates" contact forms on this page even though your application would be in a different industry.

Trellex ABC-ONE90 primary cleaner's properties and features

The ABC-ONE90 is suitable for many applications in construction (mediumduty, e.g. limestone) and mining (light-duty, e.g. sand and gravel).The tensioner/mainframe is compatible with our ABC-ONE70, and the product is also compatible with a huge installed base of other manufacturers’ cleaners and mainframes.

Material properties

This basic standard product is made of two polyurethane materials, only one of which is in contact with the belt. The stronger polyurethane makes the product structurally stable, so it does not need steel inserts.

Special features

The cleaner’s serrated edge ensures the tool stays sharp to the end of its service life. At that point, you can dispose of the tool safely simply by incineration, without needing to separate any steel.

Trellex ABC-ONE70 primary cleaner's properties and features

Trellex ABC-ONE70 is suitable for use with iron ore, crushed granite or materials that stick to the belt, such as clay. The tensioner/mainframe is compatible with our ABC-ONE90, which gives you the flexibility to change cleaners if necessary.

The ABC-ONE70 is also compatible with a huge installed base of other manufacturers’ cleaners and mainframes and, due to dual hardness, offers an even longer lifetime.

Material properties

Designed with a combination of materials to give you an effective, stable cleaner with a long service. The soft edge is made of a special kind of polyurethane that has been engineered specifically for use in belt cleaners.
This part is moulded to a harder section, consisting of a more rigid polyurethane, that gives the cleaner its firm structure.

Special features

The cleaner’s dual-hardness function (the so-called ‘spatula effect’) is patented. This combination of softness and strength makes Trellex ABCONE70 the world’s best cleaner for highly abrasive materials. The softness
of the material in contact with the belt allows it to adapt to the surface contours (even if the belt is old and worn), thus minimising wear.

Trellex ABC70 primary cleaner's properties and features

The ABC70 is suitable for applications with materials that are very abrasive (e.g. iron ore) or tend to adhere to the belt (e.g. clay). The combination of softness and strength is the world’s best for these kinds of applications in this size category.

Material properties

The ABC70 is made of two different kinds of polyurethane. The soft blue edge is specially engineered for use in belt cleaners, where greater softness extends the service life.

The edge is moulded to the much harder yellow part, which provides structural strength and rigidity. The result is a stable, long-lasting and effective cleaner.

Special features

The cleaner’s dual-hardness function comprises a desirable combination of softness and stability that delivers an extended service life because the softness of the material helps it conform to the belt surface.

The cleaner edge is serrated to ensure the tool stays sharp to the end of its service life. The product is segmented rather than continuous, enabling the segments to move individually and making it easy to join them together.

The tensioner and mainframe are compatible with our ABC90 and ABC95, so you always have an option to test other polyurethane materials if necessary (e.g. a 90 shore material would be sufficient during a dry period).
