Conveyor belt tensioners

Conveyor belt tensioners

Metso tensioners ensure your cleaners stay in place

Several parameters affect the cleaning efficiency of your conveyors. For example, the contact angle between cleaner and belt, the contact area, and the pressure. Metso's conveyor belt tensioners work with the belt cleaners to maintain the correct pressure and thereby optimise your cleaning function.

Conveyor belt primary tensioners

Conveyor belt primary tensioners

Several parameters affect the cleaning efficiency of your conveyors. For example, the contact angle between cleaner and belt, the contact area, and the pressure.

When the primary cleaner blades are kept securely in the correct position, these values remain at an optimal level throughout the wear life of the blades, which significantly enhances the efficiency of your primary cleaning function. Furthermore, the required maintenance is minimized since there is no need to re-tension the spring.

Metso tensioners are made to ensure that your cleaners stay in place. Their springs are enclosed to improve health and safety and minimise the risk of operator injury.

Properties and features: Trellex ABC O

Trellex ABC O-Tensioner-L is designed for light- to medium-duty applications. It is recommended for use especially with Trellex ABC-ONE90 and Trellex ABC-ONE70 primary cleaners. 

Material properties

Built of 8 mm galvanised steel, this robust tensioner has a long service life. For operations involving aggressive materials such as salt or fertilizer, stainless steel can be requested.

Special features

Thanks to compact design and variety of possible positioning options, Trellex ABC O-Tensioner-L can fit onto almost any kind of conveyor.

The spring is encapsulated to protect it from damage, dust and dirt. It is easy to install and maintain and does not require re-tensioning during the blade’s wear life, which saves you time and effort and keeps unscheduled stops down to a minimum. Encapsulation also eliminates the risk of operators injuring their hands in the pinch point.

Trellex ABC S - Tensioner - L/M properties and features

Trellex ABC S-Tensioner - L/M is made for light and medium-duty applications. Suitable for use with pre-cleaning cleaner blades, this tensioner provides the right pressure to optimise the belt cleaning function. 

Material properties

Built of 8 mm galvanized steel, this robust tensioner has a long service life. Also available in stainless steel, on request.

Special features

The spring is encapsulated to protect it from damage, dust and dirt. It is easy to install and maintain and does not require re-tensioning during the blade’s wear life, which saves you time and effort and keeps unscheduled stops down to a minimum.

Encapsulation also eliminates the risk of operators injuring their hands in the pinch point.

Trellex ABC L - Tensioner - H properties and features

Designed for medium and heavy-duty applications, Trellex ABC L - Tensioner - H provides the right pressure to optimise the belt-cleaning function. It is often used with the largest and toughest pre-cleaning cleaner blades. 

Material properties

Made of powder dip-coated steel, up to 15 mm thick, this robust tensioner has a very long service life. It can even withstand the impact of heavy rocks bouncing back up from the chute.

Special features

The spring and the rotation disk in this tensioner are joined by a wire, which is 5 m as standard but can be much longer if necessary.

This means that if your installation point is hard to access, the tensioner can be placed on the service platform at a distance from the rotation point, and it is still easy to adjust the pressure.

Trellex ABC LX - Tensioner - H properties and features

Designed for heavy-duty applications like hard rock mining, Trellex ABC LX-Tensioner - H is generally used with the largest pre-cleaning cleaner blades to provide the right pressure to optimise the belt-cleaning function.

Material properties

Made of powder dip-coated steel, up to 20 mm thick, this robust tensioner has a very long service life. It can even withstand the impact of heavy rocks bouncing back up from the chute.

Special features

The spring and the rotation disk in this tensioner are joined by a wire, which is 5 m as standard but can be much longer if necessary. This means that if your installation point is hard to access, the tensioner can be placed on the service platform at a distance from the rotation point, and it is still easy to adjust the pressure.

A unique, optional feature of this tensioner is the antirollback device. Placed on the rotation axis, it prevents the blade from aquaplaning and being pushed away from the belt.

Conveyor belt secondary tensioners

Conveyor belt secondary tensioners

When the secondary cleaner blades are kept securely in the correct position, the contact angle between cleaner and belt, the contact area, and the pressure remain at an optimal level throughout the wear life of the blades, which significantly enhances the efficiency of your secondary cleaning function.

Proper secondary tensioners also minimize the required maintenance since the blade-to-belt contact pressure is stable throughout the blade’s lifetime, and the need to re-tension the spring is eliminated.

Trellex ABC Z - Tensioner - L/M properties and features

Trellex ABC Z - Tensioner - L/M works with secondary cleaners to maintain the correct pressure and thereby optimise your secondary cleaning function.

Material properties

The standard material is 8 mm galvanised steel, but it is also available in stainless steel on request, for use in more aggressive applications.

Special features

The Z-Tensioner is a flexible, hardwearing product with a smart, space-saving design. It includes several features for easy installation and blade changes.

For example, a slide-in/slide-out system that makes it quick and easy to replace the blades, and safe for operators. It can be installed inside or outside the conveyor chute and tightened from above or below.

The Z-Tensioner’s compact design minimises the risk of contact with motor or gearbox, and an encapsulated spring protects from damage, dust and dirt – thereby also reducing maintenance and increasing wear life.
