RETURN BELT CLEANERS
RETURN BELT CLEANERS
Tecnipak’s return belt cleaners are installed immediately before the tail pulley and directly over the return belt.
They operate by removing the material that has landed on the inside of the belt before it reaches the tail pulley, thereby avoiding material getting trapped between the belt and the pulley and contaminating the conveyor belt system. Thanks to their telescopic tensioners, these cleaners can be pushed directly onto the belt, which is why their cleaning quality is dramatically better than that of other return belt cleaners that only rest over the belt because of their weight.
PROTECTED TENSION UNIT
Avoids contamination.
ACME SCREW ADJUSTMENT
Ensures an easy, non-stick adjustment
TWO PAIRS OF TENSIONERS
Allows for different adjustments front and back, improving the performance.
STRUCTURALLY ROBUST
Pipes connected in a rectangle shape make for an excellent support, improving cleaning quality.
STAINLESS STEEL FRAME
Guarantees years of operation without rusting or coating degradation.
• Tensioning consoles. Tecnipak’s return belt cleaners have telescopic tensioning consoles that allow the cleaning blades to be applied directly onto the belt, so that they can really perform and push against the return belt for better cleaning.
• Polyurethane blade. The blade is made out of 83 Shore A hardness polyurethane, which has a much lower sliding resistance against the belt than blades made out of rubber that are usually used in these types of cleaners. Because of this, it is friendlier to the conveyor belt system while at the same time improving the cleaning quality.
• Toughest cleaners available. Tecnipak manufactures the frame of our return cleaners in 2″, 21/2’’, and 31/2’’ pipe. They are the toughest cleaners available, and by making them instainless steel, we can guarantee their performance even in the worst conditions.
• Square-in-square elastomer. The element that delivers the tension is a square-in-square elastomer that acts as a pivot point for the lever arm. This way the tensioner can absorb deviations in the operational conditions, such as splices, misalignment, and repaired belts.
• ACME screw adjustment. The tension consoles have an ACME threaded screw that runs on the inside of the telescopic system for adjustment. This enables it to be adjusted easily and without the need for special tools.
• V-Plow or diagonal. Install a v-plow cleaner for optimal performance, or a diagonal cleaner if operational conditions require the ore to be removed only towards one side of the belt.
• All-around reliability. Every part has been designed and developed to perform with minimal maintenance and a wide tolerance to changes in the working conditions.
SPECIFICATIONS:
- Belt speeds up to 7.5 m/s (1,450 fpm)
- Belt widths from 600 mm up to 3,000 mm (24’’ up to 120’’)
Why are Tecnipak’s return belt cleaners more effective? Return belt cleaners that rest over the belt only exert a force over it because of their weight. This is not effective because the vibrations of the belt make these kind of cleaners vibrate on their own, at times separating them from the belt, which is why they let material through. In addition, they cannot remove ore that has stuck to the belt because they lack the necessary tension to do so.
Tecnipak’s return belt cleaners have tensioners that allow the cleaners to be applied directly against the belt, so that they can truly clean the return belt cover.
This is why even if the belt vibrates, Tecnipak’s cleaners will not let ore pass through and will remove ore even if the material is stuck to the belt. It is for these reasons that Tecnipak’s return belt cleaners offer dramatically better cleaning quality than those from the competition.

FAQ
Should I choose a v-plow or a diagonal return cleaner?
The v-plow is the most efficient cleaner when it comes to protecting the tail pulley from the material that ends up on the inside of the return belt. Thanks to its V shape, the material is pushed quickly to both sides of the belt. The diagonal cleaner, on the other hand, works by pushing the material to just one side of the belt. This is an advantage when pushing the material to both sides is not an option, as can happen in underground mining, for example. So a v-plow should always be favored over a diagonal cleaner, whereas the latter should be installed if a v-plow is not an option.
