Custom Urethane Wiper for your Belt Cleaning Systems
Secondary lightweight belt sweeper is a 100% polyurethane blade with a simple, lightweight construction for cleaning low belt speeds and small loaded belt systems. It can effectively clean conveyor belts while protecting the cleaner blades from damage and not causing damage to belt joints. It is also more flexible in terms of mounting position than older belts and can be mounted directly under the pulleys.
Secondary heavy duty belt sweeper is a tungsten carbide blade fixed to polyurethane. The compact design allows for installation in tight spaces and the long, narrow profile prevents material buildup. Suitable for high speed, heavy duty belts.

Polyurethane sweeper for De-water Cleaning
The flexible polyurethane blade of the de-watering cleaner is like an eraser, which effectively removes backfeed and residual water from the unevenness of the belt surface without damaging the belt. The de-watering sweeper is made of polyurethane knives, which are imported polyurethane material. It is suitable for high moisture content material working condition, and it can deal with the residual moisture of water spraying and collect the moisture effectively.
How do I choose the right size of conveyor belt wiper blade?
There are several key factors to consider when choosing the right size of conveyor belt wiper blade:
- 1. Conveyor belt width: This is the most important factor in determining blade size. The length of the blade should match the width of the conveyor belt, usually the blade length should be slightly larger than the width of the belt, 5 - 10 cm longer is generally recommended. This ensures that the blade can completely cover the width of the conveyor belt during operation, effectively removing moisture, impurities, etc. from the conveyor belt. For example, if the width of the conveyor belt is 80 centimeters, the length of the wiper blade can be 85 – 90CM.
- 2. Installation space: In addition to the width of the conveyor belt itself, it is also necessary to pay attention to the installation space of the wiper. Make sure that there is enough room for the selected blade size in the mounting position. Some equipment may have obstacles or space constraints in the installation area, which requires us to select a blade size that meets the cleaning needs while allowing for a smooth installation.
- 3. Belt Wiper Model: Different models of conveyor belt wipers will have different designs and configurations, and will not have the same suitability for blade size. Some wipers may have specific blade size specifications, so when selecting the blade size, refer to the wiper product manual or consult the supplier to ensure that the selected blade can be perfectly adapted to the wiper.
