The cleaner plays a role in cleaning the belt, effectively preventing material adhesion to the belt, and creating a clean and environmentally friendly conveying environment for enterprises. But some newly purchased cleaners by companies are damaged shortly after use, and the blade area is severely worn, not only failing to achieve the expected effect, but also affecting production efficiency. Today, we will analyze the actual working conditions to help you identify the reasons for the rapid wear of the blades.
In the belt cleaning system, the tensioning device is a crucial part, and only by maintaining the appropriate pressure of the blade edge on the belt can better cleaning results be achieved. If the tension is too high, it will increase the friction between the blade and the belt, leading to premature wear of the blade. If the tension is too low, too much adhesive will be sandwiched between the high-speed running belt and the blade, causing serrated wear of the blade.
Another reason for the rapid wear of blades is the prolonged idling of the belt, which often contains moisture during transportation, which can provide lubrication and cooling to the belt. However, during idling, the surface of the belt is too dry, and the embedded small particles of material will continuously rub against the blades, increasing the wear rate of the blades.
Another potential source of wear is that the material temperature exceeds the allowable range of the blade temperature. When the belt speed increases significantly, the heat inside the blade will continue to accumulate, causing a decrease in its strength and causing damage.
In addition to the external factors mentioned above, inaccurate material selection or installation of the cleaner can also lead to rapid blade wear.
We should choose the appropriate cleaner based on the width, speed, and diameter of the front drum of the on-site belt. The cleaning tool holder can be equipped with a buffer compensation mechanism to facilitate the passage of protruding materials. The blades can be made of polyurethane composite materials or alloy rubber blades, which have the characteristics of low friction coefficient, good wear resistance, and moderate hardness. They have good follow-up performance for various belts and can reduce unnecessary wear of belts and blades.
In addition, under complex and ever-changing working conditions, only by making accurate selection, correct installation, regular maintenance and adjustment of the cleaner can it effectively avoid rapid wear and tear, fundamentally reduce material adhesion and leakage, and provide a good foundation for subsequent work.
