Performance difference between plastic roller and other roller
The roller is an important and vulnerable parts of belt conveyor with large consumption. The quality of the rollers determines the service life and energy consumption of belt conveyor. There are many kinds of roller in the market; according to the material, there are metal roller, ceramic roller, and plastic roller.
Which roller is better and more suitable for belt conveyors? Let's make a comparison of the three types of rollers.
Plastic roller is a winding linear molecular structure, especially the ultra-high molecular weight polyethylene roller molecular chain is particularly long, so its impact strength is extremely high. Can withstand repeated shock, vibration, in the long run is not easy to break. The impact of the metal roller is good, but cannot repeatedly shock the vibration, so that metal roller easy to corrosion fracture. Ceramic roller impact resistance is poor, easy to break.
Plastic roller friction coefficient is small (only 0.1 ~ 0.15), high self-lubricating, will not cause wear on the belt, the belt life extension of 1 to 2 times. Because the plastic roller itself is wear-resistant, self-lubricating, the friction coefficient is small, has the super anti-adhesion ability, so the roller surface will not stick and accumulates the material, enhances the host movement smoothness, reduces the material jitters Down, and significantly reduce the noise of the machine, you can make the belt conveyor to achieve long distance, large volume, high speed operation. To achieve the operation of small help, low noise, wear resistance, non-stick material, smooth operation, long roller life, is the traditional roller 2 to 3 times. But also to eliminate or reduce all kinds of accidents, improve safety performance. Metal roller is easy to rust, friction coefficient (0.68 ~ 0.8.) easy to stick material, so the operation of large, high noise, easy to wear, smooth operation, low service life. Ceramic roller is not easy to adhere to the material, the friction coefficient, poor impact resistance, so easy to wear, high noise, low stability, short service life.
Plastic roller with metal roller is not resistant to a variety of chemical medium corrosion, anti-magnetic, wide temperature (-100 ℃ ~ 80 ℃ between the work), health non-toxic food and drugs can be exposed. So the plastic roller is not only suitable for general production occasions, and in the noise, corrosive, non-toxic and other non-toxic industries can also be used. Plastic roller, ceramic roller as the metal roller is the hardness, high prices. Plastic roller, metal roller, ceramic roller water absorption is small. The weight of the plastic roller is the lightest, with a variety of excellent performance, easy installation and maintenance-free. Metal and ceramic roller heavy, a poor performance, installation, maintenance workload
The superior performance of the plastic roller, (plastic roller in the ultra-high molecular weight polyethylene roller performance is the best.) Highlights the plastic roller life than the metal roller, ceramic roller extension 2 to 3 years, the number of replacement maintenance Reduce, that is, to reduce the labor intensity of the staff, but also to reduce the maintenance costs of equipment and improve efficiency. It’s more suitable for belt conveyor.
