Porcelain coated roller (Ceramic)
Ceramic coated rollers (porcelain) are made by using the method of gluing ceramic rubber sheets onto the roller surface. Ceramic coated rubber sheets (porcelain) are a combination of ceramic plates on the surface of a special rubber sheet, according to a certain layout (in squares, fillings, circles…) by advanced hot vulcanization technology.
The biggest difference in ceramic coated rollers of 75 Rubber Co., Ltd. is the hot vulcanization method, which instantly molds ceramic rubber sheets onto the roller surface instead of using cold glue technology. Therefore, the bond between the ceramic rubber layer and the roller reinforcement ensures high homogeneity, withstands great tension on the surface and greatly increases the life of the roller.
Ceramic coated rollers have outstanding advantages, including:
- Specially structured and arranged ceramic plates are incorporated on a characteristic rubber base that increases the coefficient of friction between them and the conveyor. Minimize sliding friction between roller and conveyor, minimize conveyor slip during operation.
- The high wear resistance of the ceramic surface is applied to the drive roller of the conveyor system, making the service life of the drive roller much longer than that of the traditional rubber coated roller.
- Especially in conveyor routes with high conveyor speed and long belt length, under the same load, ceramic coated rollers will reduce conveyor tension and prolong conveyor life compared to high coated rollers. su.
- Reduces conveyor belt deflection and wear during operation.
- Each ceramic rubber sheet has grooves at a certain distance, which can cause foreign substances (dust, soil, materials…) to stick on the roller according to the groove, so the roller has a unique self-cleaning function, Especially suitable for wet working environment.
- Improve operational efficiency, make the roller and conveyor run synchronously to ensure the conveyor operates efficiently and withstands large loads.
