Rolo transportador de correia são componentes importantes do belt conveyors, there are many types and large quantities. It accounts for 35% of the total cost of a belt conveyor and produces more than 70% of the resistance, so the quality of the roller is particularly important.
Os rolos transportadores são compostos por várias peças: caixa, eixo, rolamento, vedantes e encaixes. Os nossos rolos transportadores mecânicos apresentam uma estrutura única, componentes fiáveis, montagem precisa, elevada capacidade e longa vida útil.
The primary function of the rollers is to support the weight of the conveyor belt and its load. They must be flexible and dependable. Rollers help reduce belt running resistance and maintain the verticality of the belt, ensuring smooth operation. Reducing friction between the conveyor belt and the rollers is vital for extending the belt's lifespan, which constitutes over 25% of the total conveyor cost.

This standard idler design is commonly used in most heavy-duty conveyor applications. Darko manufacturer make the rollers from steel and often coat them with multiple layers of specific paint, rubber, or other anti-corrosive materials.
Os rolos podem ser de aço, revestidos com várias camadas de uma determinada especificação de tinta, ou revestidos de borracha ou de outros materiais anticorrosivos.
Séries de rolos e aplicações
These rollers are particularly suited for conveyors operating in challenging conditions, where working loads are high and large lump sizes are conveyed. Despite these demands, they require minimal maintenance. Typical applications include mines, cimento obras, centrais eléctricas a carvão e instalações portuárias.
The roller sealing system effectively addresses environmental challenges such as pó, dirt, water, and extreme temperatures. Standard greased components function well within a temperature range of -20°C to +100°C. For applications outside this range, special grease, bearings, and seals can be used.
