Role of Conveyor Rollers in Mining Industry LinkedIn
One of the most important components of a belt conveyor system is the conveyor roller. These rollers are responsible for supporting the weight of the materials Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit'Coal mining
