The roller is an important part of the belt conveyor. It has many kinds and large quantity, and can support the conveyor belt and material weight. 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. There are two kinds of rollers: steel and plastic.
FEATURES AT A GLANCE
1.Radial circular runout: the radial circular runout shall not be greater than the defined value in Table 1 below. 2. Axial channeling: Under the axial load of 500N, the axial channeling momentum of the roller shaft is less than 1.2mm. 3. Rotating resistance: when the roller is under the pressure of 250N and the outer velocity is 2.0m/s, its rotating resistance is less than the defined value inTable
