Dec 13, 2019 Basic Conveyor Calculation Mass Flow Rate In the construction and calculation of a belt conveyor the first step is the calculation and determination of the general size of the conveyor. If bulk material should be conveyed from one place to another the daily mass flow is often given from other parameters of the plant. Material flow rate The conveyor system is basically calculated by
Hans Renold in 1880. Later the principle was applied to conveyor chain giving the same advantages of precision, heat-treated components to resist wear, high strength to weight ratio and high mechanical efficiency. Renold conveyor chain is made up of a series of inner and outer links. Each link comprises components manufactured from
