Technical parameters
Generally, the main parameters are determined according to the requirements of material handling system, various conditions of material loading and unloading location, relevant production process and material characteristics. (1) conveying capacity: the conveying capacity of the conveyor refers to the amount of material transported within unit time. When conveying bulk material, calculate by the mass or volume of material transported per hour; When conveying a finished article, it is calculated by the number of pieces transported per hour.
