NSE bucket elevator design ABSTRACT The task is to study the design of bucket elevator NSE working principle, performance and features, using the method of integrating theory with practice, study the impact of bucket elevator efficiency factors, carry out the necessary structural improvements to the program structure and implementation of design. At the same time, the relevant structural parameters and process parameters of the design and calculation, the all over program design, the general assembly, as well as transmission, body parts and related parts and components such as design and graphics. Design options are as follows:  (1) bucket elevator to the working principle of an in-depth study, in accordance with TH250 bucket elevator capacity and use of the work requirements of the overall program design.  (2) design a reasonable hoist the strength of the structure and components to ensure stability.  (3) design a reasonable drive to ensure the efficient operation.  The bucket elevator with throughput, and enhance the high degree of high, stable and reliable, easy operation and maintenance, long life and other significant features. Bucket elevator for conveying powder, granular and small block of low-wear properties of cut, material packing density of less than 1.5t / m, material temperature does not exceed 250 ℃, is widely used to enhance cement machinery.
