香蕉筛新型螺杆筛面的设计与研究

his article bases on the study of the congestion problem of 300 mm sieve hole emerging during the process of the CONN-WELD banana screen uses in NewJulong coal preparation plant, and puts forward a novel kind of scheme could solve the problem of big materials jam mesh, The scheme involves the design of a new type banana screen's screw sieve screen surface.This paper mainly introduces two process of the screw sieve screen surface of banana screen's schematic designand technical design. Finally, to experimentally study of the work effect of the banana screen designed by us.To put it to test with a simple device during the design process, based on the test results, we tried to optimize the design, finally, a kind of screw sieve which could be used to solve the blocking problem was designed.
