Abstract:

This paper analyses the way to enhance the separation efficiency of the mechanical movable sieve jigging, researching the mechanical movable sieve jigging technology and process parameters form the quick-return degree of emergency power, dual source power drive, accumulator design and intelligent control system. Introduced the JLT1.6/3.2G efficiency mechanical movable sieve jigging is applied of industrial at Jinwantong Coal Preparation Plant in Shaanxi province, field application research shows: feed size form 50mm to 200mm, separation density is 1.955 g/cm3, imperfect degree is 0.080 and number of efficiency is 96.96%, compared with conventional mechanical movable sieve jigging machine, the efficiency mechanical movable sieve jigging have the ability to adapt the changes of raw coal and stability of the separation indicators.

Key words: mechanical movable sieve jigging, quick-return characteristics, technical feature, application research
