Method for improving crushing vibrating screening efficiency

Abstract

The invention discloses a method for improving crushing vibrating screening efficiency. The method is suitable for the reformation of a dual-layer circular vibration screening machine and a dual-layer linear vibration screening machine, and aims to reduce the blockage of screen holes, prolong the service life of spare parts and reduce a failure rate. In the method of the invention, an inclination angle of a screen cloth is reduced; the level elevation of the lower part of a vibrating screen is kept unchanged; the installation height of the upper part of the screen cloth is reduced; the climbing angle of a feeding belt conveyor is reduced to 0 degree to form a horizontal belt conveyor for feeding; the feeding speed and the ore feeding amount of the conveyor are determined according to the operation load of the vibrating screen; the feeding speed and the ore feeding amount of the conveyor are determined according to the thickness of a material layer to be screened by the vibrating screen; the thickness of the ore feeding material layer is 3.8 to 4.2 times of the width of the screen holes; and the screen cloth is fixed on the two sides of a screen box by utilizing spring hooks on the two sides of the screen cloth.

Description

technical field [0001] The invention relates to a method capable of improving crushing and screening efficiency. Background technique [0002] Vibrating screening machine is a common ore size screening equipment after iron ore crushing, and it is the check equipment for the final ore particle size in the grinding process. However, vibrating screens often have low screening efficiency and screen hole blockage during production and maintenance. The structure of the cement beam under the screen is redundant, the ore discharge is not smooth, the dust is large, the thickness of the material on the screen is uneven, the center of gravity of the vibrating screen is high, there are many machine failures, and the load is uneven, resulting in a large cycle load of the original crusher and uneven force. The ore breaking efficiency is low, the machine vibrates greatly, the ball mill enters the grinding particle size and other problems, and the maintenance cost is high, the operation is ...
