Problems solved by technology

It solves the problems of the existing mineral screening device that the screen holes are easy to wear and the screen holes are easy to be blocked, which leads to the change of the screening effect over time and the low screening efficiency, the secondary pollution caused by the screening device, and the inability to obtain data from the screening results. the problem of

Embodiment

[0039] Such as figure 1 As shown, a mineral particle size screening mechanism includes from top to bottom: a number of screening devices 1, and the screening devices 1 are arranged at intervals, and each of the screening devices 1 is arranged horizontally and connected by a support frame Placed on the ground, if only one screening device 1 can be directly placed on the ground; each of the screening devices 1 includes a number of axles 11 and baffles 13, and each of the axles 11 is evenly spaced on the baffle 13 Above, the axles 11 rotate around their axes and in the same direction (uniformly turn to the right or left), and the distance between the axles 11 of the screening devices 1 gradually decreases from top to bottom. . Rotate in a unified direction like this so that the minerals screened out on each layer of wheel shafts can be collected from the same direction, and the gap between each of the wheel shafts 11 of the screening device 1 at all levels from top to bottom gra...

Abstract

The invention relates to a mineral particle size screening mechanism. The mechanism sequentially comprises a plurality of screening devices from top to bottom, and the screening devices are uniformlyarranged at intervals; each screening device comprises a plurality of wheel shafts and baffles, each wheel shaft is uniformly arranged on each baffle at intervals, the wheel shaft is wound around theaxis of the wheel shaft correspondingly and rotate in the same direction, and the distance between the wheel shafts of each screening devices is gradually reduced from top to bottom. According to themineral particle size screening mechanism, the distance between the wheel shafts replaces existing sieve holes to carry out screening, so that the effect of automatic screening can be realized, meanwhile, screened minerals are counted and recorded, and minerals which do not meet the requirements are returned for processing; and the mechanism solves the problems that the screening efficiency is reduced along with the change of time due to the fact that the sieve holes of an existing mineral screening device are easy to wear and blocked, the screening device generates secondary pollution and screening result cannot be digitized.

Description

technical field [0001] The invention relates to a screening mechanism, in particular to a mineral particle size screening mechanism. Background technique [0002] Screening is an essential process in a block making plant. Whether it is sintering, pelletizing or pressing, there are certain requirements for the particle size of various raw materials. In the whole process of agglomeration, it is also necessary to sieve various samples. For example: the separation of sintering bottom material, the screening of returned ore, and the sintering of sintered ore, etc., all of which are completed through screening operations. Therefore, the screening operation is to ensure the smooth progress of agglomeration, and it is also the main component to obtain high-quality and high-yield agglomerate products and improve the production technical and economic indicators. [0003] The general sinter particle size screening device is roughly divided into two types: inertial vibrating screen (...
