Embodiment Construction

[0016] A method for producing metallurgical auxiliary materials, comprising the following steps:

[0017] a) Material selection: The selected qualified raw materials are stored in the intermediate silo through lifting equipment to ensure the reliability of raw materials for production;

[0018] b) Broken material: the raw material selected in step a) enters the crusher through the feeding pipeline and then crushed, and the crushing time is 110-130 minutes;

[0019] c) first screening: the auxiliary material after step b) is broken through the first screening device to carry out the first screening process to ensure that the stone powder in the auxiliary material is sieved and discharged and stacked;

[0020] d) second sieving: the auxiliary material processed in step c) is subjected to the second sieving process through the second sieving device to ensure that the melon seeds in the auxiliary material are sieved and discharged and stacked;

[0021] e) The third screening: the...

Abstract

The invention provides a production method of metallurgical auxiliary materials. The method comprises the following steps: selection of materials, pulverizing of materials, first screening, second screening, third screening, and feeding back. The method is advantageous in that the production method which comprises selection of materials, pulverizing of materials, first screening, second screening, third screening, and feeding back is carried out for the materials in order for production, so that the method can effectively reduce defects of auxiliary material separation by means of crushing in the prior art, reduce mass of the auxiliary materials after the screening steps, prevent other auxiliary materials doping in the auxiliary materials, reduce working strength due to crushing by a crusher, reduce damage of the crusher, and improve production efficiency; compared with the production cost of crushing and screening by the crusher in the prior art, the production method is reduced by 30-40%, subsequent screening of the auxiliary material is reduced, working strength is low, and the usage effects are good.

Description

technical field [0001] The invention relates to a method for producing metallurgical auxiliary materials. Background technique [0002] In the existing production of auxiliary materials, due to the different crushing degrees of the crushers, the raw materials can be crushed into stone powder, melon seeds, stones, etc. of different sizes. The existing production methods all use crushers to crush the raw materials into large particles. Broken into melon seeds and subsequent stone powder, the workload of the crusher is large and easily damaged, and the production cost is high. Such a crushing effect is not conducive to sieving, and other auxiliary materials are easily mixed with other auxiliary materials, resulting in low production efficiency and low sieving effect. Defects such as high work intensity. Contents of the invention [0003] The technical problem to be solved by the present invention is that it is not easy to sieve the crushed auxiliary materials after the exist...
