Dedicated grinding aid capable of prolonging service life and improving uniformity of ceramic grinding ball and manufacturing method of grinding aid

Abstract

The invention discloses a dedicated grinding aid capable of prolonging life and improving uniformity of a ceramic grinding ball and a manufacturing method thereof. The dedicated grinding aid for the ceramic grinding ball is composed of three components, namely a component A, a component B and a component C, wherein the component A is 15-18 parts by weight of silica gel, the component B is sufficiently fermented produced acquired by taking 15-18 parts of corn starch as a raw material and 0.2-0.3 part of yeast powder as a microorganism; and the component C is a ceramic body solidified after performing high-temperature nitrogen atomization by taking 2-3 parts of active carbon powder and 8-10 parts of silicon dioxide as raw materials; the ceramic body comprises three ingredients, namely silicon dioxide, silicon nitride and active carbon; and the composition relation of the three components is that the component C is a core, the component A takes the component C as the center, and the component B is solidified surrounding the component A as a tackifier and an intermediate mass. The grinding aid disclosed by the invention has the technical effects of helping cutting, providing a buffer function, achieving a lubricating function and improving the cutting uniformity.

Problems solved by technology

[0002] Cement ball mill is a necessary process and key link in cement production. Its energy consumption and electricity consumption account for 30% of the total energy consumption of cement production and more than 70% of the total electricity consumption. At present, the national low-carbon environmental protection requirements are getting higher and higher. Although The price of cement is rising rapidly and the profit margin is increasing. However, in the existing technology, with the development of technology, the traditional steel grinding balls have been gradually replaced by ceramic grinding balls, and the current equipment using ceramic ball grinding technology inevitably has two Problems: 1. Due to the low self-weight of ceramic balls, the extrusion force is insufficient at the same stirring rate, resulting in low ball milling efficiency, that is, the output efficiency of a single ball mill is low; 2. Because most of the ceramic balls in the prior art use rough Sintering technology, the structure is neither dense nor balanced, but also brittle and easy to break, so the loss in the ball milling process is faster than that of the original steel ball

Especially after being combined with the first measure, due to the increase in the application of ceramic grinding bodies, the transformation of the mill structure, and the change of the material flow rate in the mill, the original cement grinding aids can no longer adapt to the impact of the new grinding body on the mill. a series of changes
