Ceramic grinding aid for ceramics grinding aluminate cement and manufacturing method thereof

Abstract

The invention discloses a ceramic grinding aid for ceramics grinding aluminate cement and a manufacturing method thereof. The ceramic grinding aid comprises three components, wherein a component A ispre-fermentation product obtained by mixing the following raw materials in parts by weight: 15-18 parts of wheat bran powder, 0.2-0.3 part of collagen activating enzyme water agent, 15-18 parts of drystraw powder and 0.2-0.3 part of Cytophaga agent and fermenting for 18-20 hours; a component B is soaking product by soaking the following raw materials in parts by weight: 150-180 parts of a sodiumsilicate aqueous solution containing sodium silicate solute with the concentration of 10%, 2-3 parts of pine bark and 2.2-2.4 parts of calcium oxide for 3 day; a component C is 8-10 parts of hard abrasive aid silica. The invention has modified magnesium cement to obtain the technical effects of acid-alkali resistance, good internal bonding force, anti-expansion, cushioning function, improvement incutting uniformity and cutting efficiency.

Description

technical field [0001] The invention relates to the technical field of ceramic grinding, in particular to a ceramic grinding aid for aluminate cement ceramic grinding and a manufacturing method thereof. Background technique [0002] Aluminate cement is a hydraulic cementitious material made of bauxite and limestone as raw materials, calcined clinker with calcium aluminate as the main component and an alumina content of about 50%, and then ground. Aluminate cement is often yellow or brown, but also gray. The main minerals of aluminate cement are monocalcium aluminate (CaO·Al2O3, abbreviated as CA) and other aluminates, as well as a small amount of dicalcium silicate (2CaO·SiO2), etc., and the colors are mostly gray and white. Aluminate cement sets and hardens quickly. The 1d strength can reach more than 80% of the highest strength, and it is mainly used for projects with urgent construction schedules, such as national defense, roads and special emergency repair projects.

Problems solved by technology

[0003] 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
