Problems solved by technology

However, the currently used microcrystalline ceramic grinding bodies have three major problems: fragility, poor wear resistance, and inconsistent internal and external wear, and cannot be directly used in cement mills
In addition, the density of the ceramic grinding body is small, the tightness of the grinding body is lower than that of the metal grinding body, and the production capacity of the mill is reduced; when the performance of the material

Embodiment 1

[0053] An eco-friendly composite concrete grinding body for grinding, the composition of which is shown in Table 1.

[0054] Among them, the C3A content of cement is 5wt%, and the high activity component has a specific surface area of ​​400m 2 / kg, silicon powder with a purity of 60wt%, the toughening fiber is calcium carbonate whisker with a steel fiber diameter of 0.6mm and a length of 60mm, the alloy powder is 200 mesh aluminum-zinc alloy powder, the expansion agent is UEA expansion agent, and the water reducing agent is polycarbonate Carboxylic acid superplasticizer.

[0055] The preparation method of this grinding body is as follows: figure 1 As shown, the steps are as follows:

[0056] (1) batching each component according to the mass parts, adding 46 parts of water and pressing to obtain a wet billet;

[0057] (2) curing the wet billet obtained in step (1) at normal temperature to ensure the initial hydration time of the solid material;

[0058] (3) Form removal, st...

Abstract

The invention relates to an eco-friendly composite concrete grinding body for grinding and a preparation method thereof. The grinding body comprises 100 parts of cement; 197-213 parts of quartz sand;180-210 parts of high active components; 185-205 parts of toughening fibers; 25-35 parts of alloy powder; the high active components include any one of silicon powder, construction waste reclaimed powder, zeolite powder, ferrite powder, nano graphene oxide and ceramic waste powder, or combination of at least two kinds of the above components; the toughening fibers include any one of steel fiber, silicon carbide fiber, calcium carbonate whisker, basalt fiber and boron nitride fiber or combination of at least two kinds of the above fibers; the alloy powder includes aluminum zinc alloy powder and/or aluminum titanium alloy powder. The grinding body integrates high strength, high toughness, high hardness, high durability, low cost, and ecological and environmental protection as a whole, and the grinding body has universality and is applicable to design and development of various wear-resistant composite products.

Description

technical field [0001] The invention relates to the technical field of application of high-performance composite concrete, in particular to an ecological environment-friendly composite concrete grinding body for grinding and a preparation method thereof. Background technique [0002] With the development of science and technology, higher requirements are put forward for the separation and processing technology, especially the performance index of the grinding body, which requires that the powder particle shape of the grinding body is suitable, the particle size is smaller, and the gradation is reasonable; while the grinding lower energy consumption. [0003] The task of the grinding body is to crush the bulk material fed into the mill and grind it into fine powder. At present, the base materials of grinding bodies are mostly steel, iron and other metals or microcrystalline ceramics, but metal grinding bodies have defects such as large resource consumption, serious environme...
