Ceramic grinding head material for grinder

Abstract

The invention relates to a ceramic grinding head material for a grinder. The ceramic grinding head material for the grinder comprises an outer grinding head material and an inner grinding head material, wherein the outer grinding head material consists of the following components in percentage by weight: 80 to 90 percent of aluminum oxide with purity being more than or equal to 99 percent, 5 to 15 percent of magnesium oxide and 3 to 10 percent of silicon oxide; the inner grinding head material consists of the following components in percentage by weight: 25 to 45 percent of aluminum oxide with purity being more than or equal to 99 percent, 45 to 55 percent of zirconium oxide with purity being more than or equal to 94 percent, 5 to 15 percent of magnesium oxide and 3 to 10 percent of silicon oxide. According to the ceramic grinding head material for the grinder, the defects of an existing ceramic material can be overcome, and the outer grinding head material and the inner grinding head material are made of ceramic.

Description

technical field [0001] The invention belongs to the field of kitchen utensils and ceramic materials, and specifically refers to a ceramic grinding head material for producing kitchen grinders. Background technique [0002] There are basically three ways to crush granular condiments: one is to grind the condiments in traditional ways such as crushing; the other is to grind a large amount of condiments and take them at any time; grind. Among these three methods, the traditional grinding method is time-consuming and laborious, and the mashing equipment is relatively large and inconvenient to use. The method of crushing a large amount of condiments and taking them at any time is relatively simple in use, but the disadvantage of this method is that when the condiments are crushed, the protection system of the original condiments is destroyed, resulting in accelerated oxidation reaction and easy Reduce or lose the efficacy of condiments. In order to change the shortcoming of ab...

AI Technical Summary

Problems solved by technology

[0004] The materials used to make the grinding head of the grinder are metal or high-strength plastic, and there are also technical considerations to use stone, but the strength of stone is not high and it is easy to crack and cannot be really put into use

The strength of the metal grinding head is acceptable, but the chemical corrosion resistance is poor, and if it is not used for a period of time, it will rust

High-strength plastic can also be used as a grinding head, but its wear resistance is poor. After a period of use, the gap between the grinding heads increases, making the frequency of replacing the grinding head higher

[0005] In response to this problem, the existing technology proposes to use ceramics as the grinding head material, but because of the poor ductility of ceramics, the assembly must be completed in the mold process or after the initial firing, and it must be ensured in the final assembly process. After the sintering is completed, it can maintain relative rotation and ensure that the gap is not large. It is too difficult to manufacture and the cost is high, so it is difficult to be popularized.
