Magnetizing and lubricating high-grinding coverage ceramic grinding ball and manufacturing method thereof

Abstract

The invention discloses a magnetizing and lubricating high-grinding coverage ceramic grinding ball and a manufacturing method thereof. The ceramic grinding ball is composed of three functional components, wherein the first functional component A is a ceramic matrix prepared by performing low-temperature sintering on a nano alumina powder, a silicon carbide powder, a molybdenum disulfide powder, alanthanum oxide powder, a zirconium dioxide powder, a calcium oxide powder and a silica powder serving as raw materials; the second functional component B is a magnetizing and lubricating surface layer prepared by performing high-temperature melting and curing on ferroferric oxide, molybdenum disulfide, silver, copper and titanium serving as raw materials; the third functional component C is a PVC(Polyvinyl Chloride) plastic material; the composition relation of the three components is as follows: the component C is firmly and completely mixed with the component A in a gridded manner so as toform a core, and the component B is a modified film layer sprayed and cured on the surface of the core by virtue of a high velocity oxygen flame spray process in argon shield. The ceramic grinding ball disclosed by the invention is high in surface lubricating and grinding efficiency, excellent in binding force, small in wear, low in energy consumption and uniform to grind.

Description

technical field [0001] The invention relates to the application field of ceramic materials, in particular to a magnetically lubricated high-grinding covered ceramic grinding ball and a manufacturing method thereof. Background technique [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.

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. At present, there are inevitably two problems in the equipment using ceramic ball grinding technology. : 1. Due to the low weight of ceramic balls, the extrusion force is insufficient at the same stirring rate, which leads to low ball milling efficiency, that is, the output efficiency of a single ball mill is low; 2. Because ceramic balls in the prior art are mostly used, the structure It is neither dense nor balanced, and at the same time, it is brittle and easy to break, so the loss in the ball milling process is faster than that of the original steel balls

[0003] Among the relevant patents that have been applied in China, the patent "A High-Efficiency Ball Mill with Magnetic Grinding Balls" (application number: 201410816874.4, publication date: 2016-7-20) discloses a double-layer grinding machine using magnetic steel balls. Grinding technology, but because the steel balls are used, the hardness is low and the quality is heavy, so the abrasive loss and power loss are high and the grinding effect is poor. At the same time, the magnetized grinding balls do not have high self-bonding force and surface lubrication.
