Magnetized high combination power high grinding uniform ceramic grinding section and manufacturing method thereof

Abstract

The invention discloses a magnetized high combination power high grinding uniform ceramic grinding section and a manufacturing method thereof. The ceramic grinding section is prepared from three functional ingredients, wherein the first functional ingredient A is a ceramic substrate prepared from low-temperature sintering of raw materials of nanometer aluminum oxide powder, silicon carbide powder,molybdenum disulfide powder, yttrium oxide powder, zirconium dioxide powder, titanium dioxide powder and silicon dioxide powder; the second functional ingredient B is a magnetized lubrication surfacelayer obtained through high-temperature melting curing by using raw materials of ferroferric oxide, molybdenum disulfide, silver, copper and titanium; the third functional ingredient C is a PVA plastic material; the three ingredients have the composition relationship that the grid-shaped ingredient C is firmly and completely mixed with the ingredient A to be combined into an inner core; the ingredient B is a modified film layer sprayed and cured onto the surface of the inner core through high velocity oxy-fuel under the argon gas protection. The ceramic grinding section provided by the invention has the advantages that the surface layer is lubricated; the grinding efficiency is high; the combination power is high; the abrasion is small; the energy consumption is low; the grinding is moreuniform.

Description

technical field [0001] The invention relates to the technical field of cement grinding, in particular to a ceramic grinding section with high magnetization binding force, high grinding uniformity and a manufacturing method thereof. Background technique [0002] In the existing technology, with the rise of cement prices, the value of the industry in this field has risen rapidly, and with the development of technology, traditional steel grinding balls have been gradually replaced by ceramic grinding balls, but the current equipment using ceramic ball grinding technology is not available. There are two problems to avoid: 1, due to the low 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, due to the ceramic balls in the prior art Most of the grinding balls adopt rough sintering technology, the structure is neither dense nor balanced, but...

Problems solved by technology

[0002] In the existing technology, with the rise of cement prices, the value of the industry in this field has risen rapidly, and with the development of technology, traditional steel grinding balls have been gradually replaced by ceramic grinding balls, but the current equipment using ceramic ball grinding technology is not available. There are two problems to avoid: 1, due to the low 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, due to the ceramic balls in the prior art Most of the grinding balls adopt 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 grinding 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.
