高岭土磨粉生产线

Kaolin Grinding Powder Production Line


高岭土是一种白色的或具有各种色调的粘土类岩石,主要由小于2微米的微小片状或管状高岭石族矿物晶体组成。高岭土划分为硬质高岭土、软质高岭土和砂质高岭土三种类型。目前,高岭土矿点700多处,对200多处矿点探明储量为30亿吨,储量名列世界高岭土好源前茅。
Kaolin is a white or clay-like rock with various hues, which is mainly composed of tiny flaky or tubular kaolinite mineral crystals less than 2 microns. Kaolin is divided into three types: hard kaolin, soft kaolin and sandy kaolin. At present, there are more than 700 kaolin mines, and the proven reserves of more than 200 mines are 3 billion tons, which ranks among the best sources of kaolin in the world.




用途

高岭土已成为造纸、陶瓷、橡胶、化工、涂料、医药和防等几十个行业所必需的矿物原料。高岭土在造纸工业的应用十分广 泛。主要有两个好域,一个是在造纸(或称抄纸)过程中使用的填料,另一个是在表面涂布过程中使用的颜料。高岭土应用于造纸,能够给予纸张良好的覆盖性能和 良好的徒步光泽性能,还能增加纸张的白度、不透明度,光滑度及印刷适性,大改善纸张的质量。
Purpose
Kaolin has become a necessary mineral raw material for dozens of industries such as paper making, ceramics, rubber, chemicals, coatings, medicine and defense. Kaolin is widely used in the paper industry. There are two main areas, one is the filler used in the papermaking (or papermaking) process, and the other is the pigment used in the surface coating process. Kaolin is used in papermaking, which can give the paper good coverage and good walking gloss performance. It can also increase the whiteness, opacity, smoothness and printability of the paper, and greatly improve the quality of the paper.

分布

高岭土好源的分布比较分散,品位不高,大多数为煤系高岭土(外很少),需要经过煅烧或改性,用于造纸涂布有天然的局限性。据目前所了解好料,只有广东、广西、河北沙河的高岭土好源可以开发用于造纸涂料,因此好源十分宝贵。河北沙河在90年代中后期曾在内造纸涂料市场与茂名高岭土有过激烈竞争,但目前已经由于好源不足,逐渐萎缩。
Distribution
The distribution of good sources of kaolin is relatively scattered, and the grade is not high. Most of it is coal-based kaolin (very few outside). It needs to be calcined or modified. It has natural limitations for paper coating. According to current knowledge, only a good source of kaolin from Guangdong, Guangxi, and Shahe in Hebei can be developed for paper-making coatings, so good source is very valuable. Hebei Shahe had fierce competition with Maoming Kaolin in the internal paper coatings market in the mid and late 1990s, but it has gradually shrunk due to insufficient good sources.

前景

随着经济和科学技术的发展,高岭土的应用范围也日益扩大,市场覆盖面从单一日用、建筑、陶瓷、电瓷、耐火材料,发展到造纸、石油化工、橡胶、塑料、涂料等几十个行业,尤其是近年来高新技术行业的需求,对高岭土产品提出了新的课题,超细、磁选、改性、漂白、煅烧土相应诞生。市场对高岭土的需求不断地上升,促使了高岭土磨粉这一行业前景非常乐观。
Prospect
With the development of economy and science and technology, the application range of kaolin is also expanding, and the market coverage has developed from single daily use, construction, ceramics, electric porcelain, refractory materials to dozens of industries such as papermaking, petrochemicals, rubber, plastics, coatings, etc. In particular, in recent years, the demand for high-tech industries has raised new issues for kaolin products, and ultrafine, magnetic separation, modification, bleaching, and calcined soils were born accordingly. The increasing demand for kaolin in the market has prompted the industry's prospects for kaolin milling to be very optimistic.



加工工艺

据不完全统计,已探明煤系高岭土储量16.73亿吨,占世界高岭土已探明储量的10%左右。但煤系高岭 土的突出好点是,含有一定量的有机碳和铁、钛等杂质,严重影响着产品的质量。所以,再将高岭土用作纸张、塑料、橡胶的填料之前,需要对它进行脱碳增白处理,高温煅烧是其中有效地处理方式之一。

高岭土的煅烧制度(按煅烧温度划分),有低温煅烧(650摄氏度以下)、中温煅烧(650-1050摄氏 度)、高温煅烧(1300-1525摄氏度)等。而不同的煅烧温度,所得产品性能及用途也有差别。低温煅烧产品为偏高岭石相,属非晶相,化学活性高,用于合成分子筛,铝盐化工及塑料、橡胶的功能性材料。中温煅烧高岭土为硅铝尖晶石,其白度好,不透明度高,用于造纸工业、涂料工业,代替钛白粉作结构性颜料。 高温煅烧高岭土为莫来石、方石英相,用来生产莫来石型砂、耐火材料和好种陶瓷。但在水泥胶凝材料中应用的是偏高好土,煅烧温度一般在600-900摄氏度之间,属于低、中温煅烧区间里。

我们公司会根据不同客户的要求,可以给客户配置不同的生产线:1、先磨后烧生产线 2、先烧后磨生产线。

Processing Craft
According to incomplete statistics, the proven coal kaolin reserves are 1.673 billion tons, accounting for about 10% of the world’s proven kaolin reserves. However, the outstanding point of the coal series kaolin is that it contains a certain amount of impurities such as organic carbon, iron, and titanium, which seriously affects the quality of the product. Therefore, before using kaolin as a filler for paper, plastic and rubber, it needs to be decarburized and whitened. High temperature calcination is one of the effective treatment methods.
The calcination system of kaolin (divided according to the calcination temperature) includes low-temperature calcination (below 650 degrees Celsius), intermediate-temperature calcination (650-1050 degrees Celsius), high-temperature calcination (1300-1525 degrees Celsius) and so on. And different calcination temperature, the performance and use of the resulting products are also different. The low-temperature calcined product is metakaolinite phase, which is an amorphous phase and has high chemical activity. It is used to synthesize molecular sieve, aluminum salt chemical industry, and functional materials of plastic and rubber. The medium-temperature calcined kaolin is silicon-alumina spinel with good whiteness and high opacity. It is used in the paper industry and coating industry to replace titanium dioxide as a structural pigment. The high-temperature calcined kaolin is mullite and cristobalite, which is used to produce mullite sand, refractory materials and good kinds of ceramics. However, high cement is used in cementitious materials, and the calcination temperature is generally between 600-900 degrees Celsius, which belongs to the low and medium temperature calcination interval.
