How much is a ton of kaolin? Kaolin Craft Making Release time: 2020-05-26 16:12 Source: Master Wan Reading volume: 1653 Kaolin, whose main component is kaolinite or halloysite, is a very pure and delicate clay. It was named after being found in the nearby Gaoling Village. This encyclopedia mainly introduces kaolin around the introduction of kaolin, the process of making kaolin, the general price of kaolin, and the pictures of kaolin. Introduction to Kaolin It is a non-metallic mineral, clay and clay rock dominated by kaolinite clay minerals. It is named after Gaoling Village, Jingde Town, Jiangxi Province, China. The pure kaolin is white, fine, soft and soft, with good plasticity and fire resistance. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin has a wide range of uses. It is mainly used in papermaking, ceramics and refractory materials, followed by coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount is used in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soap, Pesticide, medicine, textile, petroleum, chemical, building materials, national defense and other industrial sectors. The process of making kaolin 1. The process flow of kaolin starts from crushing. At present, there are three main crushing methods. The first is mechanical crushing, and the fineness of crushing is about 300-1000 mesh. The second type of jet pulverization, the pulverization fineness range is about 5000 mesh, because the pulverized fine powder contains other mineral components and impurities. The third high-pressure extrusion method. Therefore, industries with different, purity requirements must use different crushing methods to ensure their purity.
classifiers, spiral classifiers, hydrocyclones and vibrating screens to remove kaolin powder, mainly for coarser texture. Mineral impurities and rock impurities. You can also use a screen to separate the larger particles. Because the size and density of the mineral particles are different, it facilitates the classification. After the large particles are separated, they can be separated by water dust, hydrocyclones, and centrifugals. Simple machines such as machines further separate the kaolin. Kaolin mostly contains iron minerals. If it is not removed, it may affect some production processes.If you want higher purity kaolin, these iron ore will be removed. Magneticseparation is an effective way to remove these impurities. The magneticdifference of minerals does not require the intervention of chemicals. 3. Kaolin has the characteristics of whiteness and brightness. If it is used to make pigments, fillers and coatings, then the whiteness and brightness of kaolin have high requirements, because its whiteness and brightness directly affect their value, so It needs to be bleached, the main methods are magnetic bleaching, chemical bleaching, flotation bleaching and so on. If it is to make porcelain raw materials, a series of processing such as calcination is required.
Looks like our LRS Kaolin ore with little bit high Fe2O3 ( 2.5% ) need a magnetic separation then may increase brightness ( sample shown 72% ).
