2. Guangxi Guiguang, Longguang Talc Industry Company The mining areas of the two companies are located in Longsheng County of Guangxi Province. The mine was built in 1970 and is an important production and export base for the Chinese talc industry. The annual production capacity of Guiguang and Longguang Company is 200,000 tons.
The talc reserves in this mine are rich in quality and are of first-class and second-class products, belonging to the carbonate type. The ore contains more than 70% talc, the associated mineral is chlorite, and contains a small amount of calcite . After the ore is sprayed with water, it is divided into two grades of +300mm and -300mm by a diagonal grid. +300mm grain level directly to the picking station to pick out the first grade, second grade talc and waste rock; -300mm grain grade through the vibrating screen to screen off -10mm tailings, +10mm grain level on the hand selection station to select one or two Grade talc and waste stone and talc rejects. In addition to talc, the plant uses two 4R and 5R Raymond mills to produce talc, paper talcum powder, medicinal talc and linoleum for linoleum. Manually sorting talc block 99kt/a, original ore size 600~0mm, original ore grade 70%, concentrate yield 93.75%, tailings 0~10mm talc content 5%, water consumption 2t/t ore. The annual output of talcum powder is 55,000 tons, of which the supply of pharmaceutical talcum powder accounts for 70% of the country. In recent years, Guiguang talc company has newly added a new talc ultrafine powder production line (two new products from Longguang Company) to produce three ultrafine powder products of 1,250 mesh, 2,500 mesh and 7 000 mesh (the process flow chart is shown in the figure). 4). The feed size is 325 mesh talc powder, and the main equipment is FJM680 jet mill and WTC315 turbine classifier. The air consumption is 40M 3 /min. The product fineness is 1 250 mesh (d98 is less than or equal to 10 μm), 2500 mesh (d90 is less than or equal to 5 μm), 7000 mesh (d90 is less than or equal to 2 μm), and the production capacity at the time of the table is 545 kg/h, 240 kg/h, respectively. 140kg/h.
(3) Main types and uses of deep-processed products 1. Talc powder
(1) Paper Patent â… , â…¡, â…¢ grade talc extra fine kaolin talc, calcium carbonate, titanium dioxide and other pigments with a control ink, gloss, brightness and opacity of the paper.
(2) Cable I and II talcum powder is used as filler for cables, rubber and plastics to improve the acid and alkali resistance, heat resistance, impact strength, thermal conductivity, tensile strength and creep resistance of plastics and rubber. Electrical insulation properties and improved rubber processing properties.
(3) a ceramic grade â… , â…¡ talc for ceramic ingredients can effectively control the thermal expansion of the ceramic body, as a glaze to provide an inexpensive source of magnesium oxide.
(4) Textile special grade I and II talc Powder Uses low wear and high whiteness of talc as a filling and whitening agent for textiles.
(5) Coatings I and II talc Powder The talc powder is easily dispersed in water and organic matter, and has high chemical inertness and high oil absorption, which can improve the dispersion of the coating.
(6) Pharmaceutical I, II grade talc powder can be used as a filler for cosmetics and as a carrier and additive for medicines and foods.
2. Talc carving products
Engraving arts and crafts with industrial grade I talc blocks or making industrial stone pens.
So what is laser engraving? The term [laser" is an acronym for Light Amplification by Stimulated Emission of Radiation. Basically a beam of light is reflected through a series of mirrors, that points the beam downward through a focus lens which is designed to concentrate the light into heat at an exact point. That point where the laser touches the surface is called the [focal point" and is where the heat is most intense. This focal point is less than a millimeter in size, however the diffraction of heat upon contact with the surface usually equates to roughly 1/200" in actual cutting accuracy. We produce cnc router machines for many years. How does laser engraving drifter from traditional printing? When you print something traditionally you add ink to paper. This is the opposite. We use the laser to remove material and what is normally [printed" will be cut away from your card with visible depth and texture. By varying the intensity of the beam, we can engrave at different depths, or even cut all the way through the material for a unique edge or die cut look. Another great thing about this process is that it does not involve any bits, blades, ink, or other components that need to be replaced, which allows us to ensure that each and every card is consistent in it`s look and end quality. We also offer full color UV printing which can also be done with laser engraving for a unique pairing.
