Fly ash particle size and particle morphology determine its application performance, according to the physical and chemical properties of fly ash and the fineness of the finished product to select the appropriate fine grinding equipment, is to determine the economic value of grinding fine ash and processing costs an important part. Ultra-fine pulverized coal ash powder is high quality and high efficiency of the two basic means.
Fly ash is an industrial waste discharged from coal-fired power plants. Speaking from the phase, fly ash is a mixture of crystalline and non-crystalline minerals. From the particle morphology, the fly ash is usually divided into beads and slag particles two categories. For grinding, the traditional process is to produce fly ash cement by pulverizing fly ash or a mixture of coarse ash and cement clinker. This mixed grinding process due to the light weight of the fly ash, small particle size, the lining will form within the mill hinder the grinding body clinker impact and grinding capacity, the two parts of the powder will not be fully ground when the wind power Belt out of the mill, resulting in the activity of fly ash and cement quality have an impact.
In order to achieve high quality and high efficiency of fly ash, in line with the requirements of economic development of energy saving and environmental protection, ultrafine pulverizer developed by Shanghai SBM has become the key equipment of fly ash grinding technology. It can be said that its excellent performance directly Affect and improve the processing effect of fly ash and finished product quality. SCM series ultrafine grinding is the crystallization of Sweden's advanced technology and years of experience of our company. It can process non-flammable and brittle materials with Moh's hardness 9, such as coal, mica, talc, graphite, quartz Stone, fluorite, calcite, limestone, dolomite, kaolin, bentonite, barite, potassium feldspar, coke, coal gangue, etc., are widely used in paint, paper, rubber, cosmetics and other industries.
The great advantage of the ultra-fine grinding of the state-state fly ash is that the grain size of the finished product is between 325-2500 meshes and the production capacity can be as high as 12 tons per hour. And because of its wear parts are made of special materials forged, stable performance equipment, low operating costs. In addition, the state strictly abide by the requirements of home green economy, the use of pulse dust collector and muffler in the ultrafine mill, truly environmentally friendly non-polluting operations.
Graphite is two kinds of mineral resources, is two kinds of crystalline carbon, iron color to dark gray, hardness 1.5, soft, creamy, belong to the conductor. Chemically inert, corrosion-resistant and acid, alkali reaction is not easy, because of its excellent performance is often used as anti-friction agents and lubricants, making crucibles, batteries, batteries, pencil lead.
In the second is the relatively large natural graphite products exports, but mostly exported graphite raw ore, deep drawing in the field of graphite is not covered. Non-renewable natural graphite resources continue to be lost in the export of primary products, while domestic enterprises need graphite import products at a price that is more than a hundredfold higher than the price of exported graphite. This is the status of my graphite development.
