Standard anthracite Mad 1.5-2.5% Ad 2.5-4.0% Vdaf 6.5-8.0% Mad air dry basis dry basis moisture Ad ash Vdaf dry ash-based bond index test 1. volatile coal, should be to achieve the air-dried state particle size analysis of coal samples of less than 0.2mm, wherein the coal particles 0.1-0.2mm total of 10-35% coal, coal samples prior to testing, should be mixed. 2. The bond index test coal samples should be packed in a sealed container, after the test sample preparation time should not exceed one week as more than a week, should be in the report indicate the sample preparation and test time. 3. Determination of caking index anthracite used, must be 宁夏汝 Kei special anthracite coal mine. Special anthracite sampling, sample preparation according to national standards anthracite filter water treatment filter using artificial classification, can reduce irrelevant minerals and reduce the ash content. Water filter also be filtered and rinsed, to ensure their use for water filtration. Due to better solids holding capacity Jincheng Anthracite, so anthracite can reliably improve the ability to remove suspended particles. In addition, its low coefficient of uniformity, help speed up the flow rate. Refined anthracite filter using the Shanxi quality anthracite as raw material selection, crushing, screening, and twice made the appearance of shiny, spherical, high mechanical strength, good compression performance, chemical stability, non-toxic substances, wear resistance in acidic, neutral, alkaline water are not dissolved price anthracite, anthracite particles additionally surface roughness, good adsorption capacity how much the latest one ton of anthracite, porosity (> 50%), higher containing sewage capacity, due to light, the required backwash lower intensity, can save a lot of backwash water and electricity. Anthracite filter media used in conjunction with quartz sand is the promotion of China's current fast filter and three-layer filter, the best canister filter material. It is to improve the filtration rate per unit area increases exponentially increase the interception capacity of water and reduce the project cost and most effective way to reduce the footprint. Anthracite filter specifications diameter: 1, size range for anthracite filter drinking water is: 0.8-1.2mm, 1.2-2mm; YH-101 type industrial washing Anthracite size range is: 1 -2mm, 2-4mm, 4-6mm. 2, in various particle sizes in the range of anthracite media, particle size less than the specified lower limit should not exceed 3%, greater than the specified upper limit of the particle size should not exceed 2%. Anthracite Packaging and Storage: plastic woven bag, 50 kg. Store in a cool dry place, not exposure. North Branch Green Clean Environmental Protection Technology Co., Ltd. is a professional media production expertise, construction has been 26 years of history, it is now part of a permanent Environmental Protection Technology Co., Ltd., Henan. Market demand, I Division and the major institutions and research institutes to maintain close cooperation, committed to the development of new technologies and new materials in the field of environmental protection, to explore first-class production technology. The product has been used in electric power, petroleum, chemical, paper, printing and dyeing, metallurgy, iron and steel, food and beverage, water and municipal engineering and other industries user preference.
