Anthracite commonly known as "white coal", is the deepest coal rank coal. Is a water filtration materials industry. I produced the anthracite filter media (Executive standard: People's Republic of urban construction industry standards (CJ/T43-2005) is the choice of Jiaozuo, Henan, Shanxi Jincheng and two high-quality anthracite as raw material mining. After crushing, screening, washing and processing percent. is characterized by: fixed carbon content, density, strength, appearance, good gloss, chemical stability, good retention of solid particles, can reliably increase the removal of suspended particles. does not contain toxic and hazardous substances. In acidic, neutral, not dissolve in water. compression wear resistance, and have sufficient surface area and a reasonable size gradation. Because of better retention of solid particles, it can reliably improve the scavenging ability of suspended particles. for in drinking water and industrial water filtration. 
 Anthracite filter media of the technical requirements: 
 1, anthracite filter media fragmentation rate and the wear rate and should not exceed 3% (percentage by mass, the same below.) 
 2, anthracite filter media, the average density is generally not less than 1.4g/cm3, no more than 1.6g/cm3. 
 3, anthracite filter media should not contain visible dirt, shale, and foreign debris. Clay content should not exceed 3%, the material density greater than 1.8g/cm3 content should not exceed 8%. 
 4, anthracite filter media of the soluble rate should not exceed 3.5%. 
 Anthracite filter media particle size: 
 1 filter for drinking water in the anthracite particle size range :0.8-1 .2 mm ,1.2-2mm; industrial water filter particle size range of anthracite :1-2mm ,2-4mm ,4-6mm. 
 2, in a variety of anthracite filter media in the size range, less than the specified minimum size should not exceed 3%, greater than the specified maximum size should not exceed 2%.
