Since the landfill management in place, easy to produce secondary pollution, together with the national development of relevant standards and technology policies sanitary landfill, the landfill for printing Sludge moisture content less than 60% provision, transverse shear is greater than 25KN / square meters. In fact, the dewatered cake moisture content greater than 80%, the use of direct landfill approach has been limited by current legislation does not allow direct landfill, countries in this regard have been stepped up enforcement. Heat drying sludge thermal drying sludge is mechanically dewatered sludge treatment and utilization of a Key Technology. Before discussing the various special drying sludge drying technology printing equipment, we first briefly analyze the changes in the process of sludge drying sludge properties. German engineer Karl belting analysis of sludge in the water distribution: water sludge clearance special drying equipment, external water sludge in the water between the clumps adhering water, adsorbed water gap siphon water petrochemical sludge special drying equipment, siphon water, capillary siphon water inside the water, extracellular fluid (hydration water, internal siphon water). Most of the interstitial water outside water can be separated by mechanical dewatering out, most of the internal water can only be separated by drying. Changzhou City Drying Equipment Co., a new main production: drying, granulation, mixing, grinding, dust, and other products, niche products: sludge dryer, flash dryer, vibration fluidized bed dryer, spray dryer, belt dryer, air dryer, a vacuum dryer, paddle dryer, tray dryer and the like. Special sludge drying equipment, a new drying (certified), special sludge drying equipment from Changzhou City, a new drying equipment co. Changzhou City, a new Drying Equipment Co.
