Sludge dryer successfully exceeds design specifications

    The largest tannery sludge drying system built by Shenyang Yitong Venture Drying Co., Ltd. has been running smoothly in Wenzhou City, Zhejiang Province, exceeding the design criteria. The project is one of the top ten key environmental protection projects of the country.
    The sludge drying system uses a dedicated sludge dryer--single-pass rotary dryer as the drying host. It takes advantage of the single-channel dryer in handling the viscous material and adopts a series of sludge drying treatments. Technology, such as high-temperature rapid combined drying process, a new sludge incineration hot blast stove for burning sludge coal and drying sludge, a dedicated dehumidifier for exhaust gas, purification of hot air circulation technology, etc., establishes the largest tanning sludge drying project in China, and solves A series of problems in the drying of sludge in the sludge treatment project at the Shuitou Tanning Base.
    The dried sludge can be made into sludge coal, or directly burned at high temperature, which can reduce the volume of the sludge to the minimum, carbonize all the organic matters in the sludge, kill various pathogens, and reduce the pollution to the environment. It eventually becomes ash, which is used for the dehumidification and reuse of tail gas and the use of sludge coal technology, which reduces the energy consumption of sludge treatment and reduces the cost of sludge treatment.

    Zinc Die Casting Valve Parts are a metal forming process in which molten zinc metal is put under pressure and injected into a die. 


    Zinc are alloys that have high strength and hardness, outstanding corrosion resistance,full recyclability, mechanical properties, high thermal and electrical conductivity and strength at high temperatures. Zinc alloys possess high dimensional stability for complex shapes and excellent thin walls. The cost of raw material is low.

    Zinc Die Casting Valve Parts are efficient and economical and offers a wide range of durable shapes and components. Little or no machining is required after a part is die casted, because the process provides very close tolerances for even complex shapes. Zinc Die Castings can also be easily plated or finished. Zinc Die Casting Valve Parts are dimensionally stable and heat resistant.
    We have professionally produced Zinc Die Casting Valve Parts nearly 7 years. The parts have a great property of high quality, high precision, reasonable competetive price. our products are very popular.
