KJG-70 Electroplating Sludge Four-Shaft Paddle Dryer

Electroplating is a heavily polluting industry, yet it is not one that people are compelled to use. Various precision parts undergo surface treatment and finishing through electroplating. The electroplating industry generates a large amount of sludge and wastewater that need to be treated; otherwise, it can lead to serious pollution issues. The wastewater from electroplating requires neutralization treatment with lime and other substances, but this creates another form of pollution, namely electroplating sludge. The danger of electroplating sludge lies in heavy metals and their leachates, primarily copper, nickel, chromium, cyanide, and zinc. According to current national environmental protection policies, all electroplating sludge should be uniformly collected by qualified enterprises. The treatment of electroplating sludge is a significant environmental protection cost for many electroplating companies. Using an electroplating sludge dryer to dry the sludge can greatly reduce the cost of recovery based on weight. Therefore, many companies now use electroplating sludge paddle dryers to dry and treat the sludge before submitting it for disposal, thereby reducing expenses.

The KJG-73 electroplating sludge paddle dryer has the following features:

Changzhou Lima Drying Engineering Co., Ltd. specializes in the design and production of electroplating sludge paddle dryers, targeting industries such as printing and dyeing, papermaking, biotechnology, electroplating, thermal power, chemical engineering, and wastewater treatment plants. Generally, the initial moisture content of sludge after dewatering is 80%, and the final moisture content after drying is 10% to 50%, with typical sludge requiring around 30%. The dried sludge forms loose, granular particles that can be mixed with coal powder and directly fed into boilers for combustion. The calorific value of sludge is approximately 1500-2000 kcal, enabling waste utilization and energy savings. Some dried sludge can also be processed into fertilizers or construction materials, or directly landfilled without causing secondary pollution, turning waste into valuable resources and fully meeting environmental protection requirements. This equipment features low energy consumption and can utilize heat sources such as steam, thermal oil, hot air, or flue gas for heating (evaporating 1 kg of water consumes 1.1 to 1.3 kg of steam). It offers advantages such as low power consumption, stable operation, low noise, minimal labor requirements, and is essentially fully automated in production.

As corporate environmental awareness continues to grow, sludge has become a common challenge hindering business development. Changzhou Lima Drying Engineering Co., Ltd. has introduced advanced foreign sludge drying technology and, based on domestic conditions, developed an electroplating sludge paddle dryer that fully meets the requirements of industry clients. This has earned the trust and cooperation of an increasing number of enterprises. Having collaborated with over fifty large, medium, and small enterprises in China, our company is committed to serving you with superior technology, working together to create a greener earth.
