Dehydration and drying of copper sulfate crystals in the electrolytic copper industry

Project Background:
A non-ferrous metal smelting company's electrolytic copper workshop crystallizes copper sulfate products from its waste liquid recovery system.. It is necessary to effectively separate the mother liquor of copper sulfate crystals and obtain a finished product with low water content, high purity, and intact particles to meet the sales standards of commercial grade.

II. Challenges and Needs:

Crystal protection: Gentle dehydration is required to avoid damaging the beautiful block shaped crystals, which may affect the product phase and value..

Low moisture content: The product requires strict moisture content (usually<3%), otherwise it is prone to clumping and affects sales.

Mother liquor recovery: Efficient separation of mother liquor is required to recover valuable metals from it..

Automation operation: Reduce labor intensity for workers and ensure consistent product quality..

III. Nuclear Xu Solution:
The core equipment is  DZYBelt press vacuum filter:

1.Pre dehydration and gentle pressing: First, most of the mother liquor is removed by vacuum filtration, and then a low-pressure wide filter belt is used for flexible pressing to further reduce moisture without crushing crystals..

2.Hot air drying system (optional): Add a hot air drying hood before unloading, and use low-temperature hot air to penetrate the filter cake, evaporating the surface moisture and ensuring that the moisture content is stable and meets the standard..

3.Intelligent control system: Automatically adjusts the filter belt speed and vacuum degree according to the feed concentration, achieving optimal dehydration effect and ensuring stable product quality..

4.Acid resistant construction: The parts in contact with the material are made of SS304 or 316 stainless steel to meet the requirements of the working conditions..

Fourth, Application Effect and Customer Value:

1.High quality product: The produced copper sulfate crystals are complete, brightly colored, and have a stable moisture content.; 2.5%  The following meets the standards for superior products.

2.Complete recovery: The mother liquor is clear with low solid content, effectively recovering copper resources from the solution..

3.Improving efficiency: High quality products have gained higher market prices and customer recognition, realizing the value-added of waste liquid..
