Project Name:

China Vacuum Belt Filter for Lop Nor Potash Fertilizer Project 

Equipment on Site:57 Sets of Belt Filter DU72-3200

Project Finished Time:2007


Project Introduction:

Lop Nor Potash Fertilizer Project is the largest Vacuum Belt Filter use site in the world.The project of 1.2 million tons/year potash fertilizer started construction in April 2006, and the commissioning test was successful on November 18,2008. The test data of the high-grade potassium sulfate product showed that the indexes of lop Nor potassium sulfate product reached or exceeded the national standard of first-class products, and the product did not contain free acid, so it is the rare high-quality chlorine-free potassium fertilizer in the world at present


The rubber belt vacuum filter is a high-efficiency filtration and solid-liquid separation equipment independently developed by our company on the basis of the introduction of foreign technology of similar products.


The DU rubber belt vacuum filter is equipment that realizes solid-liquid separation with vacuum negative pressure as driving force. In the structure, its filtration section is arranged along the horizontal length and it can continuously perform filtrating, washing, blotting, and filter cloth regeneration etc. The equipment has the advantages of high filtration efficiency, large production capacity, good washing effect, low water content of the filter cake, flexible operation and low maintenance cost etc. It can be widely used for solid-liquid separation in the fields of metallurgy, mining, chemical, papermaking, food, pharmacy and environmental protection etc. and it particularly has a good application in the flue gas desulfurization gypsum dehydration (FGD).
