In order to improve the quality of urea products and enhance the market competitiveness of the products, Guizhou Meifeng has carefully studied and found out the reasons for the difficulties in controlling the quality of products, combined with the problems in the process, equipment, and management, and solved each one by one by one. .
By changing the pipe at the top of the granulating tower, the effective distance of the urea melt pump to the granulation nozzle can be shortened to the minimum, thereby shortening the time for generating the urea condensate. In view of the problem of grain size of urea products, an additional vibrating screen was added after the collection belt at the bottom of the granulation tower came out. An underground pool was built before the packing position. The powders from the two vibrating screens were dissolved and discharged into the underground pool to send urine. The tank is returned to the system for reprocessing, and powder urea and small urea are completely blocked outside the gate of the finished product warehouse.
Through a series of improvements, since the output of urea on July 10, except for the first class, which had a large number of defective products due to the original driving and external conditions, until July 14th, a total of 1446 tons of urea was produced. Among them, the qualified product rate reached more than 96%, making the urea system's product quality significantly better than before.
