Cooperative Game among the Project Responsibility Person under the Supply Chain Environmen;

Project of drying system transforming oilburning into coalburningof Guizhou Wengfu 2×600 kt/a DAP plant;

The article indicates the existing problems of the drying system for 1# aluminum hydroxide,puts forward the improvement methods for eliminating the hidden dangers of the important equipments and the processes,which increase productivity capacity of the drying system and reduce the energy consumption.

In order to increase heat efficiency and improve environment,Lubi Company reconstructed the slag drying system,substituting high temperature smoke energy saving turbulen layer roaster for the combustion chamber of single layer coal rotary furnace and improving the inner materials spreading devices of the drier.

On the basis of the experimental results, the methods are introduced for calculating the drying coefficient K, and the different drying coefficients obtained from part of the experimental conditions are given.
