Heat energy (hot water, low-pressure steam or heat transfer oil) is introduced into the closed interlayer, and the heat is transferred to the dried material through the inner shell. Driven by power, the tank body rotates slowly, the materials in the tank are constantly turned and mixed, and the heat is received from the inner surface of the wall, so as to achieve the purpose of strengthening drying. The material is in a vacuum state, and the vapor pressure drops to make the water (solvent) on the surface of the material reach a saturated state and evaporate, and is discharged and recovered by a vacuum pump in time. The moisture (solvent) inside the material continuously penetrates, evaporates and discharges to the surface. The three processes are carried out continuously, and the material achieves the purpose of drying in a short time.

The Saudi Arabia Aden Phosphate Beneficiation Project is the world's largest phosphate ore beneficiation plant designed by the China Blue Horizon Design Institute for the first time using international standards. The engineering design part was basically completed in early 2009. After more than one year of intense construction, the single-machine test of the crushing and crushing areas of the plant has basically ended. Some areas have passed the acceptance of owners of international management companies Worleyparson and Saudi Aaton. The progress of the project is relatively smooth.
The 200,000-ton Potash Fertilizer Plant Project in Uzbekistan de Hakkarbad, designed by the China Blue Ocean Design Institute, uses Russian potash salt coarse-grained flotation technology. The process was digested, absorbed and reinvented by engineers and technicians. Combined with the advanced technology and mature experience in potash fertilizer processing accumulated by the hospital for many years, it completed the engineering design from process to practice and built a modern potash fertilizer processing plant. After 72 hours continuous performance evaluation of the production equipment, the product content of potassium chloride is more than 95%, and the yield is over 88%. The production capacity of the equipment fully meets the engineering design requirements and is highly valued by the Uzbek government.
Phosphorite companies work together to design a unit to go abroad
The 12.5 million tons of phosphate ore beneficiation device for the original ore in the Saudi Arabia Aden Phosphate beneficiation project, the largest single phosphate ore beneficiation plant in the world designed and contracted by Zhaofu (Group) Co., Ltd., undertaken by Zhongfulian (Group) Co., Ltd. Construction is now nearing completion. At the same time, the 200,000-ton/year potash plant in Dekhkarabad, Uzbekistan, which was designed and carried out by China Blue Horizon Design Institute, was completed and put into operation in late October. This is a feat that China's phosphate mining companies and design agencies have jointly created to go abroad.
