| | HG Specially Drier for Gingko | | Principle of work: | | After the damp raw material is put into the drier,the raw material will be distributed in the drier uniformly through uniform distributed stirring-up rake inside the drier and contact with countercurrent not air fully.It speeds up heat and mass transfer.During the period of dry,the raw material is affected by stirring-up rake with gradient and hot air,it can be moved and passed through th e dry region and reached to star valve and then discharge the finished product. | | Application: | 
is suitable for drying raw materials that have large size and heavy specific gravity.Forexample,ore,slag of blast furnace,coal,metalic powder,phosphorus fertilizer,ammonium sulfate.dry powder,granule raw materials which habe special requirements to drying .For example:Hpvesicang,less,lighe calcium carbonate,active white earth,magnetic powder,graphite,medical slag,etc.dry raw materials that magnetic powder,graphite,medical slag.etc.dry raw materials that need to dry at low temperature continuously and ist batch is large. | | Features: | The mechanization degree of revolving drier is high and its production capacity is large.
The resistance when fluid passes through the cylinder is small,the consumption of power is low.
Have strong adaptability to raw materials. | | Technical Parameters: | type | direct heating | direct heating clockwise | heat directly | heat directly | complex heat | complex heat | kinds of raw material | ore | vesicant | slag of blast fumace | slag of fumace | phosporus fertilizer | coal | amount be treatedKg/h | 1000 | 466 | 15000 | 20000 | 5000 | 1000 | primary moisture % | 30 | 13 | 6 | 1.5 | 6.5 | 30 | final moisture % | 15 | 0.3 | 1 | 0.1 | 0.1 | 15 | average diameter mm | 6.5 | 0.05 | 4.7 | 0.5-1.7 | 5 | 6.5 | bulk density Kg/m3 | 770 | 800 | 1890 | 1100 | 750 | 770 | amount of Kg/h | 39000 | 5400 | 10750 | 9800 | 16000 | 39000 | temperature ℃ | 600 | 165 | 500 | 180 | 570 | 600 | material outlet ℃ | | 42 | 100 | 70 | 75 | | way of heating | gas | steam of electric | heavy oil | coal fuel | heavy oil | heavy oil | loading efficiency % | | 6.3 | 7 | 7.5 | 18 | | revoluting r.pm | 4 | 4 | 3.5 | 3 | 2 | 4 | gradient m/m | 0.04 | 0.005 | 0.03 | 0.05 | 0.043 | 0.04 | quantity of stirring-up rake | 12 | 24 | 12 | 12 | outer of8
