Introduction to mineral powder dryer
Mineral powder dryer utilizes the high-temperature fast-drying process and successfully combines the characteristics of hot air slot vane dryer and pneumatic dryer. Materials are thrown and crushed under the action of high-speed rotating vanes, dispersed in the machine, and fully and effectively contacted with high-temperature hot air, thus realizing convective heat transfer, mass-heat transfer and continuous two-stage high-efficiency drying.
Characteristics of mineral powder dryer
(1) The mineral powder dryer utilizes the advanced high-temperature fast-drying process and has the advantages of large heat transfer coefficient and high thermal efficiency and drying intensity.
(2) The combination of high-speed stirring drying and pneumatic drying can fully scatter the sticky materials, greatly increase the contact area between the materials and heating medium and favorable for the drying.
(3) The mineral powder dryer is provided with a special scraping device which can avoid material adhesion on the wall.
(4) Wide application, simple operation, less maintenance and stable quality.
(5) The mineral powder dryer is specially designed for drying mineral powder, and it can adjust the angle of rotating vanes and the speed of rotating shaft.
(6) A wet material backflow layer is arranged on the mineral powder dryer, and the pneumatic dryer is provided with a special stirrer.
Composition of mineral powder dryer
The mineral powder dryer is mainly composed of the cylinder crushing dryer, combustion furnace, screw feeder, screw discharger, conveying pipeline, dust collector, air seal machinery, draft fan and control cabinet.
Composition and principle of mineral powder dryer
The complete set of equipment for mineral powder dryer is mainly composed of drum crushing dryer, combustion furnace, feeding screw, discharging screw, conveying pipeline, dust remover, air shut, induced draft fan, control cabinet, etc.
The ore powder is directly sent to the drum crushing dryer by the feeding screw, and is repeatedly picked up and scattered by the plate on the inner wall of the drum. After being broken up by the crushing device, the material is in full contact with the high-temperature medium with negative pressure to complete the heat and mass transfer process. Due to the inclination of the drum and the function of the induced and separated air, the materials move slowly from the feeding end, and then they are discharged by the discharging spiral after drying, and the tail gas is discharged into the atmosphere after being dedusted by the dust remover.
