In the actual production, the dried materials include blocks, strips, granules, pastes, solutions and slurries. The original state of the materials determines the type of drying equipment selected. Therefore, we have to select suitable equipment according to the original state of the dry material. In addition, the feeding and discharging of drying equipment also have technical problems, and many aspects still rely on practical experience. From the economic point of view, the size of the processing volume is also a factor to consider when selecting drying equipment types.
The original state of liquid, mud and paste should be selected conductive heat transfer equipment, high thermal efficiency, solvent recovery. Liquid and slurry materials should be selected for spray drying and fluidized bed multi-stage drying in continuous batch processing; drum type, vacuum belt drying and inert fluid fluidized bed drying should be selected for small batch processing. The paste materials should be selected from air drying, stirred rotary drying, ventilated belt drying, and shock wave spray drying in continuous batch processing. In the case of small batch processing, conductive heating cylinder stirring or tank stirring drying, and vented box drying should be selected.
Convection-conducting heat transfer equipment should be selected for flake, granular, and powdery materials. The drying rate is high and the equipment investment is low, but the thermal efficiency is low. Sheet-type materials in large batches of continuous processing should be used when the belt ventilation drying and rotary ventilation and drying; in the small batch processing should use box type ventilation drying and vacuum cylinder mixing drying. The granular materials in the large batch of continuous processing should use the belt drying, rotary drying and fluidized bed drying; in the small batch processing should be used fluidized bed drying, tank stirring drying, box type ventilation drying and conical rotary dryer . The powdered materials should be selected from fluidized bed drying and air flow drying in continuous batch processing. In small batch processing, intermittent fluidized bed drying and vacuum cylindrical stirring drying should be used.
Drying of styling materials should be selected from continuous flow tunnel dryers and flat flow trolley dryers in large batches of continuous processing. Box dryers should be used for small batch processing.
For the drying of coatings and coating fluids, infrared dryers and spray fluidized bed dryers should be used in large batches of continuous processing; multiple drum dryers should be used in small batch processing.
Economical Advertising Plasma Cutting Machine
1. Imported guide rail, double four ball slider, heavy loading capability, smooth operation, high precision, long life.
2. High-speed stepper motor and driver, Y-axis using a dual-motor drive, to make high-speed operation up to 20 meters above the blank line speed, with the high power spindle can greatly enhance the carving speed more .
