Rotating braising dryer is liaoning dongda powder engineering technology Co., LTD, independent research and development of a special will paste, filter cake shape material continuous directly dry powder product become the new energy-saving equipment. An alternative to traditional pulse gas flow dryer for ordinary powder and granular materials of dry, dry intensity big, the equipment is small, highly low, on the materials have strong secondary crushing effect, can get more fine powder products.
Workflow:
From former procedure of wet material was sent to add feeder mixing manger, filter cake shape wet material be slowly rotating blender stir and pushed into a spiral feeder. Spiral feeder adopts stepless speed, will wet material quantitative into dry room for drying. The dry room at the bottom of the crushing institutions with certain RPM rapidly rotating, fresh air after heated by heater, with tangent state into dry room, in dry indoor form strong rotating airflow. Wet materials in crushing institutions and strong rotating joint under the action of airflow by grinding rapidly and dry granular materials, powder by air carry to dry room top, not dry thoroughly larger particles were drying chamber top graded ring classification to settlement after drying chamber bottom, with new join wet material together form a balanced fluidized bed. Fine powder product from dry room top continuous eduction, by the rear bag filter capture down, after unloading feeder eduction.
Structural features:
The bottom of the second-ranking drying chamber using pour tapered structure, hot air from the lower cloth wind chamber after the bottom of the loop gap high-speed tangential into dry room, the closer ring gap, average air tower speed is taller, provide a stable fluidized bed layer structure, and the material not easily fall into cloth wind chamber.
Second-ranking mixing finned using assembly type standard blade structure, easy to remove, interchange.
Second-ranking bottom into wind ring gap setting air cooling structure, can avoid completely material and heat surface contact, suitable for heat-sensitive materials dry.
Second-ranking in high-speed tangential hot air and mixing blades of high-speed rotating function, the material being constantly broken update the new dry surface, and with hot air maintained between high relative speed, dry strength is very high.
Machine adopts by vertical mixing manger and spiral feeder (single or double helix) composed of spiral feeder, can add combined-type paste or filter cake shape of discontinuous flow wet material converts in a certain rate under continuous logistics automatic joining dry room, do not need artificial homework.
Second-ranking for fluid shape wet material, must use the mud pump feeding, for a certain liquidity creamy materials and liquidity better powder and granular materials, can use simple double helix or single spiral feeder.
Compared with the traditional way to dry:
Second-ranking one-off dry into powder, do not need to secondary crushing.
Second-ranking continual drying, save Labour.
Second-ranking drying speed, suitable for heat-sensitive materials dry.
Second-ranking system, operating environment all airtight.
Compared with the spray drying:
Machine without the need for raw material for dilution or beating.
Second-ranking equipment is small, installation does not need a large space.
Machine maintenance and simple.
