  Among the factors that affect the drying effect of materials, the rotation speed of the rotary drum dryer has a very important role. What is the specific effect of the rotation speed of the rotary drum dryer? How to adjust the tumble dryer speed to the best?

  It is determined through experiments that the L-shaped lifting plate of each structural angle has an optimal rotation speed. At the optimal rotation speed, the material that is lifted occupies the largest area in the cross section of the barrel, and the heat exchange is the best. The optimal speed increases with the structural angle of the lifting plate. In actual production, the speed of the dryer should be determined according to the structural angle of the lifting plate. At the optimal speed, the area of the material lifted by the L-shaped lifting plate of various structural angles in the cross section of the barrel is different. The occupied area increases as the structural angle of the lifting plate decreases. In actual production, more lifting plates with a structural angle of 90 ° should be selected to improve the dispersion of the materials. Another important factor that affects the drying of materials is the speed of the dryer cylinder. Dryers with different structure sizes of lifting plates should use different speeds, but the actual speed of the dryer is fixed. If the speed is too fast, the barrel section material will shift to the left. If the speed is too slow, the barrel section material will shift to the right. Therefore, the speed is too fast and too slow to reduce the area occupied by the material in the simplified section. Only when the material is distributed in the middle of the section of the dryer barrel, the area of the material in the barrel section is the largest, and the heat exchange is the best. Therefore, the lifting plates with different structural angles should use different speeds, that is, they should have different optimal speeds.
