After moving the sliding arm 15 to the required position in cooperation with the U-shaped limiting hole 14, rotate the first screw 13 clockwise to fix the sliding arm 15 and the vertical plate 16.

Put the recycled old asphalt concrete into the tank body 3 from the feeding hopper 6, turn on the heating mechanism 4 and the servo motor 9. Through the meshing of the driving gear 10 and the driven gear 11, drive the side frame 2 to rotate and dry.
