The second control motor then drives the feed cover 55 to close the feed opening and the aggregate is enclosed in the feed channel 45 between the feed cover 55 and the feed control gate 54. Then, the residual heat input pipe 56 inputs high-temperature hot gas into the closed space, and the high-temperature hot gas carries aggregate moisture and is output from the residual heat output pipe 57, so that the aggregate is dried in advance, and the final better drying effect of the aggregate is achieved. The drying efficiency of the follow-up aggregate is improved. The controller 30 can control the on-off of the waste heat electrically-controlled inlet valve 58 and the waste heat electrically-controlled outlet valve 59 to determine whether the high-temperature hot gas enters the closed space between the feeding cover 55 and the feeding control door 54 from the waste heat input pipe 56 and whether the aggregate moisture carried by the high-temperature hot gas is discharged from the closed space between the feeding cover 55 and the feeding control door 54 through the waste heat output pipe 57.

According to the structure, the controller 30 controls the exhaust electric control valve 61 to be opened, the induced draft fan 63 to operate, and high-temperature hot gas in the cylinder 1 is discharged after being dedusted by the bag-type dust remover 62.
The waste heat input pipe 56 is connected to an exhaust gas outlet pipe 60 between an exhaust gas electric control valve 61 and the feeding bin 19; the waste heat output pipe 57 is connected with a bag-type dust collector 62. According to the structure, when the aggregate needs to be pre-dried, the controller 30 controls the exhaust electric control valve 61 to be closed, the control waste heat electric control inlet valve 58 and the waste heat electric control outlet valve 59 are opened, the induced draft fan 63 is controlled to operate, high-temperature hot air in the barrel 1 enters the closed space between the feeding cover 55 and the feeding control door 54 through the waste heat input pipe 56, the high-temperature hot air pre-dries the aggregate, then the high-temperature hot air carries aggregate moisture to be discharged to the bag-type dust collector 62 from the closed space between the feeding cover 55 and the feeding control door 54 through the waste heat output pipe 57, and the bag-type dust collector 62 discharges the dust after removing. The high-temperature hot gas in the cylinder body 1 can be fully utilized, and the utilization rate of energy is improved. When the aggregate does not need to be pre-dried, the controller 30 controls the exhaust electric control valve 61 to be opened, controls the waste heat electric control inlet valve 58 and the waste heat electric control outlet valve 59 to be closed, controls the induced draft fan 63 to operate, and directly removes dust from the high-temperature hot gas in the cylinder 1 through the bag-type dust remover 62 and then discharges the dust.
