FIELD: machine engineering.

SUBSTANCE: semi-automatic rotary drier comprises a loading conveyor, stands, a frame, a rotor, a heating chamber, heat generators, heat exchangers, external cylinders and internal cylinders. A loading conveyor is installed on a platform. Two upper platforms and two lower platforms are mounted on stands. An unloading conveyor is connected to the stands. The unloading conveyor is also mounted on the stands. A trolley with a trolley drive is mounted on a frame. An upper hopper is mounted on the trolley. A rotor is mounted inside the frame on rollers. A rotor fastener is used to secure the rotor in the required position. A heating fan and a cooling fan are connected to the frame from the front. The heating chamber is connected to the frame at the bottom. There are three heat generators connected to the heating chamber from the front. Two exhaust fans are connected to the heating chamber from the back. Exhaust fans communicate with heat exchangers. Six perforated outer cylinders are mounted in rotor brackets. The outer cylinders are closed with covers of the outer cylinders. There is a perforated inner cylinder with a cone for drier control installed inside each external cylinder by means of beams of the inner cylinder.

EFFECT: use of the dryer will allow to dry various materials during the year without substantial readjustment at high throughput.
