Detailed Description
The invention is further illustrated by way of example in the following with reference to the accompanying drawings.
Referring to the attached drawings 1-4, the high-efficiency dry grinding machine for waste steel slag comprises a roller 1, a feeding and discharging port 2, a motor 3, a bracket 7, a fan 8, a lifting plate 10 and a blanking hole 11, wherein two ends of the roller 1 are respectively and rotatably connected to the bracket 7, the motor 3 is in driving connection with one end of the roller 1 through a transmission mechanism, and the other end of the roller 1 is provided with the fan 8; the drum 1 is polygonal, a feeding and discharging port 2 is arranged on one edge surface of the polygonal drum, a cover plate is arranged on the feeding and discharging port 2, a plurality of blanking holes 11 are respectively arranged on other edge surfaces of the polygonal drum, and a material lifting plate 10 is arranged on each edge on the inner side of the polygonal drum.
In this example, referring to fig. 1 and 2, the transmission mechanism of the motor 3 comprises a belt pulley set 4 and a speed regulator 5, and the motor 3 is in driving connection with the roller 1 through the belt pulley set 4 and the speed regulator 5. Different rotating speeds of the roller 1 can be realized through the belt pulley group 4 and the speed regulator 5, and the rotating speed can be adjusted according to the condition of materials.
