[0047] The present invention discloses a coal-saving agent production device and a process thereof, which comprises the following steps: firstly, a grinding motor 202 is started, and two worms 203 are rotated by the grinding motor 202, thereby two worm wheels 2010 are rotated, and then a coarse grinding roller 207 on the rear side and a fine grinding roller 208 on the rear side are rotated counterclockwise by the two worm wheels 2010, and then a coarse grinding roller 207 on the front side and a fine grinding roller 208 on the front side are rotated clockwise by driving a gear 209; then, a rare earth mineral raw material is put into a feeding port at the upper end of a grinding shell 201, and the rare earth mineral raw material falls to the gap between the two coarse grinding rollers 207 under the action of gravity, and the rare earth mineral raw material is ground by the two coarse grinding rollers 207 rotating in opposite directions, and then falls downward to the gap between the two fine grinding rollers 208, and is rotated by the two coarse grinding rollers 207 rotating in opposite directions. The ground rare earth mineral raw materials are further ground by the two rotating fine grinding rollers 208; the ground rare earth mineral raw materials fall into the screening box 402 for screening, and then the rare earth mineral raw materials with qualified volume are discharged through the discharge port of the guide box 401, and the rare earth mineral raw materials with unqualified volume are discharged through the discharge port of the screening box 402, and then the rare earth mineral raw materials with unqualified volume are put into the feeding port at the upper end of the grinding shell 201 again; then the rare earth mineral raw materials with qualified volume are put into the mixing equipment according to a certain proportion, and then a certain proportion of special emulsifiers, dispersants, sustained-release agents and penetrants and other raw materials are put into the mixing equipment, and mixed and stirred by the mixing equipment to obtain a coal-saving agent; the prepared coal-saving agent is packaged by the packaging equipment for easy storage and transportation.

[0048] The working principle of this embodiment is as follows: when in use, first start the grinding motor 202, and the grinding motor 202 drives the two worms 203 to rotate, thereby driving the two worm wheels 2010 to rotate, and then the two worm wheels 2010 drive a coarse grinding roller 207 on the rear side and a fine grinding roller 208 on the rear side to rotate counterclockwise, and then drive the gear 209 to drive a coarse grinding roller 207 on the front side and a fine grinding roller 208 on the front side to rotate clockwise; then the rare earth mineral raw material is put into the feeding port at the upper end of the grinding shell 201, and the rare earth mineral raw material falls into the gap between the two coarse grinding rollers 207 under the action of gravity, and rotates in opposite directions. The two coarse grinding rollers 207 rotate to grind the rare earth mineral raw material, and then the raw material falls downward to the gap between the two fine grinding rollers 208, and the ground rare earth mineral raw material is further ground by the two fine grinding rollers 208 rotating in opposite directions; the ground rare earth mineral raw material falls into the screening box 402 for screening, and then the rare earth mineral raw material with qualified volume is discharged through the discharge port of the guide box 401, and the rare earth mineral raw material with unqualified volume is discharged through the discharge port of the screening box 402, and then the unqualified rare earth mineral raw material with unqualified volume is put into the feeding port at the upper end of the grinding shell 201 again to continue the grinding process.

[0049] During the operation of the grinding motor 202, the first bevel gear, the second bevel gear, the transmission shaft 205, the first pulley 206, the second pulley 306 and the reciprocating screw 305 will rotate. At this time, the screw nut 304 drives the spreading bucket 301 to move back and forth left and right under the action of the spiral groove on the reciprocating screw 305, so that the rare earth mineral raw materials discharged from the discharge port at the lower end of the grinding shell 201 are evenly distributed inside the screening box 402, avoiding the rare earth mineral raw materials in the screening box 402 from piling up.

[0050] During the rotation of the reciprocating screw rod 305, the third pulley 307 drives the fourth pulley 504, the transmission rod 503, the fourth bevel gear, the third bevel gear, the rotating shaft 502 and the cam 5010 to rotate. When the protrusion of the cam 5010 faces upward, the protrusion of the cam 5010 pushes the moving frame 505 upward. At this time, the moving frame 505 moves away from the collision plate 403 with the knocking hammer 506, and the external spring of the guide column 508 will be in a compressed state. Then, when the protrusion of the cam 5010 faces downward, the moving frame 505 loses its upward pushing effect. At this time, the sliding block 507 moves downward rapidly with the moving frame 505 and the knocking hammer 506 under the action of the external spring force of the guide column 508, so that the knocking hammer 506 knocks on the upper end surface of the collision plate 403, thereby causing the collision plate 403, the material guide box 401 and the screening box 402 to vibrate, so that the blockage in the sieve hole of the screening box 402 is automatically cleared.
