and the driving shaft 38 of the low-speed driving motor 37 is rotated by the operation of the low-speed driving motor 37, the driving shaft 38 drives the driving bevel gear 40 to rotate, and the driving bevel gear 40 drives the large bevel gear 8 and the large bevel gear 22 to rotate by the meshing of the driving bevel gear 40 and the large bevel gear 8 and the large bevel gear 22, so that the upper grinding disc 3 and the lower grinding disc 21 start to rotate, and the upper grinding disc 3 and the lower grinding disc 21 are kept stationary during the rotation process by the sliding connection of the annular sliding support plate 4 and the concave sliding seat 5, and simultaneously, due to the position relationship of the large bevel gear 8 and the large bevel gear 22, when the driving bevel gear 40 rotates, the rotating directions of the large bevel gear 8 and the large bevel gear 22 are opposite, so that the rotating directions of the upper grinding disc 3 and the lower grinding disc 21 are opposite, so that the relative speed between the upper grinding disc 3 and the lower grinding disc 21 is increased, thereby improving the grinding efficiency of the cement base material;

and as the upper grinding disc 3 rotates, at this time, because the feeding funnel 32 is in a fixed state, the fixed bevel gear 35 on the feeding funnel 32 is kept stationary, and as the upper grinding disc 3 rotates, the upper grinding disc 3 drives the adjusting bevel gear 20 to start moving around the fixed bevel gear 35, and during the movement of the adjusting bevel gear 20, the adjusting bevel gear 20 starts to rotate through the engagement of the adjusting bevel gear 20 and the fixed bevel gear 35, thereby driving the adjusting rotating shaft 19 to start rotating, and the rotation of the adjusting rotating shaft 19 drives the reciprocating screw 13 to start rotating, and the screw rod slider 16 is connected with the screw thread of the screw rod slider 16 through the reciprocating screw rod 13, so that in the continuous rotating process of the reciprocating screw rod 13, reciprocating movement is performed on the reciprocating lead screw 13, and with the reciprocating movement of the lead screw slider 16, the adjusting rod 17 is driven to reciprocate, so that the adjusting seat 18 is driven to reciprocate on the fan-shaped extrusion block 10;

and in the process that the adjusting seat 18 moves back and forth on the sector extrusion block 10, when the adjusting seat 18 moves from the proximal end to the distal end of the sector extrusion block 10, the adjusting seat 18 extrudes the sector extrusion block 10, thereby leading the sector extrusion block 10 to start rotating around the adjusting shaft 11, leading the distance between the sector extrusion block 10 and the lower grinding disc 21 to be reduced, thereby extruding the cement base material between the fan-shaped extrusion block 10 and the lower grinding disc 21, and when the adjusting seat 18 moves from the far end to the near end of the fan-shaped extrusion block 10, at the moment, the adjusting seat 18 is limited by the angle steel type slideway 12, so that the adjusting seat 18 drives the fan-shaped extrusion block 10 to start to rotate reversely around the adjusting shaft 11, thereby increasing the distance between the fan-shaped extrusion block 10 and the lower grinding disc 21 and enabling new cement base material to enter the gap between the fan-shaped extrusion block 10 and the lower grinding disc 21 again;

after the cement base material raw material enters the tapered feed inlet 33 through the feed hopper 32, the cement base material raw material is scattered and falls on the convex tapered surface of the lower grinding disc 21 through the gravity of the cement base material raw material and the rotation of the lower grinding disc 21, then the cement base material raw material is ground through the rotation of the upper grinding disc 3 and the lower grinding disc 21 through the operation of the low-speed drive motor 37, meanwhile, the grinding speed of the cement base material raw material is improved due to the fact that the rotation directions of the upper grinding disc 3 and the lower grinding disc 21 are opposite, in the grinding process of the cement base material raw material, the cement base material raw material is accelerated to move towards the outer ends of the upper grinding disc 3 and the lower grinding disc 21 through the centrifugal force generated by the rotation of the upper grinding disc 3 and the lower grinding disc 21, and therefore the grinding efficiency of the cement base material is guaranteed, in the grinding process of the cement base material, the fan-shaped extrusion blocks 10 extrude the cement base material, so that the cement base material can be sufficiently crushed through the extrusion of the fan-shaped extrusion blocks 10, the grinding efficiency is improved again, and the large cement base material can be quickly ground and crushed;

when the cement base material moves to the outer ends of the upper grinding disc 3 and the lower grinding disc 21 through the rotation of the upper grinding disc 3 and the lower grinding disc 21, the cement base material is ground again through the horizontal plane between the upper grinding disc 3 and the lower grinding disc 21, so that the cement base material is sufficiently crushed, and the crushing effect of the cement base material is ensured;

meanwhile, the circulation fan 28 is also operated, the circulation fan 28 starts to draw air from the fixed sleeve 26 along with the operation of the circulation fan 28, and discharges the air into the circulation air pipe 29 through the output end of the circulation fan 28, and enters the air injection groove 23 above the dividing baffle 25 through the circulation air pipe 29, and then continuously injects the air into the air injection groove 23 above the dividing baffle 25 through the continuous operation of the circulation fan 28, so that the air enters the air injection through holes 24 through the increase of the air pressure and is injected out of the lower grinding disc 21 through the air injection through holes 24, and since the outlet of the air injection through holes 24 is located at the horizontal surface of the lower grinding disc 21, the cement base material after grinding and crushing is discharged out between the upper grinding disc 3 and the lower grinding disc 21 through the injection of the air along with the continuous air injection of the air injection through holes 24, thereby preventing the cement base material from remaining between the upper grinding disc 3 and the lower grinding disc 21, affects grinding efficiency;

the inside of the fixed sleeve 26 generates negative pressure along with the continuous air suction of the circulating fan 28, so that the air below the inside of the box body 1 enters the fixed sleeve 26 through the filter screen 31, and in the continuous operation process of the device, along with the continuous crushing of cement base materials, the air inside the box body 1 carries a lot of cement base material dust along with the work of the circulating fan 28, the cement base material dust in the air is filtered through the filter screen 31, the damage of the cement base material dust to the circulating fan 28 can be effectively avoided, and the cement base material dust can be prevented from blocking the air injection through hole 24;

and the cement substrate after smashing is then discharged from between upper millstone 3 and lower millstone 21 through the flow of air to pile up in the below of box 1 through the flow of air, after the device worked for a period of time, the staff stopped working through control switch control circulating fan 28 and low-speed driving motor 37 this moment, the staff was through the manual discharge valve 43 that opens this moment, the cement substrate raw materials after smashing then discharges through discharge pipe 42 this moment, when discharging the back, alright the device once more carries out the crushing work of cement substrate raw materials this moment.

In the device, along with the rotation of the lower grinding disc 21, through the sliding connection of the fixed sleeve 26 and the air injection groove 23 and the connection of the circulating air pipe 29 and the dividing baffle 25 through the rotating bearing 30, the fixed sleeve 26 can not generate any adverse effect on the rotation of the lower grinding disc 21 while keeping fixed, and meanwhile, although the rotating shaft bearing 30 can generate air leakage problem, the air leakage is greatly lower than the air injection amount of the circulating fan 28, so that the air circulation flow can not be influenced.

In this device, adjust 19 departments of pivot and do not add and establish any mechanism of accelerating rotation, the staff can increase equipment such as acceleration box in 19 departments of adjusting the pivot according to the actual production demand, improves the rotational speed of adjusting the pivot 19, makes the reciprocating rotation frequency of fan-shaped extrusion piece 10 faster to improve crushing effect.

In this device, the staff can increase the grinding line in the corresponding surface department between last mill 3 and lower mill 21 to improve the atress of cement substrate raw materials, thereby make the device crushing effect better.
