[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-6 As shown, this utility model embodiment provides a clinker high-efficiency grinding and energy-saving device, including a ball mill cylinder 1, which is divided into a first ball mill chamber 11, a second ball mill chamber 12, and a third ball mill chamber 13; a cooling system 5 installed on the ground is provided on one side of the ball mill cylinder 1, and a spray assembly 6 is provided on the outside of the ball mill cylinder 1. The cooling system 5 is used to generate cooling water and transport it to the spray assembly 6, and the spray assembly 6 sprays water onto the outer surface of the ball mill cylinder 1 to cool it down; a collection box 7 is provided below the ball mill cylinder 1, which is used at least to collect the water that has exchanged heat with the ball mill cylinder 1 and circulate it to the cooling system 5; a plurality of chamber plate partitions 8 are provided inside the ball mill cylinder 1, which divide the internal space of the ball mill cylinder 1 to form a first ball mill chamber 11, a second ball mill chamber 12, and a third ball mill chamber 13.

[0029] In this embodiment, as Figure 1 and 4As shown, the mill includes a ball mill cylinder 1, which is divided into a first ball mill chamber 11, a second ball mill chamber 12, and a third ball mill chamber 13. Steel balls are respectively installed inside the first ball mill chamber 11, the second ball mill chamber 12, and the third ball mill chamber 13. The split-type ball mill cylinder 1 is more conducive to the full grinding of raw materials, while achieving the effect of energy saving and consumption reduction.

[0030] Specifically, such as Figure 4 As shown, the diameters of the steel balls in ball milling chambers 11, 22, and 313 are φ40mm-80mm, φ80mm-120mm, and φ20mm-40mm, respectively. The preferred diameters of the steel balls in ball milling chambers 11, 22, and 313 are φ60mm, φ100mm, and φ30mm, respectively. The proportion of small balls to large balls in each chamber is 4%. The weight deviation of ball milling chambers 11 and 313 is ≤3%, thereby achieving efficient grinding and reduced consumption during the ball milling of cement raw materials.

[0031] In this embodiment, as Figure 1 , 2 As shown in Figure 6, a cooling system 5 installed on the ground is provided on one side of the ball mill cylinder 1. The cooling system 5 is used to generate cooling water and deliver it to the spray assembly 6. The cooling system 5 uses the spray assembly 6 to cool the ball mill cylinder 1 to a temperature below 40°C.

[0032] Specifically, the cooling system 5 includes a water tank 51. A water pump 52 is installed on one side of the water tank 51 through a pipe. The water pump 52 transports the condensate inside the water tank 51 to the spray assembly 6. The collection tank 7 collects the cooled water and transports it back into the water tank 51. First, water is added into the water tank 51. After the water cup evaporator 53 and the water pump 54 inside the water tank 51 process it into cooling water, the water inside the water tank 51 is pumped to the spray assembly 6 by the water pump 52 and the ball mill cylinder 1 is cooled down by the collection tank 7.

[0033] Specifically, a second water pump 54 is installed on one side of the water tank 51 via a pipe, and an evaporator 53 is installed on one side of the second water pump 54. The second water pump 54 transports water from inside the water tank 51 to the evaporator 53 via a pipe, and the water in the evaporator 53 flows back to the inside of the water tank 51 via a pipe. The evaporator 53 and the condenser 55 exchange heat, cooling the water circulating through the second water pump 54, so that the inside of the water tank 51 receives a continuous supply of condensate, thereby achieving the cooling effect on the ball mill cylinder 1.

[0034] Specifically, a condenser 55 is provided on one side of the evaporator 53. One end of the condenser 55 is connected to a water pump 56 via a pipe. The water pump 56 is connected to a cooling tower 57 via a pipe. One side of the cooling tower 57 is connected to the condenser 55 via a pipe. The water pump 56 transports water from inside the cooling tower 57 to the condenser 55, where the condenser 55 achieves heat exchange with the evaporator 53.

[0035] In this embodiment, as Figure 1 and 3 As shown, a spray assembly 6 is provided on the outside of the ball mill cylinder 1. The spray assembly 6 sprays water onto the outer surface of the ball mill cylinder 1 to cool it down. The spray assembly 6 includes a shell 61 fitted over the ball mill cylinder 1. Corrugated covers 62 are provided on both sides of the shell 61 to slide in contact with the ball mill cylinder 1. When the ball mill cylinder 1 rotates, the corrugated covers 62 can ensure the sealing between the shell 61 and the ball mill cylinder 1, preventing water from splashing onto the outside of the shell 61. A water supply pipe 63 is fixedly installed on the top of the shell 61, and a water distribution pipe 64 connected to the water supply pipe 63 is provided inside the upper part of the shell 61. Several nozzles 65 are provided on the outer wall at the bottom of the water distribution pipe 64. Cooling water is transported to the water distribution pipe 64 through the water supply pipe 63 and sprayed downwards evenly by the nozzles 65. The condensed water splashes onto the outer surface of the ball mill cylinder 1, thereby cooling the surface of the ball mill cylinder 1.

[0036] In this embodiment, as Figure 1 and 2 As shown, a collection box 7 is provided below the ball mill cylinder 1. The collection box 7 is used at least to collect the water that has exchanged heat with the ball mill cylinder 1 and to circulate it to the cooling system 5.

[0037] In this embodiment, as Figure 1 , 4 As shown in Figure 5, the interior of the ball mill cylinder 1 is provided with several chamber plate partitions 8, which divide the internal space of the ball mill cylinder 1 to form ball mill chamber one 11, ball mill chamber two 12 and ball mill chamber three 13. The partition plate 8 includes a sleeve 81 inserted into the inner joint of the ball mill cylinder 1. A partition plate 82 is fixedly installed in the middle of the sleeve 81, which divides the ball mill cylinder 1 into ball mill chamber 11, ball mill chamber 2 12 and ball mill chamber 3 13. Several guide vanes 83 are provided on the inner walls of both sides of the sleeve 81. A material guide hole is provided at the center of the partition plate 82, and a stabilizing frame 84 is provided inside the material guide hole. A filter screen 85 is installed on the stabilizing frame 84. As the ball mill cylinder 1 rotates, the raw material with the qualified particle size after ball milling flows along the guide vane plate 83 and enters the interior of ball mill chamber 2 12 through the filter screen 85. The raw material continues to be ball milled inside ball mill chamber 2 12 and then enters the interior of ball mill chamber 3 13.

[0038] In this embodiment, as Figure 1 As shown, support components 2 are provided at both ends of the ball mill cylinder 1. The support components 2 are used to provide stable support for the ball mill cylinder 1. A drive device 3 for driving the ball mill cylinder 1 to rotate is provided on the outside of one of the support components 2. A feed hopper 4 is provided at one end of the ball mill cylinder 1. Raw materials are added into the feed hopper 4 and transported to the inside of the ball mill cylinder 1 through the pipe below it.

[0039] Working principle: The worker adds the raw material into the ball mill cylinder 1 through the feed hopper 4. The drive device 3 drives the ball mill cylinder 1 to rotate, thereby rotating the steel balls and raw material inside, realizing the ball milling operation. At the same time, the cooling system 5 is activated, so that the circulating cooling water is sprayed onto the surface of the ball mill cylinder 1 through the spray assembly 6 to cool the ball mill cylinder 1 and control it below 40°. The water falling from the spray enters the collection box 7 and is recycled back into the cooling system 5 to realize the circulation of cooling water. Since the raw material added into the ball mill cylinder 1 is located inside the first ball mill chamber 11, as the particle size of the raw material decreases, it will enter the second ball mill chamber 12 through the partition plate 8 between the first ball mill chamber 11 and the second ball mill chamber 12, and then enter the third ball mill chamber 13 in the same way, realizing the multi-chamber ball milling operation.
