[0002] Polyurea is a high-performance elastomer material with excellent physical and chemical properties. It is widely used in coatings, waterproofing, corrosion protection, and wear resistance. In the production process of polyurea, pre-dispersion and grinding of polyurea can optimize the uniformity of the material, improve its performance, thereby improving the performance of the final product, reducing production costs, and improving product quality.

[0003] In the prior art, such as the "High-efficiency and rapid grinding machine for polyurea grease" in Chinese patent CN205700723U, this utility model can achieve the effect of uniform and fine grease particle size, good lubrication effect and low mechanical wear by the mutual cooperation of the grinding roller, grinding cylinder, grinding ball and grinding drum.

[0004] Existing methods for grinding polyurea materials employ multiple power sources to drive rotating devices for dispersed grinding. Due to the excessive reliance on external power sources, the energy efficiency of the equipment increases, along with operating and maintenance costs. Furthermore, the uneven power distribution among multiple power sources can lead to inconsistent rotational speeds of the grinding rollers, grinding cylinders, grinding balls, and grinding drums, resulting in uneven material distribution during the grinding process and affecting product quality. Utility Model Content

Furthermore, the uneven power distribution from multiple power sources can lead to inconsistent rotational speeds of the grinding rollers, grinding cylinders, grinding balls, and grinding drums, resulting in uneven material distribution during the grinding process and affecting product quality.

[0006] The technical solution of this utility model is as follows: a high-speed grinding mill for pre-dispersing polyurea materials, including a grinding mill box, a feeding bin welded and fixed to the top surface of the grinding mill box, support feet symmetrically and alternately welded and fixed to the bottom surface of the grinding mill box, a first brush symmetrically and fixedly connected to the inner wall of the grinding mill box, a polymer silo fixedly connected to the inner wall of the grinding mill box, and a transport silo fixedly connected to the inner wall of the grinding mill box, the transport silo being disposed on the bottom surface of the polymer silo.

[0024] A grinding motor 101 is connected and installed on the side of the grinding machine housing 1. A drive shaft 102 and a transmission shaft 103 are rotatably connected inside the grinding machine housing 1. The drive shaft 102 and the transmission shaft 103 are symmetrically distributed inside the grinding machine housing 1. The drive shaft 102 is fixedly connected to the output end of the grinding motor 101, and the transmission shaft 103 is rotatably connected to the inner wall of the grinding machine housing 1. The grinding motor 101 drives the drive shaft 102 to rotate, thereby providing power for the operation of the entire device.

[0025] Crushing rollers 104 are fixedly connected to the outer surfaces of the drive shaft 102 and the transmission shaft 103. Transmission gears 105 are fixedly connected to the outer surfaces of the drive shaft 102 and the transmission shaft 103. The transmission gears 105 mesh with each other. A first drive wheel 106 is fixedly connected to the outer surfaces of the drive shaft 102 and the transmission shaft 103. Power is transmitted through the two sets of meshing transmission gears 105, which can drive the two sets of crushing rollers 104 to rotate synchronously in opposite directions, so as to initially crush and disperse the added polyurea material, reduce the workload of subsequent grinding, and improve grinding efficiency.

[0026] The grinding mill housing 1 is symmetrically connected to a material leveling shaft 107. A material leveling roller 108 is fixedly connected to the outer surface of the material leveling shaft 107. Material leveling grooves 109 are opened at equal angles on the outer surface of the material leveling roller 108, and the material leveling grooves 109 are evenly distributed on the material leveling roller 108. The material leveling shaft 107 drives the two sets of material leveling rollers 108 to rotate synchronously in opposite directions. During the rotation, the material leveling grooves 109 can wrap and hold the pre-crushed polyurea material in the polyurea bin 5. During the continuous rotation, the wrapped polyurea material can be released, allowing the polyurea material to fall into the grinding roller 116 for grinding. The material leveling grooves 109 set at equal angles on the material leveling roller 108 can achieve uniform speed transportation of polyurea material, ensuring uniform grinding of polyurea material.

[0027] A first transmission wheel 110 is fixedly connected to the outer side of one end of the material leveling shaft 107. A first belt 111 is installed on the outer side of the first transmission wheel 110 and the first drive wheel 106. A second drive wheel 112 is fixedly connected to the outer side of the other end of the material leveling shaft 107. The rotating first drive wheel 106 drives the first transmission wheel 110 to rotate through the first belt 111, thereby driving the material leveling shaft 107 and the second drive wheel 112 to rotate, thus transmitting power.

[0028] A grinding shaft 113 is symmetrically rotatably connected inside the grinding machine housing 1. A second transmission wheel 114 is fixedly connected to the outside of the grinding shaft 113. A second belt 115 is connected and installed to the outside of the second transmission wheel 114 and the second drive wheel 112. A grinding roller 116 is fixedly connected to the outside of the grinding shaft 113. A second brush 117 is symmetrically fixedly connected to the inner wall of the aggregate bin 5. The second brush 117 is in contact with the outer surface of the grinding roller 116. The rotating second drive wheel 112 drives the second transmission wheel 114 to rotate through the second belt 115, thereby driving the grinding roller 116 to rotate synchronously in opposite directions through the grinding shaft 113, further grinding and refining the transported polyurea material, so that the polyurea material has a more uniform particle distribution and higher fineness. The second brush 117 in contact with the grinding roller 116 can brush away the polyurea material particles attached to the grinding roller 116, so as to avoid affecting the grinding effect of the grinding roller 116.

[0029] A transport motor 601 is connected and installed on the side of the grinding machine housing 1. The output end of the transport motor 601 is fixedly connected to a transport shaft 602. A spiral transport blade 603 is fixedly connected to the outside of the transport shaft 602. A discharge pipe 604 is provided on the side of the grinding machine housing 1, and the discharge pipe 604 is connected to the transport chamber 6. The transport motor 601 drives the transport shaft 602 to rotate, which drives the spiral transport blade 603 to rotate, thereby transporting the polyurea material that has been ground into the transport chamber 6 and transporting it out of the device through the discharge pipe 604 for collection.

[0030] Working principle: According to Figures 1-5 As shown, during operation, the polyurea material to be ground is added to the grinding chamber 1 through the feeding hopper 2. The grinding motor 101 drives the drive shaft 102 to rotate. The power is transmitted through two sets of meshing transmission gears 105, which drive the transmission shaft 103 to rotate. This drives the two sets of crushing rollers 104 to rotate synchronously in opposite directions, initially crushing and dispersing the polyurea material, reducing the workload of subsequent grinding and improving grinding efficiency. During the rotation of the crushing rollers 104, the first brush 4 can clean the crushing rollers 104 to ensure the crushing effect of the crushing rollers 104.

[0031] The pre-crushed polyurea material particles fall into the polymer bin 5 for collection. The first drive wheel 106 is driven to rotate through the drive shaft 102 and the transmission shaft 103. The power is transmitted through the first belt 111, thereby driving the uniform shaft 107 and the second drive wheel 112 to rotate through the first transmission wheel 110.

[0032] The material leveling shaft 107 drives two sets of material leveling rollers 108 to rotate synchronously in opposite directions. During the rotation, the material leveling groove 109 wraps the initially crushed polyurea material in the polyurea bin 5. During the continuous rotation, the wrapped polyurea material is released and falls onto the grinding roller 116 for grinding. The material leveling groove 109 set at equal angles on the material leveling roller 108 can transport the polyurea material at a uniform speed, ensuring that the polyurea material is ground evenly.

[0033] The rotating second drive wheel 112 drives the second transmission wheel 114 to rotate via the second belt 115, which in turn drives the grinding roller 116 to rotate synchronously in opposite directions via the grinding shaft 113, further grinding and refining the transported polyurea material, so that the polyurea material has a more uniform particle distribution and higher fineness. The second brush 117, which is in contact with the grinding roller 116, can brush away the polyurea material particles attached to the grinding roller 116, so as to avoid affecting the grinding effect of the grinding roller 116.

[0034] The transport motor 601 drives the transport shaft 602 to rotate, which in turn drives the spiral transport blade 603 to rotate, thereby transporting the polyurea material particles that have been ground and entered into the transport chamber 6, and then transporting them out of the device through the discharge pipe 604 for collection.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
