[0027] See Figures 1-5 A raw material crushing device for producing ultrafine aluminum hydroxide includes a grinding chamber 1 and an ultrafine aluminum hydroxide raw material crushing mechanism 2, wherein the ultrafine aluminum hydroxide raw material crushing mechanism 2 is provided on the inner side of the grinding chamber 1.

[0028] The ultrafine aluminum hydroxide raw material crushing mechanism 2 includes an ultrafine grinding component 21 disposed inside the grinding chamber 1, and a primary crushing component 22 disposed above the grinding chamber 1.

[0029] In this invention, the ultrafine grinding component 21 includes a grinding force plate 211 disposed inside the grinding chamber 1. A material leakage hole 212 is disposed in the middle of the grinding force plate 211, and a material conveying plate 213 is disposed below the material leakage hole 212. When it is needed, the raw material being ground by the grinding force plate 211 will gather towards the material leakage hole 212 due to centripetal force and fall onto the material conveying plate 213 for conveying out. This can improve the grinding efficiency and also prevent raw materials exceeding the preset particle size from flowing out, thereby improving the overall planning effect.

[0030] In this utility model, a baffle 214 is provided on the upper outer end of the grinding force plate 211, a material seepage groove 215 is provided in the middle of the baffle 214, and an extrusion plate 216 is provided on the inner side of the material seepage groove 215. A grinding force plate 217 is provided in the middle of the material seepage groove 215, and a rotary motor 218 is provided on the upper side of the grinding force plate 217. When it is needed, the baffle 214, because its height and width are greater than the material seepage groove 215, can prevent the crushed raw materials falling from the crushing chamber 221 from falling to the outside, thereby ensuring that the raw materials will be ground in the subsequent process.

[0031] In this utility model, the extrusion plate 216 and the seepage groove 215 are welded together, the extrusion plate 216 and the seepage groove 215 correspond one-to-one, and the extrusion plate 216 has a triangular structure.

[0032] In this utility model, the rotary motor 218 and the grinding force plate 217 are welded together, and the rotary motor 218 and the grinding force plate 217 form a rotating structure. When needed, the rotary motor 218 can drive the grinding force plate 217 to rotate and grind on the grinding force plate 211, thereby providing sufficient torque to achieve the grinding effect.

[0033] In this invention, the primary crushing component 22 includes a crushing chamber 221 disposed on the upper side of the grinding chamber 1. A driven shaft 222 runs through the middle of the crushing chamber 221. A crushing plate 223 is welded to the upper side of the driven shaft 222, and a pressure tooth 224 is welded to the inner side of the crushing plate 223. When needed, the crushing plate 223 is squeezed inward by the driven shaft 222, and the pressure tooth 224 allows the mineral raw material to be subjected to a certain degree of shear force when it is crushed, which is more conducive to crushing into small pieces. The small pieces will fall through the narrow gap formed in the middle of the driven shaft 222 to achieve the purpose of screening.

[0034] In this utility model, driven wheels 225 are provided on the outer side of the crushing plate 223, and hydraulic pump rods 226 are provided on the outer side of the driven wheels 225. When needed, the hydraulic pump rods 226 will push the crushing plate 223 inward through the driven wheels 225, thereby providing power for the crushing plate 223 to perform crushing and crushing operations and improving the strength of the crushing plate.

[0035] As can be seen from the above technical solution, when in use, the grinding chamber 1 is first placed in the desired position, and then the unprocessed raw material mineral is placed into the crushing plate 223 in the crushing chamber 221. At this time, the two sets of hydraulic pump rods 226 on the left and right simultaneously push the crushing plate 223 through the driven wheel 225, and the crushing plate 223 is squeezed inward along the driven shaft 222. At the same time, the pressure teeth 224 crush the raw material. The raw material crushed to the specified size will fall along the hole in the middle of the driven shaft 222 and fall into the baffle 214 in the grinding chamber 1. As the rotating motor 218 drives the grinding force plate 217 to rotate, the raw material will fall into the seepage tank 215. With rotation, the extrusion plate 216 will crush the crushed raw material here. Finally, after being ground into fine particles by the grinding force plate 217 and the grinding force plate 211, it will flow out through the leakage hole 212 onto the conveying plate 213. In this way, the crushing of ultrafine aluminum hydroxide raw material is completed.
