The main components of bauxite include aluminum oxide, silicon dioxide, iron oxide, titanium dioxide, etc. Alumina mainly exists in the form of gibbsite, boehmite or diaspore. According to the type of alumina hydrate, it can be divided into gibbsite type, boehmite type, diaspore type or various mixed types.

[0003] Alumina raw materials need to be crushed and ground when they are processed. Currently, the devices for crushing and grinding alumina raw materials are separate individuals, or the two are connected together by a production line. Therefore, they need to be transmitted during crushing and grinding, which wastes time. At the same time, the alumina raw materials cannot be repeatedly ground at one time during grinding.

[0014] Preferably, a feed hopper is fixedly connected to the top of the outer periphery of the shell, and a rotating sealing door is rotatably connected to the outer bottom end of the shell.

[0015] Working principle: When crushing and grinding alumina raw materials, first start the motor. After the output end of the motor rotates, it drives the rotating shaft to rotate. After the rotating shaft rotates, it drives the crushing cone to rotate, so that the alumina raw materials put into the shell from the feed hopper can be crushed. The crushed alumina raw materials fall into the inside of the grinding shell. Since the rotating shaft rotates, it can drive the connecting frame to rotate. After the connecting frame rotates, it can drive the grinding head to rotate. After the grinding head rotates, it can cooperate with the grinding shell to grind the crushed raw materials, and when the grinding particles are smaller than the diameter of the leak plate, they can fall into the shell from the leak plate. When the rotating shaft rotates, the auger can be driven to rotate. The auger cooperates with the outer sleeve to transfer the powder inside the shell to the inside of the grinding shell again, so that the grinding can be continued, making the raw material powder of aluminum oxide finer. At the same time, during grinding, the connecting frame can drive the mounting rod to rotate, thereby driving the anti-blocking cleaning brush and the scraper to rotate. The anti-blocking cleaning brush rotates on the leakage plate to prevent the leakage plate from being blocked, and accelerates the aluminum oxide powder to fall into the shell. At the same time, the scraper can be used to shovel up the powder attached to the top of the leakage plate, and the powder can be turned up from the bottom of the grinding shell, which is convenient for the grinding head to grind;

[0016] When the rotating shaft rotates, it can drive the active bevel gear to rotate. After the active bevel gear rotates, it can drive the driven bevel gear to rotate. The rotation of the driven bevel gear drives the rotating rod to rotate, and the rotating rod drives the eccentric wheel to rotate, so as to drive the top side of the driving rod to rotate, and then the bottom of the driving rod moves up and down, and the driving rod can drive the push-pull rod to move up and down. After the push-pull rod moves up and down, it can drive the movable plug to move up and down. When the movable plug moves upward, the one-way valve one opens and the one-way valve two closes, so that the external air can be sucked into the interior of the cylinder through the one-way valve one. When the movable plug moves downward, the one-way valve one closes and the one-way valve two opens, so that the air in the cylinder can be squeezed into the interior of the gas tank through the inflation connecting pipe. When the air pressure inside the gas tank is too high, the high-pressure gas is discharged through the air bleed pipe and pushes the top cap upward, so that the pressure spring can be compressed. When the air bleed hole moves to the top of the limit ring, the gas will be discharged through the air bleed hole, thereby achieving the effect of pressure relief.

[0017] When it is necessary to clean the inside of the grinding shell, the valve on the ventilation elbow is opened, and the high-pressure gas will enter the inside of the rotating ventilation ring through the ventilation elbow and be sprayed out through the nozzle on the rotating ventilation ring, thereby cleaning the inside of the grinding shell. At the same time, the rotation of the rotating shaft can drive the rotating mounting frame to rotate, and the rotation of the rotating mounting frame can drive the rotating ventilation ring to rotate, thereby driving the nozzle on the rotating ventilation ring to rotate, and then the inside of the grinding shell can be fully cleaned.

[0018] The present invention provides an integrated device for crushing and grinding aluminum oxide raw materials. It has the following beneficial effects:

[0019] 1. The present invention can drive the crushing and grinding mechanism through the rotation of the motor, so the alumina raw material can be crushed and ground in an integrated manner, so there is no need to transport it, which saves the transportation time. At the same time, it can be ground repeatedly to avoid finding that the raw material is unqualified after grinding and then putting it into the device again, thus saving time and improving the processing efficiency of the alumina raw material.

[0020] 2. The present invention provides sufficient air pressure for the powder removing mechanism through the pressurizing mechanism, and can utilize the rotation of the rotating shaft to drive the nozzle to rotate, so as to clean the inside of the grinding shell and prevent the aluminum oxide raw material powder from adhering to the inside of the grinding shell, thereby avoiding the waste of raw materials and saving cleaning time.
