[0002] Publication No. CN214347112U discloses an abrasive device for cement production, including an abrasive device, a support plate fixedly connected to the upper left end of the abrasive device, an alarm fixedly connected to the lower end of the support plate, a water tank fixedly connected to the upper end of the support plate, and the water tank is fixedly connected to the abrasive device, the inner left end of the water tank is fixedly connected to a liquid level gauge through a fixed rod, a water pump is fixedly connected to the left side of the upper end of the abrasive device, and a water pipe is fixedly connected to the inner upper end of the abrasive device. This device is provided with a water tank, a water pump, a liquid level gauge, a water pipe and an alarm. When the water pump is running, water in the water tank on the support plate is pumped out and the water is pumped into the water pipe in the abrasive device. Finally, water is sprayed out from the spray hole on the water pipe to clean the stains on the inner wall of the abrasive device. This arrangement is convenient for cleaning the abrasive device and prevents the remaining cement raw materials in the abrasive device from affecting the quality of the next batch of raw materials. However, the patent still has the following problems in actual use:
