[0021] As shown in the accompanying drawings, the utility model includes a ball mill 1, a measuring belt scale 2 and a water inlet pipe 3.

[0022] A feed hopper 4 is provided on the feed port of the ball mill 1, the discharge port of the metering belt scale 2 is connected to the feed hopper 4, the water inlet pipe 3 is installed above the feed hopper 4 through a pipe bracket, and an electromagnetic flowmeter 5 and a pneumatic regulating valve 6 are provided on the water inlet pipe 3, and the water outlet of the water inlet pipe 3 faces the feed port of the feed hopper 4.

[0023] The discharge end of the metering belt scale 2 is provided with a dust cover 7 , and the bottom of the dust cover 7 is flange-connected to the inlet end of the feed hopper 4 .

[0024] A feed port is provided on one side of the dust cover 7 , and the discharge end of the metering belt scale 2 is located in the feed port of the dust cover 7 . A door curtain 8 for blocking dust is provided above the feed port of the dust cover 7 , and the door curtain 8 is located above the metering belt scale 2 .

[0025] A branch outlet pipe 9 is provided at the water outlet end of the water inlet pipe 3 , and a group of sprinkler heads 10 are arranged in sequence at the bottom of the branch outlet pipe 9 .

[0026] A pipe inlet is provided on the top of the dust cover 7, and the water outlet end of the water inlet pipe 3 is located inside the pipe inlet.

[0027] The electromagnetic flowmeter 5 is flange-sealed to the water inlet pipe 3 .

[0028] The ball mill 1 includes a cylinder 11 and a screw feeder 12. The cylinder 11 is installed on a horizontal ground through a pair of bearing seats. The screw feeder 12 is installed at the feed port of the cylinder 11. The feed hopper 4 is installed at the feed port of the screw feeder 12. The outer edge of the cylinder 11 is provided with a ring gear. The motor and the reducer are installed on one side of the cylinder 11. The power output shaft of the reducer is provided with a gear meshing with the ring gear. The cylinder 11 is driven to rotate by the motor and the reducer.

[0029] The feed hopper 4 is a right-angled trapezoidal feed hopper, so that the ore is not easily spilled during feeding.

[0030] Example 1: When the ball mill 1 is feeding, the metering belt scale 2 measures the mass of the ore and transmits the signal to the central control DCS system (distributed control system) in the factory through a transmitter. The electromagnetic flowmeter 5 measures the water entering the water inlet pipe 3 and transmits the signal to the central control DCS system through a transmitter. After receiving the signal, the central control DCS system uses a pre-set water and ore amount ratio algorithm to perform PID (a basic control method of the control system in the classical PID regulating control theory) adjustment according to the ore mass. When the ore mass is large, the water inflow is larger, and when the ore mass is small, the water inflow is smaller.

[0031] When the metering belt scale 2 is discharging, the ore is continuously transported forward, and the dust generated during the discharge is blocked by the door curtain 8. When the ore falls into the feed hopper 4, water is sprayed out through a group of sprinkler nozzles 10 of the branch water outlet pipe 9, thereby adding moisture to the ore and reducing dust.
