[0002] A ball mill is a key device for crushing materials after they have been crushed. It consists of a feeder, a discharger, a rotary unit, and a transmission unit (reducer, transmission gears, motor, and electronic control). Materials enter the ball mill from the feeder for milling.

[0003] The current ball mill feed system primarily controls the feed rate by manually opening and closing a valve plate. Due to the uneven shape and size of the aluminum ash raw material, the feed rate during the ball milling process is unstable. Large feed rates result in low aluminum particle content, while small feed rates cause significant wear on the mill's liner, shortening its lifespan. Consequently, workers are required to frequently adjust the feed rate, which is labor-intensive. Summary of the Invention

[0004] The utility model aims to solve the problems of unstable feeding and heavy labor of workers in the existing ball mill feeding device, and provides a stable feeding device for aluminum ash slag ball mill, which makes the feeding amount of the ball mill stable, improves production efficiency and reduces the labor intensity of workers.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A stable feeding device for aluminum ash slag into a ball mill is installed above the ball mill and includes a silo. A vibrating feeder and a weighing belt are connected in sequence between the silo and the ball mill. A discharge port is provided at the bottom of the silo, and the vibrating feeder is located below the discharge port. One end of the weighing belt is located below the discharge port of the vibrating feeder and the other end is located above the feed port of the ball mill. The material passes through the silo, vibrating feeder, and weighing belt in sequence before entering the ball mill.

[0007] Furthermore, an electro-hydraulic gate valve is provided on the discharge port of the silo, through which the opening and closing of the silo can be remotely controlled.

[0008] Furthermore, the silo is detachably connected to a vibrating feeder, which is connected below the silo.

[0009] Furthermore, a hanging rope is provided on the outer wall of the silo, and a hook matching the hanging rope is provided on the outer wall of the vibrating feeder. The vibrating feeder is connected to the silo via the hanging rope.

[0010] Furthermore, the vibrating feeder includes a trough body and an electromagnetic vibrator. The trough body is arranged horizontally and has a feed port and a discharge port. The feed port is connected to the discharge port of the silo. A weighing belt is arranged below the discharge port. The electromagnetic vibrator is arranged outside the trough body. The material passes through the vibrating feeder and reaches the weighing belt from the trough body.

[0011] Furthermore, the electromagnetic vibrator is electrically connected to the signal output terminal of the weighing belt. The electromagnetic vibrator adjusts the vibration frequency according to the signal value input by the weighing belt, thereby adjusting the feed rate of the weighing belt, so that the real-time weight of the weighing belt is stabilized within the production requirement range.

[0012] Furthermore, the weighing belt includes a belt conveyor and an electronic belt scale, and the electronic belt scale is used to detect the weight of the material transported on the belt conveyor.

[0013] Through the above technical solution, the beneficial effects of the utility model are:

[0014] The utility model arranges a vibrating feeder and a weighing belt between the hopper and the ball mill. The vibrating feeder feeds the materials and the weighing belt measures the materials, so that the weight of the materials entering the ball mill is stabilized within the production requirement range.
