Groove type automatic ball feeder for ball mill

Abstract

The invention belongs to the technical field of ball feeding equipment for a ball mill and particularly relates to a groove type automatic ball feeder for the ball mill. The ball feeder comprises a ball storage bin, a ball conveying assembly and a funnel. The ball storage bin comprises a bin body and a buffering ball channel, and an outlet is formed in the buffering ball channel. The ball conveying assembly comprises a ball conveying wheel and a driving assembly, the ball conveying wheel is arranged on the outlet, a rotating shaft penetrates through the middle of the ball conveying wheel, and a plurality of parallel ball conveying channels are arranged on the surface of a wheel body. Each ball conveying channel is provided with a groove and a protrusion, wherein the groove is formed in the front end of the protrusion, the portion from the front end to the tail end of the upper surface of the protrusion is an arc face, the arc face is along the circumference where the ball conveying channels are located, and finally makes contact with the surface of the wheel body. The driving assembly is connected to the rotating shaft, the distance from the surface of the ball conveying ball to the edge of the outlet is smaller than the diameter of steel balls, and each groove contains one steel ball each time. The funnel comprises an inlet end located under the ball conveying wheel, and the funnel conveys the steel balls to the ball mill. The advantages that the grooves are high in ball grasping strength and stable and reliable in operation are used, and accordingly the aim of automatically adding balls is achieved.

Description

technical field [0001] The invention belongs to the technical field of ball mill adding equipment, in particular to a groove type automatic ball adding machine for ball mills. Background technique [0002] At present, most of the ball mills in our country’s concentrators use artificial balls, and there are various ways to add balls: some use a crane to transport the steel balls to the ore feeding end of the ball mill, and the workers throw them into the ball mill by hand; two or three times The ball mill adds small balls, and the workers add small balls into the ball mill with a shovel; some ball mills have a ball adding funnel at the ore feeding end of the second and third ball mills, and the crane lifts the steel balls into the ball adding funnel, and the steel balls are directly rolled into the ball mill, adding The ball system is one overtime per shift. The disadvantage of artificial ball addition is that the amount of added balls is not accurate, and the second is that...

AI Technical Summary

Problems solved by technology

The disadvantage of artificial ball addition is that the amount of added balls is not accurate, and the second is that the addition of balls is not timely, and it is difficult to add steel balls according to the optimal ball ratio.

[0003] A small number of ball mills in mineral processing plants try to use ball adding machines to add balls to the ball mill. At present, most of the ball adding machines for ball mills use disc-type ball adding machines, belt-type ball adding machines, and drum-type ball adding machines. The common disadvantage is that the balls are stuck. , clogging, fluffing, leaking ball, etc.

Some ball feeding machines add a stirring device inside the ball storage bin or a vibration device outside the ball storage bin. Due to the large mass and high friction of the steel balls inside the ball bin, it is easy to cause the motor of the stirring or vibration device to be overloaded and burned, and the outside of the ball storage bin increases The vibrating device sometimes tamps the steel balls in the ball storage bin
