Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials from a mill ball feeder, in particular to a novel mill ball feeder. Background Art

[0002] The mill works by grinding materials through the interaction between internal steel balls and the mill chamber wall. Currently, steel balls or forged balls are added to the mill manually. However, manual ball adding consumes a lot of labor and the ball adding is uneven. Therefore, using an automatic ball adding machine to add balls to the mill not only saves labor, but also ensures uniform ball adding and improves the stability of the mill's operation.

[0003] During the process of adding balls to the tube mill, the operator needs to put his arm into the bottom of the steel ball bag and use a wallpaper knife to cut the rope to make the steel balls fall into the mill bin. The steel ball bag may break or operating errors may cause personal injury, which poses a safety hazard and is labor-intensive. Utility Model Content

[0004] The utility model aims to solve the technical problems of safety hazards existing in the prior art ball adding operation and reducing labor intensity by providing a novel ball adding device for a grinding mill.

[0005] To achieve the above-mentioned purpose, a new type of grinding mill ball feeder is provided, comprising: a square funnel, wherein the four corners of the square funnel are provided with conical tripods, the lower end of the square funnel is connected with a discharge port, a plurality of fixed rods are fixedly connected with the inner wall of the discharge port, a support rod is provided in the middle of the square funnel, a cone angle is provided on the upper end of the support rod, and the cone angle is utilized to break the ball bags respectively, so as to facilitate the transportation of materials, reduce the workload, and ensure safety, the upper ends of the plurality of fixed rods are fixedly connected with the outer wall of the support rod, and the conical triangular bracket and the square funnel are composed of two parts, and the position of the steel ball bag is adjusted by an electric hoist to achieve a perfect coordination between manual and mechanical ball adding.

[0006] According to the novel ball adding device for grinding mill, the square funnel is made of iron plate.

[0007] According to the novel mill ball feeder, the inner wall of the square funnel is inclined.

[0008] According to the novel ball feeder for a grinding mill, the side walls of the plurality of conical tripods are respectively fixedly connected to the square funnel and the inner wall of the discharge port.

[0009] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention.

[0010] The purpose of this utility model is to provide a new type of grinding mill ball adding device, the main innovation points are:

[0011] The technology of this device adopts the working principle of the steel ball bag falling by its own weight, which does not damage the steel ball bag and avoids the safety hazard when people use wallpaper cutters to cut the binding rope at the bottom of the steel ball bag. It is easy and labor-saving to operate, reduces the labor intensity of workers, improves the efficiency of adding balls, is easy to operate, steel balls are not likely to spill, and has good safety performance.
