Description

Technical Field

[0001] This utility model relates to the field of mining engineering technology, and more specifically, to a ball mill feed scoop. Background Technology

[0002] Ball mills are key equipment in mineral processing, primarily used for deep grinding of raw ore (fine ore). The scoop head is responsible for scooping the slurry into the ball mill. Because the scoop head moves in a circular motion during operation, its top is in direct contact with the ore, resulting in severe wear and a short service life, typically requiring replacement every two weeks. Replaced scoop heads cannot be repaired and must be scrapped. This not only affects the normal production and technical performance improvement of the mineral processing plant but also increases the number of unauthorized shutdowns, thereby raising production costs. Furthermore, if the ore scooping volume is insufficient during ball mill operation, splashing can easily occur. Utility Model Content

[0003] The purpose of this invention is to provide a ball mill feed scoop head that solves the problem of easy wear of existing scoop heads.

[0004] This utility model is achieved through the following technical solution: a ball mill feeder scoop head, including a scoop head, with a wear-resistant component detachably connected to the end of the scoop head. The wear-resistant component includes a middle tooth and side teeth. The end of the scoop head is inserted into the middle tooth, and the side teeth abut against the inner walls on both sides of the end of the scoop head.

[0005] Furthermore, a baffle is provided on the outside of the scoop head for the wear-resistant part.

[0006] Furthermore, the intermediate teeth consist of several teeth arranged side by side.

[0007] Furthermore, the outer surface of the intermediate teeth is arranged at an angle.

[0008] Furthermore, both the spoon head and wear-resistant parts are made of wear-resistant steel NM360.

[0009] Furthermore, the wear-resistant parts are fastened to the spoon head with bolts.

[0010] This invention has at least the following advantages and beneficial effects: By setting the middle tooth and the side tooth, which wrap around the end of the scoop head, it can better guide the ore feed, reduce the impact of the ore on the scoop head during the feeding process, reduce wear, make the scoop head more durable, improve the service life of the device, and reduce production costs. At the same time, when scooping slurry, it can also avoid splashing, ensuring the ore feed rate of the ball mill. Attached Figure Description

[0016] The specific implementation method is described below with reference to the accompanying drawings.

[0017] Example

[0018] like Figures 1-4 As shown in this embodiment, a ball mill feed scoop head is disclosed, including a scoop head 1. A wear-resistant component 2 is detachably connected to the end of the scoop head 1. The wear-resistant component 2 includes a central tooth 21 and side teeth 22. The end of the scoop head 1 is inserted into the central tooth 21, and the side teeth 22 abut against the inner walls on both sides of the end of the scoop head 1. Specifically, the wear-resistant component 2 has a semi-enclosed structure, which can better guide the feed and reduce the impact of the ore on the scoop head 1 during the feeding process, thus reducing wear. By setting the central tooth 21 and side teeth, the scoop head 1 is wrapped around the end and the end of the scoop head 1 is thickened, making the scoop head 1 more durable. This effectively improves the service life of the device and reduces production costs. At the same time, when scooping slurry, it can also avoid splashing, ensuring the feed rate of the ball mill.

[0019] Furthermore, in a specific implementation, the wear-resistant part 2 provided in this utility model embodiment is provided with a baffle 3 on the outside of the spoon head 1, which helps to hold the slurry.

[0020] Furthermore, in a specific implementation, the intermediate tooth 21 provided in this embodiment of the present invention is composed of several bucket teeth arranged side by side. Specifically, the bucket teeth can be loader bucket teeth in the prior art, one end of which is pointed and the other end has an installation slot in the middle to cooperate with the end of the scoop head 1.

[0021] Furthermore, in a specific implementation, the outer surface of the intermediate tooth 21 provided in this embodiment of the present invention is arranged at an angle. Specifically, the angle of inclination can be 20° to 30°, which helps to increase the amount of ore scooped, while reducing the friction between the scoop head 1 and the slurry, thus increasing the service life of the scoop head 1.

[0022] Furthermore, in specific implementations, both the spoon head 1 and the wear-resistant part 2 provided in this embodiment of the present invention are made of wear-resistant steel NM360. This provides advantages such as high strength, high hardness, and wear resistance.

[0023] Furthermore, in specific implementation, the wear-resistant part 2 provided in this embodiment of the present invention is fastened to the spoon head 1 by bolts. Specifically, bolt holes are provided at corresponding positions on both the spoon head 1 and the wear-resistant part 2. During installation, the bolt holes on the spoon head 1 are aligned with the bolt holes on the wear-resistant part 2, and then bolts are inserted for fastening. In addition, the spoon head 1 and the wear-resistant part 2 can be further fixed by spot welding after connection.
