Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to an integrated automatic ball loading machine for ball mills. Background Art

[0002] Ball mills are commonly used in the mining industry, grinding metal ores, nonferrous metal ores, and non-metallic minerals to obtain the desired particle size and mineral grade, providing qualified materials for subsequent processes. Steel balls play a primary role in ball mill operation, serving as the grinding medium. The friction between the steel balls and the material creates a grinding action, making wear-resistant steel balls an essential consumable component.

[0003] When a ball mill is operating, its efficiency generally depends on the total work performed by each steel ball (number of impacts and impact force). Therefore, it is crucial to fully utilize the performance of each steel ball and strictly control the number of steel balls loaded. If the ball load is too high, the steel balls will overlap, preventing the full crushing capacity of each ball and generating internal friction that increases kinetic energy consumption. Conversely, if the ball load is too low, insufficient crushing capacity will affect normal production processes and increase energy consumption. Therefore, strict and stable control of the ball load is essential.

[0004] In order to effectively control the ball loading amount of the ball mill, our company specially designed and developed an integrated automatic ball loading machine. Utility Model Content

An opening is provided at the bottom of the hopper 6, and the opening is connected to the discharge separator 5. The discharge separator 5 is driven by the discharge reducer 4. A slide 11 is provided under the discharge separator 5, and a semicircular groove 12 is connected to the lower end of the slide 11; the conveying device is a conveyor 1, and a horizontally arranged conveyor flat belt 23 is provided on the conveyor 1, and a plurality of conveying rollers are provided under the conveyor flat belt 23, and a weighing roller 24 is provided at the end thereof. The conveyor flat belt 23 is driven by the conveyor belt reducer 3, and the semicircular groove 12 is connected to the conveyor flat belt 23.

[0031] A skirt belt 2 is provided on the conveyor flat belt 23 . The skirt belt 2 is driven by the conveyor flat belt 23 . The steel balls 10 enter the skirt belt 2 from the semicircular groove 12 and move therewith.

[0032] The semicircular groove 12 has an inclination, and the steel ball automatically slides downward in the semicircular groove. A vibration motor 7 is fixed on the semicircular groove to prevent the steel ball from getting stuck.

[0033] Two infrared detectors 8 are also provided on the semicircular groove for detecting the running status of the steel ball 10.

[0035] There are two weighing sensor devices 9, including a sensor base 13 fixed to the outside of the frame on both sides of the conveyor 1. The sensor base 13 uses a sensor fixing bolt 14 to horizontally fix the weighing sensor 15. The lower side of the probe rod of the weighing sensor 15 is fixed to a channel steel 17 with a bracket bolt 18. The upper side of the bracket bolt 18 passes through the probe rod of the weighing sensor 15 and is fixed to the roller bracket 16.
