Technical Field
[0001] The utility model relates to a welded drum feeder, belonging to the technical field of ball mill feeding. Background Art
[0002] Ball mills are widely used in the mining industry, particularly in the mineral processing industry, where they hold significant industrial value. Ball mills are commonly used for grinding, mixing, and dispersing minerals. To accomplish these tasks, the first step is to accurately and precisely deliver the material to the mill via a feeder. The feeder not only ensures uniform material supply but also regulates the feed rate, impacting mill output and ensuring proper operation. Feeder types used in ball mills primarily include chute feeders, drum feeders, and cone feeders. Drum feeders offer advantages such as simple structure, easy maintenance, uniform feed quality, excellent airtightness, wide applicability, and high production efficiency. A drum feeder generally consists of a feeder cover, a guide plate, a guide cone, and a feeder body. Material enters through the cover's circular feed hole, is conveyed by a spiral guide plate inside the cover into the drum, and then is fed into the mill along the guide cone inside the drum. Commonly used drum feeders are mostly castings, which have the advantages of sturdy and durable structure, good anti-spitting design, and suitability for dry feeding. However, this manufacturing method requires specific molds, which limits its application range. In addition, since casting is prone to forming defects such as shrinkage holes and air holes during the cooling process, its quality is uncontrollable. It also has disadvantages such as high replacement and maintenance costs, heavy weight, and long production cycle. Summary of the Invention

As the feeder rotates, the material is transferred to the feeder body 6 in the opposite direction along the cavity formed by the guide plate 2 and the steel plate 3 104 under the action of inertia; and then the material is sent into the mill through the spiral cavity formed by the guide cone 3, the blocking plate 4 and the blade 5.
[0025] The feeder cover 1 includes a flange 101, a steel plate 102, a steel plate 2 103 and a steel plate 3 104 welded together. The steel plate 2 103 is a ring structure, which is welded to the top of the funnel to form a feeding port 7; the guide plate 2 is a curved structure, and multiple guide plates 2 are welded between the steel plate 102 and the steel plate 3 104 to form a spiral structure; the feeder cover 1 is connected to the feeder body 6 by bolts through the flange 101; after the material enters the feeder through the feeder cover 1, the internal spiral structure and rotation characteristics are utilized to realize the feeding of the material.
[0026] The feeder body 6 includes flange 2 601, steel plate 4 602, steel plate 5 603, rib plate 1 604, steel plate 605 and flange 3 606; the blocking plate 4 and the blade 5 are welded first, and then the four groups of components welded by the blocking plate 4 and the blade 5 are evenly welded on the guide cone 3, and then the components welded by the guide cone 3, the blocking plate 4 and the blade 5 are welded together with the steel plate 5 603 to form four groups of cavities; the material is sent out of the tail flange 3 606 through the large mouth of the guide cone 3 as the feeder rotates, and enters the feeding part to complete the material feeding.
[0027] The guide plate 2 is a right-angled triangle curved surface structure, and the surfaces where the two right-angled sides are located are mounting surfaces. The guide plate 2 is welded between the steel plate 1 102 and the steel plate 3 104 through the mounting surfaces.
