Description

Technical Field

[0001] This utility model belongs to the field of raw material crushing technology, specifically relating to a crusher for large-particle raw materials. Background Technology

[0002] Graphite crucibles, also known as copper smelting crucibles or copper melting crucibles, are a type of crucible made from graphite, clay, silica, and wax stone. Graphite crucibles are mainly used for smelting non-ferrous metals and their alloys, such as copper, brass, gold, silver, zinc, and lead. Currently, the preparation of graphite crucibles requires the crushing and mixing of various raw materials and the addition of solvents. Existing graphite crucible preparation processes require the raw materials to be crushed first. Current fine crushers use a pendulum type, which achieves the purpose of crushing the raw materials through continuous impact. However, this crushing method not only produces a lot of dust, but also makes it difficult to remove large-diameter particles that cannot be screened out, causing blockages at the screen and leading to increased dust generation. Therefore, we propose a fine crusher for large-particle raw materials to solve the above problems. Utility Model Content

The conical rotating crushing disc 312 has a discharge hole 313 at its center. A connecting frame 314 is connected to the discharge hole 313. Several feeding devices 34 are mounted on a conical fixed crushing disc 33. Several grinding ring positioning grooves 38 are formed on the side of the conical fixed crushing disc 33 near the conical rotating crushing disc 312 and cooperate with the corresponding feeding devices 34. Grinding rings 39 are connected in the grinding ring positioning grooves 38. Each feeding device 34 includes a feeding hopper 35. The conical fixed crushing disc 33 has...
