Description

Technical Field

[0001] The utility model relates to the technical field of metal raw material crushing and screening, in particular to a metal block crushing and screening production line. Background Technique

[0002] When smelting titanium alloy, metal simple substances, Binary alloy or multi-element alloy blocks need to be added. Before the above-mentioned blocks are added, they need to be crushed and screened. The purpose is to crush and screen large-sized blocks into qualified particle sizes to avoid quality defects such as non-melting or agglomeration during the use of the above-mentioned blocks as additives, resulting in high-density inclusions.
