Description

Technical Field

[0001] The utility model relates to the technical field of metal waste recycling, in particular to a dust-proof crusher for metal waste recycling and processing. Background Art

[0002] Scrap metal, also known as used and discarded metal, is an important source of raw material for the production of industrial metals and alloys, particularly steel, copper, lead, aluminum, and zinc. Small amounts of tin, nickel, magnesium, and precious metals can also be recovered from scrap metal. Organic impurities in scrap metal, such as wood, plastic, paint, and fabric, can be burned. Metallic impurities can be useful, inert, or harmful. Harmful impurities can be diluted to acceptable concentrations by adding pure metals or removed during refining. Scrap metal is typically compounded and remelted to produce alloys with similar or higher composition. Scrap metal recycling requires pulverization of the scrap metal pieces. Existing equipment for pulverizing scrap metal pieces easily generates large amounts of dust, which can pollute the operating environment and be inhaled by operators, causing harm.

[0003] When existing equipment performs metal scrap crushing operations, it usually directly puts metal parts into the crushing process without pre-crushing the metal parts, resulting in reduced efficiency of the metal parts crushing process and easy damage to the equipment. During the metal parts crushing process, a large amount of dust is easily generated to pollute the operating environment, and operators are prone to inhaling dust and causing harm to their bodies. Therefore, technical personnel in this field provide a dust-proof crusher for metal scrap recycling and processing to solve the problems raised in the above background technology.
