The recovery of secondary raw materials from post\u2011consumer durable goods \u2014 consisting of ferrous and non\u2011ferrous metals and other materials such as plastics, rubber, glass, fabrics, etc. \u2014 is a relatively recent aspect of recycling. It emerged when durable goods, introduced during the economic boom of the 1960s, began to be discarded in large quantities as they reached the end of their consumption cycle.
\u201cOver time, these complex assemblies of metallic and non\u2011metallic materials have evolved and become increasingly intricate. It is essential to study \u2014 or, more simply, to understand \u2014 these heterogeneous combinations, given their importance as secondary raw materials and the need for more effective recovery actions that influence and guide scrap\u2011processing operations.\nThe recycling supply chain must align with a forward\u2011looking economy, where products are conceived with their end\u2011of\u2011life in mind and scrap is regarded as a resource (sustainable development \u02c3 green economy \u02c3 circular economy).\nRecycling, moreover, is an activity that must combine environmental responsibility with economically sustainable solutions.

<\/p>

HAMMER MILL<\/h3>

Eco\u2011environmental reasons and the new requirements of steelmaking are penalizing the supply of collected scrap, light scrap and end\u2011of\u2011life appliances in their original form, in favor of increasingly clean, homogeneous and contaminant\u2011free materials. The reasons are clear:
\u2022 more stringent environmental regulations,
\u2022 decarbonization targets,
\u2022 economic penalties for contaminated or non\u2011sorted materials
In this scenario, the hammer mill becomes the key machine for transforming \u201cdifficult\u201d scrap into a high\u2011quality secondary raw material, fully compliant with the standards required by modern steel mills.
A hammer mill is designed to volumetrically reduce and separate ferrous and non\u2011ferrous scrap through three main stages: material feeding, impact crushing, and magnetic classification and separation.
The final result must be a clean, compact, and uniform scrap, with consistent density and particle size\u2014ideal for optimizing yield, energy consumption, and overall performance of the electric arc furnace.<\/p>


PRE-SHREDDERS<\/h3>

The scrap pre\u2011shredder emerged as an industrial technology between the late 1980s and early 1990s, when the recycling sector began to require a preliminary material\u2011homogenization stage before its fragmentation in hammer mills.
The horizontal, counter\u2011rotating shaft pre\u2011shredder is designed to operate upstream of hammer mills, ensuring a constant and homogeneous material feed.
It is particularly useful for the pre\u2011processing of body\u2011shell bundles, light or collected scrap, and depolluted end\u2011of\u2011life vehicles (ELVs).<\/p>

The pre\u2011shredder is an essential technology in metal\u2011scrap shredding and sorting plants, for both ferrous and non\u2011ferrous materials, because:
\u2022 It eliminates the root cause of explosions inside the grinding chamber.
\u2022 It reduces and optimises the energy consumption of the shredding process.
\u2022 It prevents absorption peaks by allowing the mill to \u201cdigest\u201d pre\u2011shredded, uniformly sized material.
\u2022 It significantly increases the service life of the wear plates, screens, and hammers of the mill.
\u2022 It upgrades small\u2011scale shredding plants, elevating them to the level of higher\u2011powered systems, enabling them to receive and process complete vehicles as\u2011is and\/or bundled scrap.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
