Hydraulic Scrap Shear for Chile Mining Scrap Recycling and EAF Steel Preparation

Case Analysis: Heavy Scrap Pre-Processing for Mining and Industrial Metal Recycling in Chile

Background

Chile has a strong mining and metals background. Public industry data shows that Chile is the world’s leading copper producer and also a major lithium producer, which means mining, equipment maintenance, industrial dismantling, construction, and metal-mechanic activities are important sources of metal-related material flows.

At the same time, Chile’s steel recycling sector is closely connected with ferrous scrap collection and electric arc furnace production. Aceros AZA is described as a major Chilean steel producer using recycled ferrous scrap, with products serving construction, metal-mechanic, and mining-related industries. (EPD International)

For a Chilean scrap recycling yard, the challenge is not only collecting scrap metal. Mining-related and industrial scrap often comes in irregular shapes, long sections, thick plates, structural profiles, and mixed heavy steel pieces. Before these materials can be supplied to local steel recycling, rolling, or EAF-related preparation, they need to be cut into more manageable sizes.

Operational Challenge: Irregular Mining and Industrial Scrap Needs Pre-Processing Before EAF Steelmaking

Mining and Industrial Scrap Is Often Heavy and Irregular

A Chile-based recycling yard may receive scrap from mining maintenance, construction work, steel fabrication, demolition, machinery repair, and industrial dismantling.

Typical incoming materials may include:

• Steel plate offcuts

• Structural steel scrap

• Round steel scrap

• Square steel scrap

• Heavy melting scrap

• Machinery frame scrap

• Industrial dismantling steel waste

These materials are not always uniform. Some pieces may be too long, too wide, or too bulky for direct furnace charge preparation or downstream processing.

Manual Cutting Is Not Ideal for Repeated Heavy Scrap Processing

Manual cutting can be used for some oversized scrap, but it is not suitable as the main processing method when a recycling yard handles repeated heavy scrap flows.

For Chilean recycling yards serving mining-related and industrial scrap sources, the equipment needs to support a more structured workflow: loading, pressing, pushing, and shearing.

This is where a hydraulic scrap shear becomes useful. It allows oversized steel scrap to be reduced into shorter sections before stock preparation, resale, transportation, or EAF-related material preparation.

EAF Steel Preparation Requires Better Scrap Size Control

Chile’s steel recycling direction is increasingly connected with recycled ferrous scrap and EAF-based production. Recent public reports also mention green steel projects in Chile using recycled scrap metal and electric arc furnace technology. (New Energy Events)

For this type of supply chain, scrap size control matters. Oversized and irregular scrap can create extra handling work before melting-related preparation. A recycling yard that can pre-process heavy scrap more consistently is better positioned to serve local steel mills, rolling mills, and industrial metal users.

Chile Buyer Preference in Equipment Selection

For Chile mining and industrial scrap recycling applications, buyers usually care about practical working conditions rather than broad marketing claims.

For this reason, a Chile-oriented case should focus on measurable configuration: shearing capacity, cylinder thrust, feeding box size, hydraulic pressure, cutting range, and oil cooling system.

Recommended Solution

For this application, the Q91Y-700W Hydraulic Scrap Steel Shearing Machine with Cover is suitable as a heavy scrap pre-processing machine for Chile mining and industrial scrap recycling yards.

The machine is designed with 700 tons shearing capacity, two YG420/300 shearing cylinders, and each shearing cylinder provides 3500KN full thrust. It also has a 7500×1600×800 mm feeding box, which is suitable for loading long, bulky, and irregular scrap steel before hydraulic pushing and shearing.

The machine also includes a hydraulic cover pressing system. According to the technical sheet, it uses three YG160/100 door cover cylinders, each with 500KN full thrust and 920 mm stroke. This structure helps press loose or uneven scrap before cutting, which is useful for structural steel, plate offcuts, and mixed industrial scrap.

Key Technical Configuration

Material Suitability

The Q91Y-700W is suitable for steel materials within the stated strength condition of Δb≤450 MPa.

According to the technical file, the maximum cutting ranges are:

These values are important for Chilean buyers because mining-related and industrial scrap may vary in thickness, cross-section, and steel grade. For high-strength steel, alloy steel, stainless steel, or unusually shaped scrap, the material details should be checked before confirming the final machine configuration.

How the Machine Fits a Chile Scrap Yard Workflow

Step 1: Loading Mining and Industrial Scrap

The operator loads long or irregular scrap into the 7500 mm long feeding box using suitable site handling equipment, such as a crane, grab, or forklift, depending on the yard layout.

Step 2: Pressing Bulky Scrap Before Cutting

The cover pressing system helps control loose or uneven scrap before shearing. This is useful for structural scrap, heavy plate offcuts, machinery frames, and mixed industrial materials that may not lie flat in the feeding box.

Step 3: Hydraulic Pusher Feeding

The YG220/160 push cylinder with 7500 mm stroke pushes the scrap toward the shear opening. This supports a more controlled pre-processing flow compared with repeated manual repositioning.

Step 4: Heavy-Duty Shearing

The twin shearing cylinders provide the force for cutting heavy scrap into shorter sections. The processed material is easier to handle, store, transport, or prepare for steel recycling and EAF-related applications.

Expected Operational Value

For a Chilean scrap recycling yard, the value of this machine comes from matching heavy mining and industrial scrap conditions with a structured hydraulic process.

The machine supports:

• Pre-processing of mining-related steel scrap

• Heavy scrap size reduction before EAF steel preparation

• More controlled cutting of irregular and bulky materials

• Easier handling of steel plate, round steel, square steel, and structural scrap

• Reduced dependence on manual cutting for repeated yard processing

• Better stock preparation for recycling yards, steel mills, and metal processing plants

These benefits are supported by specific machine parameters, including 700 tons shearing capacity, 3500KN × 2 shearing cylinder thrust, 7500×1600×800 mm feeding box, and 25 MPa hydraulic system pressure.
