Customer Case | Why an Indian Scrap Recycler Chose the 800 Ton Box Shear for Heavy Ferrous Scrap Processing

Project Overview

A scrap recycling customer in India was planning to upgrade its front-end heavy ferrous scrap processing line. The customer needed a box shear capable of handling bulky mixed scrap, long steel sections, and structural steel offcuts in a more organized way before transport and downstream processing.

During the equipment evaluation stage, the customer compared two box shear options: the QSW-630 and the QSW-800. After reviewing the material profile, loading conditions, and expected working range, our engineering team recommended the QSW-800 hydraulic scrap metal box shearing machine as the more suitable model for the project.

Customer Requirements

The customer’s main concern was not just cutting force in a general sense, but whether the machine could better match actual working conditions on site.

The project involved:

• bulky and irregular ferrous scrap
• long steel sections requiring front-end size reduction
• structural steel scrap rather than only loose light scrap
• repeated industrial-duty operation in a recycling yard environment

For this type of application, model selection needed to be based on feed opening, shearing force, material range, and control mode, rather than machine class wording alone.

Engineering Evaluation

After technical review, our engineers identified three reasons why the QSW-800 was the better fit.

1. Higher Shearing Force for Heavier Scrap Conditions

The QSW-800 is equipped with dual shearing cylinders rated at 4000KN × 2, while the QSW-630 is rated at 3150KN × 2. For heavier ferrous scrap and more demanding structural steel sections, the higher force class provided a broader operating margin.

2. Wider Feed Opening for Bulky Input

The QSW-800 has a 2600 × 1600 mm feed opening, compared with 2600 × 1400 mm on the QSW-630. For bulky and irregular scrap, feed opening width is an important factor because it affects loading convenience and front-end chamber handling. In this case, the wider opening of the 800 ton model better matched the customer’s scrap form.

3. Larger Structural Scrap Capacity

The QSW-800 offers a stronger listed cutting range for profile and solid steel:

• Round steel: Φ160 mm
• Square steel: 130 × 130 mm
• Angle steel: 250 × 250 × 15 mm
• I-beam: 340 × 132 × 15 mm

By comparison, the QSW-630 is listed for:

• Round steel: Φ150 mm
• Square steel: 120 × 120 mm
• Angle steel: 200 × 200 × 15 mm
• I-beam: 320 × 132 × 15 mm

Because the customer needed the machine for larger structural steel scrap as well as mixed ferrous material, the QSW-800 provided a closer match.

The Selected Solution

Based on the engineering review, the customer selected the QSW-800 hydraulic scrap metal box shear.

The machine is configured with:

• dual shearing cylinders
• 4000KN × 2 maximum shearing thrust
• 1350KN clamping force
• 2600 × 1600 mm feed opening
• PLC automatic control with remote control
• 165 kW total installed power

This configuration made it more suitable for the customer’s heavy scrap pre-processing requirements than the smaller model.

Application on Site

In this project, the QSW-800 is used as a front-end pre-processing solution for heavy ferrous scrap. The machine allows bulky and irregular scrap to be loaded into the chamber, secured through the clamping system, and then reduced into shorter sections through hydraulic shearing.

For recycling yard operations, this type of chamber-fed workflow is particularly relevant when the scrap mix includes long sections, profile steel, and oversized input that is not convenient to handle in its original form. The machine’s PLC automatic control and remote control configuration also support repeated-duty operation in an industrial yard setting.

Why This Case Matters

This project reflects a common selection principle in heavy scrap recycling: choosing the right box shear depends on actual scrap conditions, not only on nominal machine class or lower installed power.

The QSW-630 remains a practical option for many medium-to-heavy scrap applications, especially where lower installed power and a more compact footprint are priorities. However, when the customer’s material includes larger structural steel sections and bulkier ferrous input, the QSW-800 can offer a more appropriate engineering match through stronger shearing force, wider feed opening, and a larger listed cutting range.

Conclusion

For this India project, the customer selected the 800 ton box shear based on engineering advice and application fit. The final recommendation was driven by three main factors: stronger shearing force, wider chamber access, and better suitability for heavier structural steel scrap.

For customers comparing 630 ton and 800 ton box shear models, this case shows why parameter-based selection is more useful than broad product labels alone.
