The scrap metal shearing machine, often nicknamed the "tiger shear" for its powerful cutting jaws, is a cornerstone piece of equipment in the metal recycling and scrap processing industry. Its primary function is to use immense hydraulic force to cut, compress, and densify various forms of ferrous and non-ferrous scrap—such as demolition steel, vehicles, appliances, and industrial waste—into clean, manageable pieces ideal for steel mills and foundries. This process is fundamental for efficient recycling, transforming bulky, low-density scrap into a high-quality furnace-ready raw material.   At its core, a scrap metal shear operates on a simple yet powerful principle. The machine typically consists of a large feed box, a hold-down cylinder, and a massive moving blade (the "jaw") that works against a fixed blade. The process is highly systematic:   1. Loading: Loose scrap is loaded into the machine's feed box or chamber.   2. Compaction & Holding: A powerful hydraulic hold-down cylinder descends to compress and firmly secure the material. This is critical for safety, preventing material from shifting or "kicking back" during the cut.   3. Shearing: The main hydraulic cylinders then drive the moving blade (often in an upward or horizontal motion) with tremendous force—often measuring in hundreds or thousands of tons—to shear through the metal against the stationary blade, much like a pair of giant scissors.   4. Ejection: After the cut, the hold-down releases, and the sheared, densified "log" or bale is ejected, ready for transport.   Modern shears are controlled by Programmable Logic Controllers (PLCs), enabling semi-automatic or fully automatic cycling for continuous, efficient operation.   Main Types and Key Advantages   Shears are broadly categorized by their structure and optimal use case:   • Alligator Shear: Named for its scissor-like, hinged jaw movement reminiscent of an alligator's bite. It is more compact and cost-effective, ideal for smaller yards processing lighter scrap like rebar, sheet metal, and structural beams.   • Guillotine Shear (or Box Shear): Features a large box-like feed chamber and a blade that moves vertically (like a historical guillotine) or horizontally within a solid "gate" or frame. It excels at processing heavier, bulkier materials like entire car bodies, large industrial equipment, and thick plate due to its greater chamber size and holding force.   The advantages of using a shear are transformative for the recycling workflow:   • Volume Reduction: Sheared scrap can occupy up to 70% less space, drastically cutting storage and transportation costs.   • Improved Quality: Produces clean, dense "furnace-ready" bundles that melt more efficiently in electric arc or basic oxygen furnaces, reducing energy consumption and impurities.   • Enhanced Safety & Environment: Replaces dangerous and pollutin...

  Container shears are heavy-duty industrial equipment primarily used to compress and shear various metal scraps (such as steel sections, plates, auto bodies, and lightweight materials) into high-density "blocks" for easier transportation, storage, and improved smelting efficiency. Before starting work each day, the following checks must be performed:   1. Cleaning and Visual Inspection   Remove debris: Remove dust, oil, metal shavings, and other debris from the equipment surface, around the blades, and the feed chute. Keeping the equipment clean prevents debris from affecting cutting accuracy and damaging the equipment.   Visual Inspection: Visually inspect all parts of the equipment for obvious damage, cracks, or deformation.   2. Lubrication Check   Check Oil Level: Check that the hydraulic oil level in the hydraulic system is within the range specified on the oil level gauge. If the oil level is too low, add hydraulic oil of the same grade immediately.   Check Lubrication Points: Add an appropriate amount of grease or lubricating oil to all lubrication points specified in the equipment manual (such as slide rails, bearing seats, pins, etc.). Ensure that moving parts are well lubricated.   3. Fastener Inspection   Check Critical Bolts: Focus on checking the tightness of critical parts such as anchor bolts, blade fixing bolts, and hydraulic line joints to ensure there is no looseness. Looseness can lead to increased vibration, increased noise, and even accidents.   4. Electrical System Inspection   Inspect Wiring: Visually inspect cables and wires for damage, aging, or exposed wires.   Inspect Operating Buttons: Test the sensitivity and reliability of all operating buttons (such as start, stop, up, down). The emergency stop button must function effectively.   5. Blade Inspection   Inspect Blade Edges: Check the sharpness of the upper and lower blades, ensuring there are no chips, curled edges, or severe wear. Dull blades will reduce shearing quality and increase equipment load.   6. No-Load Trial Run   Before starting formal work, start the equipment and perform several no-load shearing cycles. Listen to the equipment's operating sound to ensure it is normal, and observe the hydraulic system for any abnormal vibrations or leaks. Work can only begin after confirming everything is normal.

Discharge System:   Conveyor: Transports the shredded material away.   Magnetic Separator (Optional but Important):Used to separate metallic and non-metallic impurities.   Dust Collection System (Environmental Requirements): Collects dust generated during the shredding process, meeting environmental standards.   4. Control System:   PLC Control: High degree of automation, capable of monitoring load, setting automatic reverse (anti-jamming), and fault alarms.   Electrical Cabinet: Core control unit.

The horizontal baler stands as a cornerstone equipment within the waste management and recycling sector. Its work principle involves using hydraulic power to compress materials. When materials are fed into the baler, a hydraulic cylinder exerts immense pressure, gradually squeezing the materials together. As the pressure builds up, the materials are compacted into tightly packed bales.   Engineered to compress an array of materials, including cardboard, paper, plastics, and even metals, into tightly packed bales, it dramatically diminishes waste volume. This reduction enhances the efficiency and cost-effectiveness of both storage and transportation processes.   A primary benefit of horizontal balers lies in their remarkable versatility. They are capable of processing a diverse spectrum of materials, effortlessly adjusting to varying sizes and shapes. This adaptability renders them suitable for a multitude of industries, spanning from manufacturing to retail operations.   Furthermore, horizontal balers are renowned for their impressive compression ratios, guaranteeing that the bales they produce are both dense and stable. This not only conserves valuable space but also significantly reduces the likelihood of bales disintegrating during handling and transportation.   After each day's work is completed, it's the best time for maintenance:   Thorough Cleaning: Remove any remaining paper scraps and debris from the hopper. Clean dust and oil from the pusher head, compression chamber, and bale outlet. Clean the equipment surface, keeping it clean overall.   Inspect Key Components:   Blades and Seals: Check the sealing strips on the compression chamber door for damage. Replace any damaged strips immediately to prevent leakage. Check the sharpness of the cutter.   Chain/Wire Rope:  For equipment using chains or wire ropes for threading, check their wear and tension, and add appropriate amounts of lubricating oil.   Lubrication: Add the specified grease or lubricating oil to all lubrication points (such as guide rails, sliders, bearing housings, etc.) according to the equipment manual.   Hydraulic System: After shutting down, check again for any leaks. Clean the area around the oil tank filler neck to prevent impurities from entering.   In essence, the horizontal baler assumes a critical role in contemporary waste management strategies. Its efficiency, adaptability, and superior compression abilities render it an indispensable tool for businesses seeking to optimize their waste disposal and recycling workflows.
