EXPLOSION & FIRE 💥🔥 inside the Pre-Shredder. Sprinkler System in Action 💦 | Scrap Yard in Preston

Описание: Welcome to the biggest scrap yard in Preston — where heavy steel meets heavy machinery.
In this video, you’ll see Sennebogen and Fuchs scrap handlers working full tilt, loading and moving metal into the shredder, plus some serious industrial power in action.

A loud explosion occurred inside the pre-shredder. A fire broke out, but the built-in sprinkler suppression system activated instantly and took control.
Everyone on-site was safe.

According to an online article by Blog Preston, Global Ardour see two to three small fires each week which need containing & the cause of the 'pop' was likely to be a Lithium battery

What’s in the video:
• Sennebogen & Fuchs scrap handlers feeding the shredder
• Massive piles of scrap being processed
• The explosion and fire event (caught on camera)
• Sprinkler system activating and shutting the fire down
• Real industrial scale metal recycling in action

SOME INFO ON THE PRE-SHREDDER:
A pre-shredder (often used in scrap metal and recycling lines) is primarily designed to roughly break down material before it enters the main high-speed shredder, but one of its key roles is safety—especially reducing explosion and fire risks.

💥Why explosions happen in shredders

When cars, appliances, or mixed scrap go directly into a high-speed shredder, there may still be:
• Sealed containers (e.g., gas cylinders, aerosols, fuel tanks)
• Residual flammable liquids or vapors
• Lithium batteries
• Pressurized components

A main shredder runs at very high speed and produces sparks. If any of the above materials rupture there, you can get:
• Flash fires
• Dust explosions
• Serious damage to the shredder

⚙️Function & Purpose
Opens and decompresses sealed or pressurized items
Prevents explosions in the main shredder
Breaks material into manageable chunks
Ensures smooth, constant feed to the main shredder
Reduces peak loads
Protects downstream shredding equipment from shock loading
Removes or separates hazardous/undesirable components e.g., fuel tanks, batteries, airbag charges
Lowers ignition risk
Slower rotation → fewer sparks → lower fire likelihood

🔥How It Improves Fire & Explosion Safety
• Any ignition event is smaller because less energy is involved at this stage.
• By the time material reaches the main shredder:
• Pressurized items are already burst open
• Flammable vapors have dissipated
• Hazardous parts can be removed

Pre-shredders act as the “safety buffer,” handling dangerous break-open events before the main shredder.

In Practical Terms
❌Without a pre-shredder, operators see:
• More fire suppression activations
• More shredder damage or downtime
• Higher insurance and compliance costs

✅With a pre-shredder:
• Process is more stable and predictable
• Main shredder consumes less power
• Operational risk is significantly reduced
