Blue Storm: the Light Scrap Shredder by Zato
The Blue Storm is an intelligent light scrap shredder that transforms lightweight scrap into a valuable resource. Its 4-motor hydraulic configuration, specialised interchangeable blade system and robust construction ensure outstanding performance and safe operation. With shafts operating at differentiated speeds, the Blue Storm maximises material processing while downsizing light scrap to increase its density. Compact yet powerful, it is the answer for yards that need to handle high volumes of thin, bulky or mixed light metal without compromising on reliability or on the quality of the material sent downstream.
Engineered as a high-output twin shaft shredder
The Blue Storm belongs to Zato’s family of two shaft industrial shredders, where a low-speed, high-torque cut does the hard work instead of brute speed. As a twin shaft shredder it pairs two synchronised rotors that pull material in and shear it cleanly, and as a two shaft high capacity shredder it keeps that flow steady even with awkward, lightweight loads. The interchangeable blade system lets you adapt the machine to different materials and renew cutting edges quickly, protecting uptime.
Why Zato double shaft shredders
Among double shaft shredders, the Blue Storm is designed for density: by reducing the size of light scrap it raises bulk density, which cuts transport costs and prepares a homogeneous feed for separation lines or a hammer mill. As established twin shaft shredder manufacturers, Zato builds the Blue Storm for continuous duty, with robust construction, low dust and noise and commissioning in about a week — no special foundations required.

FAQ
What is a light scrap shredder used for?
A light scrap shredder is used to reduce and densify thin, bulky or mixed lightweight metal — such as profiles, cables, electric motors and baled cars — so it takes up less volume and is easier to transport and separate. Zato’s Blue Storm does this with a twin-shaft, high-torque cut that keeps fines low and prepares a clean feed for downstream separation or melting.
What is the difference between a single-shaft and a double-shaft shredder for light scrap?
A single-shaft shredder pushes material against a fixed screen to produce a controlled, uniform size, while a double-shaft shredder shears between two counter-rotating shafts and excels at densifying and opening bulky light loads. For high-volume lightweight scrap, Zato typically recommends the twin-shaft Blue Storm, while the single-shaft Blue Marlin is preferred when a precise, screened output size is the priority.
How does a twin-shaft shredder increase the value of light metal scrap?
By reducing size and increasing density, a twin-shaft shredder lets more material fit into the same container, cutting transport cost per ton, and it liberates impurities so cleaner fractions can be recovered. With the Blue Storm, Zato customers obtain a denser, more homogeneous product that is better suited to separation lines and commands a better market price.
Does a light scrap shredder need special foundations?
No. Like the rest of Zato’s twin-shaft range, the Blue Storm is designed for fast commissioning on a flat surface able to support the machine’s static load, without expensive civil works. This keeps installation simple and lets the unit be integrated into an existing layout in about a week.
Can one machine handle different types of light scrap?
Yes. The Blue Storm uses an interchangeable blade system and differentiated shaft speeds so it can process a range of materials, from aluminium profiles and electrical cables to copper, electric motors and baled cars. Zato can advise on the right blade configuration and arrange a test with your own material on an installed machine.
