How it works
The vertical crusher takes material that has already been shredded and reduces it further, producing a tighter particle size range. A vertical rotor throws material against the chamber wall and the resulting impact and attrition breaks up composite items — motor housings, small assemblies and mixed metal-plastic scrap.
Uniform output matters twice over: separators work more accurately on a narrow size band, and denser material cuts transport and handling cost per ton. The unit is built as a stand-alone machine or as a stage inside a full line.
Horizontal crusher variants are available where the layout needs a lower profile or where material has to be fed at a different angle. Both are configured against input size, target output size and throughput.
A crusher breaks material by impact and compression inside a chamber. Rotating hammers or blades throw the feed against fixed liners until it fractures, and a screen or grate at the discharge keeps oversize pieces in the chamber for another pass. The result is a denser, more uniform product than a shredder produces, which is why crushers sit downstream of shredding in most flows.
Chamber geometry is what makes a crusher material-specific. Aluminium profiles need a chamber that grips long sections without letting them spin; motor stators need enough clearance for the steel shell to open before the winding is released; swarf needs a chamber that will not compact the chips into a mat. This is why the same drive power appears across very different machines.
Key features
- Uniform output size after primary shredding
- Suits composite scrap such as motor housings and assemblies
- Stand-alone machine or line stage
- Vertical and horizontal configurations
- Wear parts accessible without full teardown
How to choose crushers and granulators
- Match the chamber to the shape of the feed: long profiles, hollow cans, enclosed motors and loose swarf each behave differently even at the same tonnage.
- Size the drive against the hardest single piece, not the average. A chamber that is right for mixed light scrap will bog down on a solid casting.
- Check the discharge arrangement — screen aperture, grate or open discharge — against the size your buyer or next machine expects.
- Ask how the chamber is opened for clearing a blockage and how the blades or hammers are changed; this is the difference between a one-hour and a one-shift job.

Frequently asked questions
Where is the Vertical Crusher normally installed?
Typical installations: Electric motor and rotor dismantling; UBC and aluminium can densification; Mixed metal-plastic composite scrap. Siting is decided by the feed arrangement and the space needed around the machine for maintenance access.
How do I get a price for the Vertical Crusher?
There is no list price — every unit is configured to the material first, because the drive, chamber or coil changes with it. Send the material you process, the throughput you need per hour and the destination port, and the quotation is built on those three.
What is the difference between a crusher and a shredder?
A shredder tears material apart and tolerates mixed, bulky feed. A crusher breaks it by impact against fixed liners inside a chamber and holds it there until it is small enough to pass a screen, so the output is denser and more uniform. In a recycling line the shredder normally comes first and the crusher second.
Can one crusher handle several different materials?
It can, within limits. The chamber geometry that grips aluminium profiles is not the one that releases a motor winding cleanly, so a machine configured for one feed stream is usually kept on it. Where a plant switches materials regularly, the practical answer is a chamber with interchangeable screens and a rotor that can be re-bladed.
How is a crusher kept from jamming?
Three things do the work: a chamber shape that keeps material moving instead of spinning in place, a drive with enough torque to push through a slug instead of stalling, and a control system that reverses the rotor when it detects an overload. Manual clearing should be the exception, not the routine.
