Swarf Crusher KB20
Powerful, Quiet, and Extremely Reliable – Engineered for High-Capacity Volume Reduction of Metal Swarf
The KB20 metal swarf & chip crusher is a high-performance solution designed for higher chip flows in centralized chip handling systems. This robust crusher utilizes low-speed operation to break down long and bushy metal swarf into shorter fragments, making them ideal for centrifuging, briquetting, or further processing. Thanks to an integrated hydraulic tramp metal discharge, solid objects pass through automatically without causing downtime or requiring manual clearing, ensuring exceptional reliability during continuous industrial operation. Swedish-manufactured quality with minimal energy consumption and a noise level below 70 dB(A).
Key Applications
- Large-scale crushing of long and bushy steel chips and swarf
- Volume reduction in centralized chip and fluid handling systems
- Pre-treatment of chips prior to high-capacity centrifuging or briquetting
- Integration into both stand-alone and central chip handling solutions
Benefits
- Very low energy consumption and minimal wear due to low-speed crushing
- Effectively handles large chip nests and varying materials without disruptions
- Hydraulic tramp metal discharge – solid objects pass through safely without damage
- Stable and compact design for easy integration into existing production lines
- Extremely quiet operation (<70 dB(A)) for a better working environment
- Manufactured in Sweden – built for the most demanding industrial applications
System Integration
The KB20 can be installed as a standalone crusher or integrated into complete chip handling systems together with conveyors, centrifuges, briquetting equipment and fluid separation. The consistent chip size that the KB20 produces creates stable flow and high reliability in subsequent process steps.

Design
The KB20 is a powerful and low-speed chip crusher with high capacity and a robust design intended for continuous industrial operation. The machine has a spacious conical feed hopper with rotating feed arm that efficiently pulls down bushy and tangled chips to the crushing head, where the material is ground into short chip fragments of uniform size.
A central part of the design is the hydraulic bar end ejection system. Through split tools and automatic reversing, solid objects – such as bar ends and bolts – can pass through the crusher without causing downtime or damage. This provides very high operational reliability, low maintenance and stable function even with large chip nests and varying materials.
Operation
The chips are fed into the hopper and caught by the feed arm, which provides a steady flow into the crushing zone. At the bottom, the crushing head works against the stationary ring and breaks down the material into short chip fragments. The finished fragments then fall directly out through the outlet for further handling, such as centrifuging, briquetting or transport.
The machine continuously monitors its load and automatically reverses with an open bar end ejection if a solid object enters the crusher. In this way, the part can pass without manual cleaning, which ensures stable operation and very low maintenance requirements.
Accessories & Options
- Upper receiving hopper – design, volume and connections according to feeding system
- Stand or mounting if special positioning in system is required
- Level guard in hopper for feed control (optional)
With these options, the KB20 can be integrated effectively into both simple and more advanced chip systems without changing the machine's function or capacity.
