Scrap Choppers & Side Trimmers

Scrap Choppers

The world famous Butech Bliss scrap choppers have set the industry standard for high-quality reliability, low-maintenance scrap chopping, and metal trimming machines for more than 30 years. Our vast experience with multiple patents and proven state-of-the-art features put the Butech Bliss scrap chopper in a class of its own.

Currently, we have over 400 scrap chopper units in operation worldwide. Our scrap choppers include self-threading entry chutes, fully supported knife hubs, and custom-designed exit chutes. Every scrap chopper consists of two (2) width adjustable chopper heads. Each head has a set of opposed arbors with four (4) knives per arbor.

The knives and arbors are designed to provide a helical action cut across the scrap width which requires less horsepower per cut and at a guaranteed noise level of 85 dB or less. Each knife has four (4) usable cutting edges before a knife sharpening is required. Sharpening can be done on a simple surface grinder with no special jigs.

Knife changes can be accomplished quickly with no special skills required and, with our "shimless" knife design models, the factory set knife gap is maintained after sharpening with no knife shimming required. Our scrap choppers run at line speeds of over 3,000 feet per minute. Butech Bliss Scrap Choppers process all materials, including aluminum, carbon steel, stainless steel, silicon steel and high strength alloys.


Chopper Features:

  • Each knife has four cutting edges that require only a standard surface grinder for sharpening.
  • Cuts a full range of scrap thickness without the need to adjust knife gap.
  • Self-threading entry chutes eliminate threading time and provide safe scrap handling.
  • Helical cutting action is quiet (<85db) and results in longer knife life.
  • Quick change heads option provides trimmer head replacement in less than 10 minutes.
  • Uniformly chopped scrap brings higher scrap value.
  • Many models available with patented shimless knife design - no shims required after knife sharpening.
