Material Processors

Concrete Pulverizers | Demolition Shears | Concrete Crackers


NPK's Material Processors are an efficient solution for concrete, steel and rebar processing; building and bridge demolition; and recycling.

Maximum productivity
Interchangeable jaws provide superior results in demolition, concrete processing and scrap recycling.

Cost effective
Far more economical than buying three different demolition attachments for three different applications.

Rugged design for extended life
Manufactured from high-strength, abrasion-resistant steel; reinforced shield protects cylinder rods.

Full 360° power rotation
Provides an effective angle of attack for any job, wherever the location.

Reduced transportation costs
On-the-job processing reduces material volume, which cuts down the number of trips required to haul material away.

The NPK advantage in parts and service
Over 280 NPK distributor outlets are professionally staffed and conveniently located to serve your needs. Just one of the many reasons that have made NPK the leader in excavator-mounted hydraulic attachments.

Cylinder design improves crushing/piercing power to handle the toughest jobs
Exclusive integral hydraulic intensifier system boosts power by reducing cycle time, while improving productivity and providing greater power-to-weight ratio.

NPK dedicated mounting kits enable material processors to be mounted as excavator attachments for carriers within the recommended weight range for each model. See the Attachment Wizard to determine which NPK hydraulic attachments are compatible with your carrier.

Potential applications include:

  • C&D recycling / sorting
  • Concrete recycling
  • Commercial demolition
  • Separating concrete from rebar
  • Concrete cracking
  • Cutting rebar, pipe, steel, and other scrap metal
