Concrete Crushers

Concrete Crushers | Concrete Pulverizers

NPK's Primary/Secondary Concrete Crushers are designed to effectively handle any primary and/or secondary demolition and recycling operation.

NPK concrete crushers easily cut through reinforced concrete and light steel structures allowing material to be separated and recycled, and simultaneously, permits easier handling of material.

Faster, more efficient separation of concrete and steel rebar
Powerful concrete crusher forces increase when jaws meet resistance, as the exclusive NPK cylinder intensifier converts flow to pressure.

Designed for performance
With the newly improved tooth configuration utilizing a high-profile center tooth and lower profile teeth on both sides of the moveable jaw, these concrete crushers can be used for both primary and secondary crushing operations. Abrasion resistant, high strength, alloy steel teeth allow decreased wear and increased durability. In addition, the "R" models come with full 360 degree power rotation for maximum versatility.

Maximum crushing/cutting force with more efficiency
Competitive cylinder systems need larger cylinders to equal the force developed by the more compact NPK intensifier system. On the job, NPK's exclusive integral hydraulic intensifier system provides faster cycle times compared to competitive units using larger cylinders that require considerable amounts of flow to produce an equal amount of productivity; thus producing the shortest cycle time in the industry. Cutting-torch operations are eliminated by a replaceable high-strength, steel center, cutter that slices through rebar and light steel structures.
