NPK X-7AFR

New NPK X-7AFR Concrete Crusher for Sale

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

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

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.

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

Improved design for easier maintenance: In addition to the bolt-on replaceable tooth plate on the movable jaw, all “A” models now utilize a bolt-on replaceable plate on the corresponding portion of the fixed jaw.  The new design decreases downtime due to repairs while increasing the life of the crusher.  Cutting-torch operations are eliminated by a replaceable high-strength, steel center cutter that slices through rebar and light steel structures.

• Mechanical/Free: “AFR” Models: Equipped with a free mechanical style rotation bearing with heavy duty spring-loaded stops.  The free rotation bearing allows the crusher to self-position on material and rotate throughout the bite, eliminating twist on the machine arm.
• Full Hydraulic: “AR” Models: Equipped with a full hydraulic rotation system which requires a secondary hydraulic circuit.
• Electro-Hydraulic: “AREH” Models: Equipped with an electro-hydraulic selector valve allowing operation for both jaw and rotation off of a single auxiliary circuit and 12V power connection.
