Pulverizers

The Nye CP4 high-speed concrete pulverizer is all about speed, power and productivity.

A good pulverizer has to be virtually indestructible. Proper heavy-wall tubular bridges and a QT100 alloy steel frame give Nye CP4 series pulverizers the right combination of brute strength and toughness for extreme cold weather pulverizing. Strategic use of AR400 and 500 steels gives the abrasion resistance needed for years of high speed processing in the hardest reinforced concrete.

All Nye CP4 series pulverizers feature replaceable high strength AR500 alloy teeth that are welded-in so they won’t fall out and jam crushers and down-stream equipment. Our unique biomimetic tooth profile mimics bone crushing teeth found in nature with retro curved cusps that hold material in, penetrate better and stay sharp longer than simple triangular teeth. Longer “cracking” teeth in the center concentrate initial pressure on larger chunks while the secondary teeth pulverize the material into manageable pieces. The open tooth flow-through design promotes rapid throughput and prevents material impaction.

An optional heavy-duty 4 position ripper shank allows the operator to rip, flip, pry, and sort materials. The patented ripper has a replaceable tooth and is especially suited for prying down between expansion joints and flipping large concrete slabs.

The CP4's serrated pinch plates provide the grip needed for pulling and sorting rebar and wire. The nose and heel plates are made of AR400 hard wearing steel, with weld-on cutting edges for scraping, lifting and flipping concrete slabs, walls, bridge decks and asphalt.

A sturdy tubular core runs the full width of the CP4 on both the upper and lower jaws preventing twisting and flexing. The torque tube’s heavy-wall circular profile withstands torsional loads involved in serious concrete demolition better than cheap fabricated or flat-plate type bridges.

Nye CP4 pulverizers are offered in 3 basic mounting configurations: Direct Pin-On, Dedicated Quick Coupler, and Pin-Grabber compatible. The operator can fine tune production by adjusting the angle of the lower jaw using the three position support bracket or an optional hydraulic cylinder.

All Nye CP4 series pulverizers are built to order, one at a time, with a mounting pin group made specifically for the excavator. You get a dedicated tool that fits properly, and has the latest design advancements built-in.

This is the best there is! - The CP4 pulverizer is mature and highly refined, it’s the most durable and longest lasting pulverizer for demolishing concrete on demanding jobsites where downtime due to equipment failure cannot be tolerated.
