Demolition and concrete recycling teams always struggle with low efficiency: breaking concrete takes too long, cutting embedded rebar requires extra tools, and labor costs keep rising. An excavator pulverizer attachment solves all these problems in one go. Also known as a pulverizer attachment for excavator, it is a hydraulic excavator attachment that can crush concrete and cut steel bars at the same time. You can install it directly on your existing excavator; no need to buy additional equipment. It replaces the work of traditional breaking hammers and steel cutting tools and greatly improves demolition and recycling efficiency. If you are looking for a concrete pulverizer for sale, please contact the YG team.

Working Principle of Excavator Pulverizer Attachment
This hydraulic concrete pulverizer uses the excavator’s own hydraulic system as a power source, and completes concrete crushing and rebar separation through four core steps with its specialized jaw structure:
1. Hydraulic power transmission
The excavator hydraulic system outputs high-pressure oil to drive the oil cylinder inside the pulverizer. The cylinder uses honed tubes and imported HALLITE oil seals, which can stably maintain working pressure of 280bar to 320bar, and convert hydraulic pressure into strong mechanical extrusion force. The cylinder has a long service life and is not prone to oil leakage under long-term high-load work.
2. Concrete extrusion crushing
When the upper and lower jaws close, the serrated steel jaws made of TDNM400 wear-resistant steel apply a uniform extrusion force to the concrete block. The maximum shear force can reach 380kN to 2503kN according to different models, which can easily crush reinforced concrete of various strengths into small, uniform pieces.
3. Synchronous rebar cutting
The wear-resistant alloy steel blades installed on the edge of the jaws cut the steel bars embedded in the concrete synchronously while crushing the concrete. The blades are forged from special alloy steel, which is resistant to high temperature and deformation, and can cut rebar cleanly without burrs. You don’t need to take out the steel bars for secondary cutting, and the cut steel bars are of uniform length, which can be directly recycled.
4. Reset and prepare for the next cycle
After the crushing action is completed, the oil cylinder drives the movable jaw to open to the maximum opening height. The operator can adjust the position of the excavator to align the next piece of concrete to be crushed, and then start the next working cycle.
YG Excavator Pulverizer Attachment Features
This pulverizer attachment for excavator has many specialized advantages designed for reinforced concrete demolition work:
- High shear force, efficient crushing and separation: The maximum shear force ranges from 380kN to 2503kN, which can easily crush various reinforced concrete structures and cut steel bars of different thicknesses. The crushing efficiency is much higher than traditional manual and breaker methods.
- High-quality wear-resistant materials, long service life: The jaw body is made of TDNM400 wear-resistant steel, and the force-bearing part adopts a thickened integral plate instead of a superimposed welding process, which has higher strength. The blade is forged from wear-resistant alloy steel, which is resistant to high temperatures and deformation. The pin shaft is made of 42CrMo alloy steel, which has high strength and good toughness.
- High-quality hydraulic system, stable and reliable: The oil cylinder adopts a honed tube and an imported HALLITE oil seal, which have good sealing performance and long service life. It can stably maintain working pressure under long-term high-load operation and is not prone to oil leakage.
- Wide range of excavator compatibility: We have 5 different models, which can be matched with 6-80 ton excavators of various brands. You can choose the most suitable model according to your existing excavator tonnage.
- Easy to install and operate: You can install and disassemble it quickly on your excavator, no need for complicated modification. The operation is simple, and excavator operators can master the operating skills after short training.
How Much Steel Can You Recover From 1 Ton Of Reinforced Concrete With A Pulverizer?
For concrete recycling businesses, the amount of steel recovered per ton of concrete directly affects your profit. Many teams use traditional breaking methods, and the steel recovery rate is very low because of incomplete separation. A professional concrete pulverizer can greatly improve your steel recovery rate with its specialized jaw and blade structure.
1. Steel content in ordinary demolition concrete
According to actual construction data, the steel content of ordinary building demolition concrete is generally 30- 80 kg per ton. The steel content of high-rise building concrete and bridge concrete is higher, which can reach 80- 120 kg per ton.
If you use traditional breaking hammers and manual sorting, you can only recover about 60-70% of the steel, because a lot of small steel bars are mixed in the concrete fragments and cannot be separated manually.
2. Steel recovery rate with a specialized pulverizer
With a pulverizer designed for reinforced concrete separation, you can achieve an almost 100% steel recovery rate. The excavator pulverizer attachment crushes the concrete and cuts the steel bars at the same time, and all steel bars are completely separated from the concrete. You can directly sort and recycle the steel bars after crushing, with no need for secondary manual picking.
Taking 1 ton of ordinary building concrete with 50kg steel content as an example:
Traditional method: you can recover about 30- 35 kg of steel
Pulverizer method: you can recover about 48- 50 kg of steel
You can recover 15- 20 kg more steel per ton of concrete, which directly increases your recycling profit. For a recycling yard that processes hundreds of tons of concrete every day, this is a very considerable income increase.
3. Additional benefits of complete steel separation
In addition to increasing steel recovery, complete steel separation can also improve the quality of recycled concrete aggregate. Concrete aggregates without steel impurities can be used in more scenarios, and the selling price is also higher. An excavator pulverizer attachment can not only improve your crushing efficiency, but also directly increase your recycling income. It is a very cost-effective investment for concrete recycling businesses.
