Contrast between hydraulic breaker and hydraulic pulverizer

 

With the increasing of urban demolition projects, the requirements with environmental protection have been continuously improved. Low noise and low dust have become the necessary requirements for future construction. The traditional demolition relying on the vibration of the breaker is far from satisfying the environment requirement in future . Hydraulic pulverizer is becoming the upstart of the building demolition industry with strong crushing force . The hydraulic crusher has double powerful crushing force than the traditional hydraulic breaker, which can shorten the original demolition period by at least half.  It can help the contractor finish the project  easier and greatly saving time and operating costs.

First  Comparison of working principles

 

   Hydraulic Breaker: It is an attachment on an excavator and works on the principle of hydraulics. It applies high pressure from its small canister which has pressurized hydraulic oil stored in it. Its force is varied based on the force of piston strokes and its size.

 

   Crushing pulverizer : With oversized teeth and powerful cylinder powered by hydraulic system , the hydraulic jaws can make close and open movement  and break the concrete into small pieces .

Second comparison of Working effect

 

 

Third Comparison of Operating Cost ( In China )

 

The operating cost contrast between hydraulic pulverizer and hydraulic breaker under the same working condition.

We assume that :

1.The rent cost for a 20ton excavator is 298.5USD /PC every day . We need to rent it for 30 days .

2.Fuel consumption: engine power × coefficient 0.18 × operating time

For example ,PC200-8 ,110kwX0.18X12 hours = 237.6 litres.Diesel price :1.15USD/ Litre

 3.Working efficiency :

Hydraulic breaker VS hydraulic pulverizer =1:2  

 4.Service life :

 Hydraulic breaker 3 years VS Hydraulic pulverizer 10 years

 5.Sale Price :

Hydraulic Breaker  9000USD /Set VS Hydraulic Pulverizer  16119 /Set

6.Maintenance cost :

Hydraulic Breaker 750 USD /Year VS  Hydraulic Pulverizer  150 USD /Year

7. Extract steel bar cost

3 workers / excavator  , 60USD / worker  every day
