The world of construction and demolition waste landfill waste management more strictly, to building contractors were on site and the site of the construction waste for reprocessing. Doing so will not only reduce landfill costs, but also through the sale of a recycling of construction materials increased revenue. Because of this, many large in the rest of the world dismantling site, can often be seen mobile crushing and screening machinery in dealing with the massive construction waste and reinforced concrete, and then their recycling to a new construction. However, many of the world's removal operations in size, from a cost point of view, not suitable for use tracked or wheeled large crushing and screening machinery.

Because of the construction waste disposal regulations more stringent, and many construction projects in the planning stage will be construction waste disposal arrangements on the site. Thus, although the majority of the productive capacity of small broken machinery are not high, but the demand for them is still growing. "Dismantling and re-use of the international" magazine reported the recent development of this industry.

Europe in the recycling of construction waste and led the world regard, the average recovery is around 80 percent (in many places are much higher than this value), but still require legislative authority to further enhance the construction industry recovery.

In the United Kingdom, Food Rural Affairs, Environment (DEFRA) has recently put forward a proposal to give some measures to reduce the annual 109 million t British construction waste quantity. According to DEFRA estimates, the United Kingdom all illegal waste treatment in 1 / 3 of construction and demolition waste garbage. DEFRA is the core of the proposed site waste management plan, which describes in detail how the reduction, recycling and disposal sites on all waste generated. This program will become a legal provisions, applicable to all subject over 495,000 US dollars in building projects. The plan is to require records of the actual movement of waste, including those not in accordance with the law Treatment of the waste recycling. This requirement is to establish an audit Index, in order to reduce the phenomenon of illegal waste discarded, enhance the sense of responsibility builders. DEFRA further recommendations on the subject over 980,000 US dollars of construction projects to establish a higher level of reporting and review system.

But it is not End. According small broken machinery manufacturers DigBits the MarcusClay, said: "From 1999 onwards we began production of concrete crushing machinery, from 2004 to start producing mobile crusher machinery, in this section of a short span of time, the demolition and reuse industry underwent tremendous changes. Course, if countries and the EU should inclusion of countries, the change may be even greater. "

"Today, we learned of a British waste management with the professional terminology, that is' close 'principle, to the extent possible, in other words near the waste generated at the location of their treatment. Indeed, this terminology is not a new concept (the vocabulary stems from 1991), which has long each county was included in the British parliamentary documents, and no doubt by the European countries follow suit and strengthened. our estimation, would not allow the waste concrete and stone out of the work site of the day is just around the corner, even the small home projects - expansion of housing and interior decoration - is out. "

According to Clay, introduced, and some local authorities have already approved small-scale construction projects in China increased restrictions and allow grab by truck or truck will bring concrete waste out of the site, while also prohibits Dump Truck stop in the roadside (Fortunately, the British government has recently proposed lifting of the small construction project approval This will ease the impact of approval).

From the above we can see that on the next few years, the whole world of the ultra-small broken machinery demand to increase notably.

Fragmentation is a

Now let us look at the market with the types of small broken machinery. The most obvious is the small broken machinery should be broken with the world quite a few companies such production, of which three best-known manufacturers are from Italy, they are VTN, MeccanicaBreganzese and Eusiti.

VTN companies have two types of products. FB250-weight 2900 kg for 18 ~ 24 t of excavators, and FB350-weight 3950 kg for 24 ~ 50 t of excavators.

MeccanicaBreganzese companies can provide four types of products. BF60.1 type for 8 ~ 14 t of excavators, BF70.2 type for 14 ~ 20 t of excavators, BF90.3 type for 20 ~ 28 t of excavators, BF120.4 type for 28 t above the excavator.

Eusiti companies only EBF900VP一个models is a jaw crusher for 22 ~ 35 t of excavators. It weighs 3,400 kg, maximum production capacity of 30 m3 / h. The most famous is a crushing and screening manufacturers should be Allu Company (formerly Ideachip companies). This Finnish manufacturers are six models of SC Series products, for 8 to 25 t of excavators, they are SC2-10 ,2-15 ,2-20 ,3-10 ,3-15 and 4-05 type, which after five types of products also can be used for 5 ~ 14 t of wheel loaders. These models are broken with the weight of 8.1 kg, 915kg, 940kg, 1200kg, 1245kg and 1500 kg.

Finally, the United States R.R equipment company production Crush-all series. This series includes three products, CR75, CR95 and CR125. CR75 - is the impact of a crusher, the weight 2635 kg; CR95 - is a jaw crusher is, weight 35.9 kg, and CR125 - is the impact of a crusher, the weight 4545 kg.

Crawler Crusher

In addition to a broken with, the other ultra-small (or mini) are also broken machinery healthy development, especially in the United Kingdom. There are two companies producing micro-crawler crusher can even through standard openings. DigBits company BAVtrak jaw crusher just 750 kg in weight, can be easily used trailer transport. Its length is 1.2 m and a height of 1.5 m, a width of 0.7 m. The momentum of the current models for Mitsubishi gasoline engine, the site was very suitable for abandoned broken concrete and bricks, used in the production of rigid aggregate.

DigBits company told the "removal and reuse of the International" magazine, the company is developing some of the bigger models. Clay, said: "Development BAVtrak009 micro-breakers so that we benefited from, and the technology used in its quarries and recycling industries mature type of technology completely different."

RedRhino may be micro-breakers industry's largest manufacturers, and its 5000 Series machines in 2006 sales around the world. Not long ago, in the SED show the company also introduced three new models. Micro-machine specifications than the large number of small crusher is 50 ~ 100 t / h model, the number of many. Austria is the manufacturer of the DSB, HartlPowerscreen, KormannRockster, MFL, the MSB and RubbleMaster, Italian manufacturers have Guidetti, OM and REV, the above manufacturers in the industry are representative enterprises.

Guidetti in bauma exhibition launched Caeser3 of small broken machines. This is a 8 t crawler Systems, the largest production capacity of 80 m3 / h, the long 6.5 m, high 2 m, width 0.7 m. South Africa launched RubbleBuster manufacturers PilotCrushtec - 8.8 t, the largest production capacity of 50 t / h, a driving force for the 53 kW John Deere diesel engine. Recently, there will be a new mini-crushing machine manufacturers to join the industry. sandvik president LarsJosefsson said the company acquired mobile crushing / screening machinery manufacturers Extec and Fintec, sandvik should have the production of 50 t / h capacity above models. To achieve this, sandvik either on further acquisition of a small crusher manufacturers, or on their own development. This acquisition consolidation of the two companies certainly have to spend a certain amount of time, it appears that in the near future also do not see the small mountain sandvik brand models, but this is only "a matter of time."
