Yifan Construction Waste Recycling Program
In order to develop new markets and spread building waste treatment technology over
the country popularization of impact crusher mining machinery manufacturers as soon as possible, Zhengzhou YIFAN Machinery Co., Ltd. based on market demand and combined with the most advanced production technology, research and development various mobile crushing plants for construction waste crushing.At present we have already product two type construction wast crushing plants: mobile crusher station and stationary crushing station. The
Mobile Crushing Plant include jaw mobile crusher station, impact mobile crusher station, cone type mobile crusher station, combined mobile crusher station and mobile screening station. Construction waste, industrial waste, cinder, coal, rock, slag, fly ash, building materials, non-metallic solid waste and other waste,according to solid waste application process can be produced of various types of new building materials to meet the quality test specification.By the different device configuration,effective utilization of construction waste can reach 80-100%.Because of the no secondary pollution,our device can achieve ideal environmental effects,near-zero pollution and emissions.jaw crusher: http://www.jawcrushers.org

A quarry is a big man-made hole in the ground from where minerals or rock are taken out. Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth's surface. Quarrying is a type of mining and is also called as open pit mining or strip mining. When minerals are found profound beneath the surface, a deep mine has to be dug to dig out them. Quarries are normally dug deeper and bigger; awaiting the mineral resource is worn out. When they are no longer used, quarries are frequently utilized as landfill sites for the disposal of waste.
Quarry-related Problems
Quarries in level areas frequently have particular engineering problems for drainage. The Coquina Quarry is excavated to more than 60 feet (18 m) beneath sea level. To lessen surface leakage, a moat lined with clay was constructed round the complete quarry. Ground water that leaks into the pit is pumped up into the moat. Many quarries fill with water after desertion and turn into lakes. Further quarries are made into landfills.
A further problem is the pollution of the road from trucks when they are leaving the quarries. To control and eliminate the pollution of public roads wheel washing systems are becoming more common.
Quarry Management and Equipment
Quarry management varies from case to case the optimal proceeding method. The main quarrying methods are drilling and diamond wire cutting. In many cases also chain cutting is used but only for marble or travertine.
Generally speaking, quarry equipment includes the following machinery: pneumatic steel drillers (for vertical, horizontal or inclined drilling, manual or mounted on special devices), mostly diameter 34 mm, pneumatic down-the-hole hammer drillers (for making vertical holes for introducing the diamond wire), mostly in diameter 85-90 mm, diamond wire machines (for large primary cuts), smaller diamond wire machines (for secondary cuts), etc.Mobile Jaw Crusher Plant: http://www.mobilecrushingstation.com/Mobile-Jaw-Crusher.html

Selection of Quarry Machines
Different quarrying machines have different functions which have to be evaluated according to the following factors:
1. Type of rocks (hard, soft, abrasive, etc.)
2. Specific configuration of the quarry
3. Quarry yield or recovery (normally between 25 and 50%)
4. Value of the material
5. Requested production speed
6. Specific tool costs
7. Machine depreciation
8. Labor cost
9. Others
YIFAN construction waste recycling program:
1. The abandoned buildings of concrete and brick waste, can be used for making coarse and fine aggregate which is raw material of high strength grade concrete, mortar or preparation of blocks, wall panels, floor tiles and other building material products.By adding curing material into coarse and fine aggregate,it also can be used for road pavement base.
2. Use of waste tile to produce aggregate, can be used in recycled bricks, blocks, wall panels, floor tiles and other building material products.
3. the muck can be used for road construction, pile filler and foundation.
4. Abandoned timber and no-obviously damaged timber can be directly re-used for reconstruction buildings,and seriously damaged wooden may be used as the raw material of wood recycled sheet or paper.
5. According to the appropriate proportion,abandoned road asphalt mixes can be directly used of recycled asphalt concrete.
6. Abandoned road concrete can be processed into recycled aggregate and recycled concrete.
7. Scrap steel, scrap steel bars and other metal scrap material are directly used for recycled processing.
8. Such glass,plastic,ceramics waste can be used as the difference case also.
