Crusher application field is very broad, in terms of construction waste crushing, the concrete crushers for hire, old cement concrete slab is building in the production of waste and old cement concrete slab grinding technology is through the special facilities for the old cement concrete pavement cracked, crushing, thus reduce the effective area of plate, fully release of internal stress, reduce vehicle load because of temperature, humidity and displacement of the combination of plates, to solve the reflection crack diseases such as damage to add layer. Old cement concrete slab grinding processing technology has many advantages, can shorten the construction period, optimize the structure of pavement, saving investment, and makes possible the in situ regeneration of resources utilization, at the same time of reducing waste disposal, and to protect the ecological environment, resources and environment sustainable development, it is very obvious environmental benefit, economic benefit and social benefit, it also can make the crusher toward the direction of energy conservation and environmental protection, can also create a low carbon economy to make due contributions.
When broken old cement concrete slab, the development of SBM Used Portable Concrete Crusher is very strict, mostly using polygon impact crushing technology impact crushing impact roller, change the traditional light round steel wheel roller to polygon, working principle is to use steel wheel wheel surface and the surface resistance effect, make the wheel and axle rise and fall repeatedly, so that the steel wheel have impact on the road. At present there are two kinds of commonly used impact roller, it can be seen that the trilateral impact roller has a much higher energy than the pentagon, for cement concrete pavement plate, the floor slab rupture pressure stability, the base supplement on the compaction is only an auxiliary role, if the trilateral form for stamping, energy is too large, will make cement concrete slab too shattered, used as a base. So in the innovation of old cement concrete pavement, the pentagon impact roller is generally adopted. Impact roller can produce a lot of shock wave, the effect can achieve 5 m depth, effective depth at about 2 m. Currently, the facility is mainly used for Gao Tiantu embankment compaction at home, application results show that the reduce the sedimentation of roadbed, increasing the overall strength and reinforcing the soft and weak subgrade foundation has performed better than the conventional rolling. The application of this technology in the aspect of subgrade compaction is more, but in the old cement concrete pavement on stamping pieces of an engineering example is not much, so realize the energy conservation and environmental protection of broken is overwhelming, welcome you to visit our energy-saving crusher, we produced crusher energy-efficient, well received by users.
Crusher crushing technology is a new technology of the old cement concrete pavement renovation. Innovation of old cement concrete pavement, of the old pavement plate by crushing technology, after can be directly used as pavement base, the paving layer does not produce serious reflection cracking, has the good economic and social benefits. Cement concrete pavement has been used in our country, and develop quickly, the old cement concrete slab grinding technology has very broad application prospect in our country, hand in hand together to build energy saving low carbon crusher crusher environment.
