Sand production line to meet the requirements of building sand increasing

vipeakclaire: Sand production line to meet the requirements of building sand increasing the quality of concrete aggregate with increasing demands, especially over C60 level required to meet aggregate concrete, building sand must be processed to reach the required standard. Sand production line to meet the shortage of construction sand status quo.
The past two years, the county nonmetal mining industry and non-metallic mineral products industry, the two pillars of tax revenues showed a rapid, sustained and steady growth. At present, China has basically established a non-metallic mining exploration, mining, processing, marketing, research and development work system, non-metallic mining industry has become a pillar industry in the country, but there are three non-metallic mining problems to be solved in the development.
One of the non-metallic mineral demand is growing rapidly, a sharp decline in resources, the rapid decline in the level of protection of resources. As the rapid development of the steel industry, the corresponding non-metallic minerals bring graphite, fluorite, dolomite consumption rate has increased drastically. Data show that a serious shortage of fluorite resource reserves. Rough estimate, China's annual need to spend up to two billion tons of various non-metallic mineral products.
Second Luancailanwa serious waste of resources, ecological and environmental problems outstanding. Widespread indiscriminate digging of non-metallic minerals, mining rich abandoning the poor, waste of land resources, the problem of environmental pollution.
