With China's rapid economic development, a large number of projects and infrastructure are building,which makes the building sand reduce,but this construction needs a larger number of high quality aggregates. Now the whole world is to promote energy conservation, environmental protection, and for China,considering flood control and environmental protection, we have strict limit for river sand mining and the exploitation of natural resources ,which will lead to a serious shortage of building sand.At this time,adopting mechanical making sand is one of the ways to solve the shortage of resources,and it's also one of the best ways of environmental protection. Therefore, to product and process the gravel urgently needs to research and develop new and efficient large-scale sand making machine.

View of the current Chinese energy-saving environmental protection industry, mainly in the industrial development lags behind, innovation is not strong, industry concentration is low, weak management capacity issues. Concerned that the future government will give more policy to encourage and guide private investment in energy-saving environmental protection industry, to encourage businesses to focus on energy-saving environmental protection works, outsourcing, and to promote energy management and environmental protection facilities, the contract and operation of energy-saving environmental protection professional the rapid development of service industry. For the comprehensive implementation of environment protection and energy industry development policy to promote resource-saving and environment-friendly urban development, make good urban energy-saving environmental protection industry development planning, to promote regional innovation system. For the development needs of energy-saving environmental protection industry development, and manufacturing of environmentally friendly and efficient sand making machine that is high efficiency sand making machine, the industry has recently attracted attention.

Environmental protection industry and new recycling technology equipment to give priority to ease of operation, reliable operation, energy consumption and low cost operation and management of equipment, equipment, load factor, the need forprocessing particle size, size distribution variation is an important selection factor. Sand device configuration based primarily on customer specifications, as well as stone production and use of stone to determine, Hongxing Industry the new Sand for environmental protection industry and resource recycling technology, economic and technological significantly increased, but also provides pre-sale , a comprehensive after-sales service, based on customer production site to configure the process, and strive for the customer to achieve the most rational and economic production line.
