??? Sand very wide range of applications, applications place, mining, chemicals, building materials, cement, Sand development has been extended to water conservancy projects, this year, the water conservancy task is not yet complete, now we need to do a better job is to use the Sand, the development of our country's water conservancy task:
Water conservancy construction is bound to lead to the construction of hydropower projects, water conservancy and hydropower, and a series of construction projects is bound to lead to the increase in demand for building materials industry and large-scale construction machinery excavator, crusher, sand making equipment. Vigorously the construction of hydropower stations, demand is high-quality sand and gravel aggregate, the main equipment for the production of sand and gravel aggregate include: jaw crusher , impact crusher , cone crusher, impact crusher (sand making machine) , new sand making machine . As technology continues to mature, the development of high-speed railway construction and other major construction projects, the requirements for sand and gravel aggregate is followed to improve. Sand production process to ensure the power plant roller compacted concrete dam required a variety of graded gravel aggregate, in particular, the dust content of the finished sand, our main crusher, sand making and construction of waste disposal equipment R & D and manufacturing base in Zhengzhou Hongxing Machinery Co., Ltd. manufacturing, mining crushing machinery, mobile crushing plant , a large jaw crusher , impact crusher, sand making machine, a large cone break , high speed steel frame material production lines, hydroelectric artificial sand production line ( Sand production line), gravel production lines, R & D and manufacturing of crushing and screening equipment, and its products are widely used in mining, cement, chemicals, road, railway and other industries, especially in large-scale hydropower stations, highways, high-speed rail construction quality artificial sand stone aggregate production has accumulated a wealth of experience, the launch of the aggregate production equipment used in many national major projects. High quality sand and gravel aggregate technology, the introduction of new sand system equipment , will bring the Green Revolution of the hydropower station, high-speed railways, highways and other large projects.
Can be seen that sand production line for water engineering reliability, importance, Sand can be a short period of time make a qualitative leap of the water conservancy project, not only saving labor rate, but also greatly improve the efficiency, Henan Hongxing production of main products: jaw crusher, sand making machine, sand washing machine, belt conveyor, circular vibrating screen , vibrating feeder , sand production line and other heavy sand system equipment.
