The application of sand making machine in high-speed rail construction

Release date : 2014-06-22      Source : Hongji Group

The sand making machine has enter the application in the high-speed rail construction, and the demand of the sand making machine continue rise.

As the railway ministry reported that: the whole railroad construction mileage of our country will increase from the current 91000 kilometers to 120000 kilometers during the "1025", the total investment of China railway construction will reach 2.8 trillion yuan, the vestment in new line will grow 87.5% and the total investment will grow 41.4%. The quick railway will reach 45000 km and the railroad construction mileage of Western will reach 50000 km, and the repetition rate and the electrified rate will respectively reach 50% and 60% , which open the new era of China's high -speed rail. At the same time,the need of crusher, sand making machine, sand making production line and other high-speed rail aggregate device come to the situation of demand exceeds supply.

The investment of the railway construction directly stimulate the developing of engineering machinery and mining machinery, the sand making machine in mining machinery has been increasing in demand. High-speed rail construction is relatively strict with the quality of the sand or stone aggregate, so improving the product quality of the aggregate and enhance the productive technology is the main task persistent by Henan Hongji mine machinery Co.,Ltd all the time. PL vertical impact crusher is one of the most widely used sand making machine and it is a kind of crusher crushing materials by the impact between the material and the material or between the material and metal. PL vertical impact crusher was through the national identification of new products in 1991 and was rated as the state-level new product in 1992. PL vertical impact crusher has the characteristics: with unique rotor structure design, materials technology, breaking speed optimization and the perfect combination of the hydraulic design. It is the model of the perfect combination of the specialized fine crushing technology and mechanical equipment and is the fully reflect of new technology.
