As our national highway construction shows a strong momentum of development, good quality mining machinery and high-quality artificial sand produced by sand makers provide basic security for efficient highway building. That the number of clients who order Crushers and Raymond Mill continues to grow indicate that in some way the present development of central China is very rapid despite the influence of financial crisis, compared with the same time period in previous year. The construction of high degree highway building needs numerous sand, stones and limestone with favorable quality as the road bed. With the large-scale bridges and roads plans put into practice, the first grade raw materials such as sand, stones, limestone become more and more popular in the society. The machine produced by our company can provide you with all-around technical supports. According to specific requirements, we can combine different models together to meet various needs. HX series crusher is a high-efficiency rock crushing equipment at international leading level; the machine introduces the crushing theory and technology from hongxing Company of America and combines the actual situation of sand making. It is widely used for crushing of hard and brittle materials, such as rock, grinding material, refractory material, cement clinker, quartzite, iron ore and concrete aggregate; and it is especially suitable for the sand and sandstone making for construction and road paving. Raymond mill:http://www.hxjqchina.com/product-list_22.html ball mills:http://www.crusher-machine.com/21.html It is applied for washing applications in sand plant, mine, concrete batching plant, and industries like building materials production, transportation, chemistry, water conservancy, etc. Our sand washing machine is a highly efficient machine designed on the basis of the detailed washing needs in mining industry and comes with features like good washing effect, reasonable structure, large capacity, and less sand loss during washing process. The transmission part of this sand washing machine is isolated from water and sand, which could greatly reduce the error rate of the machine. Sand washing machinery drives the impeller in the water groove to move like a circle transmitted by electric motor and decelerator, and then mixes, overturns, cleans and discharges the sand or slag pellets in the water groove.
