Sand Maker Gives powerful Support to National Highway Construction

timeMar 29,2012

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 effificient 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. As a result, the related sand making plant and grinding machines are in urgent need. The construction of a high degree highway will promote the development of industrial belt on both sides of the road as well as the promotion of other industries. As important infrastructure supporting the national economy, highway construction can not only improve the investment environment but also help change people’s way of thinking so as to make the economy and society of central China opener. Take Jiangxi Province as an example. Jiangxi Province takes 23 years to break a 5 billion dollars record of foreign investment. Entering the new century, the total foreign investment increases from 5 billion to 10 billion within only 3 years, and it takes less than 4 years to grow from 10 billion to 20 billion. Jiangxi Province always goes in the front rank introducing foreign funds for many years in a row, which makes historic breakthrough. Here, we can see the return of infrastructure construction. In terms of a growing cry for central upraise, the six central provinces all give priority to the improvement of transportation condition. Investment in highway construction continues to grow so that the highway building changes with each passing day. The highway now spreads all over the central plain and develops as a network with the transporting distance increasing rapidly.

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 Barmag 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.
Working Principle Stone less than 50mm enters sand making machine through conveyor belt. Stone is crushed by hitting other stones. Material falls down to impellor cavity. Under great centrifugal force, it hits material that coming downwards. After hitting each other, they force a vortex between impellor and shell, and hit each other several times. Finally, smaller stone comes out and goes to vibrating screen. Satisfactory material is transported to sand washing machine. Overlarge material will go back to sand maker to be crushed again. Output sizes can be made according to customers’ requirement. If input size is larger than the designed size, other crushing equipment will be necessary. 

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.
1. It is of simple structure. The bearing device of impeller drive is separated from water and materials with water, to avoid in a large degree that the bearings are damaged by being soaked with water, sand or some polluted things.
2. When it is used for cleaning sand in quarries, it has many advantages compared with the traditional spiral one.
3.There is little loss for medium-sized and fine sand and stone powder. The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction.
4. There are no other wearing parts except the screen mesh.5.It features long service life and few times for maintenance
