River stone is natural material and a gift from nature. It is bright in color and hard in texture. In ancient times, it was mostly used for landscape decoration. With the development of science and technology, human wisdom makes these raw materials have greater application value. While maintaining the use of building decorative materials, river stone can be made into sand after a series of processing such as crushing, sand making and screening. As an important industrial mineral material, it can be used in concrete aggregates, and plays an important role in water resources and hydropower, high-grade highways, expressways, high-speed railways, bridges, airport runways and municipal engineering projects. River stone is ideal green building material with abundant resources. It takes advantages of compression resistance, wear resistance and corrosion resistance.
The market is also encouraging the application of river stone. Due to over exploitation of natural sand, river bed is damaged and ecological environment has been destroyed. The new materials must replace natural sand at this time. Of course, in order to obtain the machine-made sand replacing natural sand, it is necessary to use reliable sand making machine with reasonable process.
In the development of more than 30 years, the masterpiece of Liming Heavy Industry is river stone sand making machine. From the PCL sand making machine to the VSI sand making machine, from the 5X sand making machine with advantages of large capacity and convenient maintenance to the high-tech VSI6X sand making machine, the company continuously absorbs advanced technical concepts and combines user’s demand, finally we realize a breakthrough in the research and development of sand making machine.
