Artificial sand processing technology has entered a long exploration stage since long years ago in the world. But this technology and equipment developed very late and slow in research and development in China, for some large water conservancy construction project in the use of artificial sand, the sand making machine is mainly introduced from abroad. There are still certain gap between domestic sand making equipment and foreign advanced level. But we believe after a long time of hard work, we can catch up with or surpass the foreign advanced level. As the high level of highway has been frequently built in recent years, the requirement for asphalt and aggregate is more, and a large number of crusher equipment have been used.

Chinese highway construction develops soon, and the gravel production also has got great development and improvement. The stone quality the highway needs should meet the two aspects: one is the resource’s characteristics, namely, durability and chemical stability; the other is processing characteristics, including a 0.075 mm particle content, etc. Needle flake stone is related to the physical properties of the stone itself and the selected processing machinery, production process and so on. Generally, hard and brittle rock is easily made into needle flake when they are broken. Predominantly the stone needle flake content produced by extrusion crusher is higher, such as jaw crusher.

While impact crusher, vertical shaft impact crusher, etc. produce relatively small stone needle flake by impact method and breaking rock. Henan Hongxing developed a new generation of vertical shaft impact crusher, namely, PF series impact crusher, integrating three kinds of crushing modes, which has become the core equipment of mechanism sand industry: according to different stone and different application, by changing the crushing cavity’s feeding way and core structure it can not only guarantee the standard of gravel grain shape but also increase production on the maximum limit, and reduce running cost. The new generation of vertical shaft impact crusher has achieved the function transmission at any time on the premise that you do not need to expand the investment into the equipment.
