With the increasing population of China, housing pressure is growing, the need for more housing to live, but it requires sand and stone, natural sand can not meet the needs of the market, the need for more artificial sand to dominate Market demand.

 River pebbles and basalt at the same time a high hardness of the rock, roughly in the Mohs hardness of 5.6-6.0, hardness, it indicates that the sanding equipment for the wear and tear will be large. So we usually use multi-section broken method to solve this problem, the spring cone crusher in the hard rock broken has a great advantage, spring insurance strength, crushing force is also large, high production efficiency, for some of the relatively small river pebbles , If the Sand Making Machine meet the feed size, you can directly to the spring cone crusher as a head breaking equipment, save the jaw broken operation of the stage, reducing the investment. But for some large river pebbles or basalt stone, we recommend using three or four broken mode, the front jaw crusher, then the spring cone crusher, then need more vibrating sieve, and finally more efficient sand making machine .

  Spring cone crusher cost is relatively low than the hydraulic cone crusher, the production efficiency is not low, but there is no hydraulic maintenance on the convenience of the demolition of the spring is more trouble, but the hard rock to overcome the ability to be higher than the hydraulic cone crusher.
