Sand making machine occupy the market of hard rock sand and gravel aggregate

At present,using sand making machine to produce mechanical sand is a major production sources of China's construction industry aggregates. With the development of the construction industry in recent years, the various parts of the country have started to gradually shift from the exploitation of natural sand to build sand production line to produce mechanical sand.

                                                                                                                     

 

The main raw material for sand making process are: granite, basalt, river gravel, pebbles, tailings, slag, iron slag, etc. They are all hard ore.In crushing process,this will bring severe wear for sand and gravel crushing plant. The gravel manufacturers need to spend a lot of money to replace parts and routine maintenance to ensure the normal operation of the entire production line.
