Pebble is a kind of natural stone composed of SiO2‚ Portable Copper Ore Crusher plantit’s Mohs hardness at about 8. Precisely because of its physical property‚ processing of pebble needs special equipment. While pebble sand making machine is specially developed for hard rocks‚ which has such features as high compressive strength‚ wear resistance and less wearing parts. sand maker Pebble is widely distributed in our country‚ which has cheap price. In fact‚ the pebble sand making machine has reasonable
