With the drying up of natural sand, artificial sand has been widely used to replace natural sand in construction, highway, railway, water conservancy and other industries. Therefore, the demand for sand making machine is quite large. Under this background, we have developed and manufactured special stone sand making equipment. It can dig down most of the stones from the mountains, such as limestone, bluestone, marble and so on, and eventually the finished sand can be comparable to the natural sand in grain shape. Sand making machine is different from typical impact sand-making machine. It uses hammer head to impact stone to make sand. It is commonly called hammer sand making machine or double-rotor sand-making machine. The customer reaction of selecting this equipment on the production line of mechanical sand is also good. The advantages of this type of equipment are mainly manifested in three aspects. 1. The structure is simpler and more humanized. First of all, it i...
