With the drying up of natural sand, artificial sand has been widely used in construction, highway, railway, water conservancy and other industries to replace natural sand, so the market demand of stone sand making machine is quite large. Under this background, we have developed and manufactured special stone sand making equipment. This sand making machine can process most of the stones excavated from the mountain (especially hard outside), such as limestone, Lapis lazuli, marble and so on, and eventually the finished sand can be compared with natural sand in grain shape.
Sand-making machine is different from the typical impact sand-making machine. It uses hammer to impact stone to make sand. It is commonly known as hammer sand-making machine or double-rotor sand-making machine. Customers who choose this equipment on the production line of machine-made sand have a good reaction. The advantages of this type of equipment are mainly shown in three aspects.
1. the structure is simpler and more humanized. Mainly including the chassis, hammer head, two rotors and sieve plate, etc., the sand machine is equipped with an investigation door under the turning can be readily observed equipment processing stone condition, together with easy equipment maintenance.
2. the feed size is larger. General sand machine feed size is usually about 50 mm, and the stone sand machine can allow the size of 150 mm, or even 250 mm feed. This shows that the stone between 50mm-250mm can avoid crushing process and reduce equipment investment.
3. The hammer head of the first working part is made of high hardness and good wear resistance material, which has a long service life and reduces the economic and time cost of replacing parts and directly improves the yield of customers.
