With the sustained and stable development of China's economy, in order to achieve the goal of green development, adhere to the principle of combining energy conservation and emission reduction, environmental protection with the development of new products and the environment, we strive to build environmentally friendly, low-carbon and energy-saving sand making machine. This Sand Maker Machine has many series,such as vsi series, vsi5x series, vsi6x series sand making machine, they are all the environmentally friendly equipment, mainly in the following five aspects:

1. Sand making machine can effectively deal with materials with high moisture content and prevent blockage. When dealing with materials with excessive moisture content, the feeding chute and backlash plate of sand-making machine can be equipped with heating device to prevent material from bonding. Sand making machine does not need bottom sieve plate to prevent blockage effectively.

2. Sand making machine can adjust the grain size of discharging material in many ways, such as adjusting the speed of rotor, adjusting the gap between backlash plate and grinding chamber, etc. Clearance adjustment can be adjusted by mechanical or hydraulic type. The hydraulic control system can be used to adjust the clearance conveniently by local operation button or distance control system.

3. The abrasion of the plate hammer of the sand machine only occurs on the side facing the material. When the rotor speed is normal, the feed will fall to the surface of the hammer (strike surface), and the back and side of the hammer will not be worn. There is little wear and tear even on the material side. And the bottom grinding rod is easy to replace. The metal utilization ratio of plate hammer in sand making machine can be as high as 45%-48%.

4. Sand making machine is suitable for both soft and very hard materials. The hammer of sand making machine is firmly fixed on the rotor by mechanical clamping structure. When it rotates with the rotor, it has a great moment of inertia. Compared with the hammer crusher (the hammer head is hanging), the rotor of the sand machine has greater momentum, adapts to crush harder materials, and consumes less energy at the same time.

5. Only 6 plate hammers are installed on the rotor of sand machine. The special tools can easily replace the plate hammers. It only takes one shift to replace a set of plate hammers. The replacement of the grinding rod in the bottom grinding chamber only takes tens of minutes, which greatly reduces the time and cost of overhaul and maintenance.

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 includes the shell, hammer head, two rotors and sieve plate, etc. There is an investigation door under the sand machine, which can open and observe the condition of the equipment processing stones at any time, so as to facilitate the maintenance of the equipment.

2. The feed size is larger. The feed size of the general sand machine is usually about 50 mm, and the stone sand machine can allow the feed size of 150 mm, or even 250 mm. This shows that the stone between 50mm and 250mm can avoid crushing process and reduce equipment investment.

3. The hammer head of the main working parts is made of high hardness and good wear resistance material. It has a long service life, which reduces the economic and time cost of replacing parts and directly improves the customer's return rate.
