2. The artificial sand making and stone reshaping in the engineering field of water conservancy and hydropower, high-grade road, expressway, high speed railway, passenger transport line, bridge, air strip, municipal works, high-rise buildings.

The structure of sand making machine: it consists of feeding hopper, distributor, crushing chamber, impeller, spindle assembly, base plate, transmission part and motor.

Characters of VSI sand maker:
VSI sand maker is the newly designed equipment by authoritative experts on the basis of the working conditions of China. VSI sand maker is the present domestic exclusive production device at world's advanced level with high performance. Its design adopts unique rotor structure, wear-resisting material technology, optimized broken speed and the perfect hydraulic combination. It is a successful example of perfect combination of the specialized technology and finely machinery manufacturing, which also reflects the new technology and the new craft.

VSI sand maker provides high quality sand aggregate for expressway, high speed railway, high-rise building, municipal works, and the construction of hydroelectric dams. It is the first choice  for artificial sand making and the stone reshaping.

 Sand making machine is a high-efficiency rock crushing equipment with home and international leading level; the machine is developed by introducing the crushing theory and technology from Barmag Company of America and combining the actual situation of sand making.

Artificial sand maker production line

The stone materials are crushed preliminarily in the jaw crusher. Secondly, the crushed rough stone materials are transported into the impact crusher for further crushing by the belt conveyor. Thirdly, the stone materials are separated into two parts by the vibrating screen. The part whose size is suitable for the sand making machine will be transported into the sand making machine and the other part will be transported into the impact crusher. Some of the former part of the stones which are crushed in the sand making machine will turn into required sand and be washed by the sand washing machine (selectable), and the rest stone materials will be transported into the impact crusher to be crushed once more.
Artificial sand washer production line has features of high automation, low operating costs, high crushing ratio, low energy consumption, large output, easy maintenance, uniform granularity and good shape of the products, reasonable gradation and the produced sand conforms to the national standard of construction sand.

Characteristic feature of Hongxing sand making machine

1. High capacity, high productivity--50-500t/h, the output is 30% higher than that of the traditional sand maker under the same power.

2. Low consumption of wearable parts--- best design of crushing chamber to make it have little friction with the wearable parts, 30% lower running cost compared with traditional equipments, reducing the cost directly.

3. Excellent shape of final products--- cubic products shape, good granularity, reasonable grading, adjustable fineness modulus, especially suitable for artificial sand making and stone reshaping. The practice has shown that the effect of this series sand maker can improve 30% output in the process of sand making and stone reshaping than the traditional equipment.

4. Easy installation and maintenance --- light weight, various installation ways, movable installation; the installation, repair and maintenance are easy, the operation is easy. 

Materials are transferred to sand making machinery from hopper and then they fall into two parts by material-scattering device. One part falls to the impeller which rotates at a high speed from material-scattering device. In the impeller, materials rotate at even higher speed and their acceleration is as big as hundreds of acceleration of gravity, then they are thrown out through three passages of impeller at a speed of 60-70 meters/second. They firstly hit part of materials that fall from material-scattering device, then strike with materials inside the cavity and its direction of motion changes to downward. The closed circuit forms. Usually, the materials can be crushed to the ones that are smaller than the mesh after three times in the circulation. The crushed materials will be discharged from outlet. 

• 1. It is suitable for fine crushing and coarse grinding
• 2. It is suitable for crushing mid-hardness and extra hard materials ( corundum, agglomeration aluminium, etc.)
• 3. Simple structure and low cost
• 4. Impeller and material layer in the crushing cavity can prolong service lifetime of easy-worn parts and avoid maintenance;
• 5. Light weight and various ways of installation and portable installation, etc.
