The advantages of cobble sand making machine
1. The structure of sand making machine is very simple and its spare parts are less.
2. The rotating speed is high and safe.
3. The sand making machine runs stable and the air discharging is uniformity. The maintenance is easy. The weight is light and the floor space is small.
4. The machine does not need lubrication for the air is not easy to be polluted. The seal effect is good with less leakage.
5. It is easy to realize the automation.
6. The performance curve of the sand making machine is stable and stable operation scope.
7. It can use heat energy. The turbine driving is more safety than the motor driving, which is helpful for speed adjustment.
The disadvantage of cobble sand making machine
1. Bad operation adaptability. The nature of gas has great influence on operation performance. In the process of starting, running and stopping, the medium changes greatly, the load also changes greatly, the driving machine should left sufficient power overmeasure. But in normal running condition, the no-load consumption is large.
2. Large speed of air floating. There is large friction on the surface, the polytropic efficiency of fixed cobble sand making machine is 0.75-0.85.
