"jerry-built project" has become a phenomenon people hate but can’t avoid. The reason why it happens mostly is that people maximize the benefits excessively in short time while ignoring the quality of the project.

In order to save costs, there are many builders who use sand and aggregate in construction. High quality sand and gravel costs highly in the process of mining and manufacturing, so many builders take risks to reduce the cost at the expense of quality. The fundamental measure to solve the "jerry-built project" is to save costs of gravel. ?Shanghai Shunky machinery has a producing line with large capacity and simplicity in installation and operation of complete equipment, so that can provide high-quality sand and gravel aggregate for highways, high-rise buildings, municipal, etc. At the same time, it has high processing capacity and low consumption of vulnerable part. ?After technical improvements，the sand making plant now have been greatly improved with high technology, high intelligence and complete production equipment performance. Shanghai Shunky machinery committed to produce high quality sand production equipment from the customer's interests to meet the need of each customer to the greatest extent. ?

The improvement of sand making plant not only in the quality and yield of sand, but also it reduces the cost of sand and gravel making. It makes great contribution to reduce the " jerry-built project "
