We can apply the slogan from Nong Fu Spring to explain the feature of natural sand We do not produce sand, we only bring them from the nature. Generally speaking, natural sands can be directly used which are transporting from the source region of river or lake to work site and concrete plant without any processing. With the exhaustion of natural sands in recent years, many provience have already issued the policy for prohibition of natural sand mining in order to protect the environment. Obviously, natural sands can not meet the demands for the construction market. The emergence of mechanism is the inevitable trend of market development, and also the revolution of construction sands and aggregates material.
1. It prompts the fundamental change of the parodution mode, where the aggregates manufacture change into the industrial prodution mode.
2. It changes the product character. Mechanism sand is produced by processing raw material according to the specific requirements such as grain size, grading, podwer content, silt content, etc. That is to say, we can produce qualified products according to our will instead of relying on the nature.
3. It optimizes the effect on environment. The traditional sand making way has negative effect on the environment, and serious damage on the riverway. While the mechanism sand made by the sand making machine can process various kinds of waste materials and tailings into qualified aggregates. In this way, it's not only realize the sustainable recycling utilization of resource, but also reduce the damage on environment.
