What is machine-made sand? This is the first question that many people ask after hearing the word "manufactured sand". This article will introduce where machine-made sand comes from, what is the use of machine-made sand, machine-made sand and the development prospects of machine-made sand. Zhengzhou Global Heavy Industry will explain the machine-made sand in detail from four aspects including the production method of machine-made sand. I hope it will be helpful for you to understand the machine-made sand.

Where does machine-made sand come from?

   Machine-made sand, also known as artificial sand, refers to sand processed through sand making machines and other ancillary equipment. There are two main reasons why machine-made sand is increasingly entering people's attention.

What are the advantages of machine-made sand? Why is it so popular?

   1. External factors

   (1) Natural sand mining restrictions

   Due to early excessive and unstandardized mining, the natural sand resource stock has become increasingly scarce. Continuing mining is damaging the environment and neglecting sustainable development. Therefore, restrictions on natural sand mining are on the agenda. After all, orderly, planned and reasonable mining and utilization are the key to sustainable development. the basis for long-term development.

   (2) Infrastructure construction

   Since the reform and opening up, the pace of infrastructure construction in our country has never stopped. The vigorous development of infrastructure cannot be separated from the support of sufficient sand and gravel aggregates. However, in the face of restrictions on natural sand mining, the supply of sand and gravel was obviously insufficient, and a supply and demand crisis in the sand and gravel market immediately broke out.

   (3) Policy support

   It is difficult to develop only by relying on restrictions without seeking new solutions. The emergence of machine-made sand has relatively alleviated the current market situation, and a series of guidance, encouragement, support, and normative policies issued by relevant departments have provided a hotbed for its growth.

   2. Own factors

   In addition to the above external factors, the advantages of machine-made sand are the key to its popularity.

   (1) Raw materials are sufficient and easy to mine

   At present, there are at least 200 kinds of stones that can be used for sand making, such as river pebbles, granite, bluestone, and even industrial waste such as construction waste and tailings, which can be processed into recycled aggregates to play their role.

   (2) Stable output and high qualification rate

   Especially with the support of various types of sand making equipment, the output of machine-made sand is very stable, with uniform particle size, reasonable gradation, and good taste of finished products, which can fully meet the standards of construction sand.
