Machine-made sand is not a new thing at present, and has completely replaced natural sand in many areas. But there are still some areas that have not attracted attention. Why should the production and application of machine-made sand be developed? This is because machine-made sand has many advantages over natural sand.

First of all, the quality of machine-made sand is reliable. Because the quality of natural sand cannot be controlled, some particle gradations are difficult to meet the standard. This will not only waste cement, but also crack the concrete. The production of machine-made sand is completely controlled manually, and the particle size distribution can be adjusted during the production process. Therefore, the concrete produced with machine-made sand has a high bone-to-cement ratio, less cement consumption, and more reliable quality than natural sand.

Secondly, vigorously developing machine-made sand can protect the environment and is conducive to ecological balance. Random digging of natural sand has caused air and environmental pollution. In the process of mining and processing, about 20% of tailings will be produced, and quite a lot of tailings have not been rationally utilized, occupying land and causing environmental pollution. If these resources are turned into machine-made sand, good economic and social benefits will be obtained.

The artificial sand production line solves the problem of lack of natural sand and is also an important raw material for high-quality concrete. Machine-made sand is generally achieved through mechanical crushing, which is commonly referred to as sand making machine. We have many companies that produce sand making machines (sand making equipment), and the quality of products varies. At the same time, the quality of machine-made sand raw materials also varies. Case. Therefore, the quality of the produced machine-made sand varies greatly.

High-quality artificial sand should be blended sand-artificial sand-stone powder-mud-natural sand-weathered sand-tailings blended sand. At present, due to the considerable demand for artificial sand, some enterprises that do not have the conditions to produce inferior artificial sand with simple sand-making machinery not only pay a much higher cost than usual, but the quality of the produced concrete cannot meet the requirements and directly affect the quality of construction projects. It can be said that in addition to management and other conditions, the enterprises that produce inferior or unqualified artificial sand should highlight that the production machinery cannot meet the requirements.

Compared with natural sand, artificial sand has rough appearance and poor shape. The roughness of the appearance and the undercircle of the shape have a negative impact on the fluidity of the concrete during pouring, and will cause voids in the concrete. In this sense, the sand making machine directly affects the quality of the project. Artificial sand roughness and poor roundness are mainly caused by unqualified machine-made sand production equipment. Some sand-making equipment manufacturers with backward technology only care about their profits and produce inferior and immature equipment, which has brought serious consequences to the healthy development of the artificial sand industry. The production efficiency of the equipment produced by some enterprises is low, and the cost consumption is very alarming, and it is not mature production equipment at all.
