1. In response to national environmental protection requirements and raw material centralized management policies, comprehensive industrial parks have become a major trend. Mineral resource machinery development tends to be large-scale, and the degree of comprehensiveness is getting higher and higher. From the traditional single to the current diversified development, the demand for output is also increasing, and sand-making machines with large crushing ratios, high production capacity, and a high degree of automation is more and more popular among manufacturers. Large-scale, comprehensive has become the latest development direction of the mining machinery industry.

2. D&G MACHINERY sand processing equipment can improve the quality of finished products, reduce production costs, save resources, and reduce the cost and pollution of material stacking and processing through standardization, generalization, modularization, and intelligent environmental protection design. It is also easy to install and relocate and has very Significant economic and social benefits.

3. The traditional sand-making method involves natural erosion and excavation of the river bed, which is time-consuming and expensive. Sand-making machines, on the other hand, offer a faster and more economical solution by producing sand on-site, eliminating the need for transportation and reducing overall production costs.

4. The sand processing equipment is designed to produce high-quality sand with precise specifications. These machines use advanced crushing and shaping technology to ensure that the sand produced is well-graded and free of impurities. The controlled production process ensures a consistent sand quality, making it ideal for demanding applications such as concrete production and road construction.

5. Another advantage of sand processing machines is that they can produce different types of sand. These machines can be adjusted to produce sand in various grades and sizes to meet specific project requirements. Whether coarse or fine sand is required, the sand-making machine can provide the required output, providing flexibility and adaptability for various applications.

6. The sand-making machine prioritizes environmental sustainability by minimizing the exploitation of natural sand resources. As people pay more and more attention to environmental protection, the use of sand processing equipment can help reduce the ecological impact of excessive sand mining and riverbed erosion. By producing high-quality manufactured sand, these machines offer a viable alternative that helps preserve natural habitats and ecosystems.

Comparison of advantages of 2 types of sand making machine

With the depletion of natural sand resources, it is an inevitable trend that manufactured sand will replace natural sand. At the same time, the development of sand and gravel mining is becoming more and more standardized and intensive. It&#;s necessary to select reasonable sand making machine and technology to ensure sand and gravel output and quality.

1. Sand making machine (vertical shaft impact crusher)

At present, many projects at home and abroad applies the vertical shaft impact crusher as the main sand making machine, which has the advantages of high production efficiency, good sand particle shape, low operation cost, small amount of civil engineering and installation works. It also can reshape small and medium-sized stones.

The production process is "feeding--crushing--screening--returning (or warehousing)" no matter the crushing cavity is "stone striking stone" or "stone striking iron".

Generally, when the raw material is hard to break rock and has strong abrasion resistance, the sand making machine with "stone striking iron" should be selected; when the raw material is medium or fragile rock and the abrasion is medium or weak, the sand making machine with "stone crushing iron" should be selected.

Advantages: high processing capacity, low noise and low energy consumption.

Disadvantages: sand fineness modulus and stone powder content and other parameters are not easy to adjust and control.

If dry production is adopted, and raw materials are fragile, stone powder content is generally high, fineness modulus is low, if the raw materials are medium or hard to be broken, the opposite is true; the grading of final products is unreasonable, there are many coarse particles, and it is necessary to form a closed-circuit circulation production with inspection and screening.

2. Tower type sand making machine

Tower type sand machine is a new way of sand making, and it is also the development trend of manufactured sand industry in the future. In order to solve the problems of unreasonable gradation, high silt content, and substandard grain shape of the traditional manufactured sand and gravel, tower type sand making machine adopts the grinding technology and waterfall shaping technology, which makes the gradation of finished sand and stone reasonable, the particle shape round, and the specific surface area and porosity of coarse and fine aggregate can be effectively reduced; meanwhile, the dry powder removal technology is adopted to make the powder content in the finished sand adjustable and controllable.

The tower type sand making machine occupies a small area with low site requirements. The dry process production is not limited by water source and region. With fully closed structure, it is completely isolated from the outside, low noise, no emission; air screening machine is used, which is more precise than the traditional sand making equipment, and can separate qualified sand and stone powder.

The process and equipment selection of sand and gravel processing system should be reasonably planned according to the system scale and form, surrounding environment and other conditions, and meet the requirements of advanced technology, convenient construction, reliable operation, good economy, safety and environmental protection.
