In recent years, the pace of cement enterprises entering the sand and gravel aggregate market is getting faster and faster and large cement groups have already taken the lead. By actively extending the enterprise value chain, these large groups continuously develop a growth chain that integrates cement, sand and gravel aggregate, and concrete. Cement companies are rapidly expanding in the field of sand and gravel aggregates, and what are the reasons behind this?
For a long time, overcapacity has been a bottleneck that held back the healthy development of the cement industry. Under the premise that cement capacity only decreases, cement enterprises will open up new channels and increase new economic growth points, while investing in sand and gravel aggregates happens to be advantageous at the right time and place.
The construction of new infrastructure, new urbanization, transportation, water conservancy and other major projects is expected to drive the huge demand for sand and gravel aggregates in the market. The increase in demand will help drive the price of sand and gravel aggregates to rise simultaneously.
The gross profit margin of listed cement companies and their subsidiaries is mostly more than 50%, and several listed companies' aggregate business gross profit margin exceeds 70%, which is astonishing!
Cement enterprises have unique advantages in entering the sand and gravel aggregate market, such as utilization of low-grade ores, extending the industrial chain, reducing the role of waste rock yards, and reducing secondary environmental disasters.
Cement and sand and gravel aggregates both belong to mining industry. For cement enterprises, on the one hand, they can use cement mine waste to produce sand and gravel aggregates, which has obvious resource advantages; On the other hand, if cement enterprise wants to apply for a sand and gravel mine specifically for the production of high-quality aggregates, it has unparalleled advantages in mining procedures, investment production, financial strength, and other aspects.
Cement enterprises make long-term piled low-grade ore into sand and gravel aggregates, which can not only turn "waste" into treasure and reap economic profits, but also receive strong support from the national.
Currently, there are multiple channels for cement enterprises to enter the field of sand and gravel aggregates. There are two common methods: use the waste stone stripped from their own cement mines to produce sand and gravel aggregates, or to invest in specialized sand and gravel mines to produce sand and gravel aggregates.
While using waste stones stripped from cement mines to produce sand and gravel aggregates, the main raw material for cement production is limestone. The limestone waste stones stripped during the mining process are used to produce sand and gravel aggregates, and the finished aggregates have good performance when used as road foundation stones and building aggregates.
With the further increase in demand for sand and gravel aggregates, more and more cement enterprises are starting to layout new businesses and invest in specialized sand and gravel mines to produce sand and gravel aggregates. From the market situation in recent years, this choice has been proven to be correct in practice.
It needs to be emphasized that, whether using the waste rock stripped from its own cement mine to produce sand and gravel aggregate or investing in a specialized sand and gravel mine to produce sand and stone aggregate, enterprises must pay attention to closing the pit when investing in order to avoid losses.
For enterprises that use their own cement mines to produce sand and gravel aggregates, pay attention to avoid inferior use of high quality aggregates. Generally speaking, the quality of limestone used for cement production is higher than that of limestone used for sand and gravel aggregates production.
In fact, for cement mining enterprises want to enter the sand and gravel aggregate market, they can fully utilize mining waste to produce sand and gravel aggregates which not only can turn waste into treasure and increase new economic growth points, but also benefits environmental protection and achieves harmonious development between humans and nature.
Each country has certain standards and regulations for the general requirements and technical indicators of sand and gravel aggregates.
The technical indicators mainly include particle grading composition, mud content/stone powder content and mud lump content, flat and elongated particle content, harmful substance content, solidness, compressive strength and crushing value indicators, apparent density/loose bulk density/porosity, water absorption, water content/saturated surface dry water absorption, etc.
Only sand and gravel aggregates with quality meeting the standard requirements can meet the needs of the concrete industry.
Cement production also needs crushing process, but its crushing requirements and standards are fundamentally different from the aggregate crushing process.
Firstly, the cement crushing process aims to generate cracks in the stone material, facilitate subsequent grinding process, and improve grinding efficiency. However, these cracks are indeed fatal to aggregates, which can seriously affect its solidness, crushing value, and other indicators.
Secondly, there are clear requirements for sand and gravel aggregates in terms of particle size, grading, stone powder content, and mud content. If the construction of sand and gravel aggregate production lines is not reasonable, it will not only lead to a decrease in aggregate quality, but also reduce investment returns.
Therefore, when constructing a sand and gravel aggregate production line, cement enterprises must conduct preliminary research and familiarize with the production process and operation mode of sand and gravel aggregates to avoid irreparable losses.
In a favorable environment of the sand and gravel market, some unreasonable factors are often ignored, but when the sand and gravel price returns to a reasonable range, we should pay more attention to the quality of aggregates.
From "price" to "comparison of comprehensive strength", the sand and gravel industry will inevitably undergo a huge transformation. This transformation tests whether the supply side of aggregate enterprises can respond to high-quality demand timely. Therefore, enterprises that take the lead in high-quality development are expected to become the main force and winners of the aggregate market in the future.
So, what are the key aspects for the high-quality development of sand and gravel aggregates?
For cement enterprises, they should not only increase the importance of sand and gravel aggregate production, but also choose more suitable equipment.
When investing in sand and gravel aggregates, cement enterprises can focus on equipment that adopts the "crushing" principle, such as cone crushers. It should be emphasized that the production of high-quality machine-made sand is more difficult and requires higher requirements than aggregates, and strict proportions are required for particle size and grading. If cement enterprises have sand production needs, high-quality and durable vertical shaft impact crusher or tower-like sand production systems are essential.
