Iron ore is a key raw material for steel production. However, a large amount of waste rock is often produced during mining and processing, resulting in resource waste and environmental pollution. So, can iron ore waste rock be converted into machine-made sand? The answer is yes. This article will give you a detailed analysis of the sand-making potential and application prospects of iron ore waste rock.

Consulting iron ore waste rock crushing and sand-making equipment

1. Feasibility of sand-making of iron ore waste rock

Iron ore waste rock can not only alleviate the market demand pressure for sand and gravel, but also effectively improve resource utilization and reduce environmental pollution. Through reasonable treatment, iron ore waste rock can be used to prepare machine-made sand that meets construction standards. The particle size can be controlled between 0-5mm, with high quality and few impurities, which is suitable for concrete and road construction.

Processing requirements:

The internal and external impurity contents of iron ore shall not exceed 5% and 15% respectively.

Select appropriate sand-making equipment to ensure efficient production.

2. Sand-making process and equipment configuration

The sand-making process of iron ore waste rock includes multiple steps:

Jaw crusher: Perform preliminary coarse crushing to ensure uniform feeding and improve production efficiency.

Cone crusher: In the middle crushing stage, the lamination crushing principle is adopted to optimize the particle size.

Sand making machine: Achieve the final sand making and form high-quality machine-made sand of 0.25-0.5mm.

Screening system: Through multi-layer screens, the finished products are accurately screened and stored or transported to the construction site.

III. Market price and substitutability of iron ore tailings sand

Iron ore tailings sand has been valued in recent years because it can be used as a building material. The price has soared from a few yuan to more than 50 yuan per ton, and the specific price varies from region to region. Tailings sand can not only replace river sand, but also be widely used in the construction industry under the premise of meeting national standards.

Advantages include:

Save the cost of construction and maintenance of tailings ponds.

Reduce damage to the environment and promote resource recycling.

Produce sintered bricks and cement with superior performance.

IV. Sand making equipment and return on investment

Sand making requires the use of efficient crushing equipment, such as single-cylinder hydraulic cone crushers and impact sand making machines. These equipment can not only guarantee high output, but also have good particle shape.

Single cylinder hydraulic cone crusher: suitable for medium and fine crushing, high production capacity, easy maintenance, prices range from tens of thousands to millions of yuan.

Impact sand making machine: specially used for sand making, with a production capacity of up to 650t/h, and the finished product particle size meets the standard.

Choosing a professional large manufacturer to ensure the quality of the equipment and after-sales service can provide protection for your investment.

Conclusion

Sand making from iron ore waste is not only an important way to solve resource waste, but also an effective means of environmental protection and sustainable development. Driven by policy support and market demand, the utilization prospects of iron ore waste are broad and worthy of investors' attention. If you have any questions about equipment selection or investment, please feel free to consult professional manufacturers for more information.
