12-stone particle size of 10-20 mm is suitable for small buildings, and 13-stone particle size of 16-31.5 mm is suitable for large buildings. Production requires the selection of appropriate equipment, such as jaw, cone, and impact crushers, considering the model, performance, and cost to ensure efficient production and stone quality.

In the construction industry, stone is an important aggregate and is widely used in the production of concrete and mortar. Among them, 12-stone and 13-stone are two common specifications. Understanding their characteristics and differences is crucial to the selection of building materials.

How to choose crushing equipment according to stone particle type

The difference between 12-stone and 13-stone

The main difference between 12-stone and 13-stone is the particle size. The particle size of 12-stone is generally between 10 mm and 20 mm, which is suitable for the construction of small buildings and can provide better concrete fluidity and safety. The particle size of 13-stone is between 16 mm and 31.5 mm, which is more suitable for foundation pouring of large buildings, such as building foundations and road foundations.

Equipment selection for producing 12 and 13 stone

To produce high-quality 12 stone and 13 stone, suitable mining equipment is essential. The following are several commonly used crushing equipment:

Jaw crusher: suitable for a variety of stones, with a wide range of discharging particle sizes, which can meet the production needs of 12 stone and 13 stone. Its high efficiency and large output make it an ideal choice.

Cone crusher: specially designed for high hardness materials, with moderate discharging particle size, very suitable for the needs of large sand and gravel plants.

Impact crusher: mainly used for medium and low hardness materials, can produce 12 stone and 13 stone at the same time, with good shaping effect.

When choosing equipment, it is necessary to consider the equipment model, performance and production cost to ensure efficient production and high quality of stone.

Conclusion

Whether it is 12 stone or 13 stone, it is crucial to choose the right equipment and understand their characteristics. By configuring the production line reasonably, you can not only improve production efficiency, but also ensure the quality of stone to meet the various needs of the construction industry. If you are considering entering the sand and gravel industry, it is worth taking a closer look at these machines and their suitability to lay a solid foundation for your project.
