Specifications and Uses of Gravel 05, 12 and 13, Which Crusher has the Best Gravel Shape?

Gravel classified under the specification code 05, 12 and 13 typically refers to specific types of gravel aggregates used in construction, including concrete production, road base material, and drainage systems. Here are some general specifications and uses for this type of gravel:

Specifications of Gravel 05, 12 and 13:

1.Size: Gravel can vary in size, but it is usually classified as coarse aggregate. The size of gravel can range from 4.75 mm to 75 mm (No. 4 to 3 inches).

2.Shape: The shape of the gravel particles can affect their performance. Well-rounded gravel is often preferred for concrete, while angular gravel may be better for applications requiring interlocking.

3.Material: Usually composed of crushed stone, river gravel, or a blend of both. The material should be clean and free from deleterious substances.

4.Gradation: The distribution of particle sizes is important for various applications. Well-graded gravel provides better compaction and stability.

5.Strength: The gravel must meet certain strength criteria, especially for structural applications.

Uses of Gravel 05, 12 and 13:

1.Concrete Production: Used as aggregate in concrete for buildings, roads, and other structures.

2.Road Base Material: Acts as a foundational layer under asphalt or concrete pavements.

3.Drainage Systems: Used in French drains, septic systems, and other drainage applications to facilitate water flow.

4.Landscaping: Often used as decorative gravel or in pathways and driveways.

5.Erosion Control: Helps prevent soil erosion in landscaping and civil engineering projects.

Best Crushers for Gravel Shape:

When it comes to the production of gravel with optimal shape, different types of crushers can be used. Two commonly used types are:

1.Cone Crushers:

Pros: Produce well-shaped, uniform gravel with a high percentage of crushed faces. They are excellent for producing high-quality aggregates.

Cons: It may not be as efficient for very small sizes compared to other crushers.

2.Impact Crushers:

Pros: Effective for producing a high percentage of cubic-shaped gravel, especially if the material is not overly hard. They create more fractures and can generate a more desirable shape.

Cons: May produce more fine materials, which can be undesirable in some applications.

In conclusion, to ensure the best gravel shape, a combination of cone and impact crushers is often used in a crushing circuit. The choice of crusher may depend on the specific requirements of the project and the characteristics of the raw material being processed.
