Sand and gravel aggregates are widely used in various construction fields such as water conservancy and hydropower, construction, bridges, and highways. The quality of aggregate directly affects the strength of concrete. What determines the quality of sand and gravel aggregate? How to improve the quality of sand aggregate? What kind of sand and gravel aggregate production equipment is used?

1. What are the factors that affect the quality of sand and gravel aggregate?

The quality of sand and gravel aggregate is directly related to the nature of the processed rock, equipment, and processing technology.

Different rocks have different physical and chemical properties, and they also vary in specific gravity, porosity, compressive strength, and tensile strength. At the same time, rocks with different properties will have different choices of equipment and processes.

2. What are the sand and gravel aggregate production equipment?

The equipment needed for the production of sand and gravel aggregates includes feeders, vibrating screens, crushers, sand making machines, and conveyor belts. The types of crushers mainly include jaw crusher, impact crusher, cone crusher, hammer crusher, double roller crusher and so on. Sand making machines mainly include impact crusher, fine crusher, hammer crusher and so on. Different crushing and sand making equipment have different applicable materials and processed finished products.

3. What is the specific configuration of the 200 tons of sand and gravel aggregate production line?

In the production of sand and gravel aggregates, our commonly used crushing equipment includes jaw crusher, impact crusher, cone crusher and impact crusher. We will match and combine these crushing equipment according to the characteristics of the processed stone, the quality requirements of the finished product and the setting of production capacity and other factors.

Aggregate is generally divided into coarse aggregate and fine aggregate. Coarse aggregates are rock particles with a particle size greater than 4.75 mm, mainly pebbles and crushed stones. Fine aggregate is rock with a particle size of less than 4.75m, such as river sand, mountain sand, sea sand, etc. According to the characteristics of these two materials, the configuration of our entire production line is mainly divided into four parts: feeding, crushing, sand making and screening.

The specific configuration of the 200 tons of sand aggregate production line is: feeder, jaw crusher, impact crusher or cone crusher, sand making machine and vibrating screen.
