What is Sand Gravel Aggregate Production Equipment?
Sand and gravel aggregates are important raw materials for the construction of infrastructure such as buildings, roads, and bridges. A series of equipment is required in the production process to ensure production efficiency and product quality. The following will introduce some common sand and gravel aggregate production equipment. They work together to process raw stones into sand and gravel aggregates that meet different specifications and quality requirements.

Feeding Equipment
Feeding equipment is the starting point of the sand and gravel aggregate production line. Its main task is to evenly and continuously transport the raw stone to the crushing equipment. Common feeding equipment is a vibrating feeder.
Vibrating feeder:
The vibrating feeder provides excitation force through a vibrating motor to make the material move linearly in the feeding trough. Its advantages are simple structure, convenient operation, uniform feeding, and can ensure the stability of material flow, which is suitable for processing relatively uniform materials.
Crushing Equipment
Crushing equipment is the core part of the sand and gravel aggregate production line, which is used to crush large pieces of raw stone into aggregates of required specifications. Common crushing equipment includes jaw crusher, vertical compound crusher and cone crusher.
Jaw crusher
The jaw crusher is suitable for primary crushing, processing large pieces of materials with high hardness, with advantages such as high output, simple structure, and convenient maintenance.
Vertical compound crusher:
Vertical compound crusher is a multifunctional crushing equipment suitable for crushing medium-hard and below materials. Its main features are high crushing efficiency, low energy consumption, and good particle size control ability. This equipment is especially suitable for occasions with strict requirements on aggregate particle size, and can effectively reduce the load of subsequent crushing.
Cone crusher
Mainly used for secondary crushing, it can effectively control the particle size of finished aggregates, especially suitable for the demand for fine-grained aggregates, and has high crushing efficiency.
Screening Equipment
In the sand and gravel aggregate production line, screening equipment is mainly used to classify the crushed materials according to particle size. Common screening equipment includes square swing screens and high-angle swing probability screens, which effectively screen materials through screens of different apertures to make the finished aggregate meet the specification requirements.
Square Gyratory Vibrating screen
The square gyratory vibrating screen adopts advanced swing screening technology to achieve material screening and grading through the swinging and reciprocating motion of the screen body. The equipment has high output and screening accuracy, with an output of 5-25 tons per hour and an applicable particle size range of 2-200 mesh. The square swing screen is not only suitable for conventional screening tasks, but also can handle situations where the material particle size distribution is wide and contains a large amount of fine materials, and has excellent screening effect.
High-angle swing probability screen
The high-angle swing probability screen is based on the compact square swing screen, with a larger inclination design, thereby increasing the speed of material unloading. The equipment is particularly suitable for handling materials that are easy to screen and have larger particle sizes, with higher output, up to 5-100 tons per hour, and an applicable particle size range of 2-100 mesh. It is especially suitable for handling high-yield, large-size aggregates. The high-angle swing probability screen is regarded as an ideal alternative to the traditional probability screen, which can complete the large-flow screening task more efficiently.
Conveying equipment
The belt conveyor is one of the most commonly used conveying equipment in the sand and gravel production line, responsible for the continuous conveying of materials.
Belt conveyor
The sand belt conveyor is suitable for long-distance and large-volume material transportation, and is an indispensable automatic conveying equipment in the sand and gravel aggregate production line. It has the advantages of stable operation, strong conveying capacity, and easy maintenance.
Chain conveyor
The chain conveyor is suitable for the transportation of heavy, large or irregularly shaped materials. The equipment can stably convey the material to the designated position through the drive of the chain. Chain conveyors are widely used in material transportation in crushing, screening and other links, especially suitable for handling some irregular and large materials.
Lifting equipment
Lifting equipment is used to transport materials from low to high places, and is often used for vertical transportation. Common lifting equipment is bucket elevator.
Bucket elevator
Bucket elevator is suitable for vertical transportation of fine particles or powdered materials, running smoothly and efficiently, ensuring the smoothness of the production line.
Washing equipment
In some applications with high requirements for aggregate quality, washing equipment is used to remove impurities and soil in the material to ensure the purity of the final product. Common washing equipment includes spiral sand washing machine and wheel bucket sand washing machine.
Spiral sand washing machine
Water flow and material friction are used to remove impurities through the rotation of spiral blades, which is particularly suitable for cleaning fine-grained sand and gravel.
Wheel bucket sand washing machine: through the mixing effect of the rotating wheel bucket and water flow, the soil and impurities in the large-particle material are cleaned, which is particularly suitable for the cleaning of larger particles.
Conclusion
In summary, the efficient operation of the sand and gravel aggregate production line depends on the close cooperation of equipment in each link. Reasonable selection and configuration of equipment based on the properties of raw materials, output requirements and quality standards of aggregates can not only improve production efficiency, but also effectively reduce production costs, ensuring the provision of high-quality sand and gravel aggregates for various construction projects.
