With the rapid development of infrastructure construction, the demand for sand and gravel aggregates continues to increase. However, the shortage of natural sand makes manufactured sand an ideal option to fill this gap. To meet environmental protection requirements, how should an environmentally friendly sand and gravel aggregate production line be configured? How can environmentally friendly production be achieved? What key points should be considered during configuration?

Environmentally Friendly Sand and Gravel Equipment

Configuration of an Environmentally Friendly Sand and Gravel Aggregate Production Line

An environmentally friendly sand and gravel aggregate production line typically includes a crusher, sand maker, vibrating equipment, and supporting equipment. The specific configuration needs to be customized based on the type of raw materials, production scale, and finished product requirements. Generally speaking, the process flow of a sand and gravel aggregate production line consists of three main steps: coarse crushing, fine crushing, and screening.

Coarse Crushing Equipment: Jaw crushers, gyratory crushers, or hammer crushers are commonly used.

Secondary Crushing Equipment: Cone crushers or impact crushers are commonly used.

Finally Crushing Equipment: Vertical impact crushers (sand makers) are commonly used for fine crushing and shaping.

The entire production line operates as follows: Large lumps of stone are fed by dump trucks into a vibrating feeder, where they are coarsely crushed in a jaw crusher. The crushed stone then enters a cone crusher or impact crusher for secondary crushing. The crushed stone is then screened by a vibrating screen. Substandard stone returns to the cone crusher for further crushing, ultimately resulting in finished products of varying sizes.

How to Achieve Environmentally Friendly Production?

For sand and gravel plants, environmentally friendly production primarily focuses on dust, noise, and wastewater.

Dust Control:

Enclosed Production: The production line utilizes a partially enclosed design and is equipped with multi-effect dust removal equipment. Dust is collected via dust hoods to reduce dust pollution.

Sprayer Dust Removal: Sprayers are installed at key locations to further reduce dust.

Noise Control:

Enclosed Prefabricated Room Design: Reducing noise pollution through enclosed prefabricated rooms is a key factor in achieving environmentally friendly production.

Silencers: In areas where noise is strictly controlled, shielding or silencers are installed to reduce noise.

Wastewater Treatment:

Sewage Sedimentation Tanks: During the sand washing process, sewage sedimentation tanks are constructed to recycle sand washing wastewater. The precipitated sludge and waste soil can be used for mine reclamation.

Key Points in Designing an Environmentally Friendly Sand and Gravel Production Line

Adapt to Material and Site Conditions:

Select appropriate equipment and process solutions to avoid a one-size-fits-all approach. Tailor the production plan based on the raw material characteristics and site conditions.

Modular Design:

The modular design ensures a rational layout of the crushing and screening modules and an orderly arrangement of conveyor belts, ensuring efficient production line operation.

High-Quality Finished Product:

The use of efficient sand making equipment ensures stable gradation control and fine particle size in the finished product, meeting the requirements for high-standard construction sand and gravel.
