(1) Raw material warehouse

Raw material warehouse is specially designed to store raw materials required for production. The scale can be large or small according to demand. Large warehouses are often equipped with spacious cargo yards, which are especially suitable for large sand and gravel yards; small yards can be flexibly selected according to the situation to ensure the safe storage and efficient management of raw materials.

(2) Feeding equipment

The vibrating feeder is the core equipment. It can stably, regularly and continuously feed block and granular raw materials into the crusher, ensuring a smooth and efficient crushing process. It is the key link between raw material storage and crushing processing.

(3) Crushing equipment

The jaw crusher is good at coarse crushing, the cone crusher is suitable for medium and fine crushing of hard materials, the impact crusher is good at processing soft materials and producing high-quality particles, and the hammer crusher is suitable for fine crushing of medium hardness materials. When choosing, it is necessary to comprehensively consider the characteristics of the raw materials, production needs and economic benefits, and flexibly configure to optimize the overall efficiency.

(4) Sand making equipment

Sand making is crucial in the production of sand and gravel, and affects the quality of the finished product. Impact sand making machines are popular in the market because they combine sand making and shaping. The finished sand has excellent particle shape, uniform particle size, and reasonable gradation. They are the preferred equipment for improving product quality.

(5) Screening equipment

The vibrating screen plays a key role in the sand and gravel production line. It accurately checks the quality of the finished products in each processing link to ensure that each grain of sand and gravel meets the standards. Qualified sand and gravel pass through screening and enter the next production stage smoothly, while those that fail to meet the standards are automatically returned for reprocessing. This process effectively improves the qualified rate of the final product and the overall production efficiency.

(6) Sand washing equipment

Sand washing machines are currently important sand and gravel washing equipment. Their main function is to remove impurities from the finished sand and gravel to improve the purity of the finished sand and gravel.

(7) Conveying equipment

The conveyor belt, also known as the belt conveyor, is an important equipment connecting the entire production line, which plays the role of carrying and transporting materials.
