In the mining and construction aggregate industry, jaw crushers, impact crushers, cone crushers and sand making machines are the core crushing equipment of SBMmill. We have been studying hard and combining market demand and industry experience to develop various types of crushers to form high, medium and low configurations to meet more production needs of customers.
Stone crushing production line process flow
The process flow of the gravel production line is roughly divided into: silo – feeding – crushing (primary crushing, secondary crushing, tertiary crushing or sand making and shaping)-screening – transportation – sand washing – drying – storage. Each step requires different industrial equipment. Appropriate processing equipment should be selected based on the actual situation of the gravel production line, production capacity, stone size, budget and other requirements.
● Necessary procedures
The core of the gravel production line is feeding, crushing, screening and transportation. The stone is first fed to the coarse crusher (jaw crusher) by the feeder for coarse crushing. The coarse crushed products are screened by the vibrating screen, and the qualified materials are sent to the secondary crushing equipment by the belt conveyor(the secondary crushing equipment includes cone crusher and impact crusher. Cone crusher is often used to process high-hardness materials, such as granite, basalt, etc., with high compressive strength; Impact crusher It is often used to process materials with medium and low hardness, such as limestone, bluestone, etc., and the discharging particles are good). The unqualified materials are sent back to the coarse crusher by the belt conveyor for re-crushing.
Then in the second and third stages of crushing, this pattern is repeated to form a cycle until the finished materials are screened out.
● Additional processes
Silo: Not every production line requires a silo. If the raw materials are transported from elsewhere, you need a silo as a buffer. If the raw materials are close to each other, they can be directly fed to the feeder by an excavator or transport truck.
Sand washing: If the quality requirements of the finished product are high, or there are too many stone powders and impurities in the finished product, which affect the gradation and quality of the finished product, a sand washing machine is required for cleaning.
Drying: The sand that has gone through the sand washing step contains too much water. If you rely on it to dehydrate naturally, it will take too long. In order to speed up this time, you need to use a dryer.
Storage: Some production lines are built near construction sites, and the finished products can be used directly without storage. Many sand and gravel plants produce sand but cannot find buyers immediately. The finished products need to be stored first and then sold.
Characteristics of stone crushing production line
1. Efficiency: The stone production line equipment is highly efficient and can quickly process raw materials into finished products and improve production efficiency.
2. Automation: Modern stone production line equipment tends to be automated, reducing manual operations and improving production accuracy and efficiency.
3. Versatility: Stone production line equipment can process different types of stones to meet the needs of different fields.
4. Reliability: Stone production line equipment has high reliability and can ensure long-term stable operation.
5. Environmental protection: Modern stone production line equipment pays attention to environmental protection and reduces pollution such as noise and dust.

Common standard configurations of gravel production lines
1. Processing of high hardness materials: feeder + jaw crusher + cone crusher + vibrating screen + conveyor;
2. Processing of medium and low hardness materials: feeder + jaw crusher + impact crusher + vibrating screen + conveyor;
3. For multi-stage operations of gravel and sand making: feeder + jaw crusher + cone crusher/impact crusher + sand making machine + vibrating screen + conveyor;
4. It can achieve one-time forming of gravel: feeder + hammer crusher + vibrating screen + conveyor.
The above gravel production line configuration is easy to install for some gravel processing plants with high output, flat terrain and close raw materials. The site does not need to be organized, and it can be installed directly by piling.
Of course, for customers with complex terrain or other special circumstances, SBMmill will develop professional production line plans based on customer needs.
