Kyrgyzstan River Pebble Crushing Production Line
In the sand and gravel aggregate production industry, building a highly efficient and stable crushing production line is crucial for enterprises to improve capacity and economic benefits. For medium-sized sand and gravel plants, a 300-ton/hour (300t/h) aggregate crushing production line is an ideal solution for processing hard rocks such as granite, limestone, and basalt. This article will provide a detailed flow chart of a 300-ton aggregate crushing production line, deeply analyzing its core equipment, scientific process flow, investment costs, and core advantages to help you plan your layout scientifically and maximize benefits.

1. Core Equipment Configuration of a 300-ton/hour Aggregate Crushing Production Line
To achieve high output and excellent finished product particle size, this solution recommends the classic three-stage closed-loop combination of "jaw crusher + cone crusher + vibrating screen". Its main equipment includes:
• Feeding equipment: Vibrating feeder (such as the GZD series), ensuring uniform and continuous feeding, preventing material blockage in the primary crusher, and ensuring smooth start-up of the production line.
• Primary Crushing Equipment: Jaw crusher (e.g., PE-1200×1500), with its high crushing ratio, efficiently completes the primary crushing of large raw materials.
• Secondary and Fine Crushing Equipment: Cone crusher (e.g., HPT300), designed for medium to high hardness rocks, employs the principle of layered crushing, producing excellent particle shape, and is key to achieving multi-specification aggregate production.
• Screening Equipment: Multi-layer vibrating screen (e.g., 3YK3070), can accurately classify aggregates into various specifications in high demand in the market, such as 0-5mm (manufactured sand), 5-10mm, and 10-20mm.
• Conveying System: Belt conveyor (e.g., B1000 type), responsible for the entire material flow, connecting various process links, and ensuring production continuity.

Step-by-step process analysis:
1. Feeding: Raw materials are evenly fed into the jaw crusher via a vibrating feeder.
2. Coarse Crushing: The jaw crusher crushes large stones to a particle size of ≤200mm in one pass.
3. Medium and Fine Crushing: After coarse crushing, the material is conveyed into the cone crusher for further crushing to ≤50mm.
4. Screening and Closed-Circuit Cycle: The crushed material is graded by a vibrating screen. Aggregates of the qualified particle size are directly output as finished products. Oversized particles that do not meet the standards are returned to the cone crusher for further crushing, forming a closed-loop cycle that significantly improves the yield and particle quality.
5. Finished Product Output: Various sizes of qualified aggregates (e.g., 0-5mm, 5-10mm, 10-20mm) are transported to the finished product stockpile by conveyors.
3. Four Core Advantages of the Production Line
• High and Stable Output: Designed with a capacity of 300 tons per hour, it perfectly matches the capacity requirements of medium-sized sand and gravel plants, ensuring stable and reliable operation.
• Energy Saving and Environmental Protection: The cone crusher's layered crushing process reduces energy consumption by approximately 30% compared to traditional equipment; the production line can be equipped with a dust removal and noise reduction system to meet environmental protection requirements.
• Intelligent Control: Utilizing a PLC central control system, it achieves automated operation, reduces manual intervention, and facilitates easier fault diagnosis.
• Strong Adaptability: The core equipment is designed for hard rock and can easily process various materials such as granite, river pebbles, and basalt, making it widely applicable.
4. Frequently Asked Questions (FAQ) about a 300 t/h aggregate crushing production line
Q1: How much site space is needed to build a 300 t/h production line?
A: It is recommended that the site be at least 80 meters long and 50 meters wide. The specific layout can be flexibly adjusted according to the actual terrain and equipment model.
Q2: What is the investment cost of a 300 t/h aggregate crushing production line?
A: Equipment investment varies depending on configuration, brand, and level of automation, typically ranging from 2 million to 5 million RMB (including main and auxiliary equipment). A precise quote requires consideration of specific material and finished product requirements.
Q3: What specifications of finished aggregate can be produced?
A: By adjusting the parameters of the crusher and vibrating screen, different specifications of coarse and fine aggregates, such as 0-5mm (high-quality manufactured sand), 5-10mm, 10-20mm, and 16-31.5mm, can be produced to meet the needs of concrete and various engineering construction projects.
