The 600 tons per hour sand and aggregate production line built by Dahua Heavy Industry in Indonesia adopts multi-stage crushing and screening technology, combined with high-efficiency and environmentally friendly equipment. The specific configuration and technical features are as follows:

 

Core crushing equipment configuration

1. JC110 Jaw Crusher 

As a primary crushing equipment, it is responsible for processing large pieces of raw materials (≤900mm feed size), has a high crushing ratio and wear resistance, and is suitable for hard rock crushing scenarios.

 

Referring to the processing capacity of similar HD jaw crushers (50-750t/h), JC110 can meet the primary coarse crushing needs.

 

2. GPY500S Single-cylinder Cone Crusher 

Used in the medium and fine crushing link, the particle size control is achieved through hydraulic adjustment of the discharge port, and it is suitable for crushing high-hardness ores.

 

The GPY series has an intelligent control system that can monitor parameters such as oil temperature and load in real time to ensure stable operation; its compact structure and low maintenance cost are suitable for complex working conditions in Indonesia.

 

3. PFQ1315 Impact Crusher 

As a secondary crushing equipment, it is used for material shaping and improving the quality of finished product particles. Dahua impact crusher is known for its strong impact resistance, especially suitable for efficient crushing of medium hardness materials.

 

4.  PLS-1000II Vertical Shaft Crusher

As a key equipment for sand making, it uses the impact crushing principle to generate 0-5mm machine-made sand, with both "stone hitting stone" and "stone hitting iron" modes, and can adjust the fineness modulus of the finished sand.

Auxiliary equipment and system integration

 

1. Vibrating screen and feeder

Multi-stage vibrating screen realizes sand and gravel classification (such as 0-5mm sand, 5-10mm gravel, etc.), and ZSW series feeder ensures uniform feeding and reduces equipment idling.

 

2. Sand washing machine

Remove dust and impurities on the surface of aggregates, improve the cleanliness of finished products, and meet the standard requirements of Southeast Asian markets for high-quality sand and gravel.

 

3. Environmental protection and intelligent control

Dust collection, spraying and noise reduction devices are configured to reduce dust and noise pollution.

 

Remote monitoring is achieved through the PLC system to optimize the production process and reduce manual intervention.

 

Advantages of production line design

- Site adaptability: The equipment layout is compact, and the transportation path is optimized in combination with the Indonesian terrain to reduce infrastructure costs.

 

- Energy saving and high efficiency: The use of low-energy motors and laminated crushing technology reduces unit energy consumption by 15%-20% compared with traditional processes.

 

- Easy maintenance: Key components (such as GPY500S lining) are made of highly wear-resistant materials to extend service life and reduce downtime.

 

Typical application scenarios

This production line is suitable for the processing of high-hardness ores such as basalt and granite. It can produce 12/13 gravel and machine-made sand that meet the needs of construction, roads, and concrete mixing stations, meeting the needs of Indonesian infrastructure construction projects.
