The 3,000-ton daily basalt crushing production line adopts the full-process design of "coarse crushing + medium and fine crushing + shaping and screening". The core equipment includes high-energy jaw crusher, multi-cylinder cone crusher and centrifugal impact crusher. Through three-stage crushing and two-stage screening processes, it can simultaneously produce high-speed railway ballast, fine sand and road surface materials, realizing efficient and intelligent production.

Configuration plan of 3,000-ton daily efficient and intelligent basalt crushing production line:

1. Equipment configuration: full process coverage, excellent performance

The production line adopts the full-process design of "coarse crushing + medium and fine crushing + shaping and screening". The core equipment includes vibrating feeder ZSW-420×110, HJ98 high-energy jaw crusher, HPT300 multi-cylinder hydraulic cone crusher, VSI5X8522 centrifugal impact crusher (shaping machine) and two vibrating screens (3Y2460, 3Y2160).

1. Vibrating feeder ZSW-420×110

As the "front guard" of the production line, this equipment effectively avoids raw material accumulation through uniform feeding and ensures the stability of the coarse crushing link. Its heavy-duty vibrating motor and spring shock-absorbing structure can meet the continuous transportation needs of high-hardness basalt.

2. HJ98 High-Energy Jaw Crusher

As the core equipment for coarse crushing, HJ98 adopts a deep-cavity crushing design with a feed port size of 980×650mm, which can process large pieces of basalt at one time (maximum feed size 500mm). Its hydraulic adjustment discharge port function can quickly adjust the discharge size to 100-200mm, providing ideal raw materials for subsequent medium and fine crushing.

3. HPT300 Multi-Cylinder Hydraulic Cone Crusher

As the "efficiency leader" of the medium and fine crushing link, HPT300 further crushes the coarsely crushed basalt to 30-70mm through the principle of lamination crushing. Its multi-cylinder hydraulic protection system can automatically adjust the discharge port to prevent overload damage and ensure uniform discharge particle size.

4. VSI5X8522 centrifugal impact crusher (shaper)

For the shaping needs of 0-18mm fine materials, the equipment switches between "stone hitting stone" and "stone hitting iron" to process sharp-edged crushed stones into fine sand (0-5mm) and highway road surface materials (5-18mm) with rounded grains

5. Vibrating screens 3Y2460 and 3Y2160

The double-layer screen structure can simultaneously separate 30-70mm ballast stones, 0-5mm fine sand and 5-18mm road surface materials. The modular design facilitates quick replacement of screens to meet different particle size requirements.

2. Process flow: graded crushing

The production line adopts the "three-stage crushing + two-stage screening" process:

Coarse crushing stage

The basalt raw material is evenly transported to the HJ98 jaw crusher by a vibrating feeder, crushed to 100-200mm and then transported by a belt conveyor.

Medium and fine crushing stage

The coarse crushed material enters the HPT300 cone crusher, and is crushed to 30-70mm ballast stone for secondary crushing, which is directly used as aggregate for high-speed rail; the 0-18mm fine material enters the shaping machine.

Shaping and screening stage

VSI5X8522 processes the fine material into 0-5mm fine sand and 5-18mm road surface material, which are graded by the vibrating screen and stored.

The process is connected by a closed loop belt conveyor to reduce material transfer losses, and the linkage control of the shaping machine and the vibrating screen is used to achieve flexible adjustment of the output of fine aggregate and fine aggregate.
