A customer from Laos purchased a limestone crushing line from Shimeite Machinery Company, which can crush 500 tons per hour.

The 500t/h Limestone Crusher Plant Configuration

The plant adopts a professional three‑stage crushing and closed‑circuit screening process, with optimized flow for maximum efficiency.

1.Primary Crushing Station

Jaw Crusher PE900×1200

As the main primary crusher, it processes raw limestone up to 750mm and reduces it to 0–200mm. With robust structure and deep crushing chamber, it ensures stable performance under heavy‑duty continuous working conditions.

2.Secondary Crushing Stage

Multi Cylinder Cone Crusher HPC500

Used for medium crushing, it processes materials to 0–60mm with uniform particle shape. It features automatic adjustment and overload protection, keeping stable output quality.

3.Tertiary Crushing Stage

Dual Impact Crushers PFW1315 (parallel installation)

Advantages:

• High throughput to meet 500t/h capacity

• Excellent cubic particle shape for concrete and asphalt

• High flexibility to adjust product mix by changing crusher parameters

4.Screening System

Dual Vibrating Screens YK2460

Two‑deck heavy‑duty screens realize accurate classification into multiple sizes. Oversized material is returned to crushers for reprocessing, ensuring all products meet required specifications.
