400-450tph high-quality sand and gravel production line in Poland

This production line makes full use of the abundant local limestone resources and integrates multiple stages including crushing, screening, and sand making to produce four types of finished aggregates in different size specifications: 0–5mm, 5–10mm, 10–20mm, and 20–30.5mm. Each stage of the process is carefully optimized to ensure high efficiency and stable output. The final aggregates feature excellent particle shape, uniform gradation, and low flakiness index, making them ideal for use in high-quality construction applications. All finished products fully comply with relevant industry standards for particle size, strength, and durability, and have been well received by end users for their superior quality and performance.
