1000 TPH Crushed Stone Production Line Configuration
1000 tons per hour stone production line works well with limestone, granite, basalt and many other raw materials. It adopts the proven process from Shibang: primary jaw crusher + cone crusher + impact crusher + vertical shaft impact crusher. Equipped with heavy-duty feeding, screening and conveying machines, the line delivers high output, excellent particle shape and eco-friendly performance. Its finished products fully meet strict material standards for highways and high-speed railways.
1. Feeding and Primary Crushing
We use two F5X1860 vibrating feeders at the feeding section. Built with heavy-duty frames, these machines withstand heavy bin pressure and run steadily with strong vibration force. They can continuously and evenly feed large rocks up to 1000 mm in size. The built-in pre-screening function removes fine materials in advance to prevent blockages and ensure smooth operation for the whole line.
For primary crushing, two C6X1660 jaw crushers are installed. Featuring European style design and hydraulic discharge gap adjustment, these crushers handle large feed sizes and deliver a high crushing ratio. Each unit runs at 500 to 600 tons per hour, with output size ranging from 150 mm to 300 mm. The machines are wear-resistant and easy to maintain.
2. Secondary & Fine Crushing and Shaping
Two HST660 single-cylinder hydraulic cone crushers serve as secondary crushers. Designed specifically for hard rocks, they adopt the layer compression crushing principle to produce well-shaped stones. The discharge size is between 40 mm and 100 mm, with stable production and long service life for wear parts.
Next, two CI5X2023 impact crushers take charge of fine crushing. With a three-chamber crushing structure, they shape materials to 10–30 mm by impact force. The final products have a high percentage of cubical particles, which complies with standards for high-grade aggregates.
Two VSI6X1263 vertical shaft impact crushers are used for final shaping. Working in rock-on-rock mode, they further optimize particle shape and produce manufactured sand from 0 mm to 5 mm. The four-port impeller boosts working efficiency, and reversible wear parts help cut down operating costs.
3. Screening and Auxiliary Equipment
Three S5X3072 circular vibrating screens are used for classification. With multi-layer screen decks, they separate materials into different sizes: 0–5 mm, 5–10 mm, 10–20 mm and 20–31.5 mm. These screens work efficiently and rarely get clogged. Off-spec materials are sent back to relevant crushers to form a closed-loop production system.
Heavy-duty belt conveyors with belt width from 1.2 m to 1.4 m handle large material flow. The fully enclosed design keeps dust under control. We also match the line with a VU300S dry sand making system. It regulates stone powder content, creates zero wastewater and low dust emission, fully meeting green mine requirements.
