250-500 tph Stone Crushing Plant

Built for Large-Scale Production

The 250-500 TPH (tons per hour) stone crushing production line is a high-capacity crushing solution specifically designed for large-scale quarries, sand and aggregate production bases, and major infrastructure projects (such as highways, railways, and hydroelectric power projects). Leveraging extensive industry experience, Baichy Machinery provides comprehensive end-to-end services—from design and equipment manufacturing to installation and commissioning—ensuring the production line operates with maximum efficiency and stability, thereby helping clients maximize their return on investment.

Our production line design centers on high reliability, low operating costs, and ease of maintenance; it can be flexibly configured to adapt to varying raw material characteristics and finished product specifications.

Core Process and Configuration

A typical 250-500 TPH production line generally employs the classic "coarse crushing + medium/fine crushing + screening" workflow. The following is our recommended cost-effective configuration plan:

1. Feeding and Coarse Crushing Section

• Raw Material Bin & Vibrating Feeder: The ZSW1100x4900 heavy-duty vibrating feeder ensures a uniform and continuous supply of material to the crusher, preventing blockages and serving as the cornerstone for the production line's stable operation.

• Primary Coarse Crushing – Jaw Crusher: Utilizes a PE900x1200 or high-performance C-series jaw crusher. With its powerful crushing force and deep-cavity design, it can effortlessly process various types of raw ores (such as granite and basalt) with particle sizes up to 750mm, performing reliable primary crushing.

2. Intermediate and Fine Crushing Section (Optional Configurations)

Based on the hardness of the raw materials and the required shape of the finished products, we offer two primary configurations for intermediate and fine crushing:

• Option A: Cone Crusher Configuration (Suitable for high-hardness materials)

This configuration utilizes the HPC400 or CS220 multi-cylinder hydraulic cone crusher. Employing the principle of inter-particle crushing (laminated crushing), this equipment produces finished aggregates with excellent particle shape and low needle-and-flaky content. It is particularly well-suited for processing hard, highly abrasive materials such as granite, river pebbles, and basalt; furthermore, its wear-resistant components offer a long service life, resulting in lower long-term operating costs.

• Option B: Impact Crusher Configuration (Suitable for medium-to-low hardness materials)

This configuration utilizes the PF1320 European-style impact crusher. This equipment crushes materials by harnessing impact energy, producing finished aggregates with a cubic shape and minimal stone dust content. It is highly suitable for processing medium-to-low hardness materials—such as limestone and dolomite—and offers the distinct advantages of low initial investment costs and a high crushing ratio.

3. Screening and Finished Product Section

• Vibrating Screens: Equipped with multi-layer YK series circular vibrating screens, this section efficiently classifies the crushed mixed materials, separating them into various finished aggregate specifications such as 0–5mm, 5–10mm, 10–20mm, and 20–31.5mm.

• Belt Conveyor System: A fully enclosed belt conveyor system connects the various processing sections, ensuring the smooth and continuous transfer of materials while simultaneously minimizing dust emissions.
