2. TỔNG QUAN SẢN PHẨM

This 250300tph stationary stone crushing plant is a complete, hardrock processing system engineered for continuous, sản xuất khối lượng lớn cốt liệu cho xây dựng, nền đường, và dằn đường sắt. It is configured for primary, sơ trung, and tertiary crushing stages to produce precisely graded final products.

Quy trình hoạt động:
1. Giảm sơ cấp: Đá khai thác lớn (≤750mm) được đưa vào máy nghiền hàm sơ cấp mạnh mẽ để giảm kích thước ban đầu.
2. Nghiền thứ cấp & Sàng lọc: The output is conveyed to a secondary cone crusher. Material is then screened; oversized material is recirculated back to the secondary crusher (mạch kín).
3. Tertiary Shaping/Final Screening: Depending on configuration, a tertiary impact crusher or fine cone crusher further shapes the aggregate. Final screening decks separate the output into multiple specified product sizes (ví dụ., 05mm, 510mm, 1020mm).

Phạm vi ứng dụng & Hạn chế:
Phạm vi: Lý tưởng cho đá granit, đá bazan, đá vôi, and other medium to highabrasiveness rocks. Suited for largescale quarry operations, các dự án cơ sở hạ tầng lớn yêu cầu sản xuất tổng hợp tại chỗ, and dedicated commercial aggregate suppliers.
Hạn chế: Not designed for very soft, clayheavy materials without significant preprocessing. Requires stable foundation and substantial electrical supply. Feed size must be controlled per design parameters.
