1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Managing slag is a critical but costly bottleneck in metal production and recycling operations. Xử lý kém hiệu quả ảnh hưởng trực tiếp đến lợi nhuận của bạn thông qua việc hao mòn thiết bị, disposal expenses, và mất doanh thu từ kim loại chưa được phục hồi. Bạn có đang phải đối mặt với những thử thách dai dẳng này?

Chi phí mài mòn cao: Tính chất mài mòn của xỉ làm phân hủy nhanh chóng các bộ phận máy nghiền tiêu chuẩn, leading to frequent downtime for liner changes and rotor repairs, with replacement part costs cutting into operational budgets.
Phục hồi kim loại không hiệu quả: Inadequate crushing leaves valuable ferrous and nonferrous metals locked within slag aggregates, resulting in significant lost revenue from unrecovered material.
Dust and Emission Control Failures: Processing generates fine particulate matter, creating compliance risks with environmental health and safety (EHS) standards and exposing personnel to hazardous dust.
Thông lượng không đáng tin cậy: Crushers not engineered for slag’s specific hardness and variability suffer from blockages, công suất giảm, and inconsistent output sizing, disrupting downstream material handling.
Regulatory Compliance Burden: Equipment that fails to meet stringent environmental directives, such as RoHS (Hạn chế các chất độc hại), can restrict the marketability of your processed slag byproducts.

Câu hỏi trọng tâm đối với các nhà quản lý nhà máy là đây: làm thế nào bạn có thể đạt được sự tin cậy, highvolume slag reduction while maximizing metal recovery, đảm bảo tuân thủ môi trường, and controlling total cost of ownership?

2. TỔNG QUAN SẢN PHẨM

A RoHS compliant slag crusher plant is a purposeengineered stationary or semimobile system designed specifically for the primary and secondary crushing of metallurgical slag. It integrates robust size reduction technology with material handling and dust suppression systems to process slag into a calibrated aggregate while ensuring the final product adheres to RoHS substance restriction guidelines.

Quy trình hoạt động:
1. Cho ăn & Sàng lọc trước: Slag feedstock is loaded via excavator or conveyor into a hopper, often passing through a grizzly or scalping screen to remove oversize debris and direct fines away from the crusher.
2. Giảm kích thước chính: Máy nghiền lõi (thường là máy nghiền hàm hoặc máy nghiền tác động) receives the material, applying high mechanical force to break down large slag chunks.
3. Tách kim loại & Sự hồi phục: Crushed material passes over an overhead magnetic separator (or eddy current separator for nonferrous metals) to extract liberated metallic fractions for recycling.
4. Nghiền thứ cấp & Định cỡ (Không bắt buộc): A secondary cone or impact crusher further reduces material to precise specifications, followed by screening decks to classify aggregate into defined fractions (ví dụ., 05mm, 520mm).
5. Ngăn chặn bụi & Điều khiển: Integrated water spray nozzles at transfer points and enclosed conveyor sections actively suppress dust emissions throughout the process.

Phạm vi ứng dụng & Hạn chế:
Phạm vi: Lý tưởng cho các nhà máy thép tích hợp, xưởng đúc, nhà máy luyện đồng/niken, and metal recycling facilities processing blast furnace slag, đánh cắp đột quỵ, or nonferrous slags. Output is a commercially viable construction aggregate.
Hạn chế: Not designed for primary ore processing or extremely highmoisture materials without predrying. Plant throughput is fixed based on design; major capacity increases require system modification.
