1. PEMBUKAAN PAINPOINT DRIVEN

Menguruskan sanga adalah kesesakan yang berterusan dengan kos yang ketara. Adakah anda menghadapi cabaran operasi ini?
Downtime yang tidak dirancang: Frequent clogging and abrasive wear in standard crushers lead to inconsistent throughput and costly, reactive maintenance stops.
Kos Operasi yang Tinggi: Penggunaan tenaga yang berlebihan bagi setiap tan yang diproses, combined with the labor and parts expense of maintaining illsuited equipment, menghakis margin keuntungan.
Ketidakkonsistenan Produk: Inability to control final aggregate size reliably results in offspec material, reducing its market value for secondary applications like road base or cement additives.
Keselamatan & Environmental Risk: Dust generation during crushing and the potential for uncontained metallic remnants pose health and compliance hazards.

Soalan teras untuk pengurus loji ialah: how do you transform a waste stream into a consistent, profitable product without compromising plant uptime? The answer lies in purposeengineered processing technology.

2. GAMBARAN KESELURUHAN PRODUK

An FDAapproved slag crusher plant is a stationary or semimobile processing system specifically engineered to reduce aircooled blast furnace (BF) slag or steel slag into specified aggregate sizes. For slag used in applications with potential human contact, such as filtration media or certain agricultural uses, FDA compliance of material contact parts ensures no chemical contamination.

Aliran Kerja Operasi:
1. Penghancuran utama: Suapan sanga besar (up to ~1000mm) is reduced via a robust jaw crusher or impactor.
2. Pemulihan ferus: A suspended magnet or magnetic pulley extracts remaining metallic iron for recycling.
3. Penghancuran Menengah/Tertiari: Cone crushers or further impactors provide precise size reduction to the target specification.
4. Pemeriksaan & Stok: Vibrating screens separate the crushed slag into defined fractions (mis., 20mm, 10mm, habuk) for conveyor transfer to stockpiles.

Skop Permohonan: Processing aircooled BF slag, mencuri strok, and other metallurgical byproducts for use as construction aggregate, pemberat rel, or industrial feedstock.

Batasan: Not designed for molten slag; feed size and hardness must be within engineered specifications. Highly abrasive or chemically unpredictable feed can accelerate wear part consumption.
