Key Stages of the Manganese Ore Beneficiation Production Line

1. Crushing Section

The crushing stage is pivotal for reducing raw manganese ore to a particle size that enables efficient mineral liberation in subsequent grinding. This section employs a closed-circuit crushing circuit to achieve uniform particle size distribution.

• Feeder:A vibrating or apron feeder is used to meter the raw ore into the crushing circuit. It ensures a steady, controlled feed rate, preventing overloading of crushers and maintaining process stability.
• PE Jaw Crusher (Penggilingan Awal):Minangka tahap pertama saka pengurangan ukuran, PE jaw crusher nggunakake gaya kompresif liwat pelat rahang bolak-balik kanggo ngurangi bijih mentah (biasane
• Cone Crusher (Penggilingan Sekunder):Cone crusher beroperasi kanthi mantel muter ing njero concave sing mandheg, ngetrapake gaya kompresif lan shearing kanggo luwih ngurangi bijih dadi
• Vibrating Screen: A multi-deck vibrating screen classifies the crushed ore. Oversized particles (>25 mm) are recirculated to the cone crusher (forming a closed circuit), while undersized particles pass to the small size ore bin for grinding. This configuration maximizes crushing efficiency and ensures consistent feed size for the mill.

2. Grinding and Classification Section

Grinding and classification work synergistically to liberate manganese minerals from gangue at the microscale. This section employs a closed-circuit grinding circuit to balance fineness and energy efficiency.

• Small Size Ore Bin & Feeder:Bijih sing wis dihancurkan disimpen ing surge bin lan dipasok menyang penggilingan liwat feeder sekrup utawa sabuk, njaga aliran material sing konstan. Iki nyegah kekurangan bahan baku ing penggilingan utawa overloading, ngoptimalake kinetika grinding.
• Ball Mill:Ball mill yaiku wadah silindris sing muter lan setengah kebak bola baja (biasane 20–50 mm ing diameter). Nalika penggilingan muter, bola-bola iki bakal cascade lan nabrak bijih, nyuda iki dadi slurry kanthi partikel
• Spiral Classifier:Sawise penggilingan, slurry diarahkan menyang spiral classifier, sing misahake partikel adhedhasar kecepatan mbethoki. Partikel kasar (>75 μm) dibalekake menyang ball mill kanggo digiling maneh, dene partikel alus (

3. Bagian Beneficiation

Tahap iki nggunakake kombinasi pemisahan magnetik lan pemisahan gravitasi kanggo nyentrake mineral mangan, nggunakake sifat fisik (magnetisme, densitas) kanthi relatif marang gangue.

• Screening Sieve:Saringan penyaringan frekuensi tinggi ngilangake kotoran kasar utawa partikel sing ora digiling saka slurry sing digiling. Langkah iki njamin panganan kanggo separator duwe ukuran partikel sing seragam, ningkatake efisiensi pemisahan.
• High Gradient Magnetic Separator (HGMS):Mineral mangan (contone, manganit, psilomelane) asring nuduhake sifat paramagnetik utawa ferromagnetik. HGMS ngasilake medan magnet intensitas tinggi (>1.5 T) nggunakake matriks kawat ferromagnetik, narik lan misahake mineral mangan magnetik saka gangue non-magnetik (contone, kuarsa, feldspar). Proses iki bisa ngunggahake grade mangan saka 20–30% dadi 45–55%, gumantung saka jinis bijih.
• (Gravitasi Pisah):Kanggo bijih mangan kanthi bedane kepadatan sing signifikan (mineral mangan ~4.5–5.0 g/cm³ vs. gangue ~2.6–3.0 g/cm³), meja goyang digunakake. Meja iki nggunakake gerakan diferensial lan aliran banyu kanggo misahake partikel miturut kepadatan, konsentrasi mineral mangan ing zona konsentrat nalika nolak gangue minangka tailings. Langkah iki utamane efektif kanggo mulihake mineral mangan sing halus sing kelangan nalika pemisahan magnetik.

4. Bagian Pengeringan lan Penanganan Produk

Tahap pungkasan iki ngeproses slurry konsentrat mangan dadi produk kelembapan rendah sing cocog kanggo panyimpenan, transportasi, utawa pemrosesan luwih lanjut.

• Pengental:The manganese concentrate slurry is fed into a lamella or circular thickener, where solid particles settle under gravity. Polymer flocculants are often added to accelerate settling, increasing the slurry’s solids content from ~10–20% to ~50–60%. This reduces the volume of material requiring filtration, lowering operational costs.
• Vacuum Filter:A rotary vacuum filter is used to dewater the thickened concentrate. It employs vacuum pressure to draw water through a filter cloth, producing a filter cake with moisture content
• Concentrate Silo:Koncentrat mangan sing wis dipisahaké banyu disimpen ing silo dhasar con, sing ndhukung pambongkaran lan nyegah akumulasi bahan. Silo iki njamin pasokan konsentrasi sing terus-terusan kanggo muat utawa proses hilir (contone, pelletizing).
• Pompa Slurry & Sirkulasi Air:Pompa slurry berat mindhah slurry abrasif antarane tahap proses, nalika sistem daur ulang banyu njupuk lan nggunakake maneh banyu saka thickeners, filter, lan tailings. Iki nyuda konsumsi banyu tawar nganti >80%, nggawe proses iki lestari kanggo lingkungan.
