1. PEMBUKAAN PAINPOINT DRIVEN
Your current sand and gravel extraction process is likely bleeding capital. Data industri menunjukkan bahawa masa henti yang tidak berjadual daripada skrin bergetar konvensional dan penghancur kos agregat loji purata $2,800 sejam dalam pengeluaran yang hilang. Tambahan pula, regulatory pressure on water usage and sediment runoff is increasing compliance costs by 1218% annually for noncompliant operations.
Are you facing declining yield from your existing wet processing plant due to fines accumulation? Is your maintenance budget exceeding 15% of operational expenditure because of abrasive wear on slurry pumps and conveyor belts? Do you need to maintain a consistent 95% product purity while reducing your water consumption footprint by 30% to meet local environmental permits?
The solution lies in a reengineered approach to material handling and classification. Kami Vendor Perlombongan Kerikil Pasir Mampan equipment line is designed to address these specific operational bottlenecks.
2. GAMBARAN KESELURUHAN PRODUK
The Vendor Perlombongan Kerikil Pasir Mampan adalah modular, closedloop processing system designed for dry and wet classification of alluvial deposits. It integrates a highfrequency dewatering screen with a hydrocyclone reclamation unit and a variablefrequency drive (VFD) conveyor system.
Aliran Kerja Operasi:
1. Pengambilan Suapan: Bahan mentah (0150mm) is fed into a vibrating grizzly feeder to scalp oversize (+150mm) bahan.
2. Penghancuran utama & Menggosok: Material passes through a horizontal shaft impactor (HSI) for primary reduction, followed by a rotary scrubber to break down claybound aggregates.
3. Pengelasan: Slurry enters a multistage hydrocyclone cluster. Underflow (pasir) reports to the dewatering screen; melimpah (kelodak/tanah liat) is routed to a thickener.
4. Penyahairan & Menyusun: The dewatering screen produces a moisture content of <8% for immediate stockpiling. The thickener recovers 90% air proses untuk digunakan semula.
5. Pengendalian Tolak: Filtered cake from the thickener is conveyed to a drystack tailings area, eliminating the need for settling ponds.
Skop Permohonan: Suitable for riverbed mining, pit extraction, and manufactured sand production from limestone or granite.
Batasan: Not recommended for materials with >30% clay content without a prewetting stage. Maximum feed size is 150mm.

8. Soalan Lazim
Q: Can this system handle highclay content feed material?
A: ya, hingga 30% kandungan tanah liat. For higher clay, we recommend a prewetting drum scrubber as an addon module. Field data shows the rotary scrubber reduces claybound aggregates by 95% in a 3minute retention time.
Q: Apakah garis masa pemasangan biasa?
A: From order to commissioning, jangkakan 1620 minggu. Ini termasuk 8 minggu untuk fabrikasi, 4 weeks for shipping, dan 48 weeks for site assembly and electrical hookup.
Q: How does the water recycling system affect pump maintenance?
A: The thickener underflow water contains less than 50 ppm suspended solids. This reduces pump impeller wear by 60% compared to untreated pond water. Seal life extends from 6 bulan ke 18 bulan.
Q: What is the ROI on the Premium Package?
A: Berdasarkan a 250 Operasi TPH berjalan 2,000 jam setahun, the water savings ($0.30/ton) and increased yield (8%) generate an annual benefit of $480,000. Payback is typically 3.5 tahun.
Q: Adakah anda menyediakan latihan untuk pengusaha loji?
A: ya. A 3day onsite training program is included with every purchase. This covers PLC operation, screen media changeout, and cyclone apex adjustment. Latihan penyegaran jauh tersedia setiap suku tahun.
Q: What is the maximum particle size for the dewatering screen?
A: The screen deck is designed for a top size of 12mm. Material bersaiz besar (+12mm) must be scalped prior to the dewatering screen to prevent blinding. The primary screen handles this automatically.
Q: Can the system be relocated after installation?
A: ya. The modular design uses bolted connections, tidak dikimpal. A 4person crew can disassemble, pengangkutan, and reassemble the system in 3 minggu. Purata kos penempatan semula $80,000.
