Product Catalog: HighCapacity Stone Quarry Crushing Plant

1. Pembukaan PainPoint Didorong

Your quarry operation faces three persistent financial drains: unscheduled downtime from crusher jams costing $2,500–$8,000 per hour in lost production, escalating wear parts replacement every 600–900 operating hours, and inconsistent aggregate gradation that triggers contract penalties of 3–7% per load. Pengurus loji melaporkan bahawa 40% of maintenance budgets are consumed by conveyor belt repairs and screen deck changes alone. Engineering contractors struggle to meet tight project deadlines when primary crushing stages bottleneck at 80% penggunaan.

Is your current setup forcing you to choose between throughput and product quality? Are you absorbing 15–20% higher energy costs per ton than industry benchmarks? This catalog addresses those specific operational friction points.

2. Gambaran Keseluruhan Produk

The Loji Penghancur Kuari Batu adalah modular, threestage closedcircuit system designed for continuous hard rock reduction from 800mm feed to 0–40mm finished aggregates.

Aliran Kerja Operasi:
1. Menghancurkan Rahang Utama: Bahan Runofmine (600-800mm) is reduced to 150–200mm via a hydraulic wedgeadjust jaw crusher with 250ton crushing force.
2. Penghancuran Kon Sekunder: Material passes through a 300hp cone crusher with automated tramp iron relief, producing 40–80mm intermediate stock.
3. Tertiary VSI Shaping: Vertical shaft impactor with 55m/s rotor speed generates cubical final product and sand (0–5mm).
4. MultiDeck Screening: Skrin bergetar tripledeck (20x6ft) classify material into four fractions simultaneously.
5. ClosedLoop Recirculation: Oversized material returns via radial stacker conveyor to the secondary crusher, mencapai 95%+ circuit efficiency.

Skop Permohonan: Sesuai untuk granit, basalt, batu kapur, and river gravel with compressive strength up to 350MPa. Not recommended for clayrich or highmoisture (>8%) feed materials.

8. Soalan Lazim

S1: Can this plant process limestone with 5% kandungan silika?
A: ya. The SQC series handles limestone up to 150MPa. For silica above 3%, we recommend the Premium package with ceramic wear liners on the VSI, which extends rotor life from 400 ke 700 jam.

S2: What is the typical commissioning timeline from delivery to first production?
A: With the modular design, commissioning takes 5–7 days for a standard installation. This includes mechanical assembly, sambungan elektrik, dan 8 hours of load testing. Penyediaan tapak (foundation and access roads) is separate and typically requires 2 minggu.

S3: How does the plant handle power fluctuations common in remote quarries?
A: The VFDs on conveyors and the PLC include undervoltage ridethrough capability (turun ke 85% nominal voltage for 2 saat). Untuk tapak dengan kuasa grid yang tidak stabil, we recommend the optional 250kVA synchronous condenser package.

S4: What is the annual maintenance budget I should plan for?
A: berdasarkan 3,000 waktu operasi setahun, budget $85,000–$120,000 for wear parts (pelapik, skrin, tali pinggang) and $18,000–$25,000 for lubricants and filters. The Pro service package covers all labor for scheduled maintenance.

S5: Can I integrate this plant with my existing primary jaw crusher?
A: ya. The plant accepts feed from any crusher producing 200mm minus material. We provide an interface conveyor with adjustable height (3.5–5.0m) and a surge bin with 40ton capacity to buffer feed rate variations.

S6: What is the ROI period for the VFD conveyor upgrade?
A: Data medan daripada 12 installations shows energy savings of $38,000–$52,000 per year at $0.12/kWh. With the $42,000 upgrade cost, payback occurs at 10–14 months. Additional savings from reduced belt wear extend payback benefits.

S7: How do you guarantee the 350 tph throughput for granite?
A: Throughput is tested at our facility using granite with 280MPa compressive strength and 15% kelembapan. We provide a performance bond: if the plant fails to achieve 330 tph average over a 4hour test at your site, kami pulangkan 5% of the purchase price.
