1. PEMBUKAAN PAINPOINT DRIVEN

Are you an importer or plant manager facing rejected shipments due to inconsistent aggregate gradation? Each noncompliant container of sand or gravel can cost your operation between $2,500 dan $8,000 dalam bayaran demurrage, rescreening costs, and contractual penalties. Do your current testing protocols fail to catch moisture content spikes that cause downstream concrete mix failures? Can you verify that your imported material meets ASTM C33 or EN 12620 specifications before it reaches your stockpile? The gap between supplier claims and actual delivered quality often results in 35% material waste and unplanned downtime for your crushing and screening circuits. How can you implement a testing regime that protects your capital equipment and your client contracts?

2. GAMBARAN KESELURUHAN PRODUK

The Sand Gravel Mining Importers Testing system is a modular, onsite quality verification platform designed for bulk material receiving terminals and processing plants. This equipment integrates sampling, analisis saiz zarah, and moisture detection into a single workflow.

Aliran Kerja Operasi:
1. Automated Sampling: A crossbelt or vertical drop sampler extracts a representative 50100 kg sample from the incoming conveyor or truck discharge.
2. Saringan Utama: The sample passes through a grizzly or vibrating screen to separate oversize (+75mm) material for immediate rejection.
3. Gradation Analysis: A multideck sieve shaker (4 ke 8 pecahan) provides realtime particle size distribution data, comparing results against your specified import standards.
4. Kelembapan & Fines Measurement: A nearinfrared (NIR) sensor or lossondrying unit calculates moisture content and the percentage of minus 200 denda mesh.
5. Pengelogan Data & Pelaporan: Results are automatically uploaded to your inventory management system with a pass/fail status and batch certificate.

Skop Permohonan: Ideal for river sand, crushed stone fines, and marinedredged gravel. Batasan: Not suitable for cohesive claybound materials or oversized boulders exceeding 150mm without precrushing.
