Facing Rising Operational Costs and Inconsistent Material Quality?
Your current sand and gravel mining operation is likely grappling with three critical issues: escalating extraction costs per ton (lart 1522% industrywide over the past 24 muaj), declining uniformity in aggregate gradation leading to concrete mix rejection rates of 47%, and increasing regulatory pressure on environmental compliance. Plant managers report that unplanned downtime from substandard crushing and screening equipment accounts for 1218% of lost production hours annually. Engineering contractors face the additional burden of sourcing reliable, costeffective machinery from a fragmented supply chain.
Is your existing equipment partner delivering the throughput consistency and total cost of ownership (TCO) required to maintain margins in a competitive market? How can you secure a manufacturing partner that balances highcapacity output with strict adherence to Chinese GB/T standards for construction aggregates?

FAQ
P: How does your equipment comply with Chinese GB/T standards for construction aggregates?
A: Our plants are designed to produce material meeting GB/T 146842011 (rërë) and GB/T 146852011 (zhavorr). We provide a certificate of analysis with each shipment confirming gradation, indeksi i flakiness, and fines modulus.
P: Cila është koha tipike e prirjes për një 350 tph bimë?
A: Koha standarde e prodhimit është 90120 days from receipt of 30% paradhënie. Kjo përfshin fabrikimin, montim, dhe testimi në fabrikë. Dorëzimi i përshpejtuar (60 ditë) është në dispozicion për një shtesë 10% shtesë.
P: Can the plant handle material with high moisture content (p.sh., river sand with 15% lagështia)?
A: po. Our standard design includes a grizzly feeder to scalp fines. Për materialet që tejkalojnë 12% lagështia, we recommend the washing system option (SGM350TW) which includes a dewatering screen to achieve <12% moisture in the final product.
P: Sa është kostoja e pritur vjetore e mirëmbajtjes si përqindje e vlerës së pajisjes?
A: Bazuar në të dhënat në terren nga 50 instalimet, annual maintenance cost (excluding power) averages 35% of the initial equipment cost. This includes wear parts, lubrifikantët, and minor repairs. Major overhauls are typically required every 18,00020,000 orët e punës.
P: Do you provide onsite training for plant operators?
A: po. Our commissioning package includes 3 days of handson training for up to 4 operatorët. We provide a detailed operations manual and video guides. Remote refresher training is available via video call.
P: How does your pricing compare to European or American manufacturers?
A: Our equipment is typically 3545% lower in initial capital cost compared to equivalent European brands (p.sh., Rrënjët, Sandvik). Total cost of ownership over 5 vjet është 2030% lower due to lower spare parts costs and faster local service response.
P: What is your warranty policy on structural components?
A: We offer a 24month warranty on structural steel frames and a 12month warranty on all mechanical and electrical components (excluding wear parts). Warranty covers manufacturing defects and premature failure under normal operating conditions.
