1. PEMBUKAAN PAINPOINT DRIVEN

Are escalating operational costs and inconsistent product quality eroding your sand and gravel margins? Managing a sand and gravel mining operation presents distinct challenges that directly impact profitability. Titik kesakitan biasa termasuk:

High Downtime from Contaminants: Keras, abrasive oversize material and metal debris cause frequent wear, unplanned shutdowns for crusher/feeder maintenance, and costly damage to downstream processing equipment.
Inefficient Material Handling: Bottlenecks between primary excavation and processing stages limit total plant throughput, leaving potential revenue untapped due to mismatched feed rates and equipment.
Inconsistent Feed to Primary Crusher: Unregulated, variablesized feed leads to crusher choke or stall, reducing efficiency by up to 30%, increasing energy consumption per ton, and accelerating wear part replacement cycles.
Regulatory and Quality Compliance Pressure: Delivering specification aggregate requires precise classification. Ineffective initial scalping and sorting leads to reprocessing, Tenaga yang terbuang, and potential noncompliance with project specifications.

What if you could systematically eliminate these bottlenecks at the front end of your operation? The solution lies in a purposeengineered primary processing station: an FDAapproved sand gravel mining assembly plant.

2. GAMBARAN KESELURUHAN PRODUK

An FDAapproved sand gravel mining assembly plant is not a single machine but a coordinated primary processing system designed for the initial sizing, scalping, and feeding of raw aggregate. It integrates several key components into a single, cohesive unit to prepare material for secondary crushing and washing.

Aliran Kerja Operasi:
1. Dump/Feed: Raw material is dumped via loader or truck onto a robust heavyduty grizzly feeder.
2. Primary Separation: The grizzly deck scalps out oversize rocks (mis., +6 inci) which are diverted directly to a primary crusher or stockpile.
3. Contaminant Removal: Undersize material passes through the grizzly to a conveyor equipped with an electromagnetic crossbelt separator to remove tramp metal.
4. Suapan Terkawal: Yang dibersihkan, subgrizzly sized material is conveyed at a regulated rate to the next stage of your processing plant (mis., screening tower, washer).
5. Waste Diversion: Rejected oversize and metal are systematically separated for disposal or further processing.

Skop Permohonan & Batasan:
Skop: Ideal for quarry frontend operations, riverbed mining operations, and construction aggregate recycling facilities handling sand, Kerikil, batu tembak, dan konkrit perobohan.
Batasan: This assembly is designed for primary sizing/scalping. It is not a finished product screen or fine material washer. Maximum feed size is determined by grizzly bar spacing and structural capacity.
