1. PEMBUKAAN PAINPOINT DRIVEN

Are you managing sand and gravel extraction with equipment that struggles to keep pace? Operational bottlenecks in material processing directly impact your bottom line through lost production, excessive maintenance, and inconsistent product quality. Cabaran biasa termasuk:

High Downtime from Wear: Constant abrasion from silica sand and aggregate rapidly degrades standard components, membawa kepada kerap, unplanned stops for liner changes or crusher maintenance.
Pengelasan Bahan Tidak Cekap: Inaccurate screening and separation results in offspec product, forcing reprocessing that consumes energy and reduces your marketable yield.
Penjanaan Denda Berlebihan: Overcrushing or improper processing creates an excess of fine particulate, diminishing the volume of highvalue coarse aggregate and creating waste management issues.
Inflexible Production Flow: Fixedconfiguration plants cannot easily adapt to varying feed material hardness or shifts in market demand for different aggregate sizes.

Is your operation sacrificing profitability to these persistent issues? Penyelesaiannya bukan hanya terletak pada mesin, but in a precisionengineered system designed for the specific demands of sand gravel mining.

2. GAMBARAN KESELURUHAN PRODUK

The [Nama Syarikat Anda] HighCapacity Sand & Loji Pemprosesan Kerikil adalah modular, stationary crushing and screening system engineered for highvolume aggregate production. It is designed for operators requiring consistent output of specification sand, pea gravel, and coarse aggregate from pitrun material.

Aliran Kerja Operasi:
1. Pengurangan utama: Pitrun material is fed into a robust primary jaw crusher for initial size reduction.
2. Menghancurkan sekunder & Pemeriksaan: Material is conveyed to a cone crusher for further refinement, then screened to separate coarse aggregate.
3. Pemprosesan tertiari & Mencuci: Remaining material is routed through a vertical shaft impact (Semua orang) crusher for optimal sand shaping and fines generation control, with optional integrated log washers or sand screws for cleaning.

Skop Permohonan & Batasan:
Skop: Ideal for medium to largescale quarry operations producing construction aggregates (concrete/ asphalt), industrial silica sand, and drainage materials. Effective on limestone, granit, and river rock deposits.
Batasan: Not suitable for highly consolidated igneous rock without upstream blasting. Maximum feed size is determined by primary crusher model. Integrated washing requires a consistent water supply and slurry management plan.

6. SENARIO APLIKASI

Regional Aggregate Supplier & Concrete Producer

Cabaran: Needed consistent production of both ASTM C33 concrete sand and multiple coarse aggregate sizes from highly variable pitrun gravel. Existing plant produced excessive fines and required constant manual CSS adjustment.
Penyelesaian: Implementation of our Model SG450 plant featuring the Adaptive Crushing Chamber Automation and MultiFrequency Screening Deck.
Keputusan: Achieved a stabilized yield meeting all spec fractions simultaneously. Penjanaan denda dikurangkan sebanyak 22%. Plant output became predictable, allowing accurate batching forecasts for their concrete division.

Sand Mining Operation

Cabaran: Severe wear costs on tertiary crusher components were eroding margins on specialty silica sand products. Downtime every six weeks for liner replacement was unacceptable.
