1. PEMBUKAAN PAINPOINT DRIVEN

Managing a custom sand and gravel operation means balancing precise product specifications with relentless cost control. Bahan suapan yang tidak konsisten, fluctuating market demands, and stringent environmental regulations create persistent bottlenecks. Adakah anda menghadapi cabaran khusus ini?

Pemprosesan Tidak Fleksibel: Your static plant struggles to adapt between producing concrete sand, pasir mason, and various gravel aggregates, leading to missed bids and underutilized reserves.
Kos Pengendalian Semula yang Tinggi: Multiple transfer points, excessive wheel loader use for stockpile management, and doublehandling of material directly erode your profit margin. Industry data indicates material rehandling can account for 1525% daripada kos operasi.
Pencemaran Produk & Ketidakkonsistenan: Inefficient separation of fines, organics, or deleterious materials results in offspec product, penolakan pelanggan, and the costly reprocessing of entire stockpiles.
mengizinkan & Footprint Limitations: Expanding your pit run or installing a new fixed plant involves lengthy permits and capital commitment. You need a production solution that maximizes yield within a constrained or temporary footprint.

Soalan sentral menjadi: how can you increase operational flexibility and product purity while systematically reducing costperton for your custom blends?

2. GAMBARAN KESELURUHAN PRODUK

A Loji Cuci Modular is a semiportable, configurable processing system designed for the precise washing, klasifikasi, and dewatering of sand and gravel. It enables operators to produce multiple specification aggregates from variable feed material without the permanence or high capital cost of a fixed plant.

Aliran Kerja Operasi:
1. Suapan & PraSkrining: Pitrun material is conveyed into an integrated scalping screen to remove oversize rock (+2” or +3”) which is diverted to a crusher circuit or waste pile.
2. Mencuci & Pergeseran: The screened material enters a log washer or scrubber barrel (Bergantung pada model) where claybound agglomerates are broken apart through mechanical action.
3. Klasifikasi saiz: Material is distributed to vibrating screens for precise separation into desired aggregate sizes (mis., 57 batu, 8 Kerikil).
4. Mencuci Pasir & Penyahairan: Fine material (4 mesh) is routed to a cyclone(s) and a dewatering screen or fine material washer to produce lowmoisture, saleable concrete or mason sand.
5. Stok: Sized aggregates and sand are conveyed to separate stockpiles via radial conveyors, minimizing loader rehandling.

Skop Permohonan & Batasan:
Skop: Ideal for custom aggregate producers, contract crushing operations, site development projects requiring onsite processing, and operations feeding concrete/asphalt plants with specific material needs. Effective on deposits with moderate clay contamination.
Batasan: Not a substitute for primary crushing; feed size must be precontrolled. Throughput is typically capped below that of the largest fixed plants (generally ranging from 75 350 Tph). Highly abrasive feeds will increase wear component costs.
