1. PEMBUKAAN PAINPOINT DRIVEN

Kos operasi yang semakin meningkat dan masa henti yang tidak menentu menghakis margin keuntungan pasir dan kerikil anda? Cabaran industri biasa termasuk:
Pakai tinggi & Kos penyelenggaraan: Abrasive materials rapidly degrade crusher liners, skrin, dan komponen pam, membawa kepada penggantian bahagian yang kerap dan pemberhentian yang tidak dirancang.
Pengelasan Bahan Tidak Cekap: Pemisahan saiz zarah yang tidak konsisten menghasilkan produk offspec, pemprosesan semula yang mahal, and lost revenue from premium aggregate grades.
Penjanaan Denda Berlebihan: Overcrushing in primary and secondary stages creates an oversupply of lowvalue fines, diminishing the yield of highvalue concrete and asphalt sand.
Penggunaan Tenaga Tinggi & Buruh: Inefficient plant layout and manually intensive processes, like feeder regulation and belt monitoring, drive up power costs and require constant operator intervention.
Water Management Complexity: Ineffective slurry handling and dewatering systems lead to water recycling issues, sediment pond overflows, and potential environmental compliance risks.

Is your operation equipped to transform these cost centers into controlled, predictable processes? The right core processing equipment is not an expense but a direct lever for profitability.

2. GAMBARAN KESELURUHAN PRODUK: SAND CLASSIFICATION AND DEWATERING SYSTEM

This sand classification and dewatering system is engineered for the precise washing, saiz, and moisture reduction of sand products in sand gravel mining operations. It is a closedloop solution designed to maximize product value and minimize water consumption.

Aliran Kerja Operasi:
1. Suapan & Pengedaran: Slurry from a wash screen or attritioner is evenly distributed into the system’s feed box.
2. Klasifikasi Hidraulik: Material enters a rising current cyclone or hydraulic classifier, separating sand particles by size and specific gravity.
3. Deck Dewatering: Classified sand is discharged onto a highfrequency dewatering screen, where vibration forces remove surface moisture.
4. Stok & Kitar Semula Air: Onspec dewatered sand is conveyed to stockpile, while effluent water is channeled to a clarifier for recycling.

Skop Permohonan & Batasan:
Skop: Ideal for producing concrete sand, pasir batu, specialty sands, and glass sand from natural deposits or crushed rock. Effective for operations processing 50 ke 500 tons per hour of sand feed.
Batasan: Not a substitute for primary washing or scrubbing of heavily claybound material. Feed slurry consistency must be controlled for optimal classification. Requires a consistent water supply and complementary settling pond or clarifier system.

6. SENARIO APLIKASI

Loji Pengeluaran Pasir Konkrit

Challenge A Midwest producer struggled with inconsistent gradation yielding only ~65% ASTM C33compliant concrete sand from their deposit; the remainder was downgraded as fill material at significant revenue loss.
Solution Implementation of a Model SC150 Sand Classification System with precision hydraulic classifiers replaced their outdated rake classifier system.
Results Within one month of commissioning:
Production of spec concrete sand increased to over 92%.
Fines loss was reduced by twothirds.
Annualized revenue increase exceeded $280k based on increased premium product volume.
