1. Pembukaan PainPoint Didorong

Every ton of material you process carries hidden costs. Inconsistent feed quality from your pit forces downstream crushers and screens to operate below optimal efficiency, wasting up to 15% of your energy budget. Unplanned downtime from conveyor belt wear or pump cavitation due to uncrushed gravel can cost a midsized operation $8,000 sejam dalam pengeluaran yang hilang. Mengurus a Pesanan Pukal Syarikat Perlombongan Kerikil Pasir introduces further pressure: how do you maintain consistent throughput when a single order can represent 30% of your monthly output? Are your current systems capable of handling the surge in load without sacrificing product specification or increasing your reject rate? The margin between a profitable bulk contract and a lossmaking one often lies in the reliability and capacity of your primary processing equipment.

2. Gambaran Keseluruhan Produk

This solution is a highcapacity, modular wet processing plant specifically engineered for Pesanan Pukal Syarikat Perlombongan Kerikil Pasir fulfillment. It is designed to convert runofmine (ROM) feed into clean, classified sand and aggregate fractions in a single, continuous workflow.

Aliran Kerja Operasi:
1. Suapan & Menggosok: ROM material enters a heavyduty rotary trommel with internal breaker bars. This stage breaks down clay balls and separates oversize (+150mm) material for rejection.
2. Saringan Utama: Material passes over a highfrequency, multideck screen. This separates the 150mm feed into three primary streams: kerikil kasar (+20mm), medium gravel (420mm), dan pasir (4mm).
3. Pengelasan Pasir: The 4mm slurry is pumped to a hydrocyclone cluster. The underflow (pasir kasar) is dewatered on a dewatering screen. The overflow (fines and silt) is sent to a thickener for water recovery.
4. Gravel Washing: The coarse and medium gravel streams pass through a log washer to remove any remaining surface coatings, ensuring a clean product for concrete aggregate specifications.
5. Stok & Pemuatan: Bersih, dewatered products are conveyed to radial stackers for stockpiling. A batch blending system allows for precise mixing of sand and gravel to meet specific Pesanan Pukal Syarikat Perlombongan Kerikil Pasir gradation requirements.

Skop Permohonan: Ideal for processing alluvial deposits, riverbed gravels, and crushed rock fines. Batasan: Tidak sesuai untuk sangat kasar, highsilica content ores without specialized wear liners. Maximum feed moisture content should be below 12% for optimal screening efficiency.
