Addressing the Core Challenges of Modern Sand & Gravel Processing

Your operation faces relentless pressure: maximizing yield from variable deposits, controlling escalating energy and maintenance costs, and meeting stringent spec requirements—all while minimizing downtime. Inefficient processing directly impacts your bottom line. Are you experiencing inconsistent product gradation leading to premium product loss? Is unscheduled maintenance on aging equipment cutting into production hours? Are you struggling to balance throughput with the rising cost of water, kuasa, and wear parts? The solution lies in precisionengineered equipment designed for the specific demands of commercial sand and gravel extraction.

Gambaran Keseluruhan Produk: Kapasiti Tinggi, Modular Sand Classification & Dewatering System

This system is engineered for the continuous, highvolume separation and dewatering of sand fractions (biasanya 100 mesh to ¼”) from a slurry feed. It optimizes the critical final stages of your wash plant to deliver dry, inspec product directly to stockpile.

Aliran Kerja Operasi:
1. Slurry Infeed: Sandladen slurry from a cyclone or screen is distributed evenly across the full width of the system.
2. DensityBased Separation: A rising current of water fluidizes the sand bed, allowing fine, lowdensity particles to overflow while higherdensity, coarser sand settles.
3. ,Kawalan penggredan: Adjustable weirs and splitter gates enable precise cutpoint control, creating up to three product grades.
4. ,Penyahairan Mekanikal: Settled sand is conveyed up an inclined deck, where gravity and screen vibration remove free surface moisture.
5. ,Stockpile Discharge: Dewatered sand (biasanya 912% kandungan kelembapan) is discharged via conveyor for stockpiling or loadout.

Skop Permohonan: Ideal for medium to largescale sand operations processing bank run or pitrun material. Best suited for materials with a specific gravity consistent with natural silica sands or similar aggregates.

Batasan: Not designed for primary washing of heavily claybound material or for processing gravel larger than 1/2". Feed preparation via scrubbing and screening is a prerequisite for optimal performance.

Senario Aplikasi

[Midwest Aggregate Producer] Cabaran: Needed to replace three aging screw classifiers that could not meet new concrete sand spec fineness modulus consistently, resulting in high recirculating load and pond silt buildup.

Penyelesaian: Installation of a single highcapacity classification system with adjustable splitter gates after the primary screen.
Keputusan: Achieved precise FM control (±0.05), increased total plant throughput by 22%, reduced pond dredging frequency from biannual to every four years.

[Southwestern Construction Materials Company] Cabaran: High fuel costs were eroding margins due to hauling excessive water weight in washed sand; winter freezeups also caused stockpile handling issues.

Penyelesaian: Integration of a dewateringfocused classification system into their existing wash plant circuit.
Keputusan: Reduced average moisture content from 21% ke 10%, calculated annual fuel savings of over $48,000 in hauling costs, eliminated winter processing shutdowns due to frozen stockpiles.
