Sand Gravel Mining Wholesaler Specification
H1: HighCapacity Sand and Gravel Classifying Tanks | Precision Separation for Maximum Yield
1. HAPJE NGA PIKA E DIKIMIT
Are inconsistent product specs and lost fines eroding your profit margins? In sand and gravel production, inefficient material classification directly impacts your bottom line. Common operational challenges include:
Product Contamination: Inadequate separation of sand fractions leading to offspec material, causing load rejections and diminishing your brand’s reliability.
Yield Loss: Deri në 15% of valuable fine sand can be lost to settling ponds or waste piles due to imprecise classification, representing significant revenue left unrecovered.
Uji i lartë & Konsumi i Energjisë: Inefficient, highvolume water usage increases pumping costs and complicates water management, while oversized pumps drive unnecessary energy expenses.
Frequent Downtime: Congestion and sand buildup in classifiers require regular shutdowns for manual cleaning and adjustment, reducing available operating hours.
How do you increase the precision of your sand products while simultaneously reducing water usage and recovering more saleable material? The solution lies in moving beyond basic settling pits to engineered hydraulic classification.
2. PËRMBLEDHJE E PRODUKTIT
The Advanced Hydraulic Classifying Tank is a controlledcurrent separation system designed for the highvolume, efficient sorting of sand and fine aggregates by particle size and specific gravity. It replaces or augments traditional methods like screw classifiers or simple settling basins.
Rrjedha e punës operative:
1. Slurry Introduction: A sandwater slurry is evenly distributed across the full width of the tank inlet box.
2. Controlled Settling: As material flows horizontally through the tank, particles settle into multiple collection hoppers based on their settling rate—finer particles travel further, coarser particles settle first.
3. Product Extraction: Precisely adjusted valves on each hopper allow for the continuous extraction of up to four distinct, specgrade sand products (p.sh., coarse concrete sand, fine masonry sand).
4. Overflow Management: Ultrafine silt and clay particles remain suspended, reporting to the effluent overflow for further processing or discharge.
Fusha e Aplikimit & Kufizimet:
Ideale për: Washing plants producing multiple spec sands; sites with variable feed material; operations focused on fines recovery; projects requiring precise cut points between 100 mesh and 1/4".
Kufizimet: Not a dewatering device—extracted sands require further dewatering (p.sh., on a dewatering screen). Primary crushing and scrubbing must be completed upstream.
3. TIPARET THEMELORE
Manifold Feed Distributor | Baza Teknike: Laminar flow engineering | Përfitimi Operacional: Ensures even slurry distribution across the entire tank width, preventing shortcircuiting and ensuring consistent classification across all hoppers. | Ndikimi i ROI: Eliminates product banding, ensuring every ton meets specification and reducing reprocessing.
Modular Hopper Design | Baza Teknike: Discrete settlement zones with independent discharge gates | Përfitimi Operacional: Operators can adjust gate openings to control the cut point and volume of each product fraction in realtime based on feed changes. | Ndikimi i ROI: Maximizes yield by allowing precise tuning for changing market demands or feed stockpile variations.
CorrosionResistant Liners | Baza Teknike: Abrasionresistant steel or polyurethane lining at highwear points | Përfitimi Operacional: Dramatically extends service life in critical wear zones compared to unlined carbon steel, reducing maintenance frequency. | Ndikimi i ROI: Lowers longterm operating costs by extending time between liner replacements by up to 3x.
LowProfile, HighCapacity Design | Baza Teknike: Optimized tank geometry for gravity flow | Përfitimi Operacional: Requires less static head pressure than deep cone classifiers, allowing integration with existing pump systems and reducing overall plant height requirements. | Ndikimi i ROI: Lowers initial installation costs and simplifies retrofit into existing plant layouts.
Fines Recovery Baffle System | Baza Teknike: Hydraulic current control baffles | Përfitimi Operacional: Promotes retention of difficulttocapture 70200 mesh fines within the product hoppers before they report to overflow. | Ndikimi i ROI: Directly increases recoverable product yield by capturing valuable fines previously lost.

6. Skenarët e APLIKIMIT
Concrete Sand Producer Facing Market Expansion Challenge
Sfida: A regional producer needed to separate its single "concrete sand" product into two distinct grades—a coarse ASTM C33 concrete sand and a finer masonry/blend sand—to access new contracts without major plant overhaul.
Zgjidhje: Installation of a Model CFT150 Classifying Tank downstream of their existing wash screen.
Rezultatet: The operation now simultaneously produces two inspec products at a combined rate of 150 TPH. Të dhënat në terren tregojnë a 22% increase in total sales revenue from the same deposit due to premium pricing on the masonry sand fraction.
Alluvial Gravel Pit with High Fines Loss Challenge
Sfida: Significant volumes of profitable fine concrete sand (70100 rrjetë) were being lost to settling ponds due to an overloaded screw classifier system, resulting in wasted resource and high pond dredging costs.
Zgjidhje: Retrofitting a classifying tank as a primary classifier ahead of the existing screws, which were repurposed as dewatering units.
Rezultatet: Recovered an additional 25 TPH of saleable fine sand previously lost. This increased overall plant yield by approximately 12%, paying back the equipment investment in under one season while drastically reducing pond maintenance.
