Элсийг оновчтой болгох & Gravel Recovery: Addressing the High Cost of Fines Loss and Inefficient Classification

Are you struggling to balance product specification with maximum yield? In sand and gravel mining, inefficient classification directly impacts profitability. Нийтлэг бэрхшээлүүд орно:

Торгуулийн орлогоо алдсан: Шалтгаална, хамаарна 15% of marketable fine sand (50150 шүүр) can be lost to settling ponds, representing significant wasted inventory.
Тогтворгүй бүтээгдэхүүний зэрэглэл: Fluctuating feed material leads to offspec product, causing load rejections at the plant and eroding customer trust.
High Water and Energy Consumption: Traditional classifying tanks and screw washers are often waterintensive and can have high recirculating load demands, increasing pumping costs.
Frequent Manual Adjustment: Operators constantly monitor and adjust weirs or water valves based on visual discharge, leading to variability and operator dependency.
Хязгаарлагдмал өргөтгөх чадвар & Хөлийн мөр: Expanding production with conventional systems requires substantial space and duplicate systems, complicating plant design.

How do you capture every ton of saleable material while ensuring precise gradation control, all within a compact footprint? The solution lies in advanced hydraulic classification technology.

Бүтээгдэхүүний тойм: The HighEfficiency Hydraulic Classifier

The modern hydraulic classifier is a purposebuilt system for the continuous, wet classification of sand and gravel particles by size and density. It replaces or augments traditional classifying tanks, screw washers, and hydrocyclones in many applications.

Үйл ажиллагааны ажлын урсгал:
1. Сларри танилцуулга: A controlled sand/water slurry feed enters the unit's distribution manifold.
2. Fluidized Bed Classification: Rising current water creates a fluidized bed; particles settle against this upward flow based on their settling velocity (a function of size, дур хэмжээ, and shape).
3. Нарийвчилсан тусгаарлалт: Finer, slowersettling particles are carried over the weir as overflow (бүтээгдэхүүн), while coarser, fastersettling particles report to the underflow discharge.
4. .Dual Product Streams: The system continuously discharges two products: a controlled fine product (халих) and a dewatered coarse product (underflow), each with specific cut points.

Хэрэглээний хамрах хүрээ & Хувьсгал:
Тохиромжтой: Primary classification of dredged or pitrun material; producing concrete sand; separating fine sand from coarse sand; removing lightweight contaminants; recovering fines from pond return.
Хувьсгал: Not a dewatering device—underflow requires further dewatering via screen or cyclone. Optimal feed size is typically below ¼ inch (6мм). Performance is dependent on consistent feed density and rate.
