Sand Washing Machine‌

Henan Liming Heavy Industry Science & Technology Co., Ltd.‌, a pioneer in mining and aggregate processing solutions, introduces its advanced ‌Sand Washing Machine‌—a high-performance system engineered to deliver superior cleaning, dewatering, and grading of sand and aggregates. Designed for durability and efficiency, Liming’s Sand Washing Machine ensures the removal of impurities (clay, dust, and organic matter) while enhancing the quality of end products for construction, mining, and industrial applications. Combining robust design, intelligent automation, and water-saving technology, this machine is ideal for quarries, concrete plants, and recycling facilities seeking to optimize material value and comply with environmental standards.

Product Overview

Liming’s ‌Sand Washing Machine‌ is a state-of-the-art solution for refining sand and fine aggregates. Built to handle demanding workloads, it features a modular design with high-efficiency screw or wheel bucket configurations, depending on the model. Whether processing natural sand, crushed stone, or recycled materials, this machine ensures precise particle size distribution and low moisture content in the final product. Its corrosion-resistant components and adaptable operation make it a cornerstone for industries requiring high-purity sand for concrete, asphalt, glass, and specialty applications.

Key Features

1. High-Efficiency Cleaning
   • Dual Screw or Wheel Bucket Design: Aggressively removes impurities and recovers fine particles (up to 0.075 mm).
   • Adjustable overflow weirs and water flow control optimize cleaning intensity based on material type.
2. Water & Energy Savings
   • Closed-loop water recycling systems reduce freshwater consumption by up to 80%.
   • Energy-efficient motors and optimized hydraulic systems minimize power usage.
3. Durable Construction
   • Wear-resistant materials (high-chromium steel screws, polyurethane liners) extend service life in abrasive conditions.
   • Reinforced frames and corrosion-proof coatings withstand harsh environments.
4. Intelligent Control
   • PLC Automation: Monitors and adjusts parameters like water pressure, screw speed, and feed rate in real time.
   • Fault detection systems alert operators to blockages or mechanical issues.
5. Low Maintenance
   • Modular components enable quick replacement of wear parts (screws, liners, bearings).
   • Centralized grease lubrication systems reduce manual maintenance efforts.
6. Environmental Compliance
   • Sludge dewatering units separate solids for easy disposal, minimizing wastewater discharge.
   • Dust suppression systems ensure clean, safe operation.
