Product Overview & Core Advantages
The Sand Washing and Dewatering Integrated Machine is a high-efficiency integrated equipment independently developed by Shandong Hengtai Intelligent Manufacturing, aiming at the requirements of washing, dewatering and fine sand recovery in modern sand and gravel production lines across Africa, Southeast Asia, South Asia, South America, Middle East, and Central Asia.
Integrating the functions of sand washing, desliming, dewatering and fine sand recovery into one unit, the equipment effectively solves the problems of high moisture content of finished products, serious fine sand loss and water resource waste in traditional sand washing processes. With stable operation and compact structure, it occupies a small floor area. The moisture content of finished sand can be stably controlled at ≤10%, and the fine sand recovery rate is as high as 85%–95%. It is widely used in manufactured sand production lines, highway, hydropower projects, construction sand processing and tailings recovery.

Tailings Recovery & Recycling
Pain Point: Waste tailings contain valuable fine sand, environmental concerns with wastewater Solution: Cyclone separation recovers 0.16-3mm fines from tailings pond Result: Additional revenue stream from waste material, reduced environmental impact Recommended: ZDT31 series for large tailings recovery operations
Technical Deep Dive: How Integrated Sand Washing System Works
3-Stage Process
1. Sand Washing Stage
Raw sand enters the washing tank where impellers create strong turbulence to remove clay, mud, and impurities. The washing intensity is adjustable based on material contamination level.
2. Cyclone Separation
The mortar mixture (sand + water) is pumped to high-efficiency cyclones that use centrifugal force to separate fine sand particles (0.16-3mm) from wastewater. The recovered fine sand is returned to the dewatering screen.
3. Dewatering Stage
High-frequency vibration screen (typically 16-25 Hz) rapidly removes free water from sand surface. The polyurethane screen panels with 0.5mm slots allow water passage while retaining sand, achieving final moisture ≤10%.
4. Water Recycling System
Wastewater from dewatering screen flows to settling tank where solids settle and clarified water is pumped back to washing stage. Achieves 80-90% water recycling rate, reducing fresh water consumption to 0.5-1 m³ per ton of sand processed.

Frequently Asked Questions (FAQ)
Q1: How much fine sand can be recovered and what is the moisture content of final product?
Our sand washing and dewatering integrated machine achieves fine sand recovery rate of 85-95% for particles sized 0.16-3mm, significantly reducing waste. The high-frequency dewatering screen ensures final sand moisture content ≤10%, making transportation and storage easier compared to traditional sand washers that typically output 15-20% moisture.
Q2: Can this machine work in remote areas with limited water supply?
Yes, the integrated design includes a water recycling system that allows 80-90% of process water to be reused. This makes it ideal for operations in water-scarce regions like parts of Africa, Middle East, and Central Asia. The closed-loop system also minimizes environmental impact and reduces operating costs by lowering water consumption.
Q3: What is the difference between this integrated machine and traditional separate sand washing equipment?
Traditional setups require separate sand washer, dewatering screen, and fine sand recovery units (3 machines), resulting in complex installation and higher maintenance. Our integrated machine combines all three functions in one compact unit: washing, dewatering, and fine sand recovery. This reduces floor space by 40%, simplifies maintenance with single-point management, and lowers total investment cost by 30-40% while achieving better sand quality.
Q4: How do you support installation for sand washing plants in overseas markets?
We provide complete technical documentation including foundation drawings, pipeline layout diagrams, and electrical schematics in English/Spanish. Our support includes: (1) Remote video guidance for mechanical installation and commissioning; (2) On-site engineer dispatch available for complex installations; (3) Operator training on equipment operation and daily maintenance; (4) Long-term spare parts supply for cyclones, screens, and pumps with delivery to Africa, Southeast Asia, South America, and Middle East within 7-15 days.
