What is Sand Recycle Machine?
In traditional sand washing production lines, a large amount of fine sand below 3mm is washed away with wastewater, resulting in serious fine sand loss, low finished sand fineness modulus and uneven gradation. Unprocessed tailings slurry contains a lot of sediment, which cannot be recycled directly, causing massive water resource waste and environmental sediment pollution. Long-term fine sand loss greatly reduces sand output and economic benefits of the plant, while tailings accumulation also increases site occupation and disposal costs.
Our Sand Recycle Machine perfectly solves the above industry pain points. It integrates centrifugal classification, fine sand recovery and vibration dewatering into one system. The high-pressure slurry pump sends tailings wastewater into the hydrocyclone for fine sand separation and concentration. The concentrated fine sand is evenly sprayed onto the vibrating dewatering screen for secondary dehydration and molding. Wastewater and mud impurities are separated and recycled, realizing maximum fine sand resource recovery and green circulating water production, greatly improving finished sand quality and plant profit margin.
Complete Machine Configuration & Core Structural Advantages
1. High-Efficiency Hydrocyclone Centrifugal Classification System
Equipped with high-precision polyurethane hydrocyclone, it generates strong centrifugal force during high-speed slurry rotation. High-density fine sand particles are thrown to the cyclone wall and sink downward for concentration and separation, while low-density silt, clay and wastewater overflow from the top. It accurately screens and recovers 0.16-3mm fine sand particles, thoroughly solving the problem of ultra-fine sand loss in traditional sand washing processes.
2. Wear-Resistant Polyurethane Dewatering Screen
The vibrating screen adopts integral polyurethane screen mesh, which features high wear resistance, anti-clogging and long service life. The high-frequency vibration system realizes rapid dehydration of concentrated fine sand, effectively reducing sand moisture content to below 8%-12%. The uniform vibration avoids material accumulation and screen hole blockage, ensuring continuous and stable fine sand molding and discharging.
3. High-Pressure Wear-Resistant Slurry Pump
Supporting dedicated slurry pump adopts thickened wear-resistant impeller and casing, which can stably transport high-concentration muddy slurry without clogging. It provides stable high-pressure feeding power for the cyclone, ensuring uniform slurry concentration and consistent separation effect. The pump body is resistant to slurry erosion, with low failure rate and long continuous operation cycle.
4. Integrated Compact Modular Structure
The whole machine integrates feeding, classification, recovery, dewatering and water collection systems, with compact layout and small floor space. No complex installation and civil engineering is required, and it can be directly connected with the sand washer discharge port. The modular design is convenient for transportation, on-site assembly and daily maintenance, saving plant construction and layout costs.
5. Adjustable Feeding & Separating Precision
Equipped with adjustable flow control device and variable frequency vibration system. Users can adjust slurry feeding pressure, vibration frequency and discharging speed according to on-site sand properties and output requirements. It flexibly controls fine sand recovery particle size and dewatering effect, adapting to different artificial sand and natural sand processing standards.
6. Fully Sealed Anti-Sediment Water Circulation System
The matched water tank and overflow pipeline adopt anti-sedimentation design, which avoids mud accumulation and pipeline blockage. The separated clean circulating water can be directly reused for sand washing operation, realizing zero wastewater discharge. The closed-loop water circulation greatly reduces water resource consumption and meets environmental protection production standards.
Core Product Advantages of Sand Recycle Machine
1. High Fine Sand Recovery Rate, Maximize Resource Utilization
The professional cyclone centrifugal separation technology effectively captures lost 0.16-3mm fine sand, with fine sand recovery rate up to 90%+. It recovers a large amount of wasted fine sand resources, effectively increases total sand output of the production line, optimizes sand gradation, and greatly improves the economic benefits of the sand plant.
2. Optimize Finished Sand Quality & Stable Gradation
It solves the problems of coarse finished sand, unreasonable gradation and low stone powder content caused by fine sand loss in traditional sand washing. The recovered fine sand is fully dehydrated with uniform particle size, which optimizes the overall fineness modulus of finished sand, improves sand compactness and construction performance, and enhances market competitiveness of finished aggregate.
3. Energy-Saving & Water-Saving, Green Environmental Protection
The closed circulating water system realizes 100% wastewater reuse, greatly reducing on-site water consumption. The low-power matching motor reduces invalid energy consumption. It avoids tailings slurry discharge and sediment accumulation pollution, solves the environmental protection problems of sand washing plants, and realizes green and low-carbon production.
4. Anti-Blockage & Stable Continuous Operation
The polyurethane screen mesh and anti-clogging cyclone structure effectively prevent slurry and fine sand blockage. The high-frequency vibration self-cleaning design ensures unobstructed material operation. The whole machine can operate stably for 24 hours continuously, with low failure rate and high production continuity, suitable for large-scale long-term sand production lines.
5. Low Operating Cost & Less Maintenance
The main vulnerable parts are made of high wear-resistant polyurethane materials, with long service life and low replacement frequency. The integrated structure has few mechanical failures and simple daily maintenance. It saves a lot of later maintenance costs and manual management costs for sand and gravel plants.
6. Wide Adaptability & Easy Matching
It can be perfectly matched with wheel sand washers and spiral sand washers, applicable to artificial crushed sand, natural river sand and various aggregate washing production lines. It supports customized processing capacity from 30-300TPH, meeting the transformation and upgrading needs of small, medium and large sand plants.
Working Principle & Production Flow of Sand Recycle Machine
Working Principle
The Sand Recycle Machine adopts hydrocyclone centrifugal classification + high-frequency vibration dewatering dual technology. The tailings muddy wastewater discharged from the sand washer is pumped into the hydrocyclone by a high-pressure slurry pump. Under strong centrifugal force, high-density fine sand particles are separated and concentrated, sinking to the cyclone bottom and uniformly sprayed onto the vibrating dewatering screen.
Through high-frequency vibration screening, fine sand is rapidly dehydrated to form dry finished sand. Low-density silt, clay and sewage overflow from the cyclone top into the circulating water tank, which can be reused for sand washing operation. The whole process realizes automatic fine sand recovery, tailings purification and water recycling, completing efficient and environmentally friendly fine sand recovery production.
