One mistake can ruin the entire chain: Feeding errors double the washing system's consumption

In the production lines artificial sand, especially washing sand and gravel hills, the process feed for washing system plays a key role. Not only is it an intermediate step in bringing materials into the washing machine, the feeding device also directly affects the cleaning efficiency, water consumption rate and wear and tear of the subsequent processing equipment.

Why is feeding the washing system important?

In the sand washing process, it is not only the water that is important. It is the perfect coordination between the sand flow and the water flow. Uneven, too fast or uncontrolled feeding can cause:

• Loss of control over sand/water ratio → reduced washing efficiency
• Overloaded material → blockage, equipment wear
• Sand not washed clean → Products do not meet construction standards
• Consuming more water than necessary → increased wastewater treatment costs

Therefore, an intelligent and precise feeding system is a prerequisite for optimizing operations. Saving resources and increasing the quality of finished products.

Terex's dedicated feeder design for washing systems – The complete solution

Feeding the washing system Terex (FM, AggreSand series…) are specially designed to handle sand and gravel mixed with impurities, rocks mixed with clay, sludge. This is the top choice among artificial sand washing stations in Vietnam today.

Outstanding technical features of Terex feeders

• The feeding hopper integrates a manually adjustable inclined grid, flexible according to the material flow.
• The blades and mesh bars are self-cleaning, reducing jams and minimizing maintenance.
• Super heavy duty steel frame, reinforced to operate in harsh conditions such as mountainous mining areas and open pit mines.
• Optional electric or hydraulic drive. Suitable for many terrain conditions and power sources at the construction site.
• Pre-screen removes material >100mm. Helps protect washer and pump system from clogging.
• Quick disassembly, convenient transportation in 20 feet container. Save on logistics and installation costs at the construction site.
• Self-adjusting kickstand. Allows for easy installation even on uneven terrain.
• Rubber rims are abrasion resistant, increasing equipment life – especially important when washing sand mixed with clay and sharp gravel.

High applicability in artificial sand washing line and circulating water treatment

Terex feeders are often combined with washing systems such as:

• Terex FM Sand Washer (Fine Material Washer)
• Water treatment system – sludge press, circulating sedimentation tank

This combination creates a closed chain from feeding - washing - water recovery, helping:
✅ Increase efficiency of separating mud, soil, and organic matter from sand
✅ Reduces fine material loss
✅ Optimize operating and maintenance costs of wastewater systems

Practical application in Vietnam – Evidence from real projects

Nguyen Vinh has implemented more successfully 35 artificial sand and hill gravel washing lines in the provinces: Quang Ninh, Ha Nam, Binh Phuoc, Tay Ninh, Gia Lai...
Each line is individually designed, depending on:

• Raw material type: hill sand, gravel, weathered limestone...
• Input size
• Power required
• Output product target (construction sand, concrete sand, TCVN standard artificial sand...)

Actual results show:
🔹 Reduce water consumption up to 25 – 40% thanks to stable material supply
🔹 Stable output sand quality, meeting standard 9205:2012
🔹 Equipment maintenance time is significantly reduced
