Equipment Composition of Artificial Sand Production Line

The artificial sand production line is specialized equipment engineered for the manufacture of construction-grade sand and aggregates. It achieves a 50% reduction in energy consumption compared to traditional sand-making machines. This system processes materials such as rock, gravel, and river pebbles into various particle sizes that meet construction sand specifications. The resulting artificial sand features uniform particle size and high compressive strength, outperforming both natural sand and ordinary hammer crushers. The produced sand aligns more closely with construction requirements, thereby enhancing overall build quality.

1. Equipment Configuration of the Artificial Sand Production Line

In the operation of the sand production line, large stones are evenly fed into the jaw crusher via a vibrating feeder from the silo for coarse crushing. The coarsely crushed material is then transported by belt conveyor to either a cone crusher or an impact crusher for medium crushing. Subsequently, the crushed stone is conveyed by belt to the vibrating screen for classification. Finished sand (undersize) is moved by belt conveyor to the sand washing machine for cleaning and finally deposited onto the finished product pile via another belt conveyor. Oversize stones are sent by belt conveyor to the vertical shaft impact crusher (sand-making machine) for fine crushing. The finely crushed material is returned to the vibrating screen by belt conveyor for re-screening, thereby establishing a closed-circuit system with multiple recirculation cycles.

2. The Role of Sand Washing Machines in Artificial Sand Production Lines

The sand washing machine is primarily utilized during the screening and washing stages of sand production lines. In traditional wet processing technologies for artificial sand, spiral sand washing machines are commonly used for washing and dewatering; however, controlling fine sand loss remains challenging. Implementing a fine sand recovery machine effectively minimizes fine sand loss and reduces stone powder content in tailwater. This solution addresses issues related to high fineness of finished sand and low stone powder content within artificial aggregate processing systems.

3. Key Features of Sand Washers in Artificial Sand Production Lines

1) Effectively reduces fine sand loss, maintaining it within 5%-10%, thereby enhancing production efficiency.

2) The vibrating screen employs polyurethane mesh, offering extended service life and resistance to clogging.

3) Fine particles are fully recovered, reducing the workload on the sedimentation tank and lowering its cleaning costs.

4) The travel device is lined with polyurethane, enhancing the service life of the entire unit and ensuring smooth slurry concentration and liquid clarification.

5) It increases the proportion of fine particle materials in the total discharge by 85%, offering unparalleled technical and economic advantages over other equipment.

6) The storage time for fine materials is reduced, allowing them to be directly transferred and supplied to the market.

7) Customized solutions can be designed according to specific user requirements.
