⊙Product Parameters

⊙Application Field

Spiral sand washer is widely used in various industries, including construction, hydropower, and road building. It effectively cleans and separates soil and impurities from sand and gravel, making it ideal for producing high-quality aggregates for concrete and asphalt. Additionally, it is suitable for washing and classifying materials in sand and gravel plants, prefabricated component factories, and hydropower construction sites. The machine can also be utilized in mineral processing to separate materials and remove contaminants, ensuring clean and reliable output.

⊙Machine Structure and Working Principle

Spiral sand washer consists mainly of a trough-like structure, a spiral blade, and a transmission device. Materials are fed into the washing tank, where the spiral blade rotates through a motor-driven gearbox. The rotation of the spiral blade stirs the material, causing the sand and gravel to roll within the water. This process helps to wash away impurities such as soil and dust. Clean material is lifted by the spiral blade and discharged, while excess water and contaminants are removed through an overflow weir. The machine efficiently handles material cleaning, classification, and dewatering tasks.

⊙Customer case

A client from Australia purchased Olive Technology's double spiral sand washer for their large-scale construction project along the coast. The machine was required to handle high volumes of sand mixed with silt and impurities. After installation, the equipment exceeded their expectations by efficiently processing materials at a rate of 150 tons per hour, achieving both high-quality cleaning and reliable dehydration. The adjustable overflow weir and sealed design significantly improved production efficiency, minimizing downtime for maintenance. The client reported a 20% increase in operational productivity and expressed satisfaction with both the machine’s performance and Olive Technology’s timely technical support.
