Spiral Ore Washer | Ore Washing & Desliming Equipment
Hengcheng Spiral Ore Washer, also known as a spiral sand washer or spiral washing machine, is designed for washing and desliming clay-containing ores, sand and gravel. It uses mechanical agitation and water washing to remove clay, mud and surface impurities before screening, classification or mineral separation.
What Is a Spiral Ore Washer?
A spiral ore washer is a mineral washing machine used to clean and prepare raw materials before downstream processing. It is particularly suitable for materials containing clay, mud and other unwanted impurities that need to be removed before further processing.
The machine can also be used for washing coarse sand, gravel and other materials. Depending on the application, it can help improve material cleanliness and prepare the feed for subsequent screening, classification or mineral separation.
How Does a Spiral Ore Washer Work?
Raw material enters the washing tank from the feed end and is continuously agitated and scrubbed by the rotating spiral mechanism. The mechanical action helps loosen clay, mud and other impurities attached to the mineral particles.
During the washing process, lighter clay, silt and unwanted fine materials are suspended in water and carried away with the washing water, while the heavier and cleaner material is conveyed toward the discharge end. The washing intensity and operating conditions can be selected according to the material characteristics and required washing result.
Applications and Suitable Materials
The spiral ore washer is widely used for ore washing, desliming, clay removal and sand and gravel cleaning. It can be used as part of mineral processing plants as well as independent material washing systems.
Typical applications include gold-bearing alluvial ore, placer ore, tin ore, tungsten ore, manganese ore, iron ore, chrome ore, sand and gravel. It is especially useful when the feed contains clay, mud, dust or other surface impurities that may affect subsequent screening or separation.
The equipment can be integrated with trommel scrubbers, trommel screens, vibrating screens, hydrocyclones, spiral classifiers and gravity separation equipment according to the requirements of the processing plant.

Spiral Ore Washer in Mineral Processing Plants
In a mineral processing plant, the washing stage is normally used as a pretreatment process before screening, classification and mineral separation. Removing clay and unwanted impurities can help prepare the material for more effective downstream processing.
Hengcheng can integrate the spiral ore washer with other mineral processing equipment to develop a complete processing solution. Depending on the project, a typical plant may include feeding, crushing, washing, screening, classification and gravity or other mineral separation equipment.
Jiangxi Hengcheng Mining Equipment Co., Ltd. is a manufacturer and supplier of mineral processing equipment and complete mineral processing plant solutions in Jiangxi, China. Our equipment is used for processing gold, tin, tungsten, tantalum-niobium, chrome, manganese, iron and other minerals.

Frequently Asked Questions
Q: What is the smallest gold particle size this concentrator can recover?
A: It can recover gold particles as fine as 0.004mm, with a recovery rate of approximately 97% for this size fraction.
Q: How often do I need to clean out the concentrate?
A: The cleaning-up cycle is typically 1–4 hours for vein gold and 2–6 hours for placer gold, depending on the grade of your ore.
Q: Does this machine require chemicals?
A: No. The centrifugal concentrator uses only water and electricity. It is a completely physical separation process with zero chemical pollution.
Q: Can I use this concentrator for tailings re-processing?
A: Yes. It is widely used to recover fine gold from old tailings, grinding circuit discharges, and flotation concentrates where fine gold has not been fully captured.
