A Spiral sandvasker—also known as a screw sand washing machine—is a heavy-duty mineral processing equipment used to clean, classify, and dewater sand and gravel. Designed with a long helical blade rotating inside a water-filled tank, it separates impurities from sand through friction, sedimentation, and mechanical agitation.
Its central focus is to present a professional overview of performance parameters, product advantages, operational logic, and long-term development trends—ensuring the content aligns with high-value search intent and reader expectations in global markets.
A well-engineered Spiral Sand Washer integrates mechanical reliability with optimized washing efficiency. The following table outlines typical technical parameters widely referenced in industrial applications:
| Parameter | Typisk område / beskrivelse |
|---|---|
| Spiral diameter | 500–1500 mm |
| Spirallengde | 5000–12000 mm |
| Capacity | 20–350 tons/hour depending on model |
| Motor Power | 7.5–30 kW |
| Rotation Speed | 21–35 r/min |
| Vannforbruk | Justerbar basert på materialkvalitet |
| Tank Design | Sveiset kraftig ståltank |
| Utslippsmetode | Overløp for finstoff, bunnutslipp for renset sand |
| Påføringsmaterialer | Elvesand, maskinlaget sand, grus, malmfiner |
| Core Functions | Rengjøring, gradering, fjerning av urenheter, avvanning |
These parameters influence washing quality, energy consumption, loss rate of fine sand, and the machine’s ability to operate in harsh environments such as mining, aggregate plants, and large construction production lines.
Several structural and mechanical benefits contribute to the rising popularity of Spiral Sand Washers:
The machine operates at a relatively low speed, minimizing wear on the spiral blade and tank. This controlled motion lowers maintenance frequency compared with high-speed water washing systems.
Because sedimentation is gravity-driven, the Spiral Sand Washer provides a consistent method for separating undesired silt, clay, and organic matter from finished sand.
The spiral design ensures sand particles remain within the tank while impurities overflow. Advanced versions integrate deep-water tanks to reduce fine sand wastage.
Whether dealing with coarse aggregates or fine machine-made sand, the adjustable water flow and rotational speed allow precision control.
De lukkede vannkretsene muliggjør resirkulering, og reduserer miljøpåvirkning og vannforbruk på anleggsnivå.
Sand kommer inn i vasketanken gjennom en matesjakt.
The spiral blade rotates, stirring and agitating the material.
Impurities float and overflow, leaving the tank.
Clean sand sinks to the bottom and is pushed upward along the blade.
Dewatered sand discharges through the outlet.
Dette systemet bruker friksjon og tyngdekraft i stedet for voldsomme vannstråler, noe som sikrer stabilitet og konsekvent materialhåndtering.
Oppretthold et stabilt fundament for å hindre vibrasjoner.
Bekreft vanninntakstrykk og dreneringsevne.
Still maskinen i en liten stigning for å optimalisere sedimenteringen.
Ensure the feed is evenly distributed to avoid material overload.
Monitor water turbidity to maintain washing quality.
Juster rotasjonshastigheten basert på slaminnholdet i den rå sanden.
Prevent foreign objects from entering the tank.
Planlegg smøring av lagre og drivkomponenter.
Inspiser spiralbladene for slitasje hver 500. driftstime.
Rengjør tanken regelmessig for å forhindre opphopning av sediment.
Skift tetninger når lekkasjen øker.
Sørg for at motortemperaturen holder seg innenfor sikre grenser.
Den langsommere rotasjonshastigheten og fortykkede materialer fører til redusert mekanisk stress og lengre driftssykluser.
Spiral systems handle clay-rich feed more effectively due to deeper agitation and sedimentation effects.
The gravity-assisted classification naturally reduces power requirements.
Fine particles remain inside the tank, preventing economic loss and improving the final grading index.
Fremtidige systemer vil inkludere sensorer for å overvåke vannturbiditet, bladbelastning og motorstatus for å forbedre effektiviteten.
Combined washing and recovery units will become common in machine-made sand production lines.
Vanngjenvinning i lukket krets og løsninger med redusert avfall vil forme neste generasjon vaskesystemer.
Etter hvert som den globale infrastrukturen utvides, vil konsekvent tilførsel av høykvalitetssand forbli avgjørende, og drive kontinuerlig innovasjon.
EN: Capacity selection depends on raw material type, desired cleanliness, and downstream processing requirements. For a medium-scale sand plant, models producing 80–150 tons/hour are common. High-capacity sites typically choose dual-spiral configurations reaching up to 300 tons/hour. Evaluating mud content and feed size distribution ensures proper model selection.
EN: Water flow rate, spiral rotational speed, sedimentation distance, and raw material cleanliness all influence the final quality. If the feed contains excessive clay, pre-screening or soaking may be required to achieve optimal washing performance. Regular tank cleaning also maintains classification stability.
