7-Meter Spiral Sand Washer \u2013 Applications<\/strong><\/h3>

Primary Function:<\/strong>
Washing and separating mud\/slime from sand after screening and before drying; producing clean sand with moisture <5%.<\/p>

Industries:<\/strong><\/p>

  • Sand\/gravel mines<\/p><\/li>

  • Concrete production<\/p><\/li>

  • Asphalt and cement plants<\/p><\/li>

  • Glass\/tile production (improving quality of river\/rock sand)<\/p><\/li><\/ul>

    Types:<\/strong><\/p>

    • Single spiral (common for 7-meter models)<\/p><\/li>

    • Double spiral (higher capacity)<\/p><\/li><\/ul>

      Advantages:<\/strong><\/p>

      • Precise washing with minimal loss (<5%)<\/p><\/li>

      • Improves concrete adhesion (reduces cement consumption by 10\u201315%) and durability of materials<\/p><\/li>

      • Low energy\/water consumption (\u224820 m\u00b3\/h) and reduced pollution<\/p><\/li>

      • Polyurethane blades: 30% longer lifespan than standard steel<\/p><\/li>

      • Uniform texture and brighter color<\/p><\/li>

      • Flexible integration with modern NovinCSM lines (after Cubit\/Hydrocone)<\/p><\/li>

      • Economical: locally produced, OEM quality, easy installation (1\u20132 days)<\/p><\/li><\/ul>

        Disadvantages:<\/strong><\/p>

        • Moderate water consumption (requires recirculation system for savings)<\/p><\/li>

        • Wear parts: blade replacement every 6\u201312 months under heavy use<\/p><\/li>

        • Medium weight (requires crane handling); sensitive to overload (efficiency drops above 60 t\/h)<\/p><\/li>

        • Used\/old units may show corrosion (check 6 mm plates)<\/p><\/li><\/ul>

          Installation & Maintenance Notes:<\/strong><\/p>

          • Install after screening; maintain 18\u00b0 spiral slope<\/p><\/li>

          • Connect to water pump (2\u20133 bar); concrete base; leveling tolerance \u00b10.05 mm (installation: 1\u20132 days)<\/p><\/li>

          • Periodic washing (every 200 hours); monitor blade wear (>5 mm replace)<\/p><\/li>

          • Avoid acidic materials<\/p><\/li>

          • Lubricate PM400\/Russian gearbox regularly<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
