Section<\/th>Details<\/th><\/tr><\/thead>
General explanation<\/td>The double-rotor sand maker is an advanced machine for producing artificial sand with two opposing rotors that convert materials into fine and uniform particles through impact and abrasion. Its double-sided design allows simultaneous crushing from both sides and offers high efficiency in material production lines.<\/td><\/tr>
Technical specifications<\/td>– Production capacity: 100-300 tons per hour (depending on input material size and settings) – Motor power: 150-250 kW (two independent motors for each rotor) – Rotor dimensions: diameter 1.5-2 meters, length 2-3 meters (can be customized) – Input material size: maximum 50-80 mm – Rotor material: wear-resistant manganese steel with Hardox coating<\/td><\/tr>
Benefits and uses<\/td>– Advantages: High efficiency (up to 30% more than single-rotor models), reduced energy consumption, production of materials with ideal cubic shape, long durability against abrasion and impact, easy installation and low-cost maintenance – Applications: Production of sand and gravel for ready-mixed concrete, asphalt, construction industries, stone quarries and river material processing lines<\/td><\/tr>
Installation and maintenance<\/td>Installation on concrete or metal base with automatic lubrication system; periodic inspection of rotors every 1000 hours of operation to replace coatings; compatible with PLC automation systems for precise control.<\/td><\/tr>
Warranty and support<\/td>12-month performance warranty; after-sales service including operator training, spare parts supply, and technical advice by the NovinCSM team.<\/td><\/tr><\/tbody><\/table>

Double-sided sand making machine applications<\/strong><\/h2>

Main:<\/strong> Secondary crushing of soft\/medium rocks to sharp sand (0-6 mm, 70% output), suitable for concrete\/asphalt with <5% return.
Industries:<\/strong> Lime\/clay mines, sand\/gravel production, cement, road construction (5-15 cm crushing to <6 mm).
Types:<\/strong> 4 hammers (low capacity), 6 hammers (high), jacked (hydraulic for easy adjustment).<\/p>

Advantages of double-sided sand making machine<\/strong><\/h2>
  • Two-way (alternate use of both sides, 30% less wear); sharp\/broken output for better adhesion of concrete.<\/li>
  • Wet load OK (unlike rock and rock); easy adjustment of anvil, parts available\/cheap.<\/li>
  • High capacity compared to rabbit (60 vs 25 t\/h); economical for medium-sized mines.<\/li>
  • Iranian production with 6-12 month warranty, 1 day installation.<\/li><\/ul>

    Disadvantages of a double-sided sand maker<\/strong><\/h2>
    • High wear on hard rocks (Mohs >6; need to replace hammer every 3-6 months).<\/li>
    • Sensitive manual\/hydraulic adjustment (irregular output if overload); heavy weight (crane carrying).<\/li>
    • 5% return (requires screen); sensitive to moisture >10% without dryer.<\/li><\/ul>

      Installation and maintenance tips for the double-sided sand maker<\/strong><\/h2>

      Installation:<\/strong> on a concrete base, connected to a feeder\/screen; levelling \u00b10.05 mm (1 day).\u00a0Hydro jack for export\/adjustment.
      Maintenance:<\/strong> hammer\/anvil inspection (every 200 hours), rotor lubrication; replace hammer edge >5 mm. Avoid a large load >15 cm.
      Transportation:<\/strong> maximum 15 tons for trailer (1 unit), 10-ton crane.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
