Hydrocone Piston Applications<\/strong><\/h2>

Primary Function:<\/strong>
Adjusts the closed side setting (CSS 8\u201348\u202fmm) and provides overload protection in hydrocone crushers, maintaining the balance of the main shaft.<\/p>

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

  • Mining in Kenya (granite crushing)<\/p><\/li>

  • Cement plants (Nairobi \/ Mombasa)<\/p><\/li>

  • Construction (sand production)<\/p><\/li><\/ul>

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

    • Single Piston:<\/strong> CSS adjustment, e.g., Sandvik QH models<\/p><\/li>

    • Double Piston:<\/strong> Overload protection for heavy-duty models<\/p><\/li><\/ul>

      Advantages of Hydrocone Piston<\/strong><\/h2>

      • Rapid CSS Adjustment:<\/strong> 1\u20132\u202fminutes for single piston; automatic overload protection<\/p><\/li>

      • Efficiency Improvement:<\/strong> Up to 30% higher productivity due to reduced downtime<\/p><\/li>

      • Durability:<\/strong> 1,000\u20132,000\u202ft service life with ductile cast iron<\/p><\/li>

      • Market Compatibility:<\/strong> Fits Novincsm, Delta, and Sandvik hydrocone models in Kenya<\/p><\/li>

      • Easy Installation:<\/strong> Hydraulic setup in 30\u202fminutes; operating pressure up to 200\u202fbar<\/p><\/li><\/ul>

        Limitations of Hydrocone Piston<\/strong><\/h2>

        • Sensitive to oil temperatures above 150\u202f\u00b0C (requires cooling)<\/p><\/li>

        • Heavy weight requiring crane handling<\/p><\/li>

        • Used units may have worn cylinders (check tolerance \u00b10.03\u202fmm)<\/p><\/li><\/ul>

          Installation & Maintenance Guidelines<\/strong><\/h2>

          Installation:<\/strong><\/p>

          • Mount in main frame; connect hydraulic system; alignment tolerance \u00b10.05\u202fmm (1\u20132\u202fhours)<\/p><\/li><\/ul>

            Maintenance:<\/strong><\/p>

            • Lubricate every 200\u202fhours; monitor pressure (100\u2013200\u202fbar); replace seals if wear >5\u202fmm<\/p><\/li><\/ul>

              Transport:<\/strong><\/p>

              • Maximum 150\u202fkg per trailer (single unit); 5\u2011ton crane required<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
