Hydraulic Open-box Sand Making Machine

The hydraulic open-box crusher is an upgraded version of traditional fine crushers (such as cobblestone sand making machines), featuring a hydraulic power-assist system as its core highlight. This equipment operates on the "rock-on-rock" or "rock-on-iron" autogenous crushing principle. It uses hard alloy hammers mounted on a high-speed rotating rotor to shatter the materials, while the fine crushing and shaping are achieved through the rebound against the liner plates and the mutual collisions of the materials within the crushing chamber. Additionally, the discharge particle size can be flexibly controlled by adjusting the gap of the bottom grate bars.

Features

  • _0118_场景图2
    • Hydraulic Quick Cabinet Opening
      Hydraulic cylinder opens the housing with one-touch operation; hammer and liner replacement can be finished within 30 minutes, greatly cutting maintenance downtime (conventional bolt-type opening takes more than half a day).
    • Large Reduction Ratio & One-step Forming
      Large raw stones turn into finished aggregates directly, removing the need for primary jaw crusher and lowering overall production line investment.
    • Superior Particle Shape
      Rock-on-rock crushing delivers well-cubed aggregates meeting standards for high-grade concrete and road construction.
  • _0117_场景图4
    • Excellent Anti-blocking Performance
      Widened crushing chamber prevents blockage for materials with moisture up to 25%, suitable for damp raw materials in rainy seasons.
    • Long Service Life & Wear Resistance
      Thickened body plus high-manganese alloy hammers; inner material lining protects cabinet against abrasion and reduces replacement frequency of wearing parts.
    • Flexible Output Adjustment
      Multiple finished sizes available simply by swapping grate bars with different gaps for diversified production.
