High Efficiency green sand foundry mixer for Foundry Applications

The machine’s transmission mechanism incorporates advanced circular arc tooth spiral technology, ensuring uniform and thorough mixing. Its compact design minimizes space requirements and simplifies installation. The built-in oil pump in the reducer efficiently lubricates gears and bearings, resulting in low noise, reliable performance, and ease of maintenance. Additionally, the system offers flexible operation, making it a dependable and user-friendly solution for various mixing applications.

Purpose of the Sand Mixer:

This versatile equipment is primarily used for mixing molding sand in foundry workshops. It can efficiently mix various types of sand, including machine molding sand, dry ground sand, self-hardening sand, surface sand, and back sand. Additionally, the mixer is suitable for blending various powdered materials used in industries such as glass, ceramics, and refractories.

Key Features:

• Durable Construction:
  The bottom plate is made from wear-resistant ceramic, ensuring a non-sticky surface for sand. The scraper surface is equipped with cemented carbide blocks for long-lasting durability and easy replacement.
• Advanced Wear-Resistant Components:
  The ring’s inner lining is also constructed with wear-resistant porcelain. The rotor blade’s abrasive surface is welded with tungsten carbide, enhancing its resistance to wear and prolonging its service life.
• Efficient Mixing System:
  The unique “S” shaped scraper turns the sand thoroughly, ensuring full mixing while shortening the unloading time. This increases production efficiency. After mixing, the sand meets optimal performance standards:
  • Water content: 2.8-3.8%
  • Compaction rate: 38±2%
  • Wet compression strength: 0.12-0.2 MPa
  • Temperature: ≤ Room temperature +10℃
  • Permeability: >140
• High-Performance Components:
  The mixer is equipped with a high-performance reducer and alloy steel gear, ensuring reliable lubrication control and continuous operation.
• Convenient Side Discharge:
  The mixer features a quick and clean sand discharge system, allowing for flexible and reliable operation.

  

Applications:

• Foundry Workshops:
  Ideal for mixing clay sand, green sand, self-hardening sand, surface sand, and core sand.
• Industries:
  Also suitable for mixing powdered and granular materials in industries such as glass, ceramics, and refractories.

Conclusion:

The high-efficiency rotor sand mixer is a critical piece of equipment in clay sand production lines, delivering consistent results, high productivity, and long service life. Its adaptability and durability make it a reliable choice for foundries and other industries requiring precise material mixing.
