The Spiron is pleased to announce that the United States Patent and Trademark Office (USPTO) has officially granted Patent No. US 12,508,593 B1 for our proprietary technology: “Automatic Size Adjusting and Damage Preventing Glass Grinder and Method of Grinding Glass Materials.”

The patent recognizes a novel mechanical solution designed to optimize the efficiency and durability of glass recycling equipment.

Key Technical Specifications:

The patented device utilizes a specialized crushing assembly and control mechanism to ensure consistent output and hardware longevity:

  • Optimized Jaw Configuration: The system features a fixed vertical crushing jaw paired with a movable jaw designed with two distinct slopes. This geometry facilitates progressive material reduction and improves the grip on varied input sizes.
  • Multi-Directional Eccentric Motion: An eccentric rotating mechanism is mechanically coupled to the movable jaw. This setup allows for movement in two different directions relative to the fixed jaw, enhancing the grinding efficiency and ensuring a more uniform particle size distribution.
  • Structural Protection and Adjustment: A dedicated adjusting mechanism is integrated to hold and move the movable jaw dynamically. This mechanism serves as a safeguard against structural overstress, preventing damage when the system encounters uncrushable materials or experiences excessive mechanical loads.

Practical Applications:

For the glass recycling industry, this technology provides several direct operational advantages:

  • Precision Output: Enhanced control over the final grain size of the recycled glass.
  • Reduced Maintenance: The damage-prevention mechanism significantly reduces downtime and the need for frequent part replacements.
  • Energy Efficiency: The mechanical advantage provided by the dual-slope jaw and eccentric drive reduces the torque required for the crushing process.

This achievement marks a significant milestone in The Spiron’s commitment to developing high-performance, sustainable engineering solutions for the circular economy.
