Detail & Parts
Product Features
The Liquid Nitrogen Cryogenic Grinding Machine with Screw Feeder boasts several innovative features that enhance its performance and usability:
- One-Piece Design: The crusher host, collection part, feeding mechanism, liquid nitrogen connection part, and electronic control panel are integrated into a single unit. The chassis is made of 304 stainless steel, ensuring durability and aesthetic appeal.
- Flexible Liquid Nitrogen System: The system can use either a foot-operated or electric liquid nitrogen pump, catering to different processing needs. An optional intelligent liquid nitrogen pump offers a more precise and convenient liquid nitrogen input method.
- High-Speed Pulverization: The mainframe utilizes advanced technology from China and Taiwan, featuring a no-sieve wind selection structure that enhances both fineness and uniformity. The operating voltage and current are digitally displayed for easy monitoring.
- Independent Controls: Each part of the machine is equipped with individual control switches, allowing for adjustable feeding speeds and overload protection to safeguard the motor. An emergency stop button further ensures safety.
- Improved Sealing: The new customized PTFE low-temperature resistant sealing ring significantly reduces breakage, enhancing durability and lowering consumable costs. The collector bag can be washed or replaced as needed.
- Secondary Use of Liquid Nitrogen: A small fan and ventilation holes in the chassis facilitate the secondary use of vaporized liquid nitrogen to cool the crusher motor, extending its operating life.
- Versatile Feeding Mechanism: The screw feeder is mounted on a slide, allowing easy dismantling and adjustment to suit different feed sizes. A manual feeding interface is also available for small sample processing.
- Dual-Use Capability: The grinding machine can function as a standalone ultra-fine micro-grinder, providing additional utility and enhancing cost-effectiveness.
Working Principle
The Liquid Nitrogen Cryogenic Grinding Machine with Screw Feeder operates through a sophisticated process that ensures efficient and effective pulverization:
- Feeding and Cooling: Raw materials are fed into the grinding machine through a screw feeder, which can be adjusted for speed. Simultaneously, liquid nitrogen is pumped into the grinding machine, directly freezing the raw materials and cooling the crushing chamber.
- High-Speed Crushing: The frozen materials are subjected to high-speed rotation by blades, resulting in impact, collision, shearing, and friction. This combination of forces achieves ultra-fine pulverization.
- Cyclone Collection: The crushed materials and vaporized liquid nitrogen are brought into a collecting tank via a fineness control structure. The fine powder is collected in a bag, while the vaporized nitrogen is discharged through a cyclone separator.
- Closed-Circuit Circulation: The system forms a closed-circuit circulation, maximizing energy utilization and reducing energy consumption. The chilling source can be adjusted to minus 196 degrees, optimizing the pulverization temperature for different materials.
Product Advantages
The Liquid Nitrogen Cryogenic Grinding Machine with Screw Feeder offers several distinct advantages:
- Enhanced Brittle Effect: Direct contact with liquid nitrogen and continuous low-temperature freezing enhance the brittle effect of raw materials, improving the overall crushing efficiency.
- Uniform and Controllable Feeding: The adjustable-speed screw feeding method ensures uniform and controllable feeding, making batch processing more efficient.
- User-Friendly Liquid Nitrogen Control: The liquid nitrogen input is managed via a dial ball valve, with quantified output for ease of use.
- Improved Durability: The low-temperature resistant PTFE rubber sealing ring significantly reduces breakage, enhancing the machine's smoothness and lowering maintenance costs.
- Versatile Application: The machine is suitable for a wide range of materials, from plastics and rubber to organic foods, making it a versatile tool for various industries.
- Cost-Effective: By maximizing energy utilization and reducing consumable costs, the grinding machine offers a high return on investment.
This comprehensive and detailed introduction highlights the advanced features and benefits of the Liquid Nitrogen Cryogenic Grinding Machine with Screw Feeder, making it an indispensable tool for industries requiring fine material processing.
