產品描述

TJLM Laboratory liquid nitrogen cryo planetary ball mill is a specially designed grinding equipment, for some special requirements, needed to be ground in liquid nitrogen and low temperature or ultra low temperature. It’s a necessary equipment for fine grinding, mixing, sample preparation, high-tech materials and new product development and small batch production. Laboratory liquid nitrogen cryo planetary ball mill has the advantages of small size, simple structure, high efficiency, low noise, easy operation and so on. It is an ideal equipment for scientific research institutes, colleges and universities and enterprises to obtain samples ( four samples can be obtained simultaneously ). You can match special low temperature vacuum ball mills, and samples can be ground in low temperature and vacuum condition. Special intensified mechanical structure has higher efficiency, greater performance, minimum size of grinding products available to 0.1µm (1.0×10~4mm) even nanoscale.

 

Application Area

  • Material specialty:

Laboratory liquid nitrogen cryo planetary ball mill alloying, preparation of nano materials.

  • Biological Specialty:

Small or medium amount of animal and plant samples

  • Other Specialty:

Thermosensitive and thermoplastic sample crushing

 

FUNCITON PRINCIPLE

TJLM Laboratory liquid nitrogen cryo planetary ball mill adopts self-contained liquid nitrogen jar, and use the pressure of itself to inject the liquid nitrogen into the jacket layer of grinding jar. Samples in the grinding jar and ball mill are cooled by liquid nitrogen in the jacket layer of grinding jar. During the operation of the instrument, relying on the high impact energy of the grinding ball and the friction between the ball and grinding jar to crush samples, the grinding jar, the sample, and the grinding ball rotate on a rotating disk.

At the beginning of grinding, the rotating force of the grinding jar is mainly produced through the friction force produced by grinding ball friction in the jar wall to crush samples; when running at a certain time, the strong centrifugal force generated by the support plate can separate the sample on the inner wall of the grinding jar and the grinding ball, and grinding ball along the inner wall of the grinding jar impact samples with continuous high speed, reducing sample size by impact force.

Because laboratory liquid nitrogen cryo planetary ball mill adopts a unique liquid nitrogen delivery system, in the process of rotating machine, the refrigerant will absorb the heat generated by the high speed rotating ball mill, resulting in a persistent low temperature environment at ball mill that loaded with materials and balls. Circulating liquid nitrogen directly discharged into the air, each jar has a separate valve to control the flow rate of liquid nitrogen.

DESIGN CHARACTERISTICS

  • Maintaining a constant rotation ratio of the support plate by a specified drive belt.
  • Microprocessor control speed
  • Digital display of the actual speed of the planetary disk
  • Optional forward and reverse rotation
  • Programmed control of grinding time and cooling time
  • Grinding chamber safety lock with interrupt monitoring
  • The pressure lever makes the cover of the grinding cavity open quickly.
  • Clean internal circulation liquid nitrogen supply system
  • Convenient liquid nitrogen flow control can control the liquid nitrogen intake of a single grinding jar
  • electronically controlled three-phase motor (1.5kW) and drive with frequency conversion and durable cryogenic and lubricated bearing.
  • Universal host voltage (200-400V)
  • Ventilated grinding chamber
  • Impact resistance and
