Is a kind of special grinding ball mill, which is designed to load the ball mill jars under the environment with the heat preservation cover, and input liquid nitrogen gas into the grinding space continuously to absorb the heat generated by high-speed rotating of the ball mill jars, so that the ball mill jars loaded with materials and balls are always kept in a certain low temperature environment. It is a necessary device for fine powder grinding, mixing, small sample preparation, new product development and small batch production of high-technology materials. Tencan planetary ball mill has advantages such as volume, complete functions, high efficiency and low noise. It is an ideal powder milling equipment for scientific research centers, universities and colleges, and enterprise laboratories to obtain research samples. You may get four samples at one time for each grinding, you can also use this model to get powder samples under the vacuum environment if it is equipped with vacuum ball mill jars for grinding.
Working temperature of ball mill jar : -40 ℃ ~20 ℃
Consumption volume of liquid nitrogen per hour (0-10 C) : 4-5 liters / hour
Ball mill Dimensions : 460*660*720mm
Net weight : about 80kgs
Available sizes of liquid nitrogen container : 30L or 50L
Liquid nitrogen planetary ball mill has four working positions which can be loaded with two or four mill jars on one turntable. When the turntable rotates, the jar axis makes planetary movements at high speed, the balls and materials inside the jars are impacted strongly in high speed movement, and materials are eventually ground into fine powder. Various kinds of different materials can be ground by means of dry or wet grinding method. The smallest granularity of output powder can be reached to 0.1μm or nano scale powder.
Liquid nitrogen planetary ball mill is designed with semi circular appearance, which is punched and formed by high-precision die, elegant, high and stable. All machine parts is made of numerical control machining, the planetary disc is casting to be formed in a whole part and the transmission gears are made of special materials to ensure smooth operation of the equipment at high speed. Tightening device of the mill jars is easily operated, convenient, safe and reliable. As a result of low temperature ball milling, application scope of one material has been expanded, so that some materials which can not be ground (temperature rising causes quality change and deformation) can be realized to be ground. Liquid nitrogen planetary ball mill has advantages of fast rotating speed, high energy, high efficiency and fineness.is designed with semi circular appearance, which is punched and formed by high-precision die, elegant, high and stable.
