Product Introduction:
Tungsten carbide grinding jars, is also known as cemented carbide grinding jars, consists of wolfram carbide and cobalt which is famous for its super high hardness. Therefore, the tungsten carbide grinding jars, which is made of tungsten carbide material, is of good  hardness and abrasion resistance.The powder which is
 used for planetary ball mill can be in good crushing and do not pollute samples,and can meet the requirements on the hardness, wear resistance and comminuted that the ordinary grinding jars cannot do.
Working Principle:
As the necessary accessory of the planetary ball mill, during planetary ball mill grinding the powder, grinding jars, which is fill with balls and samples, grinding the balls and materials with the high speed. By the way of friction, impact and shear, the walls of ball mill jar will produce intense energy to achieve very good  crushing effect. The grinding jar is the container which provides space for completing grinding the powder.
Characteristics:
Tungsten carbide is with high hardness, good wear resistance, strength and toughness, anti-high temperature and corrosion, especially it is with the great advantage of high hardness and good wear resistance. 
Tungsten carbide will not out of shape even if in the 500℃,and is still with high hardness in 1000℃.
