There is an incorrect cognition that the fineness of powder which is produced by dolomite Raymond mill is affected by the machine’s grinding roll and ring. This idea may push the customers to excessively pursue the good quality of these parts.
As a matter of fact, the powder fineness depends on the classifier and the blower of this machine. The grinding roll and ring belong to the quick-wear parts. That is to say, these two parts will play an important part in the equipment’s service life rather than the final powder size. There are several kinds of raw materials when producing the grinding ring. One belongs to the 65Mn. The grinding ring of this material has high hardness and high wear resistance. Besides, it is magnetic. Therefore, it is usually used in the processing powder which requires the removal of iron. Another raw material is Mn13. The grind ring of this material has received the treatment of water toughening. After being treated like this , the ring has high strength of extension and plasticity. It is nonmagnetic, too. Therefore, it has the ability to resist more impact load.
