Analyzing reasons for breakage of ring die

1.Domestic material which made of the ring die is unstable and irregular and it has regional interior stresses with ring die (material suppliers should compensate for the loss).

2.High porosity of ring die for pellet mill (according to customer’s request) give rise to declining of hardness and toughness of ring die. 


 

3.Thickness of ring die is so thin (without release period requested by customer) that hardness of ring die for pellet mill is lowering. 

4.During the operation of ring die for pellet mill, ring die is broken by the compress force from hard objects( for example, bearing balls which falling into the pellet making chamber) .

5.Ring die is in eccentric statement and has uneven stress with fixtures during the installment of ring die for pellet mill, (located at the concentric position with assembly of press roller)  that cause ring die for pellet mill bear unidirectional vibration constantly. 

Ring die is pellet mill an important component that it’s just like heart for human being. Quality of ring die greatly influences the output per hour, power consumption, qualities of products and so on.  Excellent ring die ensure regular and steady production.
