DESCRIPTION:Dry Vibrating mix is a product range commonly used as refracto
 ry lining of core induction furnaces in foundries. As indicated in their n
 ame\, these products are installed dried\, and the initial strength is onl
 y due to the densification by vibration. In this type of product\, the sha
 pe of the grain\, the granulometry curve and the type of vibration used ha
 ve an impact on the densification. To determine the optimised parameters o
 f our solutions\, the Discrete Element Method seems the easier way to vali
 date or optimise our products and is an alternative to the classic experim
 ental process. \n\nThe first part of the study consists in the characteris
 ation of two different DVM to define as precisely as possible the paramete
 rs of the model. This is the more complex part of the study. The granulome
 try curves\, bulk density\, E modulus\, shapes of the grain are the simple
 st initial parameters. Some more tricky parameters like static response an
 gle\, dynamic response angle\, rolling resistance or adherence need also t
 o be characterised. These parameters are defined by simulating two differe
 nt flow tests coming from Granutools.\n\nWhen the model is defined\, it is
  easy to simulate the densification process\, and analyse the impact of se
 veral parameters in the densification of our products like type of vibrati
 on\, initial loading\, or shape of the grain. \nThis new method offers a n
 ew way to optimise our products and seems a promising way to improve sever
 al types of manufacturing processes in the refractories field.
