Experimental verification of the energetic model of the dry mechanical reclamation process

Dańko R.

Archives of Foundry Engineering

2008

Vol. 8, iss. 1

31-36

The experimental results of the dry mechanical reclamation process, which constituted the bases for the verification of the energetic model of this process, developed by the author on the grounds of the Rittinger’s deterministic hypothesis of the crushing process, are presented in the paper. Used foundry sands with bentonite, with water-glass from the floster technology and used sands with furan FL 105 resin were used in the reclamation tests. In the mechanical and mechanical-cryogenic reclamation a wide range of time variations and reclamation conditions influencing intensity of the reclamation process – covering all possible parameters used in industrial devices - were applied. The developed theoretical model constitutes a new tool allowing selecting optimal times for the reclamation treatment of the given spent foundry sand at the assumed process intensity realized in rotor reclaimers - with leaves or rods as grinding elements mounted horizontally on the rotor axis.
