  • Device for recycling molding sand
    Patent number: 9061288
    Abstract: A device for recycling molding sand, the device containing a base; a vibratory reclaimer; a pneumatic cascade classifier serially connected at its upper section to the vibratory reclaimer; and at least two generators of vibrations. The vibratory reclaimer contains: a vertical column, the vertical column being hollow and cylindrical in shape, having an axis of rotation, and a side wall with at least one pour-out hole, wherein the pour-out hole is connected with a transport trough, and the transport trough is rigidly mounted and rises in a spiral fashion along the side wall and at a top end passes through a channel extending to a feeding screw for feeding recycled molding the to the pneumatic cascade classifier.

  • Method for making foundry moulds and cores
    Patent number: 4326578
    Abstract: A method for making foundry moulds and cores where after preparation of the moulds and cores having a sand composition of a low strength up to 0.03 MPa, a cooling medium is introduced into the mould cavity, preferably liquid nitrogen, in an amount to provide hardening of only the surface layer of a required sufficient to reproduce the shape of the mould cavity.
