This process is the oldest core and mold making technology that Sand reclamation GIESSEREILEXIKON.COM,The actual reclamation consists of a peeling or impact process which removes all adhesions from the sand grain to the best possible extent. For this purpose, the used mono or mixed sand is prepared in various process combinations. Following the reclamation process, the sand grain is separated.Coated Sand Kailin Foundry,The shell process of the ceramic foundry sand is of high production efficiency. The casting dimensional accuracy and the castings finish are exceptional. The used sand is easy to recycle, which greatly reduces the emission of solid wastes. The environmental benefits of this process are also remarkable.

  • Sand reclamation for chemically bonded sand systems

    The ultimate in sand reclamation has to be thermal, whereby 100% of all binder and other organic material is removed. The sand is generally better quality than when it was first bought. Typically a thermal unit will run on gas or electric and operate at temperatures of between 600C and 750C depending on the type of binder used.Equipments for Shell Sand Preparation, Liquid Resin Sand,Ganesh resin sand coating plant is a specially designed plant working on a warm coating process.
