Design and Fabrication of the Setup for Resin Sand Reclamation and Investigate the Effects of Different Parameters on the Performance of the Reclamation Process

Abstract

With the increase in use of shell mouldingin variety of applications concept of reclamation of the resin sand is gaining attention. Moreover, sand disposal costs are always on the increase and many foundries are reclaiming their sand for re-use. Present work aims at design and fabrication of the reclamation setup that require less energy consumption, minimal air use and easy to install. The setup consists of electric furnace with rotary cylinder inside it. This setup is capable of performing both dry attrition and thermal reclamation of small quantity of resin sand which helps in increasing the performance of the reclamation process. Reclamation of the reclaimed sand by varying the process parameters like heating temperature at 500 °C, 550 °C, 600 °C and heating duration of 20 min., 25 min. and 30 min. is performed. Investigation of the performance of reclaimed sand obtained from experimental trials is carried out based on the properties of the sand like compressive strength, hardness and loss on ignition. Comparison of properties of mixture of reclaimed sand and resin sand in different proportion is done with the properties of fresh resin sand.
