Figure 20 presents the results of tensile strength tests of the molding sand made on the basis of sand matrix, prepared with fresh sand and recovered mechanical reclaim in various proportions. Based on the results obtained, it was found that the addition of 25% and 50% did not worsen the tensile strength of the sand, but actually improved it.

Firstly, the sand from the mechanical reclamation plant will pass through a cleaning tower which basically removes any metallic particles prior to entry into the furnace. The furnace itself is a fluidised bed design with a gas and air mixture providing the fluidising medium and igniting on the sand bed surface via pilot gas nozzles.
