Automatic wood classifying system to produce renewable fuels from construction waste

Automatic wood classifying system was developed to sort wood only from construction waste such as vinyl, plastic, and wood in order to produce renewable fuels. Automatic classifying processes are performed in the following order, step1: crushing, step2: analysis in the form of a mixture with water, step3: collection and transporting of floating materials, step4: classifying float materials with blower system. To classify a mixture of wood that are classified by air wind volume and classifying wood reliability can be varied depending on air wind volume. And, vinyl and plastic are difficult to classify due to increase in weight with water during the processes. Therefore, the number of times the experiment was repeated to get the optimal air volume to control it. In this experiment, the air wind volume is very important part.
