This book presents the design and development of an aluminium can crushing machine, in order to optimise the recycling line. For the implementation of this machine it was necessary to use some devices, pneumatic and electro-pneumatic; electrical devices; Programmable Logic Controller (PLC) and mechanical mechanisms. With the implementation of this equipment, it was observed a greater facility for the automation of the process, obtaining better results in the point of view of safety in addition to the proportional increase of recycling. Thus, this machine contributes to the reduction of efforts for people working with recyclable materials and consequently will influence the form of example for future work.
