OCAMPO RAMIREZ, Arturo et al. Design of a ball mill for recycling brake pads tractor-trucks using the method of bond. Rev Cie Téc Agr [online]. 2015, vol.24, n.3, pp.45-51. ISSN 2071-0054.

Currently available in public transportation the need to constantly replace brake Pasta factor mainly due to wear and for safety reasons. This paper proposes to create the basis for the overall design of a prototype machine capable of re- use and reduce the size of the brake pastas public transport that are out of use to be used as the main agent in a slurry. This paste is used as insulation material in construction, covering walls and ceilings, also in the development of solid base paving streets. To implement this proposal using the method of Bond blocks in order to estimate the initial size of the mill and the necessary power through the creation of a BM- Crush numerical program, thus avoiding pilots to build mills where this is possible. The main results obtained are the general methodology for calculating the mechanical power and the necessary dimensions of the mill based on any changes in the initial conditions of operation, as well as the distribution of the grinding media and their sizing. Critical velocity is estimated on this basis established the optimal speed at which to rotate the ball mill.
