In order to favourite subsequent operations of the lead battery breaking and separation, small pieces are more easily transportable and treatable.
The hammer mill for lead battery recycling is of type hammer: the charge is supplied from above by means of a conveyor belt, the discharge takes place from the bottom and is transported by a screw conveyor. A grid fixed to the base of the hammer mill acts as a sieve for retaining the separation of larger pieces that have not been milled. The armor plates are fixed on the inner walls of the mill and have the function to protect the mill from the violent impact of the battery pieces.
The armored front wall is hinged and can be easily opened. This configuration simplifies the operations of internal inspection and maintenance, such as the replacement of the hammers or the elements of the grid.
The mechanical and chemical stress which acts on the various parts of the hammer mill during the lead battery recycling requires an opportune choice of the construction material: for the realization of the hammers steel has been used, able to resist to stress corrosion cracking. Furthermore, an opportune cycle of thermal treatments guarantees a higher impact resistance (resilience) and superficial hardness. The motor shaft is realized in quenched steel and designed to resist to use and fatigue. The internal plates are realized in stainless steel. The shaft is driven by an electric motor and the transmission occurs by means of a belt and pulleys.
The motor of the hammer mill can be activated via the monitoring system developed on PC, both in manual and automatic mode. In particular, in manual mode start / stop is controlled by the user, while in automatic start / stop will be managed by the control software developed on PLC. In both cases, the boot is regulated by a soft-starter and the actual supply will only be present if the disconnector placed on board the machine is not in the service position.
