FOR LEAD BATTERY RECYCLING

The hammer crusher for lead battery recycling crushes the entire battery into smaller pieces so that they can be manipulated better in the

subsequent processing.

At the beginning of the lead battery breaking and separation process the batteries are loaded from above by means of a conveyor belt into the hammer crusher and fall into the upper casing where they are crushed by the hammers and the fragments are dischar-ged from the lower casing on a vibrating feeder. The frame of the hammer crusher is internally protected with reinforced plates in order to resist to the impact of the batteries.

Under the lower casing the user must prepare a vibrating feeder for the collection and transport of the fragments towards the next tape. The hammers are mounted on a motor shaft that rotates at about 800 revolutions/min.

The mechanical and chemical stress which acts on the various parts of the hammer crusher 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 super�cial 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 takes place by means of a pulley system.

The motor of the hammer crusher 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.
