Main features - New crusher in a week - Capacity increased by 5-10% - Specific wear rate (g/t) reduced - Specific power consumption (kWh/t) reduced - Wear parts last longer - Less downtime - Less maintenance required - Maintenance facilitated Since FLSmidth first launched the EV hammer impact crusher in the mid fifties, design improvements have continuously been introduced while its basic concept has remained the same. overhaul of rotor and grate. The new parts can be fitted during the scheduled stoppage while rotor and grate are dismantled. Many of the improvements have been based on the day-to-day...

The new design of hammer rotor and outlet grate assembly overcomes these disadvantages to a large extent and increases operational time between scheduled maintenance stoppages. The introduction of the hammer bolt handling hydraulic tool and the hammer handling rack makes hammer rotor maintenance safer and much more efficient. The new hammer rotor design does not include a flywheel. The safety mechanism is incorporated in the coupling assembly. The mass of the now superfluous flywheel is mostly placed in the hammer rotor itself where it is applied more directly to the crushing process. When installing...

Hydraulic opening of crusher housing Another feature that reduces downtime and makes servicing of the crusher safer is the hydraulic opening of the crusherhousing. Installing two hydraulic cylinders, appertaining brackets and a set of hinges enables the crusher to be opened within 5 - 10 minutes. Hydraulic tool for changing of hammers A hollow hydraulic cylinder placed in a rigid frame is provided to handle the hammer bolts when turning or changing hammers. A mobile hydraulic power unit supplies the hydraulic pressure to operate the cylinder. The power unit has a pressure/flow control system...
