Keestrack to introduce new R5e impact crusher, first on show in the America at Conexpo 2023

The completely newly designed R5e impactor of Keestrack is a full electric plug-in. It also has a plug-out connection to power additional equipment. The impactor used in aggregate production, recycling, quarrying and mining can be powered via mains connection, or via any gen set unit, in case there is no connection to the grid available.

The 61 sT (55t) equipped R5e with a capacity up to 440 sT/h (400 t/h) is very mobile and can be transported in one piece, even equipped in closed circuit. The double deck pre-screen (7’x3’) (2.200mm x 1.000mm) ensures perfect screening and the material can be stockpiled by the side conveyors, or can go via the crusher bypass. The impact crusher with an inlet opening of 31”x41” (800mm x 1.050mm) (HxW) is driven by a 200kW electric motor and drives the rotor, with a width of 39” (1.000mm) and a diameter of 50” (1.260mm), with an extremely high mass moment of inertia, which gives high productivity and stability. The 2-deck precision screen, 15’7″ x 5’ (4.760mm x 1.500mm) can be placed in closed circuit. The middle and fine fraction can be stockpiled as an additional option. The swivelling oversize conveyor can easily be changed to a stockpile conveyor if wanted.

The R5e shown at Conexpo has a drop off engine/gen set of 5sT (4,5t) which can be placed either on the chassis of the machine or it can be placed besides the machine, connected with a power cable. Being placed in a less dusty and vibrant environment it functions as a backup when there is no connectivity to the grid available. Maintenance is also safer and easier when the engine is placed at ground level. When connecting several machines to a single drop-off engine /gen set, it results in huge savings as there is only one engine/gen set to run and to maintain.

The R5e uses on average 173 kW when powered full electric or around 10 gal/hour (40l/h) when driven via the drop off diesel engine/gen set.

Looking forward to a succesful show and I hope we can meet you agin in person on our booth C-31386 Central Hall.
