Plant Description
This plant, which has been erected inRotterdam’s port area, can handle concrete (with or without rebars), building rubble and broken asphalt paving at a rate of up to 1,000 tons per hour. From a feed material of up to 1.5 metres edge length, a product of 80 % minus 45 mm is generated in a single pass.
This performance is achieved by the world’s largest impact crusher, the AP-PH 2530 with a GSK-type rotor 2.5 metres in diameter and 3 metres in width and driven by an 800 kW slip ring motor. Material feed is effected by two apron conveyors, the first of which extracts the raw material from the storage hopper with the second – faster-running – conveyor opening up the material flow to provide for the smooth and uniform feeding of an eccentric screen which separates the fines fraction
from the material flow prior to its entry into the impactor. The crushed material is conveyed from the impactor by two vibro chutes installed in line. At this point in the operation is a magnet separator for the removal of ferrous metal inclusions. The plant was delivered complete with steel structures and electrical switchgear.
Thanks to the size and rugged construction of the impactor, extremely low wear rate figures are anticipated, so that maintenance intervals and downtime for wear parts replacement are kept to a minimum. Moreover, a number of maintenance aids are provided to minimise the time and effort expended for such operations.
