Product relaunch

 

"Dosco Overseas Engineering are to relaunch their range of crushers for both the home and overseas markets. The company’s crusher range is based on the three main principles of breaking minerals — impact, compression and shear."

"The DFB 12-12 feeder breaker is a free-standing machine complete with its own chain scraper conveyor which pulls material under a single rotor that turns at high speed to break the material by impact. Product size is dictated by the distance between the conveyor and the underside of the rotor. Throughputs of 1,000 tonnes/h of medium-to-hard stone can be achieved with in-feed sizes of 1.2m3 being processed to a product size of 200mm in one pass."

 

"The DFS crusher is a free-standing unit with an integral feeder pulling material under a rotating drum. The rotor rotates at a slow speed and, being fitted with mining-type picks, breaks the infeed material by compression. The DFS is suitable as a portable unit for processing soft-to-medium-hard material with a breaking ratio of 8:1 and with throughputs of up to 1,800 tonnes/h."

"Dosco also offer a range of twin-roll crushers. Two contra-rotating shafts are fitted with a configuration of cutting elements that initially shear the processed material and then crush it by compression between two rolls. Size for size, the twin-roll machines can attain throughputs greater than machines working by other principles as the cutting elements only work on the oversize material, with the undersize being rotated straight through the machine."
