Powerscreen sell first dual-powered screen in Oman

Road contractor takes delivery of dual-powered Warrior 1800 screens for aggregate production

POWERSCREEN have recently sold their first dual-powered screening machine into Oman.

Alisco Strong Plant, one of the leading road contractors in the country, operate a crushing and screening facility in Barka that uses readily available river bed gravel to produce aggregates for asphalt, granular sub-base and basecourse.

However, the Barka deposits produce a sand that is prone to rejection due to inherent impurities in the feed material, which ranges from 0–300mm in size with more than 50% of the material at –65mm.

Due to scarcity of water in Oman, a washing plant was considered to be the option of last resort, so Alisco Strong Plant – an established customer of Powerscreen’s local distributor Genserv – consulted the Genserv sales team and invited them to come up with a solution.

Alisco were already using a Powerscreen 1412 Trackpactor crusher and a Powerscreen Chieftain 2100X screen, and Genserv’s simple solution involved the addition of a Warrior 1800 scalping screen to screen the deposit into 0–50mm, 50–150mm and +150mm.

To address Alisco’s desire to use electricity as a power source, the Genserv team further proposed the Warrior 1800 with dual-power option.

Convinced by Genserv’s recommendations, Alisco placed an order for two Warrior 1800 units with the dual-power option. Both machines were commissioned at the Barka site are now comfortably producing 400 tonnes/h of different sized materials.

According to Powerscreen, the dual-power system provides flexibility to address a number of challenges and opportunities, particularly where electricity is cheaper than diesel fuel or where only electricity is permitted on site.

Once connected to an external electricity source, the unit retains all the benefits of a mobile machine but operates with zero emissions.

Moreover, with the option to operate on diesel fuel oil or electricity, the dual-power mobile screens can reduce fuel oil consumption, operating costs and, depending on set-up, machine downtime, thanks to fewer refuelling and engine servicing requirements.
