Stevin Rock UAE with Terex Pegson & Powerscreen International
Tuesday, October 2nd, 2007
Stevin Rock is the leading aggregate company in the Gulf region producing in excess of 30million tonne per annum, with the majority the major building project in the region being supplied. These projects range from the innovative luxury islands off Dubai – Palm Jumeirah and the World Island to the futuristic international airport at Doha, Qatar.
The booming economy in the region has resulted in an increased demand for aggregates meeting the exacting quality standards. To meet this increased demand with the lease amount of lead time, the solution was to commission a new mobile crushing train utilising Terex Pegson & Powerscreen expertise. For this Stevin Rock turned to Genavco, the Terex Pegson and Powerscreen Dealer for the UAE area. Within one month the equipment was supplied, commissioned and producing saleable material. The crushing and screening chain includes a Terex Pegson 1100×800 Premiertrak jaw crusher, a Terex Pegson 1300 Maxtrak cone crusher and a Powerscreen Chieftain 2400.
Doug Ross, Operations Manager at Stevin Rock said, â€œThe increase in production has resulted in improved supply to our important clients and the financial benifits of long term contracts due to the consistant ability of Stevin Rock to meet the customers quality requirements and delievery schedules.â€
The drawing shows the layout of this crushing and screening chain. The gabro stone is first fed to the Terex Pegson 1100×800 Premiertrak. This primary jaw crusher feeds the Terex Pegson 1300 Maxtrak which feeds the triple deck loading screen. This re-circulates the oversize (32mm+) back to the Terex Pegson 1300 Maxtrak and removes the fines of 0-3mm. The 3-32mm aggregate is then fed to the vertical shaft impactor which shapes the stone before screening it in the Powerscreen Chieftain 2400. This mobile screen has 3 decks with 20mm, 10mm and 5mm screen media. The oversize is re-circulated back to the VSI. This produces 3 end products: 0-5mm dry sand, 5-10mm for asphalt/ concrete production and 10-20mm for asphalt/ concrete production.
TEREX Pegson pioneered the development of the 1180 Premiertrak to produce a high performance large capacity tracked mounted jaw crusher that is suitable for a variety of quarrying and contract crushing applications.
Behind the success of the 1180 Premiertrak is the â€œMâ€ series S.H.D. single toggle jaw crusher which has been designed to deliver unsurpassed output levels on the toughest of applications.
This versatile unit is suitable for primary operations and will achieve capacities over 450 tph depending on the size and type of material being processed.
The 1300 Maxtrak is TEREX Pegsonâ€™s largest tracked cone crusher and is suitable for secondary and tertiary applications up to 350 tph.
This plant â€œpunches way above its sizeâ€ and is ideal to follow very high capacity primary jaw crushers and produce quality sub base or aggregates.
Using the unbeatable 1300 Automax cone crusher, the 1300 Maxtrak features a system with a large feed hopper which is able to take an â€˜all-in feedâ€™ from the jaw crusher, thereby improving cubicity, throughput and reduction ratios and eliminating the need to for pre-screening on most applications.
Setting adjustment can be made â€˜on the runâ€™ using touch button control. Dust suppression sprays and metal detection are both included as standard. Without question, the 1300 Maxtrak is a big step ahead of the competition in its size, productivity and operating efficiency.
The Powerscreen Chieftain 2400 is the largest mobile screening product in the Powerscreen Chieftain range. With higher stockpile heights, larger screening areas and more user-friendly conveyor systems, the Chieftain 2400 offers the mining, quarrying and recycling industries a true giant in screening plants. The Chieftain 2400 can accept a material feed of up to 6* (150mm) *Depending on mesh sizes and material used.
With the satisfactory performance of the new crushing & screening train, Stevin Rock has purchased further equipment to increase the production capacity of the original equipment supplied.
