The Middle East`s first Atlas Copco HB 10000 hydraulic breaker has recently been commissioned in Saudi Arabia. Eastern Province Cement Company (EPCC) in Dammam, Saudi Arabia are the first to benefit from the world’s largest commercially available hydraulic breaker, Atlas Copco’s HB 10000.
Weighing an impressive 10 tones and with a single impact blow energy of 16,000 Joules, which can be released at a rate of up to 380 blows a minute, the HB 10000, mounted on a Komatsu PC 1250 excavator, packs a substantial punch. To put that in perspective, 16,000 Joules equals a weight force of 760 metric tons, more than the landing pressure of an Airbus A380 airplane, repeated 380 times a minute.
The HB 10000 breaker will be used for primary breaking applications in the hard limestone deposits which are arranged in a dam formation in the quarry. The site not only presents harsh conditions but extreme temperatures too, with ambient temperatures reaching up to 51°C.
“The HB 10000 provides an ideal solution for EPCC’s primary quarrying application. The combination of extreme power and efficiency provided by the breaker gives real operational savings, making it an unrivalled cost-effective production machine for primary rock breaking,” said Fiaz Ghani, Regional Business Line Manger – Atlas Copco Construction Tools.
Established in 1982, EPCC is now one of the leading cement companies in Saudi Arabia producing clinker and cement for both local and global markets.
“We are facing very hard rock, which lowers traditional dozer productivity, compared with a hydraulic breaker, in this type of deposit and achieved a lower cost per ton”
The high power-to-weight ratio and the in-built EnergyRecovery feature provided by the HB 10000 makes it an excellent cost-effective option. Its lower weight and higher efficiency means less hydraulic input power is required from the carrier, while maintaining maximum impact performance. This allows smaller carriers to be used resulting in significant savings in investment costs. In fact, the HB10000 can run on carriers between 85 to 140 metric ton weight classes. With less input demanded from the hydraulic system, less fuel is needed by the carrier, which results in further lowering operating costs.
Powered by a combination of oil and gas, the HB 10000 becomes less dependent from the carriers hydraulic oil supply. This results in 70% of the impact energy being regenerated by the gas in the piston accumulator and only 30% by the hydraulic oil supply of the carrier. In effect the internal control valve is able to convert the hydraulic input into a greater hydraulic output.
