Shanbao has introduced a new mobile jaw crusher it will sell in both China and emergent markets. This track-mounted machine has been designed and developed in the firm’s factory close to Shanghai. Olivia Weng, international sales director explained that the crusher can be used in an array of applications in the cement, quarrying and asphalt sectors. She said, “We developed a mobile machine as it’s more versatile than a fixed plant.”
At Savage Stone’s 161.9ha quarry in Jessup, Maryland, gabbro is extracted from five 13.1m-tall benches, with chemical rock hardness increasing with each lower level.
The shot rock (similar to granite and good for coarse road base) used to be loaded into Volvo 31tonne and 36tonne capacity articulated haulers and 90tonne capacity Euclid rigid haulers and transported 800m uphill to the primary crusher, a Lippmann 5062 jaw crusher. The jaw crusher processes rock to 127-178mm, which is then stockpiled on the s
Advances in asphalt plant technology were in major evidence at the bauma 2016 exhibition in Munich - Mike Woof writes
One of the most apparent developments at bauma 2016 was the strong focus on asphalt plant technology. The massive physical presence of the asphalt plants could be seen from a distance, right across the showground, particularly the 50m-high machine Benninghoven had opted to exhibit. However, other plant systems from rival firms Ammann, Lintec and Marini, as well as Turkish company E-MAK, c
Sunward has focussed particularly on building small-medium sized machines, said Li Lihong of the firm. An innovative development from Sunward is its new hybrid excavator design. This 22.6tonne machine has been developed with a view to offering lower fuel consumption than conventional excavators in its size class. As fuel prices are high in China, a hybrid machine offers incentives to the customer base and is said to be most effective in operations requiring slewing, such as for production truck loading. Pow
