Fully mobile crushing in China

Last month, Baiyinhua Coal Corp. held the official ceremony celebrating the first operation the first of four fully mobile crushing systems at Baiyinhua coalfield. This first system will be used to remove overburden with a nominal capacity of 6000 tph. It comprises a crawler-mounted crusher MC 6000, a mobile conveyor bridge and a hopper car with cable reel car. The equipment is designed to operate under extreme climatic conditions as temperatures fall to 40°C below in winter.

Promoting the development of coal production
A large 50 m³ capacity shovel feeds the hopper of the crushing plant, which is equipped with a double-roll crusher. After crushing, the material is continuously transported with belt conveyors, eliminating the need for conventional truck transport. “The application of this advanced mining equipment shall generate Baiyinhua Coal Corp. a long-term economic benefit, promoting the development of coal production”, Mr Liu Yi, deputy general manager of Mengdong Energy, pointed out in his speech at the ceremony.

It is planned that the other three crushing systems will be put into operation before 2015. Two of them will also be used to remove overburden with a capacity of 6000 tph, each; the other will be used for coal mining with a capacity of 3000 tph. ThyssenKrupp is responsible for the design, engineering and construction of all four crushing systems.

Cutting carbon in the coal mining process
Demand for fully mobile in-pit crushing systems is growing in large opencast mining operations around the world. The ThyssenKrupp Resource Technologies’ Mining Business developed these plants for combined use with power shovels. Fully mobile crushers are powered exclusively by electricity, cutting carbon dioxide emissions cut by up to 100,000 tpa.
