greenhouse gases and help developing countries.
China is now the leading
producer of greenhouse gases. But the United States and other industrialized

will be able to achieve the goal of low carbon environmental protection, which
will not only save energy, save materials, environmental friendly, but also
reuse mining waste machinery products will get improved and make breakthrough.
But developing countries are also being urged to do more. And they, in turn,
want help. They criticized a proposal for industrialized nations to pay

was the warmest decade on record. And it said this week that final results will
likely show two thousand nine was the fifth-warmest year on record.
When a
higher requirement to crushing degree, crushing operations of cone crusher are
often composed of several crushers to complete the mechanical crushing system.
In the system, materials should get through all crushers, and its particle size
is gradually reduced, and finally reach the required particle size. In this
crushing system, each stage should selecte appropriate milling machinery and
crushing size, so as to maintain the production capacity coordinated between the
various stages.
In New York, the United Nations secretary-general reacted to
