With the development of slag pressure ball machine technology advances, now in many areas around the world slag pressure ball machine have been widely used, many overseas countries have already provided slag pressure ball machine manufacturers and research institutions, and technical level of development is far more than China, all types of pressure ball machine so that the industry has come out with a more open development. Development slag pressure ball machine not only various ore raw energy saving easy to transport, but also improve the utilization of waste, especially in developed countries, high quality requirements on the environment, the emergence of pressure the ball technology can greatly ease the type coal production and other industries to pollute the environment, but also create new economic benefits. It is also accompanied by a wide range of applications of coal on the environment and the people have become increasingly demanding, slag pressure ball machine briquette together has been accompanied by widespread development.
