Today, The status of China is stronger and stronger, and China is having a renaissance, China and dream is realizing. In 2011, China became the worlds second largest economy by 5.4742 trillion US dollars, and Chinais also transforming from made in China to created in China. With the new pace of urbanization, urban scale of Chinamajor cities is expanding rapidly, so investment in the subway also became an ideal choice of many cities. The sand making machine and mobile crushing plant or mobile crusher with advanced technology and excellent quality will play a huge role in the subway construction.

According to media reports, in the next three years, mass mileage of urban railway will add 1000 km, so for the next three years, nine cities will bid farewell to the history of non-Metro. The nine cities are: Qingdao, Wuxi, Changzhou, Fuzhou, Dongguan, Nanchang, Zhengzhou, Changsha and Harbin.

Subway construction requires a lot of sand and aggregate, and because of the lack of natural stone, artificial stone has become the preferred. The gravel aggregate production line produced by zenith includes vibration feeders, jaw crusher, vertical shaft impact crusher (sand making machine), vibrating screen, sand washing machine, belt conveyor, centralized electric control and other equipment, with mature technology, and zenith can research and produce all equipment needed in the stone production line. The full range of design and production makes the best coordination between equipment and motor. zenith can also produce various mobile crushing plants, through mobile crusher, construction site waste can be broken and migrated quickly and easily, sand making directly next to the site is also OK, saving transport costs.

Ore processing is high-energy, high-polluting, and also needs high costs. Jaw crusher is expert in green ore processing field, better for the ecological environment as technology of crushing process improved. The working principle improvement of jaw crusher shows that: High crushing strength, low loss, less dust and particle size reduction is one of the most important ways to improve the coal mining equipment efficiency and reduce costs.When the movable jaw come to fixed jaw, the material is crushed by the impact and compression. While the movable jaw leaves the fixed jaw, the finished product discharged from the discharge port by its own gravity. No rigid connection between the movable jaw and the transmission part. About 12% of the electricity consumption for jaw crusher can be used for crushing material, and more than 80 percent of which is used for ore grinding .Mechanical and electrical consumption of jaw crusher is small, easy maintenance, low operating costs.

Our jaw broken machine manufacturers after decades of practice and concluded, in broken field strongly advocated more crushing and less grinding process, namely to reduce the final size of the crushed product. Jaw crusher is green mineral processing equipment industry experts, increasing the content of fine particles in the crushing products, thereby increasing the processing capacity of the mill, to reduce power consumption and mechanical consumption, reduce costs and increase economic efficiency.Jaw crusher has a very broad application in mining, metallurgy, construction, cement, building materials in the field of material crushing process; when put into use, the technical upgrading, overall strength will be enhanced. We can narrow the gap and improve the international competitiveness. It is really of practical significance and we can have an enormous social and economic benefits.

Whether people, vehicles and goods usually have regular maintenance, otherwise there will be "slight illness", and crusher equipment is also included. When used crusher equipment, maintenance work can not be ignored. Routine maintenance of quarry crusher is the best way to extend the life of the machine.Crusher equipment, under normal operating conditions, must be regular maintenance. Maintenance is important way to prevent and delay parts wear and other forms of failure.

Adhering to lubricate all the parts and maintain equipment for normal production every day, and extended equipment life. We should not only pay attention to making lubrication, but also tightness inspection of each screw, such as backing blade etc.. Vibrations occur will cause screw loose, so a timely routine maintenance and check can ensure equipment in availability. The crusher can keep in high performance, reducing equipment accidents,which improves economic efficiency.As the pioneer of crusher industry, SBM Machinery Co.,Ltd. field has been in the forefront of science and technology industry in crusher technology. Since its inception, SBM has been committed to the crusher technology research, which promotes the development of the industry. SBM developed and manufactured a variety of crushers and has maintained a reputation for excellence, the "SBM is increasingly competitive and well developed. SBM remind you that pay attention to regular maintenance of the crusher.
