In addition, the Commerce Department data shows that in the first half of this year, China has suffered surveys from 18 countries and regions which initiate at anti-dumping, anti-subsidy and special protection. It has increased by 38% compared to last year. The Mineral Impact Crusher Machine is mainly made up of rotor rack, impact rack, ratchet wheel open-cover device, rotating parts as well as other components. There are two parallel rotors in the Mobile Impact Crusher with some altitude differences. The position of the first rotor is relatively high, with an angle of 12°from the node of the first and the second rotor.
The mobile stone crushing plant features high flexibility, strong mobility and saving a lot of infrastructure and relocation costs. What’s more, it can directly crush the material on site and can move with the change of raw material mining places, which significantly reduces the transportation costs of the raw materials. According to news reports: “At present, there are 38 new projects and old lines reconstruction project in China’s railway construction plan in this year, with the amount of investment of 420 billion Yuan, accounting for 80% of the annual investment plan; while other projects also exist uncertainties.” From the current communications of several items of task, China’s railway infrastructure will continue to “warm” in 2013, and new projects are expected to exceed last year. The Teeth Roll Crusher is generally composed of case cover, box, crushing roller, drive mechanism, gap adjusting mechanism, spring pressure mechanism, chassis and other components. The double roll crusher uses high extrusion pressure produced by the relative rotation of two high-strength durable crushing rolls to crush the materials.
After the materials entering the gap between the two crushing rollers, they will suffer from the action of extrusion force and shearing force produced by the rollers. After crushing, shearing and grinding processes, the materials are crushed to the required particle size and then they are output by the conveying device. According to the plan, Shanghai Railway, Chengdu-Guiyang Railway (Leshan to Guiyang segment), Chengdu-Kunming Railway (Chengdu to E’mei segment), Chengdu-Kunming Railway, Chengdu-Guiyang (Yunnan paragraph) and other new projects will start in this year. The aggregate is the most basic materials for railway construction, the beginning of railway project construction is bound to lead to aggregate demand, so the prospects of gravel market remain favorable, which provides a huge development space for roll crusher, sand making machine and other equipment for aggregates and sand production line. Henan Hongxing Mining Machinery Co., Ltd. is a large-scale mining machinery and equipment manufacturer major in producing crusher, grinding machine and sand making machine.
