Impact crusher applies to produce green concrete
Apr, 19 2012
(China) -- In recent years, China has carried out the rectification work of the green concrete equipment in the capital Beijing, the first round of implementation, its effectiveness significantly, Beijing initiatives and vigorously promote the ready-mix concrete mixing station control integration, the level of environmental protection of the city's mixing station domestic leading, mixing station beginning to achieve governance effectiveness.
July 8, the Beijing Municipal Housing and Urban-Rural Construction Committee announced the first 22 green production standards, concrete mixing station.
This initiative will gradually push the major concrete equipment market, concrete processing is the next big effort, especially since issued the "12th Five-Year Plan, the infrastructure around the building and road and bridge construction are gradually open increasing demand for concrete, but also to ensure that the environmental performance of concrete equipment, and to avoid recidivism in the past "pollution first and treatment later" error. The most important concrete aggregate processing of course, cannot let go, according to the important position occupied by the crusher and sand making equipment in the stone production line, select aggregate crushing equipment to be careful.
Red Star machine production of the crusher is developed on the basis of the hammer crusher. The impact crusher is applied to industrial production in 1924. And hammer to break the impact kinetic energy to crush materials broken machinery, there are many similarities in the working principle and performance structure.
Red Star machine crusher hammer and the rotor is a rigid connection, Yang hit the broken hold angle fracture zone within the chassis. Chunk of material from the feed port feeding, first by high-speed rotation of the hammer is broken by the impact of the bottom, and was quickly thrown to the back plate hammer broken, or a rebound to return the broken area, once again hammer impact, continue to repeat the process.
Between commuting, the material will collide with each other, resulting in self-hit smash. After several times, multi-role composite crushed, if the particle size is less than the gap between the back plate and nutation, from the chassis lower part of the discharge port; if greater than the gap will be rigid hammer milling and grinding broken, until discharged. Thus, the crusher crushing effect of the following three aspects: free broken rebound crushing, milling broken. Red Star machine impact crusher fundamentally different construction materials required for a variety of solid materials crushed requirements.
