Process for crushing auxiliary raw materials in desulfurization and denitration

2020-03-19View Original

Thread Content

The material is conveyed from the feeding device to the crushing chamber of the main unit, where it is crushed through mutual impact, collision, friction, shearing, and compression with high-speed rotating components and particles. The crushed material is separated into coarse and fine particles using a classification wheel; the coarse particles flow back into the crushing chamber for further grinding, while the purified gas is discharged by an exhaust fan. Equipment features: 1. Low energy consumption: It combines centrifugal crushing, impact crushing, and extrusion crushing, saving 40–50% more energy compared to other types of mechanical crushers. 2. High fineness: Equipped with a self-flow classification system, the product fineness is ≥2500 mesh. 3. Wide feeding range: The particle size of the feed can be up to ≤50mm, and the material only requires primary crushing equipment. 4. Low wear: The vulnerable components in the crushing section are made of new composite wear-resistant materials, ensuring a long service life; there is no pollution when processing materials with a Mohs hardness of ≤5. 5. High mechanical stability: It can operate continuously for 24 hours a day without interruption. 6. Comprehensive functionality: It can crush needle-shaped materials, achieving a length-to-diameter ratio of 15:1 for the finished products ;    There is no temperature rise during the crushing process, making it suitable for crushing heat-sensitive materials ;    It can disperse sintered and agglomerated ultra-fine materials, achieving a particle size recovery rate of 100% ;    It has a particle shaping function that effectively improves the bulk density.    Materials that can crush fibrous tissue ;    It can crush materials with a high moisture content and has a drying function ;    It can crush materials with high viscosity. 7. Negative-pressure production eliminates dust pollution, resulting in an excellent environment. 8. High degree of automation, strong stability, and easy operation. 9. The entire system is equipped with automated control, allowing for one-button start/stop; it is simple to operate, and can be connected to a central control system for remote control.
