Product overview
Coal-fired power plants burning coal is mostly without screening of raw coal, its size is uneven, before entering the boiler should be screening crushing processing, design and manufacture of suitable for different types and screening equipment,after years of painstaking researchmy company practice exploration, and sums up the experience in many ways, eclecticism, developed to produce a GS type banana type roller screen, the machine has a large capacity, high efficiency, compact structure, can adapt to the characteristics of high moisture lignite, since put on the market, has been praised by the medium and large power plant.









1. The accessories is unified, replacement and maintenance.
2. To add bypass in that small particles can directly enter the system.
3. The screen surface adopt wear-resisting material, durable, and replacement and maintenance are very convenient.
4. Strong adaptability of coal, is not easy to block coal, especially for high moisture lignite is more outstanding.
5. Adding coal wall signals, and adding the wear plate and rubber type cleaning structure, safety protection and prevent effect.
6. As a result of single machine single shaft rotation, and uses the roller motor, big start torque, the entire screen surface is stable, reliable and has little noise.
7. Because the screen shaft is at thirty percent structure 5 ° to 10 °, 15 ° to decorate.Shape like a banana, and beautiful appearance, advanced structure, therefore calls "banana" type roller screen.



Working principles

GS type banana type roller screen is a kind of using multiple spindle rotation, push forward material, and at the same time for screening equipment, its working mechanism is rows of sieve shaft, each screen shaft driven by a roller motor respectively, and in the same direction, make the material move down the forward, stir up the material at the same time, less than the screen hole size and particle, the gravity and screen the effect of axial spinning force along the mesh, is greater than the screen hole size of particles on the sieve surface to continue moving forward, and falling into coal crusher.
