Development of griddle should take the road of independent innovation

When a customer griddle pleading quality and performance increasing , while the current griddle existing technologies have not meet the needs of customers . From time to time so just griddle innovation , competence in the Chinese market stand foot footing . Also a large griddle industry is currently the only one way out !
According to statistical data coal vibrating screen analysis of the current large griddle consumer and small business have more than a thousand . When the griddle market once again usher in a new period of expansion after midnight, our griddle consumer 's way where is it ?
Although our griddle consumer business a lot, but less common are some of the range of small businesses. These technology companies are bringing technology from abroad , but these technologies in foreign countries who are some of the techniques to Mining vibrating screen be eliminated , assuming that these are the use of obsolete technology in China

That does not have the competitive edge.
Large griddle industry expanded in the coming years a trend has been reported in the major news online too . Therefore, screening equipment, mining expansion in the coming years is indisputable , the state and a lot of businesses are optimistic about the market . Although griddle had read in our country has experienced decades of

Expand the current range is huge. Once griddle has faced the frozen period, and as usual, real estate and infrastructure in recent years to establish a prosperous once again visibly large griddle industry , ushered in a new development period .
In addition , the current large griddle again commenced on behalf of the technically will have a higher level of increase, assuming still stay in place , not innovation , it can be said that the road ahead will be a dead end .

Gridiron works

     Line screen work, two synchronized reverse rotation of the motor exciter excitation force generated reverse , forcing the linear sieve sieve sieve driven longitudinal

movement to do so by the Screen machine exciting force on the material is periodically thrown forward a range, thus completing the material screening operations . Linear vibrating screen is a

dual vibration motors. plate feeder When two linear vibration motor sieve to synchronize and rotating anti- Fou , the eccentric block of the excitation force generated by the motor axis

parallel to the direction of offset in the vertical direction of the motor shaft is a stacked together , so screening machine the trajectory is a straight line . Two motor shaft
