It\'s also the first time to design and study the structure of new typed fluidized bed jet mill. Adding fresh air to the top and the bottom in the fluidized bed jet mill to increase the speed of upward currents, the way is leading fluidized particles to be boiling and reduce the eddy strength. The aim is to reduce the opportunity of regrinding. It is valuable to produce the particles which are rough, high density and high product rate requirement. At present, the technology has been prevailed, which produced lots of benefits for society and economy.
