1.The series of stirrers are used SB90-278、SB90-279 standard equivalently，used to mill no even system liquid whose viscosity is 15000 centipoises,and density is 2000kg/m3 to solve fiber matter of crystal or no crystal and keep solid granule be equal floating state.

2.Rot content of stirrer:carbon steel is2mm and stainless steel is 0.

At low velocity,it is horizontal circumferential flow and axial flow.And at high velocity,it is radial flow and axial flow.There is a strong eddy current at the front end of the blade.It can be operated in laminar and turbulent zone.
