high-speed dispersion machinesuitable for dyestuff, pigment, paint, ink, adhesives to stir, dissolve and disperse liquid ,liquid-solid material. Features: Air drum save minimum when stirring and dispersing. Good mixing and stirring effect, middle or high speed stirring and dispersion make the material dissolve quickly and particles small. Recommending the essential factors on the selection of the model of the F series dispersion machines Models and adapted powers of frames: 1. Adapted power of FG200 frame:1.5KW;2.2KW;4KW 2. Adapted power of FG250 frame:5.5KW;7.5KW,9/11KW;11KW 3. Adapted power of FG350 frame:11KW;15KW;18.5KW;18.5/22KW;22KW;30KW 4. Adapted power of other frames;1.5KW,2.2KW,4KW,30KW,37KW,30/42KW,45KW,55KW,75KW,90KW Requirements of speed: 1. kinds of speed : single speed, 2-speed, step-less speed change, stepwise speed change(multiple speed). 2. ways of speed change: electromagnetic speed change, frequency-conversion speed change, decelerator speed change, governing belt speed change. 3. ranges of speed: low speed(below 400 r/min), high speed (400-1200 r/min), very high speed(over1200 r/min). Types of dispersing discs: flat disc with saw-teeth, trifurcate oars, dish, other types. Types of installation: floor type, platform(platform frame)type Ratio of the diameter of the materials drum and the diameter of the dispersing disc:3-4:1 Motors and electrical equipments: anti-explosion type, non-explosion-proof type(ordinary type),special requirements type. Forms of installing the motors: upward installation of the motor output axis end, downward installation of the motor output axis end(generally, big power motors of the frame type machines such as model f22 and above are suggested to use this form).
