Description of rectangular gyratory sifter Rectangular Gyratory Sifter Machine is also called reciprocating screen / square tumbler screen, if see from the motion trail of screen box. The vibratory force produced by its driving device is the inertial force twining along the dead axle, the direction of which is change according to a certain regular. The essence of square swinging screen is the reciprocating inertial force formed by the rotation of eccentric wheel winding the dead axle. According to the structure characteristics and working principle of swinging screen, the screen surface is arranged with level or incline (angle of inclination is 0-5 degree). After turn on the swinging screen, the screen box take reciprocating movement under the inertial force, screen box drives screen surface to make periodic shaking, which makes the materials on the screen surface to make directional jumping movement with the screen box. During the period, the material less than the screen aperture falls to under layer, the material bigger than the screen aperture make jumping movement, discharged from the coarse outlet. This equipment is a super-square tumbler screen (SYT-FYBS) model developed and produced by our company with a hanging structure. It has applied for a number of national protection patents and is leading the industry. The screen mesh frame and the screen mesh installation method adopt a unique and innovative design, and the installation is very convenient. Usually 9-layer design, can be divided into 10 grades at one time, or 4 layers + 4 layers equivalent to 2 sets sieve machine, or 2 layers + 2 layers + 2 layers equivalent to 3 sets sieve machine Or designed as 1 layer +1 layer +1 layer +1 layer +1 layer is equivalent to 5�  sets sieve machines. Applicable industry of square tumbler screen: Abrasive material and ceramic industry:� building sand, mica, alumina, abrasive, refractory material, slurry, etc. Chemical industry:� resin pigment, medicine, grease, paint, palette, etc. Food industry:� sugar, salt, alkali, gourmet powder, starch, milk powder, yeast powder, pollen, food additive, etc. Metallurgy and mining industry:� quartz sand, ore, meteorite,garnet, etc. Mechanical industry:� casting sand, powder metallurgy, electromagnetic material andmetal powder, etc. Technical parameters Model Screen size Screening area�  Screen inclination Layers Power Number of turns Case travel FYBS1535 1.5*3.5m 4.5-9 m2 5-8 1-9 5.5 kw 180-260 25-60 mm
