Henan Yuhui  mining equipment Co., LTD, prepare production line of the vibration sieve double motor drive, when two sets of vibration motor do synchronization, the Fou rotates, produced by the eccentric block vibration force in the direction of the axis parallel to the motor offset each other, in the direction of the axis perpendicular to the motor of for a resultant force, so sieve machine movement track for a straight line. The two motor shaft relative sieving a dip Angle, in the exciting force and materials of the gravity force function, materials in a sieve surface being thrown around the forward by leaps and bounds for linear motion, so as to achieve the screening of material and classification of the goal. Can be used to realize automation line homework. With low energy consumption and high efficiency, simple structure, easy maintenance, fully closed structure no dust overflowing scattered characteristics. The highest screening mesh 400 mesh, can screen gives 7 different granularity material
