What are the structural principles of an inertial vibrating screen?
Two rolling bearing vibrator 5 is fixed on the screen box in the middle, with emphasis on the 4 ends of the vibrator shaft wheel 6, adjusting weight 7 in biased wheel in different positions, can get different inertia force, so as to adjust the amplitude of the sieve. The motor installed on the fixed base drives the main shaft by the triangle belt pulley 3, so that the sieve generates vibration. A central circular trajectory; because of the action of the spring lining is both ends of trajectory sieve is elliptical to oval track direction near the feed end in advance, which makes the material speed increase; according to the different requirements for the production and the operating efficiency of the screen, can be installed into different slopes (15 ~25 OC) in the elliptical orbit near the direction toward the discharge end, in order to make the material progress slowed, is conducive to improve screening efficiency.
Domestic inertial vibrating screen has single layer, double deck, seat type and hanging type. The utility model is composed of a sieve box, a vibrator, a plate spring, a combined driving motor, etc.. The screen box 2 is fixed on the sieve box, and the sieve box is arranged on the two elliptic plate spring group 8, and the base of the plate spring set is fixed on the base with a slope of 15 DEG C and ~25 DEG C. The screen box is vibrating by a single axle inertial vibrator (a pure vibrator) fixed in it.
SZ type inertial vibrating sieve can be used in ore dressing plant, coal preparation plant and coking plant to screen ore, coal and coke, and the maximum particle size of the material is 100mm.The main difference between SXG type inertial vibrating screen and SZ type inertial vibrating screen is that the screen box of the sieve is hoisted by a spring suspension device. The motor drives the main shaft of the vibrator through a triangle belt, and the circular motion of the sieve is caused by the centrifugal force produced by the unbalanced weight of the vibrator. The sieve is suitable for the sieving of ores and coals.
