Works to make the screen surface material at a constant speed toward the discharge end of the move, the material also be screening. Shaking screen compared with the several screens, its relatively high productivity and screening efficiency. The disadvantage is that the power balance is poor. General Concentrator rarely use it, and be replaced by more structured shaker. Work characteristics ①, using block eccentric as the exciting force, large circular vibrating screen, vibrating strong. ②, sieve and screen box beams using high strength bolts, simple structure, convenient maintenance; ③ using tire couplings, flexible connection, smooth operation; ④, the use of small amplitude, high frequency, high angle structure of the screening machine high efficiency, handling the largest, long life, low power consumption, small noise. According to the structure and working principle screening machine generally have the following categories: 1. Face roller screen is horizontally arranged a root roll axis configuration. 2. Roller Screen Face is horizontally arranged a root roll axis configuration. Grate working part fixed and circular vibrating screen classification, by sliding along the working surface material leaving the material to get screening. Fixed grid screen is more of a concentrator application, generally used for pre-screening coarse crushed or broken before. It is simple, easy to manufacture. Do not consume power, you can directly unload the ore to the screen surface. The main disadvantage is the low productivity, low screening efficiency, generally only 50-60%. 3, the plane motion sieve body is a plane swing or vibration. Its flat trajectory is divided into linear motion, circular motion, elliptical motion and complex motion. Shaking screens and shaker in this category. Vibration sieve is a high precision powder screening machine, its low noise, high efficiency, rapid changer takes 3-5 minutes, Henan circular vibrating screen, fully enclosed structure, suitable for grain, flour, mucus and other materials screening min filtration. Vibration sieve is upright motor as vibration source, the motor and lower ends are mounted eccentric weight, the rotary motion of the motor into a horizontal, vertical, inclined three yuan movement, then the movement is transmitted to the screen surface . The regulator, the phase angle at both ends, can change the trajectory of the screen surface material in. Isolation means (a plurality of support springs), the base of several components, wherein the screen cover and screen frame vibration part, the rest of the non-vibrating part, in addition, the double circular vibrating screen, both the base support functions. Vibration sieve screen frame is a major part of the vibration part. The screen frame is usually welded from sheet roll, its upper and lower ends have a receiving coil, at an internal ring is provided with a flange for fixing the screen assembly and other structures.
