Flip-Flop Screen
The flip-flop screen uses the principle of sub-resonance of two-mass body: the fixed screen frame of linear vibration and the excited floating screen frame form a resonance system, and the two produce relative motion. During this process, the elastic polyurethane screen surface continuously expands and contracts at a frequency of 800 times per minute, so as to obtain a high acceleration (50g), which effectively prevents the screen hole from clogging.
1. Since the screen surface can transmit the acceleration of 50G to the material by the relaxation movement, it can screen the difficult-to-screen materials, and the screen holes are not easy to be blocked.
2. The respective advantages of banana sieve and relaxation sieve are organically integrated. At the feeding end, the material speed is fast, the material layer is thin, a large amount of material is screened through, and the processing capacity is high. The inclination angle of the screen surface at the discharge end is low, and the material speed is slow, which can thoroughly screen the remaining under the screen and achieve a very high screening efficiency.
3. The box-type vibration exciter with linear motion has high reliability and simple maintenance.
4. The polyurethane sieve plate of the relaxation screen is specially designed by Tongtai Machinery Company to withstand the vibration intensity of 50g and 800 times of varicose per minute. The sieve plate has a long service life and the sieve machine is located on a hollow rubber spring. Noise Small, and the rubber spring has a long life. The load on the screen and support structure is much smaller than that of a conventional slack screen (although the slack screen can generate a vibration intensity of 50g, which is much greater than the 5g of a traditional sieve).
5. The "U" shape of the side of the screening machine is designed to form a seal, the side plate is not worn, and it prevents the upper screen from entering the screen, and the screen plate is fixed with a wedge-shaped rubber strip without any bolts. The extension has few rotating parts, high operational reliability, less daily maintenance workload, high utilization rate, and adjustable amplitude of the floating screen frame.
