Selling points of the flip flow screen.(1) High acceleration allows the material to be fully dispersed, more material reaches the screen holes in a given time and the trampoline effect reduces the total amount of adhering particles, resulting in a higher production capacity; (2) The flexible flip flow screen plate is continuously bent, which prevents the material from sticking to the screen plate; (3) The stretching of the screen plate leads to a slight enlargement of the screen holes in the tension direction, which effectively prevents the screen holes from being blocked by particles close to the screen hole size. (4) The polyurethane screen plate has good abrasion resistance, good elasticity, high elongation at break and resistance to bending and winding, which makes it ideal for screening of wet materials.
The difference between the flip flow screen and the common vibrating screen.(1) The vibration principle is different: the vibration of the flip flow screen consists of two parts: circular or linear vibration produced by the exciter and flaccid vibration of the screen surface produced by the floating screen frame. Ordinary vibrating screen is only by the exciter to produce circular vibration or linear vibration, screen surface and vibrating screen is one vibration. (2) Different vibration strength: due to the double vibration principle, the vibration strength of the flip flow screen is higher than that of the ordinary vibrating screen, resulting in higher screening efficiency; (3) The flip flow screen is highly adaptable to the screening material, and can handle wet and sticky difficult to screen materials, and is not easy to block the screen hole.
Commissioning of the flip flow screen.The test run of the machine should last at least 4 hours, during which it is checked by hearing, sight and touch. This machine should start smoothly, without special noise and operate reliably. All parts of this machine should reach a predetermined stroke and must make a reciprocating linear movement in the direction of the excitation force. The cross-swing of the screen box of it shall not be too large during operation. Shaker bearing temperature gradually rise, 3 hours after the bearing temperature shall not exceed 85 ℃, the temperature rise shall not exceed 45 ℃, that is, the temperature remains basically constant. After 4 hours of empty operation, check whether the its bolts are loose, if loose should be tightened in time.
