Oval sieve economy haixing mechanical shaker oval when dealing with highly viscous fluids obvious advantages, such a condition, by optimizing the balanced elliptical motion trajectory and efficient removal of viscous solid phase, so drilling the larger particles is effectively cleared, while the vibration intensity relative ease of screening can effectively reduce consumption. Features and Benefits: balanced elliptical trajectory can effectively reduce obstruction sieve, sieve through rate guarantee will help improve the viscous fluids in cuttings transport speed, to prevent the paste screen can handle large proportion of highly viscous fluids even more dry cuttings Zhang long screen life fast tension system for easy replacement screen -1 ° ~ + 5 ° angle adjustment device screen frame has a weir feed box and the box there are two kinds of crochet mesh sieve and plane wave Screen details reference http://www.chinahaisun.com/Product/gksb/150.html
