When the impeller rotates a large amount of air can be sucked along the vertical pipe Below the cover is fixed protective disk The gap between the safety disk and the impeller depends on the amount of sucked air It can not be larger than 3mm at most When the gap is too large replace the abraded protective disc and make appropriate adjustment

Shandong Xuridong Machinery Co Ltd is a hightech enterprise integrating scientific research and development manufacturing and technical services The company has more than ten years of experience in the production of paper pulping equipment and environmental protection equipment and has a complete and scientific quality management system

Oct 01 2016 The rotorstator mechanism that drives a flash flotation cell is usually the same as one that would be used in a conventional tank cell of the same manufacture Although the mechanism is the same there are several significant differences between this type of flotation machine and a conventional flotation machine most notably

Jun 22 2015 An important requirement of any flotation machine is the ability to provide uniform aeration throughout as large a volume of the machine as is possible In addition the size distribution of the gas bubbles generated by the machine is also important but experience has shown that the proper choice of frother type and dosage generally dominates the bubble size distributions being produced

the boom against wind and wave action may also serve as a weight or ballast to add stability and help keep the boom upright Booms can be divided into several basic types Fence booms have a high freeboard and a flat flotation device making them least effective in rough water where wave and wind action can cause the boom to twist Round or
