Stainless Steel Laser-drilled Screens for Continuous Centrifugals
نویسندگان
چکیده
Stainless steel laser-drilled screens (SSL screens) for continuous sugar centrifugals are compared with several types of chrome/nickel screens. Assessments are made of trials and routine operations at several factories around the world, and results of final molasses purity analyses, screen service life, and centrifugal capacities are examined. A semi-quantitative comparison is made between Australia and South Africa on the use of SSL screens and chrome/nickel screens in these two sugar producing regions, which share similarities. The comparison illustrates some of the cost benefits of SSL screens. SSL screens are shown to be a cost effective alternative to both the standard and modified versions of chrome/nickel screens, in high grade and low grade continuous centrifugals.

Comparison of Laser-Engraved Hole Properties between Cold-Rolled and Laser Additive Manufactured Stainless Steel Sheets
Laser drilling and laser engraving are common manufacturing processes that are found in many applications. With the continuous progress of additive manufacturing (3D printing), these processes can now be applied to the materials used in 3D printing. However, there is a lack of knowledge about how these new materials behave when processed or machined. In this study, sheets of 316L stainless stee...

Factors affecting the capacity of continuous centrifugals handling "C" massecuite are examined after the completion of several test runs on various machines at different factories. Feed pipe sizing, water addition and positioning, feed distribution, scaling of screens, etc., are discussed and recommendations made. Introduction For several years continuous centrifugals (typically BMA K850) opera...
متن کاملParallel laser micromachining based on diffractive optical elements with dispersion compensated femtosecond pulses.
We experimentally demonstrate multi-beam high spatial resolution laser micromachining with femtosecond pulses. The effects of chromatic aberrations as well as pulse stretching on the material processed due to diffraction were significantly mitigated by using a suited dispersion compensated module (DCM). This permits to increase the area of processing in a factor 3 in comparison with a conventio...
متن کاملQuality Assessment of the Filtering Screens Used in Sugar Processing Centrifugals
The condition of the filtering screens used for separating sugar crystals and molasses in continuous centrifugals has a major influence on sugar losses, separating efficiency and throughput. Several methods, which characterize screen quality in terms of the slot width, uniformity, per cent open area and the resistance to fluid flow have been assessed by Sugar Research Institute. These are a pho...

Anodes of 304 stainless steel have been processed by a continuous wave Yb fiber laser with a wavelength of 1.064 lm and subjected to 50 keV electron bombardment in order to determine the extent to which hydrogen outgassing is reduced by the laser surface melting treatment. The results show a reduction in outgassing, by approximately a factor of four compared to that from untreated stainless ste...
