Magnetic Separator Should Note the Following Points

The magnetic separator is one of commonly used preparation equipments in magnetic separation factory. It has dry and wet two types. According to types of magnets, it can be divided into permanent magnet type and electromagnet type. It is also can be divided into strong magnet type, middle magnet type and weak magnet type according to the magnetic field strength. Different magnetic separators have different characteristics and performance. 1, to maintain good lubrication condition is to extend the service life of an important part. Open gears should be sufficient lubricant, bearing cover the filling hole, at least every three months oiling once. 2, regular checks of cylinder wear layer. The loosening or breakage shall promptly repair, repair, breakage at the…

Immobilization of Amylase on Magnetic Nanoparticles

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine, Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show the best result. Finally the immobilization efficiency was tested by determination of protein concentration in a solution before and after mixing with the magnetic nanoparticles. Introduction In the last two decades, new terms with the prefix `nano’ have rushed into the scientific vocabulary; nanoparticle, nanostructure, nanotechnology, nanomaterial, nanocluster, nanochemistry, nanocolloids, nanoreactor and so on….

Magnetic Abrasive Finishing of Thick Cylinder Tube

Abstract Magnetic Abrasive Finishing (MAF) is an advanced finishing method, which improves the quality of surfaces and performance of the products. Surface is finished by removing the material in the form of microchips by abrasive particles in the presence of magnetic field. The material is removed in such a way that surface finishing and deburring are performed simultaneously with the applied magnetic field in the finishing zone. The mechanism of super finishing in any finishing process is widely focused by the knowledge of forces involved in the process. This paper deals with the detailed parametric study in super finishing of stainless steel SUS 304 thick steel tube. Statistically designed experiments based on Taguchi methods show that weight of abrasive, Revolutions…
