block neodymium magnets are Sumitomo Special Metals Corporation Sagawa, who live invented in 1982, known by its chemical formula, etc. which is mainly composed of neodymium, iron and boron chemical element constituted,NdFeB magnets can be divided into two kinds of sintered NdFeB and Bonded NdFeB. Injection molding is actually bonded, and sintering is heated to high temperatures by vacuum molding! super neodymium magnets
Generally small at room temperature paramagnetic susceptibility substance magnetic plate separator is about 10 ^ -5. Generally contain an odd number of electrons of atoms or molecules unfilled electron shell of atoms or ions such as transition elements, multi pole ring magnets rare earth elements, lanthanides steel and other metals as well as aluminum platinum are all paramagnetic substances.
And strictly positive with the external magnetic field H is proportional.Magnetic paramagnetic substance in addition to the H-related things, samarium cobalt magnets depends on the temperature. H with its magnetic susceptibility is inversely proportional to the absolute temperature,Where magnet filter is a constant depending on the magnetization called the Curie paramagnetic substance and the magnetic moment size.
The main characteristics of paramagnetic substance is applied regardless of the existence of atoms inside a magnetic field in the permanent magnetic moment. But in the absence of an applied magnetic traps due to the atomic paramagnetic substance random thermal vibrations do not seem macroscopic magnetic orientation in an applied magnetic field magnetic moments of each atom relatively regularly show very weak magnetic material. Magnetization and external suspended magnet in the same direction
ndfeb ring magnets magnets are currently found in the commercialization of the highest performance magnets, known as magnetic king, we have extremely high magnetic its biggest energy product (BHmax) higher than the ferrite (Ferrite) more than 10 times. Machining performance itself is also very good. Operating temperature up to 200 degrees Celsius. And its hard texture, stable performance, good price, so its application is extremely broad. But because of sm2co17 magnet its chemical activity is very strong, it must deal with its surface coating
Iron-boron magnet strength: material grades are N35-N52; according to the specific requirements of processing a variety of shapes: circular, square, drilling, magnetic tile, magnetic grates magnetic, convex, trapezoidal; despite these advantages, but the surface is easy to Health rust, so usually require some protective surface treatment: nickel, zinc ,, gold-plated, epoxy resin and other applicable environmental temperature NdFeB magnets is below 200 degrees, mainly used in electronics, electrical appliances, packaging, electrical, toys, inline magnetic filter leather goods, auto mechanics, etc.
After the high-pressure pump start, Magnetic Grate when the pressure reaches 16 ~ 18MPa, the ball floated Simplified 0.13 ~ 0.18 mm, then you can start the mill. 15 min later, the ring gear and small Adequately lubricated gears, mill at 0.4 MPa of low pressure lubrication operation. Because job working operation or electrical problems, and sometimes high-pressure oil pressure does not reach a predetermined Oil pressure or high-pressure pump there is a problem to force the mill started at a lower pressure. At this point the host mill bearing pad is closely integrated with the state of the hollow shaft, friction Large, if start mill, not only easy to scratch pad, and a small gear due to localized sudden impact, prone to the phenomenon of broken teeth.The second reason for broken teeth: No disk drive or disk drive enough time
multipole ring magnet medium and the opening of the drum wall was excluded from the drum, and the solid particles are trapped in the filter medium, and then the formation of cake layer, discharge drum in the spiral push,magnetic separator the centrifugal filter the entire feeding, separation, liquid, discharge is completed automatically and continuously.Magnetic separator has been widely used in machine tools and automatic line (not more than 100MM scroll chip and bulk chip, and the piston ring machining nodular cast iron used), samarium cobalt magnets it is water, oil cooling machine tool coolant system separating ferromagnetic material chip important chip removal device, especially with the magnetic line chip removal to deal with cast iron scraps
