| The grinding barrel material in sand mill among this industry most many manufacturers are using the grinding barrel made of stainless steel (304), in the stainless steel material which can be divided into many kinds, such as: Jiangsu, Chongqing and Qinhuangdao, their equipment is mainly made of 304 stainless steel to make the grinding barrel if you do, the water will appear rust, in the eyes of everybody that the 304 stainless steel is generally not rusty, but their equipment in the grinding of the time or for a period of time where the equipment does not work, the water inside a long time, there will be rusty the reason is that the 304 steel traces, which contain an element called nickel, nickel content of 304 steel is the highest in 8, the steel will not rust, they used 304 steel mainly containing 4 nickel, so the grinding time will be The phenomenon of rust, if you will be grinding white materials gray (black), titanium blue if using stainless steel barrel grinding will appear dark blue (grinding the longer the more reflected the deep blue color, the reason is when the stainless steel barrel and pure zirconia beads occurred rub zirconium beads hardness is higher than the hardness of stainless steel, so the more serious wear barrel) the same with red when the barrel body of the grinding stainless steel will also change the phenomenon of the reason. So when many manufacturers to the user with a selection of grinding mesons are usually used glass beads and ordinary zirconia, so wear of the grinding barrel is relatively small, but there will be what kind of shortcomings, such as you do now is material requires about 0.2um-0.5um (200 nm -500 nm), so the fineness is relatively high, if using stainless steel barrel or zirconia glass, as ordinary mesons, there will be a long time down material fineness, will change, at the same time, the company equipment is mainly used to wear resistant alloy steel imports is a kind of wear-resistant alloy steel imported from Sweden is a name of a chain in the world the wear resistant alloy steel, grinding meson we use is pure zirconia imported beads containing zirconium content above 95, the proportion is 4, the ratio of glass beads The weight is about 2 in the ordinary zirconium beads at about 2.5. When the material in the grinding barrel inside the grinding is mainly meson pure zirconia grinding barrel inside the beads and material impact with the barrel friction to a grinding effect, if the proportion of the more abrasive meson impact strength is greater, grinding fineness is easy to down, the proportion of light intensity of the impact on the smaller the fineness is difficult. The grinding barrel material: rotor in the process in terms of the above sand mill was divided into two kinds, one is the grinding disc disc, second rotor grinding barrel and pin rod pin rod of the sand mill in the first disc, the barrel wall of the barrel body is smooth without what other form like, with grinding wheel in the rotor, so the effect is to have certain limitations, however, pin mill is mainly embodied in the wall of the bucket rod d above the barrel body, the rotor is above rod (rod material mainly is Ding Ding, tungsten steel) process will this grinding to improve a lot, mainly sports in the impact strength when grinding material and zirconia beads in the grinding barrel inside the grinding disc, meson zirconia beads in the barrel body which is mainly straight back and forth movement, so the grinding fineness above will take a long time, in the pin mill. Art is a linear motion and linear motion of the two, the line speed per second is in the 12m/s (mainly refers to the speed of the movement of zirconium beads in the barrel). Therefore, the pin rod type sand mill is much more effective than the disc sander. The material and grinding meson (zirconium beads) separation device: when the separation material and grinding medium in horizontal sand mill which is mainly with the interval separating device, the interval separating device is mainly composed of static ring and moving ring is composed of two parts, static ring is mainly on the mechanical seal mounted on the side is not moving, moving is this side and contact material, the main material of the static ring and moving ring is made of pure tungsten, the gap between them we are according to your material requirements such as to adjust the fineness of the required fineness is 200 nm to 500 nm, then we will be the gap between 0.1-0.4mm mm (we give you the equipment is the modulation of the 17 wire is 0.17mm), the smaller the gap interval separating the grinding material meson is smaller, generally 3 times greater than the ground meson separation gap, so we are here to give you The size of the grinding meson is 0.6-0.8 pure zirconia bead proportion is in the 4.0. so that the fineness of the material grinding has a very good effect mainly reflected in the time of the fineness of the fineness of the relatively fast output. The cooling effect of mechanical seals and equipment company of mechanical seal is used in Germany imported brands of no leakage, general service life of 8 thousand hours or more, due to the sealing lubrication itself is very good, do not need to rely on external help such as lubricating oil lubrication, thus changing the traditional ordinary mechanical seal oil cooling, the most critical machinery the seal circulating liquid miscible with the grinding material solvent or water, to avoid pollution products in the production of the accident, cause unnecessary economic losses. The main body of the equipment is the use of water cooling cooling, mainly in these aspects of cooling: mechanical seal, grinding barrel body, front plate, shaft four cooling. Production efficiency: because the structural design is reasonable, special double order tungsten rod pin (rod d) design, with high energy zirconium grinding beads, high efficiency, but also can according to the yield of double single gap discharge |
