Raymond mill spindle and Broken Raymond powder machine wearing parts are many, but Raymond mill bearings are indispensable accessories. Users give us feedback, in the course of Raymond mill use, there will be easily broken bearings, mechanical Lei gave an analysis of the lower bearing broken reasons? First, the effects of excessive wear in mine broadband use, due to insufficient spring pressure when grinding hard materials, the upper part of the crusher often bouncing mill, leading to engine wear and damage. Spring pressure to determine the correctness of the use and production costs are directly related Raimundo. Spring pressure is too small, it will result in Raymond is not working properly. Conversely, the spring pressure is too large, it will cause a high production cost. Second, the strength of the spindle through insufficient strength calculation know, Raymond fitting spindle static strength and durability, are not guaranteed Raimundo machine normally lasting work. Especially in the over-iron, bending stress the risk section, most of which exceed the yield strength of the material. When Raymond Accessories spindle actual compression spring approach is often used to increase the spring pressure increases the crushing force. When this had iron spring was almost crushed state, not only often pull off springs, screws, and the spindle bear a greater load. At the same time overload the spring played a complete loss, crushers and therefore subject to greater damage. Furthermore, since the liner wear unevenly, product size uneven thickness. In order to obtain qualified product size can be adjusted to the extent of the port of discharge collisions, the number of such cards had iron and iron greatly increased. Above is a brief introduction to Raymond mill parts broken spindle causes and solutions, and I believe that through the above explanation, we will for the Raymond mill spindle broken parts have a more profound understanding of the reasons, so in the future The use of the process will be more attention to the cement clinker mill, to avoid breakage occurs. Lei Raymond mill roller when installing Notes to Raymond mill roller and grinding ring is the most important mill grinding apparatus. Material through the blade to the roller mill ring, are pressed through a powder. During use, due to the pressure roller grinding, friction material support reaction force, the material between the liner and the roller mill roll body and liner wear. Due to the interaction of materials and ground into the angle of shear stress caused by the roller, the roller mill hydraulic system in the pressure force when changing the roller installation should note the following: 1. A roller on the main motor side, several additional should be placed uniformly distributed. 2, the roller is placed on the disc is inclined 15 degrees, and use their rim center coincides with the grinding track center. 3, triangle pressure and the tension rod suspension frame structure sand slag mill, roller mill should ensure affordability uniformly distributed points evenly. 4, the frame size is not greater than the pressure deviation 3mm. 5, the gap hardening liner liner pressure adjustment frame with an upper body between should meet the design requirements. Pressure micro-grinding of high pressure spring is how the device works pressure micro-grinding and ordinary Raymond mill is the same, but the high-pressure micro-grinding grinding device mounted 1000-1500 kg pressure hyperbaric spring, when the machine work under high pressure spring and centrifugal force, roller close to the grinding ring rolling, rolling pressure than Raymond mill under the same conditions, 1.2 times higher output can be increased by 20% -30% of zircon sand powder machine When the grinding roller and grinding ring after a certain wear, high-pressure adjustment spring length, maintaining a constant pressure between grinding roller and grinding ring, thus ensuring stable production and fineness. The high pressure of the spring on a high-pressure micro-grinding installation methods are generally in the bearing chamber and plum frame these two components up to complete, plum shelves is the need for open heart-drilled holes for connecting screws used to wear. In the above there is a spring bracket fixed above have a fixed bearing housing a spring seat, which form a very important fixtures, high-pressure micro-grinding is an integral part.
