Crusher rotor bearing wear on-line repairing technology

Hammer crusher is also called dry broken, it is used for crushing and drying soft and abrasive materials, such as gypsum, chalk, clay, slurry filter cake, etc. , such as the industrial by-product gypsum, flue gas desulfurization gypsum stop scattered, drying and calcining, the machine consumption of high efficiency, low energy consumption, at the same time of drying is scattered and broken. Carbide slag cement is used calcium carbide slag instead of limestone consumption cement clinker, calcium carbide slag cement has the advantage of, on the one hand, the application of carbide slag, lowered its long-term storage occupation of land environmental impact, such as, save containing limestone resources on one hand, on the other hand reduced CO2 emissions, is conducive to energy conservation and emissions reduction. In the synthesis phase, the synthesis of ordinary Portland cement clinker is stop limestone, and is the synthesis of calcium hydroxide, calcium carbide slag cement so his lower CO2 emissions. But due to the fine carbide slag compare, grinding power is relatively low, due to high demand drying calcium carbide slag water content, so application of carbide slag common used drying hammer crusher. Hammer type drying crusher rotation of the rotor material will break up, hot material drying, air flow will have broken with dry material to the separation chamber, fine powder into the cyclone tube separation, then coarse particle back into the hammer crusher broken again. From the perspective of the instance of repaired, some enterprise configuration drying PCG4828 hammer crusher, rotor diameter of 4800 mm, 2800 mm long, drive shaft and bearing when negative machine full load, good operation and the shaft bearing and equipment operation has a great relationship, it directly affects the using life and availability of the machine. Drying broken shaft and bearing is based on a set to fixed, not only accept high temperature and in the process of operation, frequent shock and vibration as the growth of the cycle, bearing and set the indirect impact of axes, overnight the original fastening force as metal elements such as fatigue, contraction and loose, fit clearance, bearing set under high load overloading and spindle axis wear, formed by the relative motion. Hammer stone drying crusher: type PCG4828, specification & Oslash; 28 mm * 4800 mm, 120 t/h to, the speed of 138 r/min, 480 h9 diameter of axle, bearing a 310 mm wide, bearing model 23184, 600, import set fit flue gas - The 120-730 ℃, export flue gas 100 ℃, bearing temperature 60 - 80℃。 Sauvy industrial carbon nano polymer materials to repair dry shaft wear technology based on drying breaking shaft neck size must be the position of the sauvy caliper repair process separation set set of repair, site operation steps are as follows: 1, and enterprises to provide drawings according to the equipment structure before and after the preliminary judging adopt bearing a shoulder not wear stop positions; 2, field USES outside micrometer measuring front axle shoulder positioning size, processing the corresponding caliper; 3, will stop in addition to the disposal of oil bearing a fix position; 4, used calipers along the datum is concentric; 5, the application of set of fitting, certain fundamental dimensions; 6, mixed right amount SD7104 data, and the average closely coated in the fix position; 7, set set of the lining after cleaning brush besmear SD7000 release agent; 8, will increase the size set set of read and hurtling device in shaft repair parts, the application of set set of chong tooling stop size recovery, appropriate lock tight sleeve nut; 9, data after curing, removing set set, check fix size; 10, the basic size of the defect parts again after repair coating SD7104 data, size until recovery; Continue to apply after 11, size recovery set a stop fitting, eliminate high until the assembly in place; 12 and repair parts coating SD7104 data again, set set of brush besmear after demoulding agent device in place; 13 heated to 120 degrees Celsius, bearing according to the request and fastening nut assembly, measurement of clearance.
