The manufacturing accuracy of hammer of ultra-fine crusher has a great influence on the balance of the rotor of ultra-fine crusher. The factory of ultra-fine crusher of traditional Chinese medicine generally requires that the quality difference between any two groups of hammers on the rotor should not exceed 5G. Therefore, the precision of hammer should be strictly controlled in the process of processing, and the quality of surfacing welding process should be strictly guaranteed, especially for tungsten carbide hammer.
Hammers should be installed every day with complete sets of hammers, which are not allowed to be exchanged freely between sets. Hammers are the working parts of crushers that directly strike materials, and are therefore the most wearable and frequently replaced parts. Hammer wear refers to the wear of the working angles of hammers. Hammer wear refers to the wear of the four working angles of hammers, and the hammers will be scrapped. The shape, size, arrangement method and manufacturing quality of the hammer of ultra-fine crusher have great influence on the crushing efficiency and product quality. The crushing effect of 1.6 mm hammer is 45% higher than that of 6.25 mm hammer and 25.4% higher than that of 5 mm hammer. The crushing efficiency of thin hammer is high, but its service life is relatively shorter. The size of the object and type of the hammer with multiple thicknesses should be different.
The factory of Chinese medicine ultrafine crusher considers that the arrangement of hammers is best to meet the following requirements: when the rotor rotates, the track of each hammer does not repeat; materials will not deviate to one side in the crushing chamber with the hammer moving (except for special requirements); the rotor is balanced, and there will be no vibration when running at high speed. The bearing is overheated and the bearing is straight. It affects the normal operation and production efficiency of the equipment.
During the operation of the equipment, the users should pay special attention to the heating of the bearing and the noise of the bearing parts, and deal with the abnormalities as soon as possible. The uneven two bearing seats, or the centrifugal rotor of the motor and the crusher, will cause the bearing to be impacted by the additional load, thus causing the bearing to overheat. In this case, the machine should be stopped immediately to eliminate the fault. Avoid early damage of bearings. Excessive, too little or aging lubricant in bearings is also the main cause of Bearing Overheating and damage.
Therefore, it is suggested that lubricating oil should be added on time and quantitatively according to the requirements of the use book. Generally, lubrication accounts for 70-80% of the bearing space. Too much or too little lubrication is not conducive to bearing lubrication and heat transfer. Bearing prolongs its service life. Too tight coordination between bearing cover and shaft, too tight or too loose coordination between bearing and shaft will lead to bearing. Overheating. Once this problem occurs, the friction noise and obvious oscillation will be emitted during the operation of the equipment.
