As we know, the rotors are very heavy and have high rotation speed, so the unbalance of rotors will cause strong vibration of impact crusher, and lead to the rapid rise of bearings temperature or even burn out.Reasons Analysis: In the operation process of impact crusher, there is strong vibration and loud noise, the temperature of rotor bearings rises rapidly, which will lead to the bearings burn out and the impact crusher cannot work normally. If we do not take measures in the installation process, it will cause the unbalance of rotor weights. Since the blow bars in impact crusher generally adopt casting elements, the casting and working accuracy is relative low, so the weights of the blow bars differ greatly.
As shown in Figure 1 and Figure 2, a kind of mill disc for quartz sand processing stone muller providing for the utility model, comprise outer coil 1b, in outer coil, be provided with the interior coil 1a with its coaxial cooperation, between interior coil and outer coil, be also provided with back-up ring 4, between back-up ring 4 and interior coil 1a, outer coil 1b, be respectively equipped with a circle body, each circle body is all that the arc stone roller saddle 2 of being made by one group of quartzite material forms, and between the adjacent stone roller saddle of each circle body, is equipped with dividing plate 3.
Thus, only sufficient make-up water is required to compensate for water evaporated or otherwise lost in the process, and this amounts to little more than the difference between the moisture content of the raw input and the moisture content of the product and refuse produced.This process has certain advantages. As a result, essentially all of the water utilized in the process can be retained and recirculated. Accordingly, the process is particularly desirable from an environmental standpoint since the process can be self-contained and operated with minimal fresh water requirements and without discharging any noxious effluents. For instance, the centrifugal separators 250 and 270 are capable of separating from a slurry a solids fraction down to five microns in size.
80% silica, and represented 70.36% Fe and 6.12% Fe and 15.The underflow product from this froth flotation step was a concentrate containing 65.16% silica. The flotation froth was made up mostly of magnetite-quartz middling grains containing 58.85% by weight of the cell feed.
Polishing operation is implemented to the hot recycling sand obtained from hot recycling process.In polishing operation, hot recycling sand surfaceCarbide be removed, and the molding sand that therefore gives up can be recycled as artificial sand, and the artificial sand is used as the raw material of mould.
It can be found that the wear debris is mainly composed of elements Ni and Fe, and there are also certain contents of elements O, Ti, B, Nb and Mo, indicating the formation of oxides and the detachment of TiB2 particles.%, the number of large-sized lamellar debris is gradually reduced, and the number of dense and fine granular debris is increased, of which the wear debris of coatings TB20 and TB30 shows a relatively small average size, indicating the wear resistance is enhanced and the wear mechanism is changed from multiple-plastic deformation wear to abrasive wear and micro-cutting wear (Figure 15b,c,e). When the TiB2 particles content increases from 10 to 30 wt. It can be seen that the wear debris of coating TB0 exhibits typical large-scale lamellar characteristics, indicating severe plastic deformation (Figure 15a).Figure 15 shows the SEM images of wear debris of coatings with different TiB2 particles content. When the TiB2 particles content increases to 40 wt.%, the number of large-sized lamellar debris increases for the micro-brittle fracture wear is dominant in the wear mechanism, of which abrasive wear also exists for the small amount of granular debris (Figure 15f). The EDS surface scanning analysis was carried out for region D in the wear debris of coating TB40, and the results are as shown in Figure 15d.
