Problems 1. The difficulty of particle size control is large, and the internal crushing load is aggravated. Because the large particles (more than 3mm) return to the machine head, the system granularity is too large. In order to ensure that the particle size index has to reduce the amount of shot, the crushing adjustment is performed. The time spent in the second time is about 5h. In the adjustment process, the appearance of the finished product is often irregular, and it is difficult to screen out the fine powder. The product quality (granularity) cannot be guaranteed. After observation and analysis, we believe that this problem is caused by poor classification of the internal classification cone. The large particles return to the machine head, continue to coat the bond, and repeat. The internal crushing load is aggravated, and the motor burns out due to overload.
2. The machine head is easy to materialize. In severe cases, the melted material enters the labyrinth seal ring (the function and characteristics of the carbon fiber fiber packing seal packing), the production cannot be carried out, and it is forced to stop the cleaning, which takes time and effort. This problem is caused by unreasonable internal material returning position, easy to be directly affected by high temperature, dehydration and melting.
3. The production at the time of Taiwan is low, and the production load of 110t or more per day cannot be adapted. The reason is that the system granularity fluctuates greatly, the fine powder is too much, and the trunk line is often blocked, which does not reach the long-term continuous operation, which limits the potential capacity of the device. .
The effect after the transformation 1. The original in-machine grading cone was cancelled, and the grading device was redesigned and installed, which completely solved the drawbacks of the large particle returning machine head, reduced the internal crushing load by 40% to 50%, and increased the Taiwanese output. 30%, under the normal conditions of slurry index, the daily output can reach 150t or more, the operation is labor-saving and worry-free, and the trunk line fan, dust collector and Other trunk lines can also achieve continuous operation for more than 60 days without clearing the plug, achieving long-term continuous operation. .
2. According to the characteristics of strong fluidity in the machine, we designed and installed the material distributor in the tail screen division to increase the effective screening area by more than 90%, thus ensuring the product quality (particle size), and the 1~4mm particles can be long-term. Stable at more than 90%, and even and smooth, no fine powder.
3. Designed and modified the blanking position and material movement direction of the spiral channel in the machine. In addition to the machine head material, the continuous operation of the device is guaranteed, saving maintenance costs.
