Introduce you to understand the operation of air - flow ultra - fine pulverizer

Small mill in the process of experiments, researchers has been the key operation, operation is more difficult, so the basic situation is not in the general case, a lot of matters need attention, and to a certain understanding of small mill, then you have mastered many small mill operation procedure and using skills? Let me give you a detailed introduction:

1, small mill when unpacking the case, first examine equipment inside have been damaged in transit, and then put the high machine and auxiliary engine electronic control device in place, again through the main auxiliary pipe road, each of the apertures must be used when the flange assembly seal paint "iron anchor 609" liquid sealant, guarantee the sealing of the pipes and pipe flanges are each units at the same time with a grounding conductor is connected, and grounding, To avoid dust explosion caused by electrostatic spark;

2. Before trial operation of each single machine, check whether there are metal items in the machine. If there are, they will be excluded. Whether the bolts are firm, the tightness of the belt, the reliability of the protective cover and so on;

3, according to the following sequence of stable start each motor, close the air valve to start, grinder -> dust collector -> grading device -> screw feeder -> open the air door -> air closure;

4. After five minutes of empty operation, the operator should carefully observe the various instruments on the control cabinet and wait for the no-load current to be stable before feeding. After feeding, the current is not allowed to exceed the rated value of 32.6a, otherwise the amount of feed should be reduced to ensure the normal operation of the discharge electric can work regularly;

5. The screw feeder can be shut down in the following order -> the main grinding machine, dust collector and classifier can be stopped after running for five minutes -> air closers; 6. The stepless variable speed handle of the classifier can be manipulated to change the speed of the classifier wheel and adjust the products to be fine. If the product is required to have fine particle size, the speed can be increased, and conversely, the speed can be reduced, and the particle size becomes larger.

Pharmaceutical equipment is a small crusher machinery industry with rapid growth in recent years. It is also one of the few areas in which the domestic machinery industry as a whole still maintains good growth momentum under the situation of development difficulties. However, in recent years, the industry has encountered many difficulties in the process of attacking the high-end field, which is mainly caused by the lack of innovation in the industry for a long time.

As a technology-intensive industry, innovation should be the vitality of industry development. But due to the limitation of the level of development and technical capacity, the domestic small crusher industry innovation vitality is insufficient, especially in the field of high-end equipment, imitation is still the main means of production.

Experts believe that this is mainly due to the expansion of the domestic pharmaceutical industry, in the past decade, the domestic pharmaceutical industry has maintained a surprising momentum of development, the annual growth rate of more than 15% of the achievements of the small crusher industry market space. Therefore, the domestic small mill industry has formed a relatively complete industrial system and is a huge market size, and actively carry out the transformation and upgrading of the industry. It is reported that there are two main modes of domestic high-end pharmaceutical equipment production: one is the core components rely on imports, domestic equivalent to assembly processing; The other is the clone mode, which is the mode of introduction - mapping - drawing - assembly - improvement. As a result, domestic high-end pharmaceutical equipment is mainly imitation, the widespread existence of "copycat" phenomenon.

At present, the domestic high-end small grinder independent innovation step is to get rid of the import of core components and key technologies, from research and development to the market recognition, domestic high-end small grinder still has a long way to go. High-end pharmaceutical equipment can not be made by imitation. Due to the accumulation of high-end pharmaceutical talents and technology in China, the situation of large-scale import of high-end pharmaceutical equipment from abroad will not change in a short time.
