Hydraulic mills have gradually been eliminated by air pressure mills because of many unfavorable factors such as oil contamination and poor operating performance. However, many powder factories are unable to replace them due to financial constraints. Here are some examples of low-improvement improvements for your reference.
1 Adjust the technical characteristics of the surface of the feed roller The traditional feed rollers are trapezoidal and have shallow tooth grooves. For large pieces of bran, feeding is not ideal. It is recommended to feed the Wuxi Buhler MDDK air pressure mill. The material roller parameters, on the heart of the thread feeding roller on the milling machine to scrape the surface of the milling machine, after making the feed roller teeth like spike-like, with a strong material, feeding evenly. It should be noted that after the feed roller is replaced, pay attention to the safety of the hand when picking. And need to adjust the feed roller speed, so that the material accurately into the grinding area.
2 Replace the roller bushing for the bearing to change the sliding friction to rolling friction. Some flour mills have made changes in business. The grain mill also has this service. One of the changes is that it can reduce oil pollution. Sometimes the seal of the bushing is damaged, or the oil is overfilled. The oil will flow into the grinding bowl and pollute the flour. At the same time, using this method can also reduce power consumption and improve economic efficiency. The second is to avoid grinding roller swaying. When grinding, it can reduce leakage at both ends of the roller. The third is to reduce the radial runout of the roller, which helps to improve the grinding accuracy.
3 Replacing the differential transmission The chain transmission is a toothed belt transmission, which can greatly reduce oil pollution, noise, and improve the speed ratio accuracy. Conducive to equipment hygiene and equipment maintenance, taking into account the cost, you can buy out old parts of the mill, the effect is as practical.
4 Appropriately increasing the speed of the grinding roller For the manufacturers who want to increase the flour production, the rotation speed of the original roller can be increased from 450-500r/min to 550-600r/min. This practice can increase economic efficiency and reduce production costs. The method is simple, just replace the motor pulley.
5 The slag tail mill can replace the tooth roller with the light roller. The loose powder machine The loose powder machine can be installed on the ground floor, which can be easily maintained. It can also be mounted on the roof. Its advantage is that it is not easy to block. After the change, the quality of the flour will be greatly improved, and the ash content of the flour will be significantly lower than that of the roller mill.
6 There are some less mature ideas, we have not yet tried specifically, such as the use of automatic feeding system for hydraulic milling machine is not good, you can consider the use of variable frequency motor drive. Demolition of the hydraulic rolling and rolling mill, and installation of large-diameter cylinders in the general adjustment position. After such a mill has invested more than 10,000 yuan, it can completely get rid of oil pollution, and it is comparable to a pneumatic grinding machine worth more than 100,000 yuan. .
