Excessive Noise Stone Mill Flour

Date: 2019-12-19 14:39:29 Source: Click:
The processing efficiency of stone flour milling machine has been greatly improved compared with the traditional flour milling machine. The processed flour is of high quality and the pasta flavor is tangy. The stone milling flour machine produced by Henan Industry and Food Machinery Co., Ltd. is well received by customers in the flour industry. However, if the noise of the stone mill is too loud, then it is unqualified and cannot be put into production.
The specification of the stone mill flour mill is less than 85 decibels. If the noise reaches 90 decibels, it means that the flour mill noise is unqualified. There are three reasons for this large noise, namely the poor accuracy of the stone mill flour milling machine; the second is the motion parameters. Incorrect selection; again, the operation process is inappropriate.
1. The processing accuracy of stone flour milling machine is poor, mainly manifested in the grinding roller processing accuracy, gear processing accuracy, and poor installation accuracy of the whole machine. The main parts of the flour machine are: casing, grinding roller, bearing seat and gear. The accuracy of these parts has a great impact on the performance of the whole machine after installation. As far as noise is concerned, the processing accuracy of grinding rollers and gears has the greatest influence. If the shape error of the grinding roller exceeds the requirements specified in the skill file, the roller body becomes an irregular cylinder. The flour machine with such a grinding roller cannot work well during operation, and it also produces an uneven sound. , Noise is high and power consumption is high. At present, the transmission between flour mill rollers is basically geared. Generally, the operation of flour mills is caused by abnormal gear meshing. If the accuracy of processing and installation cannot be guaranteed, the operating noise of flour mills is difficult to decrease. . For this reason, each enterprise must strictly control the processing accuracy and installation accuracy of product parts during the production process.
2. The operation technology of the stone milling flour machine is not suitable. In order to improve the production power of a single enterprise, a small roller roll distance and a small feeding amount are used. In this way, the grinding between the rollers is added, and the sound is loud, especially when the accuracy of the rollers is poor.
3. The selection of motion parameters is improper. The main manifestation is that the rotation speed of the grinding roller is too high, which causes the noise of the stone flour mill to increase naturally.
