Weinan mineral powder mill

1. First of all, I want to understand what you are grinding
2 and how long will it take for you to grind 300000 tons of mineral powder? You have to refine it
3 your grinding requirement is to what extent
only when I understand the above three points can I give a complete answer and find the right medicine to the case
generally speaking, the high-pressure roller mill and ball mill are used now, which are the most mainstream grinding equipment

I specialize in mining machinery and equipment, including high-pressure roller mill, ball mill, magnetic separator, jaw crusher, vibrating screen, beneficiation shaker, belt conveyor, flotation machine, dryer, classifier, electromagnetic vibration feeder, spiral chute and other grinding and beneficiation equipment and supporting machines. As well as waste heat power generation project and fan procts, welcome to inquire and negotiate.

2. Fluorite mill configuration is very diverse and flexible, the specific configuration depends on your proction requirements. 120 mesh fluorite powder (hcq1290) proction line fine powder mill high-yield flexible configuration, by the host, feeder, classifier, blower and other combination configuration, specific you can see

3.

Noise control and noise rection measures of mineral powder mill to control the noise of mineral powder mill, the main noise source (gear transmission system) and influencing factors of mineral powder mill should be analyzed first, and different methods should be adopted for comprehensive control according to different situations

Try to eliminate the "design noise"

through the comparative analysis of the noise spectrum of mineral powder mill under different working conditions, it can be seen that the peak value of noise sound pressure level occurs in the area where the second and third harmonic frequencies of gear drive impact frequency and system natural frequency (gear meshing frequency) are equal or close, which is caused by resonance and amplitude surge. The peak value appears periodically. But because of the high frequency of the peak, it is often ignored. In fact, the noise of the mill is formed by the combination of these different peaks in the high frequency band. In order to avoid these peaks, it is necessary to change the motion parameters, avoid resonance, and eliminate the noise which is not caused by the quality of parts manufacturing and installation

2. Improve the gear manufacturing accuracy

the reason for the noise in the gear system is that when the gears are meshing, the impact and vibration between the gears occur, and the sound and noise are generated through the energy conversion of the medium. Its occurrence (sound pressure level) is related to amplitude, frequency characteristics and natural vibration frequency characteristics of the system. The direct way to rece noise is to take measures to the noise source to minimize the impact. When the mill is working, the center distance of a pair of meshed gears will change with the adjustment of the rolling distance of the mill roll, and the overlap degree will decrease with the increase of the rolling distance. The driven gear will inevitably proce speed fluctuation, instantaneous acceleration and impact. To rece the noise, it is necessary to rece the impact, improve the stability of gear meshing motion and improve the gear machining accuracy. When machining gears, we have worked out strict technological proceres. At the same time, under the condition of not affecting the gear strength, the material with better toughness should be used

completely eliminate the noise of grinding equipment from the following aspects. Mainly through the following points for you Improve the installation accuracy of roller body

e to manufacturing or installation reasons, the axis line of fast and slow roller of stone grinding equipment will be inclined relatively. In addition, when the clearance between the gear and the journal is too large, it is easy to proce eccentricity, so that the rotation center is not consistent, and the motion interference will occur in the meshing of the gear teeth, resulting in the additional dynamic load of the gear. Under the action of periodically changing additional dynamic load, the gear pair also has motion impact. Because the gear is installed on the roll shaft, the impact frequency is basically consistent with the gear meshing frequency and the dynamic unbalance impact frequency of the roll body. As a result of impact superposition, the gear noise presents periodic peak sound pressure level. In order to control the noise, we strictly control the influence of the installation error. The parallelism of the axis lines of the two roller bodies is improved and kept in motion

3. Standardize the operation proceres,

control the environment conditions of the grinding equipment. The main processing objects of the grinding machine are wheat and other materials with similar particles. From the results of many performance tests, it is found that in addition to the influence factors of the machine itself, the influencing factors of the noise index of the mill also include the operation method, the characteristics of the grinding materials, the environmental conditions and so on. Therefore, the implementation of standardized operating proceres is one of the effective measures to rece noise. According to the principle of sound transmission and reflection, it is necessary to improve the working environment of the mill equipment
