Large mineral powder mill

1. The high temperature and fast drying process is adopted in the ore powder dryer proced by Chengxiang machinery, which successfully combines the advantages of hot air slot rotary dryer and air flow dryer. Under the action of high-speed rotating blades, the materials are thrown, smashed, and dispersed in the body. At the same time, they are fully and effectively contacted with high-temperature hot air, which strongly carries out convective heat transfer. Thus, the mass and heat transfer process is realized, and the continuous two-stage efficient drying of materials is realized< Second, proct features:
(1) the drying process of the ore powder dryer is advanced, adopting high-temperature rapid drying process, with large heat transfer coefficient, high thermal efficiency and high drying intensity
(2) the combination of high-speed stirring drying and air flow drying can fully disperse viscous materials, greatly improve the contact area between materials and thermal medium, which is concive to the drying process
(3) special scraping device is used in the ore powder dryer to avoid the phenomenon of material sticking to the wall
(4) wide application range, simple operation, small maintenance and stable proct quality
(5) the mineral powder dryer is specially designed for drying mineral powder, with variable rotating blade angle and adjustable rotating shaft speed
(6) the upper part of the ore powder dryer body is equipped with a wet material reflux layer, and the airflow dryer is equipped with a special mixer
three equipment composition and working principle
1) the complete set of equipment of mineral powder dryer is mainly composed of drum crushing dryer, combustion furnace, feeding screw, discharging screw, conveying pipeline, st collector, air shut-off device, inced draft fan, control cabinet, etc
2) working principle: the ore powder is directly sent into the drum crushing dryer by the feeding screw, which is repeatedly picked up and scattered by the plate on the inner wall of the drum. After being dispersed by the crushing device, the material fully contacts with the high temperature medium with negative pressure to complete the heat and mass transfer process. Due to the inclination angle of the drum and the effect of the air diversion, the material moves slowly from the feed end, and is discharged by the discharge screw after drying. The tail gas is discharged into the atmosphere after being removed by the st collector

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
