Two e10.3 is enough for normal use
e10.3 theoretical power consumption is 2400W (measured: e10.1 power consumption is about 2200W, e10.3 power consumption is 3300W
at present, e10.1 model is more popular in the market. The old E10 is also good. Wing bit e10.3 as far as the current market is concerned, the heat is not high, mainly in terms of power consumption. It often appears that two 1800W power supplies can not afford one e10.3, and the computing power is not enough. E10.1 is more suitable for mining because the power consumption amplitude is not very large
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 The experimental results show that the noise increases about 3dB (a) when the gear load doubles at low speed and low load (other conditions are the same). According to the use characteristics of grinding equipment, the gear load has little change, so it has little influence on the noise. However, the problem of dynamic balance of grinding roller is not paid enough attention. Due to the non-uniformity of the roller mass, the runout deviation of the roller surface to the two shaft diameters and the coaxiality deviation of the two shaft diameters, it is inevitable that the mass rotation center and the motion rotation center do not coincide, resulting in dynamic imbalance and periodic impact vibration. The unbalanced moment of inertia causes the periodic impact dynamic load of the gear through the rigid shaft, which increases the gear noise. Therefore, we can improve the quality requirements of the roller body to ensure the smooth movement of the roller body, rece the inertia impact, and control the tolerance of the roller body unbalance within the specified value
Improve the installation accuracy of roller bodye 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
With regard to the question of what kind of proction line equipment should be used for the 325 mesh cooked bauxite mill, the first thing to understand is the equipment required for the 325 mesh cooked bauxite mill. Then, what are the principles for the selection of these different equipment? Combined with these aspects, when the 325 mesh cooked bauxite mill is configured, The main proction line equipment that can be selected are as follows:
first of all, the proction of cooked bauxite mill must be inseparable from the mill, which requires 325 mesh. Therefore, the mill equipment that can be selected include vertical mill, suspension roller mill, etc. these different mills can meet the processing requirements of 325 cooked bauxite. In addition to the mill, when the cooked bauxite is processed, Also need some auxiliary equipment, such as belt conveyor, feeder, etc., these different equipment together group mature bauxite processing proction line
Secondly, in addition to the selection of equipment type, we should also pay attention to the proction requirements, such as the requirements for proction capacity. Generally speaking, different proction capacity requirements lead to different proction line equipment to be selected. At the same time, we also need to pay attention to the cost input of the 325 mesh proction line equipment, As well as the manufacturer's after-sales problemsthis paper mainly introces the problem of which proction line equipment is good for the 325 mesh of cooked bauxite grinding. The analysis of this problem is mainly carried out from two aspects: one is the problems of the 325 mesh of cooked bauxite grinding proction line equipment, the other is the principles to be followed in the selection of these proction line equipment, Combined with these aspects, we can choose the appropriate proction line equipment for cooked bauxite grinding. For other questions about the proction line equipment for 325 mesh of cooked bauxite grinding, please consult: www.shibangchina.com Hope to help you
tailings sand is mainly composed of soil and mineral powder, with uneven particles and many bad soil components
mineral powder is a kind of mineral powder mainly composed of calcium hydroxide, which is obtained by grinding limestone. Its physical and chemical compositions are very different
If tailing sand is used to replace mineral powder, the grade of concrete will decrease and the performance will be seriously affected
the milling process plays an irreplaceable role in the development of instry, especially in building materials, coal mines and mineral powder manufacturing instry. Therefore, the technical performance of the mill has become the focus of attention. Raymond mill is a large-scale grinding machine, the feed particle size can be less than 100 mm, after grinding, it can pass through the ten thousand hole screen, and the output is generally more than one ton per hour. Shanghai corerick mill is very good.
