Ball Mill For Slag/Ball Mill Grinding Machine
Ball millis mainly used for material mixing ,grinding ,uniform product fitness ,save power.As well as dry milling and wet milling.The machine can according to production need to adopt different kinds of lining board, to meet different needs. The fineness of grinding operation, relying on the milling time control on its own. Start motor from decompression, reduce the starting current, its structure is divided into integral and detached. This product has less investment, compared with similar products and energy saving province electricity, novel structure, convenient operation, safty for use, stable and reliable performance, etc. It is suitable for general and special materials and grinding operation. Users can be based on material specific gravity, hardness, and according to production factors such as comprehensive consideration to choose the appropriate type and plate.
How to Control Noise of Ball Mill Grinding Machine/Ball Mill For Slag?
1. add acoustic shield
The technique is to cover up the roller of Ball Mill Grinding Machine/Ball Mill For Slag, the cover shell is made of metal. In order to achieve noise reduction effect, the inside is lined with sound-absorbing materials, noise reduction can reach 15 ~ 20dB. However, when using this method, large area is required, also there is much trouble in the maintenance and overhaul of equipment, the acoustic shield needs to be disassembled, which increases the workload of maintenance and overhaul.
2. set elastic layer at the bottom of the lining boards
The method is to eliminate the rigid connection between the liner and roller, after successful installation, noise reduction can reach more than 15dB. However, this method is not easy to handle, because the elastic layer itself is a vibration system. the impact of steel ball will change with the natural frequency of the liners, resulting in a greater amplitude. Only when vibration noise frequency is greater than the liner natural frequency will has a good effect. It would be counterproductive if the installation is not good, and the cost is very high.
3. simple dressing
This method uses blankets and other sound-absorbing materials to make curved partition plate fastened with bolts. but the bolts are not wrapped so it is convenient to repair. Because the absorption capacity of blankets and other materials for the low frequency noise is not strong, so the noise reduction of this method can only reach about 10dB, noise-isolation effect is not very satisfactory and the cost is higher than the method of adding acoustic shield. However, this method is convenient for maintenance and overhaul, and also does not affect the steel ball loading and other work.
