Vertical milling machine is the key equipment to processing stone material. It is Suitable for grinding various ores and other materials and are widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal processing and glass ceramics production industry.
Following SHANGHAI CLIRIK in the long-term production practice process carefully developed several methods to reduce the noise of the Vertical milling machine, and defects and remedies of vertical milling machine:
1, set the elastic layer. Placement of a heat-resistant soft rubber pad between the inner surface and the lining of Vertical milling machine, to prevent overheating of the soft rubber pad, and between the liner and a soft rubber mat of Vertical milling machine placement thickness of 10 on a 15mm industrial felt will enable the mill noise is reduced to less than the allowable standard.
2, the outside of the drum wall insulation layer wrapped; Dressing mill roller wall with a layer of industrial felt, for surface protection, steel bolts fixed in the the drum outer wall, the sound insulation value will greatly improve. The roller ends do the same, good drum wall bandage seams sealed; sound insulation effect is also likely to increase.
3, with a rubber liner in place of the manganese steel liner, the noise level can be decreased by 9dB (A), the spectral characteristics are also changed by the high frequency to low frequency.
4, An increase of acoustic enclosures; Steel frame, thin steel shell, to within wiping damping layer and fill ultrafine glass wool or other sound-absorbing material, the entire Vertical milling machine closed.
5 establish sound insulation between the anti-vibration operation, the workers in the control room for remote operation and instrument monitoring, with the outdoor to conduct regular inspections to reduce workers' exposure to strong noise and vibration.
6, during the application of the vertical milling machine, some personnel shall be arranged to take responsibility of management. The operators must be qualified with the required technical knowledge. Before the installation of the vertical milling machine, the persons related to the operation should receive technical training and fully understand the operating principle, performance a regulations of the vertical milling machine.
7, In order to guarantee the vertical milling machine in a normal working state, a safety operation system for the maintenance of the equipment must be established. Only in this way can the vertical milling machine be guaranteed to have a long-term and safe operation. Meanwhile, it is necessary to have the required repairing tools, lubricant and grease, spare parts and accessories.
8, after some period of running, the vertical milling machine should receive an examination and repairing.
9, If the Grinder roller are replaced by the new ones because of their application time surpassing about 500 hours, all the rolling bearings in the roller sleeves must be cleaned, and the damaged parts should be replaced. The oiling tool can be either a manual oiling pump or grease gun.
