How to do a good job of mill maintenance work?
The mill is widely used in metallurgy, building materials, chemical industry, mining and other fields of mining products and materials grinding processing.Common processing materials are calcite, limestone, marble, potassium feldspar and so on.In order to extend the service life of the mill, my company after years of experience summary for your reference:
First of all, in the process of mill use, should be fixed personnel responsible for watching, the operator must have a certain technical level, the operation of the mill before the installation of the personnel must be closed technical training, so that it understands the principle of the mill performance, familiar with the operating rules.In order to make the mill work normally, the equipment "maintenance and safe operation system" should be formulated to ensure the long-term safe operation of the mill. At the same time, necessary maintenance tools and grease accessories should be provided.
Secondly, after a period of use of the mill, maintenance should be carried out. At the same time, the grinding roller, grinding ring, spade-knife and other wearing parts should be repaired and replaced. The connecting bolt and nut plug of the grinding roller device of the mill should be carefully checked before and after use to see whether there is loosening phenomenon and whether the lubricating oil is added adequately.When the roller device is used for more than 500 hours, the rolling bearings in the roller sleeve should be cleaned and the damaged parts should be replaced. The refueling tool can be refueled manually or with a grease gun.
In the process of use, strictly in accordance with the instructions, the equipment is broken midway, there are professional and technical personnel to repair, can not be on the side of the equipment modification.
Matters needing attention are detailed as follows:
1. In order to make the mill normal, the equipment "Equipment Maintenance and Safe Operation System" should be formulated to ensure the long-term safe operation of the mill. At the same time, necessary maintenance tools, grease and corresponding accessories should be available.
2, the mill in the process of use, there should be fixed personnel responsible for watching, the operator must have a certain level of technology.Before the installation of the mill operators must carry out the necessary technical training, so that they understand the principle of the mill performance, familiar with the operating procedures.
3. When the roller device is used for more than 500 hours or so to replace the roller, the rolling bearings in the roller sleeve shall be cleaned and the damaged parts shall be replaced in time. The refueling tools can be manually refueled with oil pumps and butter guns.
4. After the mill is used for a period of time, it should be overhauled and replaced with the wearing parts such as the grinding roller and the grinding ring and the spade-knife. The connecting bolts and nuts of the grinding roller device should be carefully checked before and after the use to see whether there is looseness and whether the lubricating oil is added adequately.
5, fineness adjustment, according to the size of the material, soft and hard, water content, specific gravity, processing of the fineness is also different, can adjust the mill side of the analyzer, high speed, high fineness, low speed, low fineness.Increase the fineness, the output will be reduced accordingly, if not up to the requirements should be adjusted fan speed, users can be flexible.
6. The scrap limit of the grinding ring of the grinding roller, the small wall thickness of the remaining grinding machine shall not be less than 10mm.
7, when parking, stop feeding first, the main engine still continues to say, so that the residual abrasive continues to grind, about one minute later, can close the main motor and analyzer motor, stop grinding work, then stop the fan motor, so as to blow the residual powder in the grinding machine.
