In non-metallic mineral processing plants, by a number of machines and equipment is generally assembled and completed connection lines, and the installation and maintenance of machinery and equipment in the plant is an important part of the mechanical work.
The quality of installation and maintenance work has a great impact on production. If the quality does not meet the technical requirements, it will not only directly affect the normal production, but also cause premature damage of mechanical equipment.
In serious cases, mechanical or personal accidents may occur. Therefore, it is necessary to master the installation and maintenance knowledge of mechanical equipment, in accordance with its operating specifications.
Make mechanical equipment installation and daily maintenance and overhaul work to ensure the smooth operation of machinery and equipment.
For the installation of mineral processing machinery and equipment, the following points should be noted:
Machines and equipment must be installed on a solid foundation. If the foundation is not strong, it will affect the operation of the machine and equipment, and even affect the life of the machine or equipment.
The basic requirements for moving machinery (called machines) are more stringent. It is different from the basics of equipment (generally referred to as non-moving equipment), in addition to static load and dynamic load.
The dynamic load is due to the poor balance between the rotating part and the reciprocating part of the machine, and the greater the dynamic load, the greater the influence on the foundation. A machine that is not well balanced will quickly destroy the foundation (such as a ball mill is a poorly balanced machine).
Vibration is generated because the foundation is subjected to dynamic loads. In addition to damaging the machine, vibrations are often transmitted to adjacent equipment, machinery or houses through the foundation and cause cracks and premature damage. In addition, noise pollution caused by vibrations is also transmitted from a bad foundation.
Therefore, the foundation not only structurally meets the process requirements, but also absorbs vibration and noise of the machine. In addition, during the process, there should be no sinking, skewing, or overturning. It should also be able to transfer the load of the machine and equipment evenly to the soil foundation. After the completion of the construction, the basis of the machine and equipment operation is built on the soil. Therefore, before the construction of the large foundation, the drilling test of the foundation soil must be determined. The physical properties of the soil and the resistance to stress.
When designing the foundation, the pressure on the soil must not exceed the allowable pressure of the soil.
