Improvement of Ball Grinding Mill components

When the Ball Grinding Mill is used, it often causes frequent shutdown and maintenance of the equipment due to component factors, which seriously affects the normal operation of the equipment. Therefore, after continuous research and analysis, the technician analyzes the equipment. The following is an introduction to the improvement of the components of the Ball Grinding Mill.

High pressure oil pump improvement

Ball Grinding Mills generally use static pressure and dynamic pressure lubrication. At this time, the lubricating oil relies on the rotation of the Ball Grinding Mill to form “dynamic pressure lubrication”. Since the high pressure oil pump is intermittently working, there is always lubricating oil in the pipeline between the oil pump outlet and the bearing bush. When the temperature is low, the viscosity of the oil will be very large, and the resistance will be larger, causing the pressure of the high-pressure oil pump to be too high when starting, often overloading, and the overflow valve frequently causes malfunction. It is recommended to use the 2.5MZB high pressure oil pump to increase the rated working pressure of the high pressure oil pump from 31.5MPa to 40MPa. The electric heating cable is wound around the oil pump outlet to the bushing pipe. Even in winter, the pipe temperature can reach 30 °C, which greatly reduces the viscosity of the oil. After the transformation, the high pressure oil pump rarely malfunctions.

Bearing improvement

Since sliding bearings are used in Ball Grinding Mill equipment applications, their energy consumption is high and maintenance is not easy. It is recommended to replace the plain bearing with a rolling bearing while eliminating the lubrication station. The rolling bearing adopts double-layer labyrinth sealing structure, filled with special flexible sealing grease, and the sealing effect is good, which ensures the internal cleaning of the bearing. And the use of rolling bearings without parking maintenance, bearing replacement of 90 degrees a year or so, extending bearing life. In addition, after the improvement, it is only necessary to regularly lubricate the lithium base grease, and the energy consumption and spare parts consumption are effectively controlled to ensure the smooth production of the Ball Grinding Mill.

Heat exchanger improvement

The heat exchanger is an important facility to ensure the safe operation of the Ball Grinding Mill during the summer. The original heat exchangers are tubular heat exchangers. This type of heat exchanger is bulky, inefficient, and difficult to clean. It is more difficult to repair water leaks. It is recommended to replace the original tubular heat exchanger with a plate heat exchanger, which overcomes the shortcomings of the tubular heat exchanger. According to the actual operating conditions, the heat exchange area is appropriately increased in some places. For example, the heat exchanger area of ​​the grinding tail thin oil station is increased by 2m2 compared with the grinding head thin oil station, because the grinding tail thin oil station needs to take away the heat generated by the bearing friction, and also takes the material in the Ball Grinding Mill to conduct through the hollow shaft. Part of the heat.

Four Steps Ensuring Safety And Efficiency Of Machine Preparation And Shipment

  • 1. Checking order. With the sales contract, the order tracking clerk checks the models and quantities of machine and spare parts for machine preparation.
  • 2.Quality test before delivery. Upon completion of the manufacturing of equipment, the quality inspector strictly checks quality of every machine with the checklist.
  • 3. Check items when packing. Before packaging and shipment, the order tracking clerk checks the packaged items again with the packing list to avoid loss of items.
  • 4. Packaging and transport. Professional packaging and modular solution of transportation guarantee the safe and smooth delivery.
