The ball mill special type inverter is a special type inverter for all kinds of ball mills. For a long time, the wall, land, bricks, and chemical plants generally use ball mill grinding ceramic materials. It generally uses simple power frequency control, which is easy to cause excessive grinding of materials. The desired grinding cycle is longer, low grinding efficiency, unit product work The large load start current at the time of motor power frequency starts great impact on the equipment and grids.
The production and maintenance of the mechanical energy-saving ball mill is also large, and the loss of electricity is quite amazing, which will inevitably bring the manufacturer It comes to many unnecessary troubles and severe resources, so with the development of the social economy and the expansion of the company's production scale, the disadvantage of direct industrial control ball mill has exposed, and the rapid development of various industrial enterprises has been severe.
Now the cement ball mill used, regardless of raw material grinding or cement grinding, one is divided into two to three warehouses, a warehouse is a coarse grunge, the main function is Broken large diameter particulate material. Second, the three warehouse is a fine grinding position, and the main function is to grind the crushed material that is crushed into the fineness from a warehouse to the second and three wares. A silo of a ball mill has two shortcomings in the internal structure, affecting the production and crushing and grinding efficiency of the energy-saving ball mill.
In order to reduce the material fineness of the thick mill to the fine grinding bin, it is necessary to ensure the efficiency of the coarse mill, does not affect the grinding machine, and our structure The form has been improved, which guarantees that only lt; 3mm fine powder can enter the two warehouse, and the coarse granules return to a warehouse to continue grinding, but also guarantees the smooth discharge, does not affect the efficiency of a warehouse, thus achieving The purpose of increasing the stage and reduces power consumption.
1. When the motor is overhaul, the motor stator temperature instruction instrument is added and the meter is connected to the operating position so that the operating work is monitored.2, the grinding volume is too large, and should be reduced.
3, the carbon brush of the motor or the heating or heat dissipation is poor, and the cooling fan is dissipated.4, motor insulation or improper installation, should be processed for a long time after the ball mill is stopped.
5, inspection work equipped with clamp current table, point temperature meter and other detection instruments to check, record, information on the operation, maintenance and fault analysis of the equipment.
