How can suspension magnetic separator improve power consumption
Suspension magnetic separator manufacturers: In the production line of cement and other powder materials, in order to prevent metal debris from entering the vertical mill and causing equipment vibration, usually iron removal equipment is installed above the feeding belt into the vertical mill, such as the suspended type Magnetic separator is one of the more commonly used models.
The traditional suspension magnetic separator is manually controlled on site. Before the mill is started, the iron separator needs to be turned on on site. After the vertical mill is running, the DC excitation circuit of the suspension magnetic separator has been connected to remove iron, and the self-unloading belt can continuously rotate to complete the iron removal. The driving power of the self-unloading belt is generally 6kW. According to the power factor of 0.8, the daily power consumption is almost 115.2kWh. In the process of iron removal, we found that when there is no metal adsorbed on the iron remover, the self-unloading belt will still keep running, resulting in a certain amount of waste of electrical energy.
In view of the above situation, we have made corresponding improvements to the electrical control system of the suspension magnetic separator. It is controlled by the PLC module instead, and the time for the start and rotation of the self-unloading belt is set by the central control computer. After the vertical mill is running, the DC excitation circuit of the suspension magnetic separator has been connected to the iron removal, and the self-unloading belt runs every 11 minutes for 1 minute to complete the iron removal. After the improvement, the self-unloading belt will run for 2 hours a day, or calculated according to the power factor of 0.8, and the daily power consumption will be reduced to 9.6kWh. After the improvement, the actual production effect verification can not only meet the production needs, ensure that metal foreign bodies will not enter the grinding, but also reduce the consumption of electrical energy and save electricity costs. At the same time, due to the short operating time of the equipment, the maintenance cost is also reduced accordingly, and the use efficiency is very ideal.
