Ball mill power saving principle

Wet ball mill (ceramic enterprises) is selected and configured according to the diameter of the drum and the process requirements and production volume It contains motor (primary power) reducer, hydraulic coupling, auxiliary motor, brake coil, pulley, drum, etc..

The original control for running at a constant speed, only through experience and test to determine what products need to do how much time, that is, when the ball, while the starting force distance is very large and difficult to start. And after a large number of trials and data summary of our company, for the ball mill developed ACI ball mill economizer, production of various power section of the series of products DLT-QM11 control cabinet and Q11 controller.

Working process: The ball mill is based on media movement, and the grinding process of material particles occurs between media and media and between media and liner plate. The media movement is divided into throwing down (adapted to coarse grinding), lagging (adapted to fine grinding) and centrifugal (lost grinding effect).

According to the above three types of motion and force, in order to improve the efficiency of ball mill, the ball mill economizer adopts vector control calculation to decompose the force longitudinally and laterally, make it a scalar quantity in the rotating axis and control it, and at the same time use fuzzy theory to track and sample the ball mill, so as to adjust the output torque and speed. It makes it achieve the best grinding effect with the most economical power. The following figure shows.

Save electricity through four areas

1. The soft start function of the economizer can reduce the starting current by 4-7 times.
   
2. The power factor of the economizer can reach above 0.99, while the power factor of the original motor is below 0.88.
   
3. Because different products require different speeds, and because power is proportional to the square of speed, we can set different control speeds at different times, and customers are free to set or choose (through a microcomputer processor to achieve).
   
4. The economizer can automatically track the best running current of the motor in real time, so as to adjust the corresponding output voltage and torque to reach the best economic running point.
   

According to the above four points, the comprehensive power saving effect can reach more than 10%-35%, the average can reach about 15%, the effect is very significant.

It is different from the general frequency converter, soft starter and power factor compensator, it is an organic combination of the three, a perfect combination of overcoming starting difficulties and effective energy saving, and is the preferred energy-saving product for modern ceramic enterprises.

Functions and features of ball mill economizer

1. ACI ball mill special power saver has unique dynamic power saving function, and the power saving rate reaches 10%~35%.
   
2. After the installation of ACI ball mill special economizer, the ball mill start becomes real soft start, the starting impact force of the ball mill is greatly reduced, and the life of the belt and gear of the ball mill is greatly improved.
   
3. After using this machine, since both the starting impact current and working current of ball mill are reduced, it will not cause the fluctuation of grid voltage and decrease of grid voltage, which eliminates the fault phenomenon such as tripping of other electric equipment caused by this.
   
4. ACI ball mill special power saver has perfect protection functions of overload, overcurrent, short circuit and grounding.
   
5. It is easy to set the ball mill time and automatic stop time, and it is also easy to choose the grinding time.
   
6. Low investment and high return, all investment can be recovered within 5-12 months by saving electricity cost.
   

Our ACI ball mill special economizer is a special ball mill special economizer developed and produced on the basis of frequency conversion with special improvement and software enhancement, which is different from the general inverter. After the installation of ACI ball mill special economizer in ceramic factory, the ball mill can start easily and the starting current can be controlled below the rated current (for example: 100 tons ball does not exceed 500A, 60 tons ball does not exceed 400A, 40 tons ball mill starting current does not exceed 300A), so the starting performance of the equipment is very good, which greatly reduces the starting current of ball mill, the impact of power grid and mechanical equipment. It also improves the efficiency of transformer capacity use by more than 20%, in the same transformer capacity, it can increase the number of ball mills and increase the equipment without increasing the transformer capacity, saving a lot of money, in addition, it can also improve the ball mill belt, bearing, gear life of the reducer, etc., reducing the cost of maintenance.

When starting, it will not cause fluctuation of power grid and decrease of power grid voltage, which eliminates the tripping of other power equipment and undervoltage fault caused by it. It is especially suitable for the use of generators and ball mills in low power grid.

The need for energy-saving renovation of ball mill

Factories that use ball mill equipment generally have long working hours and consume a lot of electricity, with annual electricity expenses reaching millions, causing a heavy cost burden to the factory. The electricity consumption of ball mill accounts for 40-60% of the total electricity consumption of the workshop, therefore, in order to effectively bring down the cost expenditure, we must first solve the problem of electricity consumption of ball mill.

And the existing ball mill equipment and its working method mainly have the following problems：

1. The existing starting and control methods of ball mills are not power-saving, such as through the transformation can save a lot of electricity costs.
   
2. The impact force of the ball mill is not large when starting with the existing starting method, which will easily cause damage to the ball mill bearings and gears of the wave box and result in large maintenance costs.
   
3. When starting the ball mill with the existing starting method, the impact current is very large (usually 7-8 times of the rated current), which will cause voltage fluctuations in the power grid and reduce the power grid voltage, thus causing other power equipment to trip and malfunction, which will inevitably affect normal production.
   

Therefore, it is extremely necessary to carry out power saving transformation for ball mill equipment. After the transformation, not only can significantly reduce the cost of electricity, maintenance costs, reduce costs, and by reducing the line loss and line heating, can extend the service life of the ball mill, reduce noise pollution, while improving the safety factor of the workshop production line.
