What are the advantages of using a motor soft starter for mixers?
In addition to being widely used in water pumps, air compressors and other loads, soft starters are also widely used in heavy-duty starting, such as ball mills, crushers, centrifuges, mixers, etc. Today, the soft starter manufacturer Akwell will learn with you what are the benefits of using a soft starter for mixers?


The purpose of a mixer is a machine with a bladed shaft that rotates in a circle or a trough to mix or knead substances to the desired consistency.


Mixers are classified according to the form of mixing, which can be divided into two types. One is a self-falling mixer, which puts the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum will mix the materials. The material is lifted to a certain height, and then falls freely by its own weight. Another kind of forced agitator, this one is that the stirring drum does not move, and the stirring is forced by the blades evenly placed on the rotating shaft in the drum.


If there are two kinds of installation methods, one is that the stationary mixer is installed on a pre-prepared foundation, and the whole machine cannot be moved. It is large in size and high in production efficiency. It is mostly used in mixing buildings or mixing stations. The other is that the mobile mixer itself has traveling wheels, and is small in size and light in weight, so it has good maneuverability. Applicable to small and medium-sized temporary projects.






For example, the mixer is basically a heavy-load start, especially if the stationary mixer is started directly, the starting current is too high (the no-load starting current can reach 4~7 times of the rated current, and the load starting will reach 8-10 times or more. ) has a great impact on the power grid, it is easy to cause the voltage of the power grid to drop, and it also affects the normal operation of other electrical equipment. Moreover, if it is started directly, it will also cause impact to the motor of the mixer, causing damage and reducing the service life.






After using the motor soft starter for the mixer, the modified motor and control system can reduce the starting current, reduce the wear of gear torque, and reduce the maintenance workload, which not only saves time, but also reduces belt wear and mechanical impact, saving maintenance. cost of.


In addition to improving the soft start and soft stop functions of the mixer, the soft starter also provides more perfect protection for the motor such as overload protection, overvoltage protection, undervoltage protection, overcurrent protection, and overtemperature protection.
