What reasons cause that the grinding machine can not start?

There are many reasons for the fail start of grinding machines, the most common is that the motor power is not enough, and often need to start a few times so that it can be started after the formation of inertia. Because the start-up currend is very large, the unstable current burns out contactors, circuit, motor, and causing some impact to grinding machine, which shortens the useful life of grinding equipment.

Using slip speed regulating motor can solve the problem of the difficult start. But the low efficiency and motor maintenance increase the user's electricity costs. At present, a lot of flour machinery manufacturers are beginning to use switch reluctance speed regulating motor to replace the old motor, With characteristics of small startup current, big start torque and adjustable rotate speed, it solves the difficult problem of a difficult start of grinding equipments, meanwhile, the motor starting current is samll, no impact to the power grid, and extend the life of contactor parts.

Having solved the problem of difficult start, Let us talk about how to improve the processing efficiency of grinding machine. Appropriately increasing the number of operation can improve the effciency of grinding machine, but the number of operation can not be too high. Too high operation number will cause the problem, such as overheating, wear, and so on.

On one hand, due to the grinding machine uses the centrifugal force to processing, too high rotation number will increase the mechanical vibration and component wear efforts, which reduce the using life of grinding equipment. In addition, if the internal grinding effect has been destroyed, it will make the output ore become thick, processing materials can not reach qualified granularity, and increasing the wearing degree. Therefore, improving the operation number need to communicate with technicians and manufactures.

The quality of grinding machine are generally measured with the particle size of the passing rate.
