How to solve the problem of double-shaft shredder when the motor heats up

The market demand for double-shaft shredders in the waste material processing industry is gradually increasing, and it has been recognized by more and more customers. Double-shaft shredder machine is suitable for the processing of various materials, such as metal, plastic, rubber, wood etc. Because the working intensity of the double-shaft shredder is very strong, if the supporting motor runs for a long time, the motor will heat up or lack oil. So how should we solve it when the double shaft shredder fails?
1. The main power of the double-shaft shredder machine comes from the motor, which is the main configuration of the machine, so we must pay attention to the selection of the motor. Generally, the motor is fully equipped when the shredder machine leaves the factory, but some Customers want to buy on their own. The advantages of self-purchasing need to be known. If you do not know the motor or the brand of the cheap motor is not guaranteed, the motor will easily heat up and break down. Therefore, to solve the problem of motor heating from the source is to buy a brand-name motor. , can reduce the failure rate of the motor.
2. There are other reasons for the motor to heat up due to the large load and high current. After using the motor for a period of time, check the motor, such as whether the motor fan is damaged, whether the motor bearing is damaged, whether the motor environment is sealed and heat-dissipated, and the ambient temperature is high. You can Measure the motor current to see if it exceeds the rated current, and then check the motor fan and the environment.
3. Regarding the adjustment of the tension of the V-belt of the shredder, when the V-belt is too tight, the motor bearing is prone to heat; when it is too loose, the speed decreases, and the V-belt is easy to slide. When adjusting the tension of the V-belt, loosen the bolts that fix the motor seat, and use the adjustment bolts to change the position of the motor on the slideway, so that the V-belt reaches a suitable tightness, and then tighten the fixing bolts.
4. Make the spindle and tool center concentric, and adjust it in time if there is a deviation. Assuming that the shredder tool is prone to broken knives and waste, it is usually caused by the inconsistency between the rotation base of the main shaft of the shredder and the base of the tool during processing. To adjust in time, please refer to the article on how to calibrate the main shaft of the shredder. The motor’s power cord must not be too long or looped. This will easily cause the motor to undervoltage or undercurrent. The rated current of the wire should be greater than the rated current of the motor, otherwise the motor will easily heat up under the condition of undervoltage or current.
