The smashing method of the shredder is through a high-speed rotating angular blade in a closed crushing tank directly driven by the motor shaft of the lower part of the shredder. After the material comes into contact with the high-speed rotating shredder blade, it is impacted and shattered. The purpose of the machine. Generally speaking, after the crusher has been used for a period of time, the seal of the upper bearing part of the crusher will slowly create a gap as it is used. Very fine dust invades into the motor bearing, causing the noise and vibration of the crusher to increase, and the temperature is within a short period of time. Rise rapidly.

In practical applications, because the pulverizer uses an ultra-high-speed DC motor, the heat generation is also high. The main heating parts are the carbon brushes and the commutator and the tank. The carbon brushes are in contact with the motor during the energized operation. On the surface of the device, the external power supply (usually a DC excitation current) of the motor is provided to the winding (field winding) of the rotor through a slip ring (on the rotor, running with the rotor). It plays the role of current commutation, In this way, when the rotor rotates, the DC current flowing in is kept flowing in from one end of the rotor, so that the motor rotates in one direction. The carbon brushes are in good contact with the rotor of the motor, and the carbon brushes are connected to the power supply to provide electrical energy for the rotor. Because the carbon brush is in frictional contact with the commutator for a long time, wear occurs. When the length of the carbon brush reaches the level that needs to be replaced, the support spring behind the carbon brush will no longer work, which may cause contact between the carbon brush and the commutator If the pulverizer is energized and does not start, it can be solved by replacing the carbon brush with a new one and cleaning the rotor head with alcohol.

In actual application, the button switch of 　　 shredder will also cause the internal power contacts of the switch to be ablated due to frequent stops. When one of the internal contacts of the power switch is in poor contact, press the switch box again The shredder will not start again after the button is pressed, these problems can only be solved by replacing the switch box.

There are two ways to connect the power cord of the grinder. One is that there is a 3-pin power cord jack on the power box of the grinder. We only need to insert the dedicated power cord provided in the grinder accessories into this jack. Yes; another connection method is to directly introduce the power cord into the power box of the shredder, so that you don't always have to worry about the loosening of one end of the power cord. A commonly used small-scale grinder has always been known for its convenient use and reliable quality.
