The reducer uses large and small gears to reduce the output speed of the motor and increase the output torque of the motor. It is very important in the tearing process. Therefore, a good reducer can prolong the service life of the single shaft shredder The single shaft shredder is only equipped with a moving shaft, and the blades are installed on this shaft to form a form of mutual shear with the fixed knife on the box.


   
3. Performance characteristics of double shaft shredder:

The materials vertically fall into the high-speed rotating impeller from the upper part of the machine. Under the action of high-speed centrifugal

force, they are separated with another part in the form of umbrella. The materials around the impeller produce high-speed impact and crushing.

After the materials collide with each other, they will form eddy currents between the impeller and the casing, collide and rub with each other for

many times, and discharge directly from the lower part, Form a closed circuit for multiple cycles, and the screening equipment controls to

achieve the required particle size of finished products.


4. Equipment operation:
 5.1 preparation:
before starting the machine, first check whether there are materials, sundries and jamming in the crushing chamber; before

starting the machine every day, check whether all fasteners are completely fastened, and deal with them immediately if they are loose; check

the lubrication of each rotating part before starting the machine 5.2 start up: 
the machine and transmission parts can be started up only after the inspection proves that they are in normal condition; the

machine must only be started under no load, otherwise it is easy to damage the motor, reducer, coupling, etc; start (jog the test run first) if

there is any abnormal condition or abnormal sound, stop the start immediately, find out the cause and eliminate the fault before starting again5.3machine operation:
When the machine is running, the maintenance personnel should often go to the side of the machine to observe the operation: whether the

machine has abnormal sound. If it occurs, first determine the position, and then stop the machine for inspection and treatment; whether the

temperature rise of the motor is too high. Under normal conditions, the maximum temperature shall not exceed 80 ºC; check whether the bolts

at the rotating part are loose. If they are loose, stop the machine immediately.5.4shut dowu:
Before the machine stops working normally, the feeding shall be stopped first, and the crusher can be stopped only after all materials in the

standby are broken. In case of machine failure or dangerous situation, the power supply can be cut off immediately.
