Pelletizing Operation of a Single Shaft Hammer Mill
When the rotor of the single-shaft hammer mill rotates at high speed, the hammer becomes radial (for the rotor of the suspended hammer) due to the centrifugal force. The rubber material enters the machine after being rolled by the feeding roller, and is immediately broken into particles by the impact and tearing action of the hammer. The rubber particles are discharged from the discharge screen hole at the bottom of the machine. block and leave it for the hammer to strike again until it passes through the sieve.

The single-shaft hammer mill does not rely on all the energy of the rotor parts to break the rubber, but mainly relies on the work done by the kinetic energy of the hammer to complete the crushing of the rubber.
The hammer mill should pay attention to the following matters when granulating:
(1) Before starting the single-shaft hammer mill, check whether there are tools, sundries, etc. on the machine, and open the valve to check whether the rotating parts and the discharge screen are damaged.
(2) Appropriate lubricating oil should be added to each lubricating part.
(3) All fastening parts of the single-axis hammer mill should be tightened.
(4) After the machine is turned on, run it for 2 minutes in an empty state, observe the machine, and if it runs normally, it can be fed and granulated.
(5) The speed at which the feeding roller bites into the rubber material must be synchronized with the feeding speed. If it is found that the feeding roller has broken pieces or accumulated films, it should stop immediately to adjust the roller distance of the feeding roller.
(6) During the granulation process of the single-shaft hammer mill, if it is found that the machine has abnormal noise or increased vibration, it should be stopped immediately for inspection.
(7) After the granulation operation is completed, the cleaning work must be done well.
