Method for troubleshooting common faults in the operation of feed granulator

1. Analysis of the difficulty in discharging the granulator and the low yield. L44 China Feed Industry Information Network - Based on feed, serving animal husbandry

1 If a new ring mold is used, first check whether the compression ratio of the ring mold matches the raw material produced, the compression ratio of the ring mold is too large, the pressure of the particles is too hard, and the output is low, and the compression ratio of the ring mold must be changed again; L44 China Feed Industry Information Network - based on feed, serving animal husbandry

2 Check the smoothness of the inner hole of the ring mold and whether the ring mold is out of round. Some inferior ring molds will have rough inner holes, the ring mold will be out of round, resulting in unsmooth discharge, uneven particles, difficulty in discharging, and low output. Must use high-quality ring mold; L44 China Feed Industry Information Network - based on feed, serving animal husbandry

3 If the ring mold is used for a period of time, it is necessary to check whether the inner hole of the ring mold is worn or not, and whether the pressure roller is worn. For example, if the ring mold is worn, the ring mold can be reworked and repaired, the pressure roller wear must be replaced, and the ring mold is worn. Production has a great impact; L44 China Feed Industry Information Network - based on feed, serving animal husbandry

4 ring mold and pressure roller gap need to be adjusted correctly, the spacing is too small, the pressure roller will increase the friction ring mold, will shorten the use time of the ring mold, too much spacing will cause the pressure roller to slip and discharge is not smooth, so that the output is reduced; L44 China feed industry information Net - based on feed, serving livestock

5 pay attention to the time and quality of raw materials quenching and tempering, especially to control the moisture of the raw materials before entering the machine. The moisture content of the raw materials before the quenching and tempering is generally 12%-13%, and the moisture after quenching and tempering is maintained at about 14%. The quality of the temperature will be affected, the effect of quenching and tempering is poor, and the mold will be blocked and slipped after the raw material enters the ring mold.

6 to check the distribution of materials in the ring mold, can not let the material run unilaterally, if a similar situation occurs, the position of the feeding scraper must be adjusted to make the material evenly distributed in the ring mold, which can prolong the service life of the ring mold. At the same time, the discharge is smooth. L44 China Feed Industry Information Network - based on feed, serving animal husbandry

7 The granulator runs “with disease”, and the bearing runs outside the circle, which will cause the granulator to work weakly and the current is unstable, which will reduce the output. L44 China Feed Industry Information Network - based on feed, serving animal husbandry
