There is a certain relationship between the rotation speed of the drum screens ( trommel screens ) and the output of the sieve material and the diameter and length of the drum. Generally, the smaller the particle size of the sieved material, the larger the rotation speed required, and the large rotation speed can generate centrifugal force to facilitate the screening of the material and increase the output. The second is the diameter and length of the drum. The larger the diameter and the longer the speed of the rolling mill, the lower the speed. The low speed is conducive to the smoothness of the machine, and the higher the safety factor, the longer the life of the drum screen.

Therefore, how many turns of the trommel screen every 1 minute is not fixed, and the size of the drum screen should be determined according to the actual situation to adjust the speed. Such as:
The rotation speed of the 1030 type drum screen is about 25 revolutions per minute;
The rotation speed of the 1545 type drum screen is about 18 revolutions per minute;
The 1860 type trommel screen has a rotation speed of about 14 revolutions per minute.
