How to Commission Pellet Feed Mill Unit
Commissioning pellet feed unit
1, we must first understand the pellet feed unit production line process and understand the
function of each specific process equipment;
2, should be checked one by one before commissioning the functioning of a particular device,
and understanding and granularity of particle machine used to match the die orifice mill, raw
material particle size should be fine, but not too small, preferably coarse, medium and fine fitness,
recommended ideal particle size distribution is as follows: A, 3.35mm particle size or more ≤1%
B, 2.0mm particle size above ≤5% C, 1.0mm particle size of more than about 20% D, 0.5mm
particle size of more than about 30% E, size not less than 0.25mm or less 20% F, about 0.25mm
particle size of about 24% above
3, before commissioning the first wash bin, remove the stones left behind during installation
and welding slag and other debris;
4, steam piping system before commissioning used to check whether a good decompression
functions and hydrophobic functionality required to ensure dry granulation quenched with
saturated steam, and to ensure there is always a 0.058-0.4MPA after valve steam;
5, adjust the distance between particles machine before starting the pressure roller and ring
mold, usually when the pressure roller rotating ring mold like turn non-transgenic (ie, pressure
roller and ring die optimum spacing of 0.1 ~ 0.4MM), do not make ring mold and pressure roller
spacing adjustment is too small, resulting in direct friction, so not only will speed up the ring mold
and press roller abrasion, and will reduce production time per unit of production.;

6, should not start when the volume of feed pelleting equipment instantly reaches the
maximum, you should add a little material side, while adding a little steam about 5-10 minutes, so
when the volume of feed to achieve the desired value (ie, the normal production of motor current
value 85 to 95% of the rated current value).
