1, water is not added, the better?
Is not. How much plus is based on the moisture content of the feedstock may be, not random, we must add the technical guidance of the Ministry.
2, how high vapor pressure as well?
0.25-0.30MPa but before the steam pressure reducing valve generally not be lower than 0.6MPa, because the need for saturated steam pelleting quenched. Pressure after decompression depends on the recipe, rather than arbitrarily making.
3, the steam condensate system can not drain it?
Be sure to drain, especially when just machines, or vulnerable to jam.
4, Why do you want to change the amount of steam according to the recipe?
Different formulations have different characteristics, by adding the same amount of steam pressure and temperature will cause unnecessary trouble, such as loss of nutrients, grain quality can not be guaranteed, serious blocking will die, and low productivity.
5, open security machine (always much lower than the rated current), okay?
Wrong, generally 90-95% of rated load should be maintained, otherwise die, the pressure roll wear large, high power consumption, low yield, grain quality can not be guaranteed.
6, finished pellet moisture content as low as possible?
Wrong. General region to maintain 12-13% moisture particles finished more reasonable, both conducive to preservation, without affecting the product out rate; while not affecting animal feed.
7, multi-grade flour sieve back, why?
Mainly due to the quenching effect is poor, recipes or ring die as a result of particle hardness is not enough reason, chalking serious.
8, on the die roll gap
Reasonable die roll gap on production efficiency, particle hardness, wear ring mold and the pressure roller has a direct impact. Tight, yield, grain loose, easy blocking machine, faster wear; too loose, small production, hard particles, easily blocking machine; die roll gap with no load (no residual material suppression chamber), the pressure roll like turn non-genetically appropriate (with a slight metallic percussion).
9 reasons for the breakdown ring mold
a, ring mold material reasons, the opening rate is too high, not enough to cause strong enough thickness; b, excessive wear; c, suppression chamber into instant impact caused by foreign bodies excessive force.
10 reasons to install ring mold taper off bolts with frequent
a, the position of the wear ring mounting surface wear caused by friction of the contact is not enough to withstand the shear force of the bolt;
b, new cone ring mold and machine wear rings caused by the friction surface is not consistent enough to withstand the shear force of the bolt;
c, new share bolt strength is not enough.
