Particle machines sometimes show the problem of no output or difficult feeding and low yields, leaving many inexperienced users unsure of how to deal with these situations. Large aspects, first, the machine itself does not regulate the good, and second, the raw material to suppress the particle is not good.Machine itself, on the one hand, is mainly in this part of the mold and the pressure roller.
Cause particle machine difficult to discharge the reasons for the low yield:
1, if you are using a new ring die, first check whether the ring die compression ratio and processing of raw materials match, the ring mold compression ratio is too large, powder resistance through the die hole, the particles out too hard, the output is low ; The ring mold compression ratio is too small, the particles out of the pressure does not form, you must re-select the ring mold compression ratio and then check the ring mold hole smoothness and ring mold is out of round, inferior ring mold because the ring hole rough, Circularity leads to large discharge resistance, particles are not smooth, and the discharge of difficult, lower yield, it must use high-quality ring die.
2. If the ring mold for a period of time, you must check the ring mold wall taper hole is worn, the pressure roller is worn, such as severe wear and tear can ring mold repair, re-countersunk tapered bore, pressure roller wear must be replaced, ring Taper hole wear on the yield has a great impact.
3, the ring die and roller gap to be adjusted correctly, the production of livestock and poultry feed when the general spacing of about 0.5mm is appropriate, the spacing is too small will make the pressure roller friction ring mold to shorten the ring mold life, spacing is too large will cause pressure roller skid , To reduce production.
4, pay attention to the time and quality of the raw material quenching, in particular, to control the water into the machine before entering the raw material before quenching the water is generally 13%, such as high water content, raw material after quenching the water is too high (moisture ≥ 20%), there will be the phenomenon of mold slippage, not easy to material.
5, to check the distribution of raw materials in the ring die, raw materials can not run unilateral, such as a similar situation, we must adjust the size of feeding scraper position, so that the raw material distribution in the ring die, so that can extend the use of ring mode Life expectancy, but also more smooth discharge.
As the moisture content of this material should be well controlled, because the moisture content of the assembly will directly affect the molding machine of the molding rate and yield, so this can be used in the raw materials into the machine to measure the humidity test equipment to check the humidity Is not in a reasonable range of granulation.To make the machine efficient and productive work must be debugged every aspect of the work well.
