Incorrect use and operation method is easy to cause particle machine ring mold cracking, affecting the normal production, let's analyze the particle machine ring mold cracking reasons and solutions.

(1) when the hoops working face youdao has wear marks towards the bright point and the driving wheel working face, the hoops' internal clamps have been worn or deformed, resulting in ring mold cracking.

Solution: the hoop must be replaced in time.

(2) ring mold cracking is caused by wear and tear of mating surface of transmission wheel and obvious loosening of mating surface of mold and roller.

Solution: must promptly replace the transmission wheel or repair, or increase the ring die assembly surface with dimensional tolerance.

(3) ring mold cracking is caused by wear and tear or deformation of die liner.

Solution: must promptly check and replace the die liner.

(4) due to the wear of the transmission key, the ring die impinge on the open assembly.Catch with the transmission wheel loose is also related to the regular measurement of key and keyway clearance, timely replacement of the transmission key.

(5) ring mold cracking is caused by spindle vibration due to spindle bearing damage.

Solution: timely replacement of spindle bearing.

(6) the butterfly spring is less elastic than the hub, which makes the spindle sway and causes ring mold cracking.

Solution: add or replace butterfly springs.

(7) ring mold cracking is caused by excessive load caused by improper safety pin and safety pin seat.

Solution: qualified safety pins must be used.

(8) similar to the effect of the iron removal device changes so that the ring molder surface indentation of metal objects, resulting in ring mold cracking.

Solution: must promptly check and clean iron removal equipment.

(9) as the pressure roller is not installed in place, the relative deviation between the pressure roller and the axial working area of the ring mold results in cracking of the ring mold.

Solution: install the roller assembly correctly.

(10) ring mold cracking is caused by hard contact between ring mold and pressure roller due to too small clearance between ring mold and pressure roller.

Solution: reasonable hearing gap between 0.1mm and 0.3mm, and the new mold with a new roller.

(11) ring mold cracking is caused by the increase of fiber material and the failure of feeding scraper to feed.

Solution: install a new scraper.

(12) when the ring mold is stopped for a period of time is not used, there is no "washing mold", the particles in the ring mold hole become hard, the next discharge is difficult, extrusion pressure is too high and the ring mold cracking.

Solution: non-corrosive oil must be filled immediately.

(13) cracking of ring mold is caused by direct hammering of ring mold by hard steel tools (such as hammer) for loading and unloading ring mold.Use a wooden hammer if ring molds must be installed with force.

(14) adjust the feeder in time when the feeding amount is too large or the ring mold with small aperture is replaced, and the pelleting is considered as unbalanced production, resulting in the increase of ring mold load and cracking of ring mold.

Solution: adjust feeding motor speed, adjust chin controller or electromagnetic controller.

(15) the hole wear of the die cover becomes larger and the end face is deformed. The screw bolt is loose, which causes the screw hole on the end face of the ring die to tear.

Solution: replace the pressure mold cover.

Equipment also has life and soul, only love plus, normal operation can extend its life, improve the quality of particles.
