(4) How should the particle machine start up?

A: (1) Check whether the power supply is normally energized;

(2) Check whether the safety pin is broken;

(3) Check whether the travel switch is in place;

(4) Check whether the door of the pellet machine is closed properly.

(5) For the uneven surface of the particle material, how to improve the phenomenon?

A: 1, properly control the thickness of the powder feed, so that all raw materials can be fully softened when conditioning.

2, for more raw materials containing fiber, because it is easy to include steam bubbles, so do not add too much steam in this formula.

(6) What are the reasons why the particles produced by granulation are not tight enough and the powder is more? How to solve it?

A: Control the pelleting yield, improve the compression ratio of ring die, and adjust the formula when necessary.

(7) Causes and solutions for inconsistent color of granular material?

A. Control the amount of water added to the mixture and the degree of mixing uniformity. Control ring die quality such as hole finish, etc.; Control the fineness and uniformity of the material before granulation.

(8) What is the cause of bending and showing many cracks on one side of the particle material?

A: This phenomenon is usually generated when the particles leave the ring die, when the position of the cutter is far away from the surface of the ring die and the knife edge is blunt, the particles from the die hole extrusion is broken or torn by the cutter rather than cut off, at this time there are some particles bent to one side and the other side of the many cracks.

Improvement measures:

Increasing the compression force of the ring die on the feed means increasing the compression ratio of the ring die, thus increasing the density and hardness of the particles. Pulverize feed raw materials more finely. If molasses or fat is added, the distribution uniformity of molasses or fat should be improved and the amount of molasses or fat should be controlled to improve the compactness of particles and prevent soft feed; Adjust the distance of the cutting tool from the surface of the ring die or replace it with a sharper cutting blade; The use of bonding granulation additives to improve the internal binding force of particles.

(9) How to deal with the serious blockage of the die hole?

Answer: 1. After soaking in oil, slowly press in with compound feed and observe the discharge situation;

2. Feed whole corn or fractured corn slowly to observe the discharge situation;

3. Whole corn, oil and fine sand are mixed and fed to observe the discharge situation;

4, use electric drill to drill out the packing (improper operation, will damage the die hole).

(10) What happens when ring die drive rim needs to be replaced?

Answer: A: ring die centering pin or ring die locking bolt often break.

Two: the gap between the ring die and the transmission rim relative to the plane is very small or basic contact.

(11) What are the reasons for the quality problems of ring die?

A: There are generally the following reasons for the quality problems of the ring mold:

The fixing bolt is too short; Bolt quality problems and materials (8.8 grade); The fixing bolt is too long; Metal damage ring die; Fixing bolt hole contains dirt; Ring die drive rim or hoop wear; New and old ring die and press roller; Press roll regulation is too tight; Eccentric shaft adjustment direction is wrong; High opening rate or wrong pressure relief hole; Ring die mounting tilt; Drive rim or feed rotation cone wheel ring unclean; Excessive ring die wear; Continuous overload of ring die.

(12) What are the causes of ring die rupture?

1, the thickness of the ring die is too thin, the strength decreases; 2, the ring die is forced into the process of operation by hard objects (such as falling in the pelleting room bearing ball and other metal objects); 3, the gap adjustment of the roll die is too small; 4, the clamping surface of the ring die is seriously worn; the ring clamping is not tight or the ring falling will lead to flange damage
