Effectively improve the ring die production, besides that the quality of ring die itself , the correct operation and maintenance can effectively improve the life of ring die. Please kindly read following, hope it can help you.

*Firstly, the regular maintenance of the pellet machine

1. Because the pellet machine is the host equipment of feed plant, the manufacturers should maintain regularly per day,per week,per month to ensure that pellet mill keeps a good and non-beating working condition, if the equipment has failure or some wearing parts wear, especially the driving wheel and the main shaft , should timely replacement of spare parts to ensure that ring die concentric circles 's normal use.

2. Install the iron removal device at the feeds inlet to prevent the metal etc. from falling into the pelleting chamber, resulting in severe cracking of the ring mold.

3. When assembling the ring die, should check the abrasion condition for drive key, hoop, wear-resistant lining rings of driving wheel, wear-resistant lining of roller shaft, adjust wheel and feed scraper, cutter and other spare parts, the replacement should be prompt to ensure the normal operation of the pellet machine. If the hoop can not tight ring die,it will have the vibration, which seriously affect the ring die's life, and even cracking, should be replaced in time, the feed scraper's abrasion will decline the capacity of pellet mill.

*Secondly, the repair for ring die work

1. Due to the different varieties of feeds, it involves the difference for ring die material, opening rate, inner cone hole, effective length and etc.. Finding a advanced professional and technical manufacturer to customize different ring die, combined with raw materials and actual use, so as to ensure that the ring die use greatly and well.

2. Using new ring die,had better use rollers together.

3. The gap between the roller and the ring die must be controlled between 0.1-0.3mm, do not let the eccentric roller contact the ring die's surface or the gap of a side is too big, so as not to resulting in the abrasion of ring die and rollers or no feed pellets out.

4. When starting pellet mill, the speed for feeding volume must be from low to high, do not start at high-speed,it may result in the damage of ring die and pellet machine due to sudden overload or blocking material.

*Thirdly, the regular maintenance for ring dies

1. After the ring die uses for some time, when not use, should use non-corrosive oil materials to squeeze out the original feed , otherwise, the heat make feeds( which stays in the holes) dry and harden, resulting in the following:

(1)at the beginning of production, the ring die blocked,cannot make out the feed;

(2) the ring die to bear high stress and weaken its hardness, may produce ring mold cracking;

(3) parts of the mold hole blocked, reducing the production capacity and efficiency.

2. After using for a period of time, should check whether the ring mold inside has the bulge, if yes, using grinding machine to grind the bulge part to ensure the ring die's production and service life.

3. If the block of ring die leads to no feeds out , can oiling soak or cook firstly, if still not pelletize, using electrical drill to drill blocked materials, then use the oily materials with fine sand grinding and polishing.

4. When assembling and disassembling ring mold, can not use hammer and other hard steel tools to beat ring mold's surface.

5. Record ring die usage per shift, in order to accurately calculate the actual life of the ring die.

6. Ring die should be stored in a dry and clean place, if stored in a wet place, it will have hole corrosion, and reduce the lifetime or not pellets out.
