Find the method of adjusting the ring die of the granulator, the more detailed the better, thank you

After the ring die granulator is installed, some parts should be adjusted. These adjustments include the following.

1) Adjustment of roll and ring die clearance It is very important to correctly adjust the roll and ring die clearance. A gap that is too small can lead to severe wear of the roll ring die; If the gap is too large, it will affect the granulation effect and yield. The general clearance is millimeters.

Open the door cover of the granulator, remove the ring die cover, and remove the material accumulation in the machine, and then adjust the gap between the roll and the ring die by twisting the relevant nuts and adjusting screws.

2) Adjustment of the position of the cutter Adjusting the position of the cutter can obtain pellets of different lengths. Generally, the length of pellet feed is a multiple of the diameter of the pellet. When adjusting, the lock nut should be loosened first, and the adjusting handwheel should be rotated to make it forward or backward, and the distance from the cutter to the ring die should be changed.

3) Adjustment of feeder speed Changing the speed of the feeder can change the material conveying capacity of the feeder. Different speeds can be obtained by adjusting the speed control button on the controller controller. When adjusting the speed of the feeder, the amount of steam added should be adjusted accordingly to ensure that the material has the appropriate temperature and humidity and ensure the quenching and tempering effect.

4) Adjustment of the angle of the agitator paddle The installation angle of the agitator paddle affects the filling coefficient of the material in the agitator, the propulsion speed and the length of the material quenching and tempering time. If the installation angle is too large, the filling coefficient is reduced, the material is fast, and the quenching and tempering time is short, which affects the quenching and tempering effect; On the contrary, the installation angle is too small, and the material is advanced slowly, which is easy to cause blockage. In general, a suitable filling factor is a corresponding blade angle of 80°.

5) Adjustment of steam addition The amount of steam added has a great impact on the quenching and tempering effect and granulation effect. When adjusting, the amount of steam added is determined according to the water content of the powder and the water content of the quenched and tempered powder to be obtained, and the actual quality of the steam is considered.

Netizen, I have also consulted relevant feed machinery manufacturers before, and one of them, Yongli Machinery, has explained that quenching and tempering.

The device is mainly used to improve the quality of feed pellets, and the detailed role is as follows:

1.It is conducive to feed pelleting and molding, making the feed easy to pellet and forming, and reducing the pulverization rate of pelleting.

2.Improving the digestion and absorption rate of feed? , so that the digestion and absorption rate of protein and starch and other components can be increased by 10% 12%.

3.Increasing the stability of aquatic pellet feed in water? , improve the gelatinization degree of starch, so that the stability of pellet feed in water can reach 30min, the most 4

Up to 3 6 hours, its stability mainly depends on the formula and conditioning performance. Of course, the granulation process also helps to improve the stability in the water.

5.Increase the output of the pellet mill and reduce the power consumption? , increase the output of the granulator by 25% to more than 50%.

6.Reduced wear and tear on dies and rollers? , the life of the die and roller is extended by 30% to 50%.

7.Destroy and kill harmful factors up to 20% and 60% or more.

Summary. Hello dear! Glad to answer for you: Granulator roller ring die gap adjustment A: Hello kiss<>

The direction of rotation of the ring die is generally clockwise. For the granulator equipped with two pressure rollers, the maximum eccentric convex edge of the left pressure roller should be installed in the upper left half of the ring die, and the maximum eccentric convex edge of the right pressure roller should be installed in the lower right half of the ring die. Under normal circumstances, the gap between the pressure roller and the ring die should be adjusted to about 400um.

When adjusting, the outer surface of the pressure roller should be slightly in contact with the inner surface of the rotating ring die, and under the drive of the ring die, it should be like turning but not rotating, and the gap between the two with small die holes should be smaller, and the gap between the two with large die holes should be larger; The gap between the new rollers should be smaller, and the gaps between the old rollers should be larger. If the gap between the pressure roller and the ring die is too small, the pressure roll and the ring die are easy to wear, which shortens the service life of the pressure roll and the ring die. And it's noisy; On the contrary, the gap is too large, which is easy to cause discharging difficulties.

Summary. How to solve the problem of different particle sizes produced by the feed pellet machine, the feed particles of different lengths affect the overall appearance of the feed, and will also lead to the feed can not be fully utilized by the animal, resulting in the waste of the feed pellet machine The particle size of the production is not the cause. At the same time, the material distribution in the granulation room is uneven; The feeding amount of the granulator is uneven, and the quenching and tempering effect fluctuates greatly; Inconsistent die roll clearance; Inconsistent wear of the pressure rollers; The amount of wear of the ring die guide port, inconsistent along the axial direction or more holes blocked on the ring die; Along the axial direction of the ring die, the discharging speed at both ends is less than the speed in the middle.

When designing the ring die, the decompression hole is too large compared with the effective hole, and some particles are broken in the decompression hole; Ring memes with small particle size are especially prone to uneven particle length due to the length of the decompression pore. The position or angle of the cutter is unreasonable.

At the same time, the material distribution in the granulation room is uneven; The feeding amount of the granulator is uneven, and the quenching and tempering effect fluctuates greatly; Inconsistent die roll clearance; Inconsistent wear of the pressure rollers; The amount of wear of the ring die guide port, inconsistent along the axial direction or more holes blocked on the ring die; Along the axial direction of the ring die, the discharging speed at both ends is less than the speed in the middle. When designing the ring die, the decompression hole is too large compared with the effective hole, and some particles are broken in the decompression hole; Ring memes with small particle size are especially prone to uneven particle length due to the length of the decompression pore.

The position or angle of the cutter is unreasonable.

The size of the pellets produced by the feed pellet machine is different Improvement measures: The feeding amount is small and uneven when the production is just opened and the production is about to end, resulting in a short pellet length, and if the requirements are high, it should be picked out. In the production process, the feeding volume and steam conditioning should be kept stable, the number of cutters should be matched with the output, and the output should be sacrificed if necessary to ensure the appropriate particle length.

Adjust the pressure roller and adjust the screw to make the gap of each mold stove Kaili roller consistent. The new ring die should be equipped with a new pressure concealment roller, and the wear amount of each pressure roller in use should be consistent; If the axial wear of the pressure roller and ring die is inconsistent, the high place should be polished off if necessary. Repair the material guide port of the ring die; Clean up the blocked holes on the ring die in time.

When designing the ring die, along the axial direction of the ring die, the compression ratio of the 3 rows of holes at both ends can be 1 2mm smaller than that in the middle (according to the formula and particle size selection).

Summary. The more effective method is to boil the ring die with oil, use an iron oil pan, put in the waste engine oil, put the plugging mold in the oil pan, so that the plugging mold hole is all immersed in the oil, and then heat at the bottom of the oil pan until the material in the plugging mold hole has a burst sound, that is, take out the plugging mold, reinstall the machine after cooling, adjust the gap of the die roll, and re-start it according to the operation requirements of the granulator, so that the material in the plugging mold can be quickly cleaned up, and the finish of the mold hole will not be damaged.

My question to you, it takes a little time to type, please be patient.

Hello. The hole of the ring die of the pellet mill must have a taper. Common ring die holes mainly include straight holes, stepped holes, outer conical holes and inner cone holes.

How to get through the ring die blockage of the granulator.

The more effective method is to boil the ring die with oil, use an iron oil pan, put in the waste engine oil, put the plugging mold in the oil pan, so that the plugging mold hole is all immersed in the oil, and then heat the bottom of the oil pan to the plugging mold hole to send a key to punch the material with a burst sound, that is, take out the plugging mold, reinstall the machine after cooling, adjust the mold roll gap, and re-start according to the operation requirements of the granulator, so that the material in the plugging mold can be quickly cleared and cleared, and the finish of the mold hole will not be destroyed.

There are many reasons for this, and the common ones are.

1.The moisture of the material is not suitable, and it is most suitable to control the moisture between 10% and 15%.The mold and the roller are seriously worn, and the mold and roller are wearing parts, which should be replaced after a period of operation.

3.The mold compression ratio is not suitable, different materials need different compression ratio molds, and the replacement material molds should also be replaced.

4.The spacing between the mold and the pressure roller is not appropriate, and the pellet machine promotes the pellet forming through the extrusion of the pressure roller and the mold, and the spacing can be adjusted appropriately in order to produce normally.

5.The material has a high crude fiber content, and the small pellet machine is not suitable for pressing the crude fiber material.

If the ring die granulator uses two blind screws on the eccentric wheel in the middle of the pressure wheel to adjust the pressure; The flat die granulator is a threaded wire column M100 center adjustment mechanism, with a top force of 100 tons, stable falling, soft impact and uniform pressure. It can be automatically adjusted in two ways: rotary manual and hydraulic automatic.

From the comparison between the flat die and the ring die, we can see that the pressure of the flat die is greater than that of the ring die, so it is better to use the flat die for the coarse fiber that is light and difficult to form materials such as sawdust and straw.

Ring die pellet machine is widely used in large, medium and small aquaculture, grain and feed processing plants, livestock farms, poultry farms, individual farmers and small and medium-sized farms, farmers or large, medium and small feed processing plants.

Ring die pellet machine (also known as: ring die pellet feed machine, ring die pellet feed molding machine), belongs to feed pelleting equipment. It is a feed processing machine that directly presses pellets from crushed products such as corn, soybean meal, straw, grass, and rice husks.

Ring die pellet mill is the main feed machinery and equipment for the production of pellet feed, and its performance determines the feed processing output to a large extent, and occupies a very important position in the feed processing process.
