Analysis of the influence of low quality ring mould on granulator
Analysis of the influence of low quality ring mould on granulator
2023-02-11
With the rapid development of the feed industry, feed enterprises have been covered all over the country, and the production of granular feed has also become the main product to promote the development of animal husbandry. At the same time, the sales of Zhengchang granulator also popularize the domestic market, and sell the international market hot.     At present, because of the popularity of feed enterprises and the increase of pellet feed production, the demand of granulator ring mold has also increased. Therefore, some small manufacturers of poor quality ring mould also flow into the market, and some feed production units are attracted by their low price, but it should be known that the poor quality ring die has rough processing and low service life, and it is important to have the disadvantages of low imitation precision, poor concentricity and big jump of ring die face. If the granulator is used for a long time, the service life of the granulator will be greatly shortened. According to the recent investigation of my after sale service department, with the unit of non Zhengchang original ring mould, after a few months the granulator generally runs, the parts of each part appear different degrees of wear and tear, and the frequency of the bearing damage is high, the oil seal oil leakage is serious, the main engine often appears malfunction, resulting in the unstable work of the granulator and low production capacity. Elephants. This is actually like the current market mobile phone, although the price is only 1/3 of the brand machine, but it is more than five times more harm to the head brain radiation, the same reason, why the use of poor quality ring mold will shorten the life of the granulator? The price ratio is not good, because there are many reasons.     1. the low quality ring model is in pursuit of low sales price, so it has some limitations on the selection of billet, it is impossible to select high quality materials and only choose low quality and low price steel as raw material, but the structure of the billet is not tight, the toughness is not required and the wear-resistance is poor, and the life span of the ring made of this steel billet  Short and easy to crack. If such a ring mold is chosen, it will not only waste the capital investment of enterprises frequently changing moulds, but more serious is the hidden danger of production safety.     2. poor quality ring mold processing equipment is rough, it is impossible to have the accuracy of machining internal and external circles, such as Zhengchang ring die machining. At present, most of the ring mold manufacturers in the ring mold finishing, most of the use of the old type lathe, the equipment is old, the processing precision is not up to the requirements, and then this kind of ring mold making itself is imitated, the main matching surface precision and processing size is difficult to ensure accurate, like the ring die and the hoop of the combination surface, processing only In order to have more than ten wire errors, the hoop can not hold the ring die tightly, which causes the ring mould to shake and friction in the high speed operation, and the hoop and the empty axis drive wheel will be damaged simultaneously, and the vibration of the fuselage appears.     3.The machining technology of the ring die hole of 3. granulator is very particular. For example, Zhengchang ring die drilling equipment is made of gun drilling and drilling. It has the advantages of neat arrangement of die holes and smooth surface of hole wall. But the poor quality ring mold hole machining mostly use small drilling machine manual operation, the inner wall of the hole is rough and there is rib, the ring die compression ratio is different, forming the ring die material difficult, easy to plug the machine and other conditions, so that the electricity consumption increases, the production capacity falls, the particle appearance is not smooth, the finished material length is uneven, especially when the machine plugging, ring die  The temperature of the extrusion chamber is rising rapidly, which makes it easy to burn down the roller bearings and spindle bearings and increase the working load.      4. ring die quenching process is an important part of the ring mold manufacturing. The quenching process of Jumeila ring die is very particular. All the vacuum quenching furnace and multi-purpose quenching furnace are used. At present, it is difficult to have these advanced equipment in the small ring mold production plant. It is usually quenched by the soil well type furnace. This kind of equipment can not automatically control the temperature of the ring die quenching. It causes the hardness of the surface to be inconsistent after the ring die quenching, and the deformation coefficient is large and the ring die is easy to lose circle. It will produce pressure roll frequently impact ring die, making the vibration noise of the granulator increase, it is also an important factor of the damage of the spindle and the empty axis. Once the bearing of the spindle and the empty axis is damaged or running inside and outside, the spindle and the empty axis may be scrapped. For example, the wear of the bearing hole of the host box will not only produce the production of the granulator, but the output is obviously reduced. Low, and it will cause the granulator to not work properly.      5. because the poor quality ring die processing is mostly imitation, its processing precision can not be controlled, plus the accumulation of all aspects of error, such as the long-term use of this type of ring mode, the normal work of the granulator will be seriously affected, and can not reach the purpose of safety, high production, low consumption of the granulator at all. Careful calculation of an account, the use of poor quality ring model, although the purchase price is low, but the granulator often fails, parts and bearings are often replaced, production reduction, electricity consumption increase, manpower waste, will make the economic benefits of the enterprise to be affected, in order to make your granulator in the feed production process to achieve the quality of the product quality excellence. High output, low power consumption, safe production, full play of the working efficiency of the granulator, we suggest that the best selection of the ring die of the granulator is to choose the original standard and high quality ring mold.

7 factors that cause mouldy feed production can not be ignored.
7 factors that cause mouldy feed production can not be ignored.
2023-02-11
Technical factors of feed production caused by mouldThe granulating mechanism is quick and effective, and the filter with special holes is designed for careful screening. The friction filter rod can crush the solid particles, which is widely used in pharmaceutical, chemical and food industries.This machine can replace the swing granulator and is a new generation granulator.In the pelletizing production of granulator, there will sometimes be abnormal appearance of granules, for inexperienced or new feed manufacturers, sometimes can not find the crux of the problem.The following seven common abnormal appearance of the granule produced reasons and the improvement methods are introduced to you, for the feed production for comparison reference.1. The granular material is bent and has many cracks on one sideThis phenomenon usually occurs when particles leave the ring mold.In production, when the cutter is located far away from the surface of the ring die and the blade is blunt, the particles are knocked or torn by the cutter rather than cut off when extruding from the die hole. At this time, some particles are bent to one side and many cracks appear on the other side.The particles tend to break from these cracks as they enter the cooler for cooling or transportation, resulting in too much pellet powder produced.Improvement methods:A) increase the compression force of ring mould on feed, that is, increase the compression ratio of ring mould, so as to increase the density and hardness of granular material;B) pulverize the feed raw materials more finely. If molasses or fat are added, the distribution uniformity of molasses or fat should be improved and the added amount should be controlled to improve the compactness of granule and prevent the feed from being soft;C) adjust the distance of the cutting knife from the surface of the ring mold, usually the distance between the blade and the outside surface of the ring mold is not greater than the diameter value of feed particles produced, or change to use a sharp cutting blade. Thin blade can also be used for particles of small diameter, and the thin blade can be closely produced on the surface of the ring mold.D) the use of bindlike granulation AIDS helps to improve the cohesion within particles.2. Horizontal cracks cross the whole granuleSimilar to the phenomenon in case 1, the crack occurs on the cross-section of particles, but the particles do not bend.This may occur when a fluffy feed containing more fiber is granulated.This kind of granular material is usually when the feed is squeezed into the grain hole of the circular mould, because it contains the fiber with a longer diameter than the hole, when the grain is extruded, the expansion of the fiber makes the granule produce a cross-section crack on the cross section, producing the fir bark shape of the feed.Improvement methods:Increasing the compression force of annular mould to feed, that is, increasing the compression ratio of annular mould;Control fiber comminution fineness, its maximum length can not exceed one third of particle size;Reduce the output to reduce the speed of feed passing through the mold hole and increase the compactness;Longer quality adjustment time, use multilayer or caldron type quality regulator;When the powder is too moist or contains urea, it is also possible to produce fir bark like feed appearance, the added water and urea content should be controlled.3. Vertical cracks are produced in granular materialsSome feed formulations contain fluffy and slightly elastic raw materials, which will absorb water and expand when being quenched by the tuner. After being compressed by the circular mould, the raw materials will spring apart due to the action of water and the elasticity of the raw materials themselves, resulting in vertical cracks.Improvement methods:Change the formula, but this may increase the cost of raw materials;To control the quality of the steam used in tempering and to minimize the amount of added water by using more saturated dry steam;Reduce the yield or increase the effective length of the die hole, so as to increase the time of the feed in the die hole;Adding a binder also helps to reduce the occurrence of vertical cracks.4. The granular material produces radiant cracks from a source pointThis kind of appearance that large particles of raw material is contained in grain, these large particles on raw materials, it is difficult to fully absorb moisture in the water and heat, is not as easy as other thinner material softening, and during cooling, due to the different degree of softening, lead to the difference of shrinkage, so as to produce radial crack, makes the pulverization rate increase.Improvement methods:The thickness and evenness of powdery feed raw materials should be properly controlled, so that all the raw materials can be fully and uniformly softened.5. Uneven surface of granular materialThis situation lies in that the powder used for granulating contains large particle raw materials that have not been crushed or semi-crushed. Due to insufficient softening during the tempering process, the particles are hard and large, and cannot be well combined with other raw materials when passing through the mold hole of granulator, which makes the particles appear uneven.Another case may be that the tempered material is mixed with steam bubble, which makes the feed produce air bubble in the process of compacting into particles. When the particles are extruded to the circular mould, the bubble will burst due to the pressure change and the bump phenomenon will occur on the surface of particles.This can happen to any feed containing fiber.Improvement methods:Proper control of the size of powdery feed so that all ingredients can be fully softened in the conditioning;For raw materials with more fiber, do not add too much steam into this formula because it is easy to inclusion steam bubbles.6. Whisker granulesWhen in the production of granular material, if join the steam of too much, too much steam will accumulations in fiber or powder, particles in extrusion ring die, due to the pressure of dramatic change make particles burst cut the fibre or granular materials convex surface, forming a prick the hand whiskers, especially in the production of high starch and fiber content of the feed, the use of steam, the more the more serious.Improvement methods:Good quality.When the high-starch, high-fiber feed is granulated, the low-pressure steam (0.1-0.2mpa) should be used so that the water and heat in the steam can be fully released for the feed absorption.If the steam pressure is too high, or after the pressure reducing valve downstream piping distance conditioning device is too short, generally should be greater than 4.5 m, the steam will not necessarily good release the moisture and heat, so some of the steam accumulations of feed raw materials, after quenched and tempered when granulating causes described above whiskers particle effects, anyhow should pay special attention to the steam pressure control and pressure reducing valve installation position is correct.7. Individual particles or inter-individual particles have different colors, commonly known as "flower material"This situation is relatively common in the production of aquatic feed, which mainly shows that the color of individual particles extruded from circular mould is darker or lighter than that of other normal particles, or the surface color of individual particles is inconsistent, thus affecting the appearance quality of the whole batch of feed.The reasons for this phenomenon are as follows:A) due to the complexity of aquatic feed formula ingredients, raw material variety, the relatively small amount and some ingredients, raw materials mixed in, if the mixing machine mixing effect is not ideal, it is difficult to ensure that raw material of mixed into the granulator is uniform, thus in the process of adjusting quality and granulating, the moisture, temperature and pressure, under the function of physical and chemical changes in raw materials, color change leads to different components of the raw material, produce "flower", this kind of situation in the feed formulation containing raw material change color to the change of temperature and moisture sensitive when more outstanding.B) inconsistent moisture content of raw materials used for granulation.In the production process of aquatic feed, in order to make up for the loss of moisture of raw material after ultra-fine grinding, a certain amount of water should be added to the mixing machine, which is then transferred to the conditioner.Some feed manufacturers are simple in the process, directly pour a certain amount of water in the mixer, rather than using a special sprinkler evenly injection, so it is difficult to make the feed after mixing evenly distributed water.When this mixture of raw materials enters the quenching machine, since it is impossible for the conditioner to further distribute the water evenly in a short time, under the action of steam, the curing effect of all parts of the feed after the quenching is inconsistent, and the color change after granulation is inconsistent.C) there is recycled material in the silo for repeated granulation.After granulating of grain after cooling and screening, to become a finished product, after the screening of fine powder or granule material often enter the granulating technological process in, usually into the mixer or DaiZhi grain warehouse, because the material is a new conditioning and granulating, after quenched and tempered if uneven or inclusions and other raw materials mixed with small particles of material back to the machine, for some feed formula, sometimes produce "flower".D) the inner surface finish of the circular mould aperture is inconsistent.Due to the inconsistency in the finish of the die hole, the resistance and extrusion pressure of the particles during extrusion are different, and the color change is inconsistent.In addition, some annular model holes have burrs on the wall, and particles scratch the surface during extrusion, resulting in different color surface of individual particles.For the four reasons listed above, it is clear that the improved method is to control the mixing uniformity of the components in the formula and the mixing uniformity of the added water.Improve the quality control, control the tempering temperature when necessary, and adopt a lower tempering temperature to reduce the color change;Control the machine material. For the formula easy to produce "flower material", try not to use the machine material for direct granulation.Adopt quality guaranteed ring mold, control the finish of the mold hole, and when necessary, sand the mold hole before use.In summary, seven representative manifestations of abnormal appearance of granules in feed production are discussed above, and some abnormal appearance of granules are not discussed here because they are not representative.From the above discussion, it can be seen that the causes of these phenomena are various, and they are not completely isolated from each other. This requires us to analyze and grasp the key points of these problems before we can solve them.
