With the rapid development of the feed industry, feed enterprises have spread all over the country, and pellet feed production has become the main product to promote the development of animal husbandry. At the same time, the sales of Zhengchang granulators have also spread to the domestic market and are selling well in the international market.
At present, due to the popularity of feed enterprises and the increase in pellet feed production, the demand for granulator ring molds has also increased. Therefore, the poor quality ring molds produced by some small manufacturers have also flowed into the market. Some feed production units are attracted by their low prices, but it should be noted that such inferior ring molds have rough processing, low service life, and important is the imitation precision. Low, concentricity, and large runout of the ring die face. If the granulator uses this ring mold for a long time, it will greatly shorten the service life of the granulator. According to a recent investigation by the after-sales service department, all the units that use the original ring mold of Zhengchang, the granulator generally runs for several months, the parts of the parts appear different degrees of wear, and the frequency of bearing damage is high, the oil seal leaks. Serious, the host often fails, causing the granulator to work unstable and low productivity. This is actually like the cottage phone on the market. Although the price is only one-third of the brand machine, it hurts the human brain more than five times. The reason is the same. Why use the inferior ring model? Shorten the life of the granulator? The price/performance ratio is not good, and there are many reasons.
1. The inferior ring mold pursues low sales price, so it has certain limitations in the selection of blanks. It is impossible to use high-quality materials. Only low-quality and low-priced billets can be used as raw materials. The molecular structure of such billets is not tight and the toughness is not up to To the requirements, the degree of wear resistance is poor, and the ring mold made of the steel billet has a short service life and is easily cracked. If such a ring mold is used, it not only wastes the capital investment of the enterprise due to frequent replacement of the mold, but also has serious production safety hazards.
2. The equipment in the inferior ring die processing is rough, and it is impossible to have the accuracy of solving the inner and outer circles in the process of Zhengchang ring die. At present, most of the ring mold manufacturers in the ring die finishing, the majority of the use of old-fashioned lathes, the equipment is relatively old, the processing accuracy is not up to the requirements, plus the ring mold itself is imitation, the main mating surface accuracy And the processing size is difficult to ensure accuracy, like the combination of the ring mold and the hoop, as long as there are more than a dozen wire errors in the processing, the hoop does not hold the ring mold, resulting in the granulator shaking and rubbing during high-speed operation. The hoop and the air shaft transmission wheel are damaged at the same time, and the body vibration phenomenon occurs.
3. The processing technology of the ring die hole of the granulator is very particular. For example, the Zhengchang ring die drilling equipment is made by using imported gun drills. It has the advantages that the die holes are arranged neatly and the hole walls are as smooth as the mirror surface. However, most of the inferior ring die hole machining is manually operated by a small drilling machine. The inner wall of the hole is rough and ribbed, and the compression ratio of the ring die is different, forming a ring die discharge difficulty, and it is easy to block the die plugging machine and the like, so that the electric power consumption is increased. The production capacity is reduced, the appearance of the particles is not smooth, and the length of the finished material is uneven. Especially when the machine is blocked, the temperature in the extrusion cavity of the ring die rises rapidly, and the pressure roller bearing and the spindle bearing are easily burned out, and the working load is increased. The size of the granulator is worn faster.
4. The ring die quenching process is an important part of the ring die making process. The Zhengchang ring die quenching process is very particular, all of which use the American vacuum quenching furnace and the Japanese multi-purpose quenching furnace. At present, it is difficult for small-sized ring mold production plants to have these advanced equipments. Generally, they are quenched by a soil-well type furnace. This equipment cannot automatically control the temperature of the ring mold quenching, resulting in inconsistent hardness in the surface after quenching of the ring mold, and the coefficient of deformation. Larger, the ring mold is easy to lose the round. The granulator using this ring mold will cause the pressure roller to frequently hit the ring mold during operation, which will increase the vibration noise of the granulator, which is also important for the damage of the main shaft and the hollow shaft. Factor, once the bearing of the main shaft and the empty shaft is damaged or the inner and outer rings are run, the main shaft and the empty shaft may be scrapped. If the bearing hole of the main box is worn, not only will the granulator work weakly, the output will be significantly reduced, and the system will also be caused. The pellet machine is not working properly.
5. Because inferior ring mold processing is mostly imitation, its processing accuracy can not be controlled, plus the accumulation of errors in all aspects, such as the long-term use of this ring mold, the normal work of the granulator will be seriously affected, simply can not be achieved Granulator safety, high yield, low consumption. Calculate the account, use the inferior ring model, although the purchase price is lower, but the granulator often fails, the parts and bearings are often replaced, the output is reduced, the power consumption is increased, the manpower is wasted, and the economic benefits of the enterprise are affected. In order to make your granulator achieve high quality, high output, low power consumption and safe production in the feed production process, we should give full play to the working efficiency of the granulator. It is best to use Zhengchang original standard quality ring mold.
