New process of BB fertilizer production Qinhuangdao Sannong Machinery Equipment Co., Ltd. Zhang Zhu Abstract: This paper proposes a new process of BB fertilizer production—quantitative batching, mixing and packaging of single-bags, based on the analysis of the material diversion caused by the difference in material density and particle size in the current production of BB fertilizers. As a new process. According to the characteristics of the new process, the company developed and developed a new integrated equipment for BB fertilizer production. The equipment has proved through many years of production practice: the equipment runs smoothly, the dosing precision is high, and the product quality is stable. It has the advantages of less investment, low production cost and high production efficiency. Key words: ingredients, mix, package 1. BB fertilizer development prospects BB fertilizer is a new type of fertilizer developed in China in the 1980s. It indicates that China's agricultural fertilization and fertilizer production have entered a new stage and level. With the continuous development of agricultural production, farmers have also continuously improved the level of scientific farming and scientific fertilization. They have become more and more aware of the profound meaning of “to produce large quantities, relying solely on fertilizers as their homeâ€, and thus the concept and level of fertilization. It is also constantly changing and developing. From single nutrient-rich fertilizers to multiple nutrient-rich fertilizers, from the single application of phosphate fertilizers and nitrogen fertilizers to the application of compound fertilizers containing nitrogen, phosphorus and potassium nutrients, a gradual transition from the application of low-concentration fertilizers to the pursuit of high application concentrations Multi-complex fertilizer. In the past, the era of “relying on high yields and relying on old diammonium in the United States†has come to an end. With the increase in the level of scientific fertilization in our country, the output of grain has jumped once again, from the past two to three hundred pounds per mu. This is a leap in leapfrog. If there is no improvement in the level of scientific fertilization, it is unthinkable. Today, with the rapid development of our national economy, all walks of life are pursuing high efficiency and low consumption, and agriculture is no exception. In the past two years, the information on the agricultural resources markets in various regions has told us that farmers are hoping and calling for us to produce for them. Nutrient high-concentration BB fertilizer (45%, 50%, 55%). This shows that farmers not only recognize the BB fertilizer, and in the pursuit of high-concentration BB fertilizer, that high-concentration BB fertilizer is low-yield and high-yield fertilizer. BB fertilizer is a kind of fertilizer with different processing methods in compound fertilizers. BB fertilizer has been developed in parallel with other compound fertilizer varieties. However, due to the low production level in the past, the development speed is slow, and the annual production only accounts for the production of compound fertilizers. The total amount of 15%, while in the United States BB fertilizer production and sales accounted for about 85% of production fertilizer. This gives us an inspiration. The BB fertilizer market has a lot of potential space in our country. In the past two years, with the upgrading of high-concentration compound fertilizers, the production of such high-concentration high-concentration compound fertilizers (45%, 50%, and 55%) using a granulation process is bound to result in new granulation and drying processes. The intractable technical problems will inevitably lead to high energy consumption, low efficiency, and high costs of production, which will inevitably make it increasingly disadvantageous in the market competition for high-concentration fertilizers. The production of BB fertilizer is just the opposite. Compared with the production of low-concentration compound fertilizers, the production and processing costs of high-concentration BB fertilizers will not only not increase, but will decrease accordingly. Therefore, it will inevitably occupy certain advantages in the competition of the compound fertilizer market. . It is not difficult to see that this increasing demand for high-concentration compound fertilizers has brought new opportunities for the development of BB fertilizer production. In addition, due to the simple process of BB fertilizer production, it is also more suitable for the production of variable-formula fertilizers and various special fertilizers that change at any time. In addition, China has invested a lot of manpower and financial resources for the development of the fertilizer industry in recent years. Several sets of production equipment for large-particle urea and granular potassium fertilizers have been put into production. This also provides quality assurance and raw material guarantee for the production of BB fertilizer in the future. Therefore, the production and market prospects of BB fertilizer are good. 2. Production status of BB fertilizer At present, China's BB fertilizer production currently can be divided into two broad categories: one is intermittent; the other is a continuous type (pictured). Intermittent computer batching - Upgrading - Intermittent mixing - Upgrading - Bag counting - Packaging (interrupted) Continuous computer batching - lifting - roller mixing - lifting - bag measurement - packaging (continuous type) But no matter what kind of form they have a common shortcoming, but also affect the fatal disadvantage of BB fertilizer development - in the process of repeated upgrades of materials and sub-bags, due to the different proportion of the material and particle size, resulting in the material Segregation. The ingredients may be completely accurate and the mix is ​​completely uniform. However, due to the different materials in the lifting process, due to the different density and particle size of different materials, the different line speeds will result in the grading of the material flow, which will eventually result in imbalance of the nutrient content of the finished product fertilizer, not only causing the product quality to be unqualified. It also seriously affected the effectiveness of fertilizers. But at present, BB fertilizer production still only stays in the BB fertilizer production and shaping equipment and equipment formed by these two kinds of technological processes. There are many companies that even adopt primary workshop-style production methods such as pound weighing, mixing with cement mixers, manual bagging, and portable sewing, which are in sharp contrast with the current development of the fertilizer industry and the requirements of agricultural production. It does not adapt. 3. New Production Process of BB Fertilizer In view of the shortcomings and shortcomings in the current BB fertilizer production, Qinhuangdao Sanon Modernization Machinery Equipment Co., Ltd. proposed a new production process for BB fertilizer and developed an integrated production device. That is a single bag quantitative ingredients, mixing, packaging new technology (Figure 3). Single bag ingredients - single bag mixing - packaging The process uses a single bag quantitative ingredients, mixing and packaging in one, simplifies the process flow; shortens the movement of the mixed material, which reduces or overcome the shunt phenomenon of the material in the run, and improves the product pass rate. The shortening of the process flow and the use of a fully automated integrated production facility greatly increase the production efficiency and reduce the consumption, that is, the production cost is reduced, which provides a favorable space for the development of BB fertilizer and market development. Compared with traditional BB fertilizer production, this new process has the following obvious advantages: 1) Less investment As the new process uses less than two lifts and a bag weighing scale than the traditional process. It is also suggested that the equipment be placed underground, so the new process does not impose strict requirements on the plant. 2) high precision of ingredients Because the new process does not have processes such as repeated feeding and bag counting, it integrates single-bag dispensing, mixing, and packaging to avoid material shunting and overcomes the impact of product specific gravity and particle size on product mix accuracy. . Guarantee the accuracy of the single bag, also guarantee the quality of each bag. 3) Low production cost (an annual output of 100,000 tons) a) Low loss of nutrient content: In order to ensure the qualified rate of products and take into account the instability of production, most manufacturers generally add about one nutrient to the prescribed nutrient content in the production process. If a nutrient content is 50 yuan, / Ton, 100,000 tons of BB fertilizer will be produced in a year, and at least 5 million yuan will be wasted. The new process does not need to increase the content or the content of the nutrient content on the basis of the provisions to guarantee the qualified rate of the market spot checks. b) Low power consumption: The total power of the new production process is about 8 kilowatts. The total power of the old craft is about 45 kilowatts. c) Low maintenance costs: Since the new process saves about 30% of the equipment compared to the old process. Therefore, maintenance costs will also be greatly reduced. 4) High production efficiency Due to the new process, a great deal of equipment is saved. As a result, the failure rate of the entire system in the production process is reduced, and the production efficiency is improved. In a word, the integrated equipment for automatic batching, mixing and packaging developed according to the new process flow not only improves production efficiency and reduces production costs, but also guarantees product quality, improves economic efficiency for enterprises, and creates for the development of agriculture. Inestimable social benefits. 4. Conclusion Although China's current use of BB fertilizer is still not very large, but with the increase of BB fertilizer production process. More farmers will recognize the quality of BB fertilizers, and more manufacturers will see its potential profits. I think that when China's BB fertilizer consumption accounts for 50% of the total amount of fertilizer, China's agriculture will be a qualitative leap compared to the present.
