Stainless steel compound fertilizer production line sent to Paraguay
This week, we sent a stainless steel compound fertilizer conversion production line to Paraguay, South America. This customer is the first time to cooperate with us, and it is a relatively large customer we have cooperated with. At first, we recommended the compound fertilizer production line produced by national standard carbon steel to the customer, but the customer believed that the compound fertilizer production line of carbon steel would become less and less durable with the corrosion of raw materials, and the customer wanted compound fertilizer with good corrosion resistance. For the production line, we recommended the all-stainless steel compound fertilizer production line to the customer. At first, the customer felt that the price was too high, and due to the impact of the epidemic, the freight rate continued to rise, so the matter was shelved. Later, the customer found the products of other companies in the same industry for price comparison, and found that although our machine is a little higher than that of the same industry, the quality of our machine is guaranteed, and we will report the production process of the machine to the customer at any time. Very satisfied, place the order to us.
The raw material of compound fertilizer production line is suitable for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, etc. The product has a high granulation rate. It can produce compound fertilizers of various concentrations and types (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.). Especially rare, ammonium bicarbonate series compound fertilizer granulation.
1. Ingredients of raw materials: Generally, urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, common calcium), potassium chloride (potassium sulfate) and other raw materials can be selected in proportion Equipment (mainly based on local market demand and local soil test results);
2. Mixing and stirring: Mix the prepared raw materials evenly to improve the uniform fertilizer content of the fertilizer particles as a whole, and use a horizontal mixer or a disc mixer for mixing and stirring;
3. Agglomeration and pulverization: pulverize the uniformly mixed raw materials into large agglomerates, etc., to facilitate subsequent granulation processing, mainly using chain pulverizer, etc.;
4. Material granulation: The material after being evenly stirred and pulverized is sent to the granulator through the belt conveyor for granulation (a rotary drum granulator can be used, or a pair of roller extrusion granulator and a disc granulator can be used. Granulator, etc.);
5. Primary screening: Preliminary screening of semi-finished particles, and unqualified particles are returned to the mixing and stirring process for reprocessing. Generally, a drum screening machine is used;
6. Granule drying: The granules made by the granulator and subjected to primary screening are sent to the dryer, and the moisture contained in the granules is dried to increase the strength of the granules and facilitate storage. Generally, a rotary drum dryer is used;
7. Particle cooling: The temperature of the dried fertilizer particles is too high, and it is easy to agglomerate. After cooling, it is convenient for bagging, storage, and transportation. It is cooled by a cooler;
8. Secondary classification of particles: the cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out, which can be screened by a secondary drum screener;
9. Finished granule coating: coating qualified products to increase the brightness and roundness of the granules and make the appearance more beautiful. Generally, a coating machine is used for coating;
10. Quantitative packaging of finished granules: The coated granules, that is, the finished granules, are sent to the silo through a belt conveyor for temporary storage, and then connected to an electronic quantitative packaging scale, sewing machine and other automatic quantitative packaging and sealing bags, and stored in a ventilated place to achieve full automation .
