| Abstract | The establishment of liquid and bulk-blending fertilizer plants has increased significantly over the past decade. These plants, with capacities ranging from 2,000 to 5,000 tons of fertilizer per year, offer low investment and operating costs, making them attractive to nitrogen, P2O5, and K2O producers. This presentation provides a general discussion of the equipment used in manufacturing liquid and bulk-blended fertilizers, focusing on plants currently in use. Liquid fertilizer plants can be classified as liquid hot-mix or liquid cold-mix plants. Liquid hot-mix plants neutralize phosphoric acid with aqua ammonia or anhydrous ammonia, generating chemical heat. Liquid cold-mix plants mix high-phosphate liquid base solutions with urea-ammonium nitrate and potash. The presentation describes the equipment and processes involved in these types of plants. Bulk blending plants, which have gained popularity in the Midwest and other regions, involve dry-mixing solid raw materials to create customized mixtures with different nutrient contents. The raw materials are weighed, mixed, and conveyed to bulk trucks or bagging machines. The various types of mixers used in bulk blending plants, such as rotary mixers, mixing screw conveyors, ribbon mixers, and gravity-flow mixers, are discussed. The presentation also touches on materials handling systems, weighing devices, and different mixing techniques used in these fertilizer manufacturing facilities. While other types of liquid plants and blending systems are available, the focus is on the plants currently in general use. | |
