    Selecting Equipment and Materials of Construction for Fluid Fertilizer Plants
    (1977-10) Kimbrough, Homer L.; Hubert L. Balay
    This paper discusses the selection of equipment and materials for construction of fluid fertilizer plants. With the growing popularity of fluid fertilizer production, many new manufacturers are seeking guidance on equipment selection. The paper emphasizes the importance of considering factors such as the type of liquid fertilizer, production rate, fertilizer season length, and equipment usage. Projection of production needs over 5 to 10 years is recommended to avoid selecting inadequate equipment. The authors recommend selecting pumps, pipes, storage tanks, and mix tanks based on the characteristics of the fertilizers and operational requirements. The paper also highlights the significance of proper support, ventilation, and maintenance practices for maximizing the lifespan of the equipment. Overall, the information presented aims to assist prospective fluid fertilizer plant owners in making informed decisions about equipment selection and construction materials.

    Some Liquid and Bulk Blending Fertilizer Facilities Now in Existence
    (1963-09) Achorn, Frank P.
    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.
