Fertilizer Technology, Granulation of High-Analysis Fertilizers

Fertilizer Technology, Development of a One-Step Process for Production of Granular Triple Superphosphate

“…Nitrogen was supplied as anhydrous ammonia. The formulation was similar to one containing nongranular superphosphate tested in previous work (2). The overall input degree of ammoniation in this formulation was 3.9 pounds of ammonia per unit of available phosphorus pentoxide.…”

“…The pilot plant used in this work was the same as used in the development of processes for the production of granular high-analysis fertilizers (2). The only significant change required in the equipment to make it suitable for use in producing granular triple superphosphate was the installation of ducts for the removal of fluorine fumes from the granulator, crusher, and screens, and the addition of a cage mill following the roll crusher.…”

Fertilizer Technology, Production of Ordinary Superphosphate for Immediate Use in Ammoniation and Granulation Processes

“…Noller, Ward, and Huffman (71) have observed similar results with young calves. However, the gain and feed efficiency of young pigs fed soybean protein basal diets were improved by either the addition of proteolytic enzymes to the diet (6) or by partial prehydrolysis of soybean protein with enzymes (5).…”

“…The acidulation step was carried out in a pilot plant that consisted of a TV A-type funnel mixer (<S) and a continuous den of the Broadfield type. After a denning time of 1 hour, the fresh superphosphate was used in the production of granular fertilizers in the TVA ammoniation-granulation pilot plant (5).…”

Phosphate Ore, Fertilizer from Leached-Zone Ore

“…Ammoniation, Granulation, and Drying. The concentrated filtrate was processed to a fertilizer product very successfully in the TV7 A continuous ammoniation-granulation pilot plant (5). This type of equipment has been found to be adaptable to the ammoniation and granulation of a variety of fertilizer formulations and has been adopted widely in industry.…”
