METHOD OF MANUFACTURING GRANULATED ORGANOMINERAL FERTILIZER AND INSTALLATION FOR IMPLEMENTATION THEREOF Russian patent published in 2005 - IPC

FIELD: mixed fertilizers.

SUBSTANCE: invention aims at manufacturing organomineral fertilizers completed with trace minerals minimally remote from crop-growing areas. Method comprises mixing poultry dung with phosphorus-, nitrogen-, and potassium-containing components followed by adding trace minerals. Organic base of fertilizer comprises vegetative mass waste and wastes produced in bean and licorice seed threshing operations. Phosphorus-containing component includes double superphosphate from phosphorite flour and sludge originated from pig-breeding farm settlers. Nitrogen-containing component includes two to four-year decomposition poultry dung. Potassium-containing component includes manure from temporary-storage areas near pig-breeding farms. Sources of space minerals are ground and processed slime solutions, metallurgy waste, and naturally occurring bischofite solution. Homogenous mixture is supplemented by paraffin-containing refinery waste as binding substance. Mixing is carried out for 20-50 min and naturally occurring bischofite solution and paraffin-containing refinery waste are added into mixer at 60-90°C. Organic fertilizer manufacture installation comprises in series installed interconnected cinematic and mechanic raw material transportation means, dung accumulator, centrifuge connected over pipeline to effluent accumulator to withdraw liquid fraction, raw material stirring means, raw material hot-air driers, raw material hopper-accumulator, and finished produce-discharge conveyer. Installation is also provided with crusher for vegetative mass, bean and unconditional licorice seed threshing products, and containers, gate members hydraulically connected with containers, and pumps for supplying liquid paraffin-containing waste and bischofite solution. Installation is further provided with delivering hoppers to separately deliver phosphorite flour and complex powdered minerals from metallurgical etching waste slimes. Component stirring means is cinematically connected over screw transportation means to hoppers-accumulators for 2-4-year decomposition poultry dung and for 2-year decomposition cattle manure, centrifuge, and granulating extruder. The latter is connected to drum drier over conveyer band.

EFFECT: increased fertilizing value of product.
