Operation Analysis and Improvement of Technological Lines for the Organic Fertilizers Production

Abstract

The authors conducted an analysis of technological lines operation in the Russian regions. They reasoned the relevance of scientific research on the development and design of technological lines using modular equipment for the humic and complex fertilizers production. A technical problem unresolved from a scientific point of view was revealed – the lack of industrial production of specialized equipment for humic fertilizers obtained on the basis of deep processing of organic raw materials. ( Research purpose ) To determine the optimal composition of modular equipment using digital technologies for the design of industrial processing lines for the organic raw materials processing (peat, sapropel, brown coal and biohumus) based on the technical specifications of the customer and the results of the experimental production lines. ( Materials and methods ) The authors studied the efficiency of the technological lines based on their technical capabilities. They studied the practical results of checking the dependence of the obtained products quality on the parameters and operating modes of individual units and assemblies. They used well-known private methods developed on their basis. ( Results and discussion ) The authors revealed some technical and technological deviations in the equipment operation: low level of organic raw materials purification when the vibratory separator was 85-90 percent, insufficient power of the disassembler – 3.5 kilowatts; fertilizers dispersion after the reactor exceeded 140 micrometers; the content of the ballast after filtration – 5-8 percent; the level of humic salts was low – from 5 to 10 grams per liter; trace element dosing system was not perfect. The authors suggested continuing the search for technical solutions for production without ballast humates using modular equipment. They identified the need to increase the productivity of technological lines from 1 to 2.5 tons per shift. ( Conclusions ) Based on practical experience in modernizing production lines, the authors suggested optimizing the composition of modular equipment purchased in the market for engineering products. They determined the basic principles of the modular design of technological lines that allowed using the Internet portal to increase production efficiency and obtain a product of demanded quality.
