Improvement of technological line of production of organic-mineral fertilizers by developing new equipment of vibration action for the realization of the process of fine grinding of bulk raw materials.

The technological principles of production of highly active organo-mineral fertilizers are substantiated. It is established that one of the promising means of intensifying this production and increasing the quality indices of the output products is the use of vibrating mills that allow modification of the structure of mineral raw materials in the course of its processing.

A number of principal schemes have been developed for the implementation of the progressive grinding of coarse-grained materials provided that the specific energy consumption is reduced for the production of highly dispersed materials. Experimental studies of influence on the final chemical composition of organo-mineral fertilizers prepared.

The main stages of biogas production are analyzed and the technology of preparation of organo-mineral fertilizers based on a liquid substrate from a biogas plant and related mineral impurities such as raccoon, phosphorus ore and glauconite is proposed.

A fundamentally new scheme of a vibrating mill for crushing bulk raw materials, which allows to carry out the process of fine grinding of large piece material, provided that the specific energy consumption is reduced for its processing.

As a result of the variational estimation of the influence of the accompanying mineral impurities on the final chemical composition of the initial organomineral fertilizer it was established that: the molten shellfish increases the calcium content by 10,6 times, reduces potassium content by 4.3 times, phosphorus – by 2.6 times, and nitrogen – in 6,1 times; phosphorus ore increases the calcium content by 10.2 times, phosphorus – by 1.6 times, decreases by 4.2 times, and nitrogen content – by 6.1 times; glauconite increases the content of phosphorus 2.2 times, reduces potassium content by 4.6 times and nitrogen – by 1.5 times.
