METHOD OF RECYCLING AGRO-INDUSTRIAL WASTE Russian patent published in 2008 - IPC B09B3/00 B03B7/00 A01C3/00 

FIELD: agriculture, technological processes.

SUBSTANCE: in the method of initial agro-industrial waste before their loading in the drying chamber are preliminary regulated in water and/or reusable solutions. Through the formed suspension is bubbled compressed air, saline waste material of magnesium and/or potassium production, surface-active substances - water-repelling additives. The clarified liquid phase merges from the lower zone of storage capacity in the holding tank, and the partially-dehydrated agro-industrial waste are unloaded from storage tank in the preliminarily dispersed ejector state, and then it is loaded into the drying chamber. A gas heat-carrier is submitted into the drying chamber, thermal treatment and drying of waste with the subsequent unloading. As salt waste are used the waste products of the dehydration of carnallite, the slimes of carnallite chlorinators, used electrolyte of the process of electrolysis of magnesium from carnallite raw material and sub-standard dust fraction of the process of crushing and/or granulation of potassium chloride.

EFFECT: increase in the efficiency of processing of agro-industrial waste and increase in the productivity of the process.
