The usage of Lisakovsk ore mining and processing enterprise concentrates in sinter burden is accompanied by a decrease of the sinter machines specific productivity of ArcelorMittal Temirtau JSC. The specific productivity is less than 0.8 t/m2·hour, whereas the sinter machines of world leading and Arcelor Mittal companies work with the specific productivity of 1.0 – 1.3 t/m2·hour. The low specific productivity of sintering machines is defined with low burden permeability. The gravitational-magnetic concentrate of Lisakovsk consists of oolites in amount of 93–94%. Their dimensions are 0.2 ÷ 0.8 mm. The concentrate is keeping low autohesion properties and influence on low permeability and low productivity of burden. This article shows the results of laboratory research of burden grain fineness optimization with adding of binders. The aim of research is to demonstrate how scientifically justified technological solution is able to increase and keep the permeability of pellet agglomerative sinter during caking in the conditions of using a mixture with a low autohesion characteristic of dissimilar and dispersed bulk solids. Due to this process it is able to increase specific productivity of sinter machines. For laboratory research bulk solids mixture was used which would correspond to the components and composition of averaged sinter production data of ArcelorMittal Temirtau JSC in 2016. The burden of sinter production is represented by dispersed bulk solids which consist of gravitational-magnetic concentrate of Lisakovsk (GMCL), concentrate of the Sokolovsk-Sarbaisk ore mining and processing enterprise, Atasu ore burden fields, Atansor, Kentobe and other, combined flux and coke slack. The properties of widely used binders are investigated within the laboratory research. They are bentonite, liquid glass, YPEEN, amino-acrylate, lime milk. The properties of binders are defined by pelletization of the sinter burden mixture components. These components are used as adding, as the establishment of their influence on the ability to pelletization and comparative analysis of the indicators for the purpose of selection and possible use in production conditions. To assess the autohesive properties, a basic experiment is performed without the additives. The amount of binder additives is determined within the limits while not affecting the cost of the technological process. The results of investigations show that the usage of an aqueous solution of dispersed lime as a binder has a significant effect not only on the autohesion of a heterogeneous mixture of slug raw materials but also the stability of the optimal grain fineness of the pelletized burden during sintering. As a consequence, it provides high specific productivity of agglomeration.
