The possibility in principle of using pulp and paper industry waste as a binder for pelletization flotation potassium chloride bases on conducted researches. Defined technical conditions of pelletization flotation potassium chloride using pulp and paper industry’s waste as binder provide product with good commercial qualities, which are yield of marketable fraction (85.71 %) and resistance of granule (29.51 N). The researches for studying conditions of baking were conducted and subsisted defects on granule surfaces. There are two kinds of defects. One of them is inner defect is represented as caverns and flaws. Another type of defects are outer defects. They are represented as crystallized structural arrangements in the form of coreless tube that has net structure and includes fiber and cubic shaped microcrystals. Granule defects form after baking them with temperature higher than 120ºC.

This article investigated the possibility of creating a new composite material for electrical products based on natural graphite as the main component with the addition of a plasticizer . Adding plasticizer necessary to solve technological difficulties pressing process products with a high content of natural graphite . This is due to large shear between the interphase graphite flakes . As the plasticizer used polyvinylacetate . The paper presents the technological aspects of production material and study the influence of the plasticizer on the composition, both qualitative and quantitative . Conclusions about the most appropriate ratio to the amount of graphite esmestvennogo adds plasticizer.
