The method for measuring the resolution is implemented using a test film assembly made in the form of a glass photographic plate, on the surface of which a schematic drawing with linear elements of a given width and the distance between them is applied. This test film assembly is placed on the surface of the photosensitive stencil material and exposed to it with subsequent development. An image is obtained through the stencil, a graphical model of the blank elements of the stencil and the image is built in the coordinate system a-d, where a is the width of the reproduced element, d is the distance between neighboring elements. The obtained curves are analyzed, intersection points are found and the resolution limit of the screen printing process is calculated at the current technological parameters and materials used. The claimed method makes it possible to determine the influence of specific factors of screen printing on the reproduction accuracy of discrete elements through a screen printing plate.  
     EFFECT: definition of a favorable range of values is carried out, which guarantees high-quality reproduction of elements of the appropriate width and distance between them, as well as determining those cases when using screen printing with the current parameters and materials is not feasible.

Coal fines are fed into the first flow of charge in amount of 2–6 % of its consumption. Waste engine oil sludge in amount of 1–8 % of charge flow rate of first flow is mixed with sulfite-yeast brew in amount of 5–50 % of sludge weight, forming the main flow of free-flowing oil liquid, which is then heated. Mixture containing coal fines, charge and easy-flowing oil liquid is fed into drum mixer and mixed for 1–10 minutes, after which it is directed into compressed air flow. Zone occupied with charge and a zone free from charge are formed on the bottom of the pelletizer. Nucleation is carried out by sputtering the surface of the scull to obtain a dense layer of the charge in the charge-free zone. Said dense layer of wet charge is divided into nuclei by dividers ribs. Scull is cleaned from nuclei. Shell of pellets is formed by additional lumping of nuclei with charge of the second flow to pellets. Pellets are thermally treated.
