This paper conceptualizes a machine that is used for mixing powder products used in building construction. The mixer is dimensioned and consists of three main parts: housing, mixer with blades and gear motor. The housing is dimensioned to have the ability to mix 1000 kg of product and the housing material is determined to be able to withstand the abrasion caused by the product components. The following parts have been dimensioned and placed in the appropriate place: openings on the housing necessary for unloading raw materials into the mixing process; openings for gravity unloading of products, inspection openings and structural openings (shaft holes, machine parts joints). A mixer with blades was designed in a way that it will homogenize the product as well as possible. The shaft and arms of the mixer are dimensioned with a calculation that takes into account the mass of the shaft and the torque during mixing. The material of the mixer shaft and blades is selected in such a way that it can withstand the abrasion of the product components. The motor and gear are selected according to the optimal gear ratio and the required number of revolutions to make the product as homogeneous as possible. The assembly drawings of the mixer are attached as well as all workshop drawings of the main dimensioned components of the mixer and information on all standard components such as bearings, screws, nuts, etc.
