The analysis of mixture kinematics in the mixer body frame with a screw elevator with variable generatrix

Determination of Building Mortar Mixers Effectiveness

“…6) was developed at Poltava National Technical Yuri Kondratyuk University. Along with this the movable operating element of such a mixer has an external screw strap with a heightwise variable moving line [12]. This is done to increase the number of directions (componental movements or submotions) of the enforcement and inducing effects on the mixture.…”

“…This is done to increase the number of directions (componental movements or submotions) of the enforcement and inducing effects on the mixture. It is known to everybody that when the mortar mix intersects with a vertical screw elevator and a screw strap, which have a moving line, perpendicular to the axis of rotation, the mixture particles are influenced to the move in the radial direction only from the axis of rotation from any height [12]. And if in the central operating area of the screw 5 ( Fig.…”

“…In its turn, among them paddle mixers and screw mixers with horizontal configuration of agitator shafts [5,6,7,8] are used and investigated extensively, as well as paddle rotary mixing devices and planetary mixers -with the vertical arrangement of agitator shafts [9,10]. Also, particular attention should be given to vertical mixers with screw elevators [11,12], due to the fact that they have certain advantages over the aforementioned mixing plants. But it is rather difficult to determine how important the advantages of a separate type of mixer design are, how significantly they affect the final result of the workthe finished products, and how many resources have been used to achieve this result.…”
