The article presents results of research of rotary-screw
systems in relation to the creation of rotary kilns for
the annealing of-cuttings in the preparation of cement
clinker. Using the proposed design, in comparison
with known designs of similar purpose, it significantly
improves performance, reduces size and power consumption
through the use of rotary screw systems in
the form of screw rotors and drums made hollow with
sidewalls assembled from separate strips or plates of
different geometrical shapes with form inside the
screw breaks or smooth edges, screw surfaces and
screw grooves. It is shown that the housing of the rotary
kiln is expedient to produce helical surfaces whose
centers of curvature are located within the housing.
Using the proposed constructions rotary kiln during
the firing when preparing cement wedge can increase
the speed of rotation of the housing, furnaces 5-10
times due to changes in the rotary-screw systems increase
efficiency and reduce the size of furnaces
We have provided technical solutions to improve performance
of technological systems for the preparation
of solutions and concrete based on the use of screw
rotors in the form of drums with helix lines formed on
the perimeter as interconnect lines of his spiral surfaces.
We discuss the six varieties of devices and installations
for mixing, including concrete mixers, reels
which are of a complicated geometric body formed by
helical surfaces with variable or constant pitch and
which creates screw lines in the places of their connection.
In the form of screw drums, they may be conical,
concave, convex, cylindrical. The experimental test
was conducted on the concrete mixer drums, which are
arranged one in the other. The implementation of the
mixer in the form of coaxially edited two barrels provides
not only a reduction in size in length, but a significant
reduction in energy consumption due to the
use of heat, released during the activation process of
inert heating of the concrete mix as when re-mixing
and concrete mix when mixing it with water and transportation.
The drums of such systems is made of flat
elements with the formation of the helical lines discretely
spaced around the perimeter of different pitch
and with different numbers directed towards each other
helical surfaces. In the process of transporting the
components of concrete in the internal screw drum
there is active mixture of sand, gravel and cement.
Thus, there is not only the destruction of lumpy, sticky
components of the raw materials, but also active uniform
distribution of particles of cement, sand and
gravel into a homogenous mass. The implementation
of the proposed technology and equipment ensures not
only reduction of the dimensions of the mixer length,
but also improving the quality of finished products, as
well as potential cement savings of 3-5%
