NTRODUCTION
Belt conveyors are widely used in the chemical
industry and construction materials production
enterprises. Depending on several factors such as
the size of the transported load, belt tension,
speed, and friction generated during the work
process, the belt, which is the main working part
of the conveyor, becomes unusable before the
deadline [1-4]. The moving working part (tape)
slides on the support surface that holds it, and the
fallen pieces of scattered loads transported to
these surfaces take part in the friction process
and form an abrasive environment. As a result, as
a result of the abrasive friction between the
surfaces of the tape and the support rollers, the
tape bends and microcracks appear in the tape [5-
9].

Abrasive wear, i.e., wears caused by the friction of
the transported raw material with the tape, over
time, micro-cracks cause the failure of the tapes.
Abrasiveness means that the load transported in
the work process erodes the surfaces of the
equipment in contact with it [10-14].

Loads are divided into 4 groups according to the
level of abrasiveness: A - non-abrasive, V - low
abrasive, C - medium abrasive, and D - high
abrasive. Coke, coke, agglomerate, and recycled
agglomerate are highly abrasive. Quartz sand,
ferrous and non-ferrous metal ores and their
concentrates have low abrasiveness. The
presence of large links of limestone in
agglomerate is a factor determining its chemical
aggressiveness. In conveyors transporting such
loads, roller supports and metal structures wear
significantly faster [13-15]. The moisture content
of 4-6% of cargo reduces dust generation during
transportation. Increased humidity reduces the
spreadability of the load and clogs the funnel part
of the loaders. The stability of the load is
characterized by the coefficient of stability.

compression load, (MPa).
Clumping is the loss of mobility of loose (clay, salt,
cement) loads during long-term storage.
Viscosity is the ability to change loose loads (clay,
boron) into solids (especially in wet conditions).
A description of the most common scattered loads
is given in Appendix 1.
Currently, the production enterprise, the method
of connecting with rivets is used in the repair of
bent or broken tapes.

Figure 1. Rivet nail method
In this method, the connecting parts of the tape
are fastened to each other with superimposed
rods. This causes raw materials to spill as a result
of shaking of the tape when the rivet nails collide
with the roller and drum surfaces when the
conveyor moves, and accelerates the bending of
the rivet nail, rollers and drum surfaces. As a
result, the service life of the conveyor is reduced.
In order to increase the service life of belt
conveyors and other working parts that wear out
due to friction, it is advisable to use the method of
restoring broken tapes.
As a result of vulcanization, it is glued with raw
rubber layer by layer after heating. It is cut and
prepared as shown in Fig.

The two ends of the connecting tape and the two
ends of the patch tape are cut in accordance with
each other as shown in the picture. Each surface
is vulcanized with specially produced adhesives
for patching cord materials.
The tape repaired in this way increases the life of
the tape, and also increases the life of the rollers
and drums.
Belt conveyors require constant monitoring of
belt tension and working conditions, with
particular attention to belt connections.
In order to ensure the long-term operation of the
tape, it is necessary to ensure the following:
a)
load the transported goods only after the
movement of the tape is stabilized;
b)
stop the transported cargo only after it is
completely filled with tape material;
c)
elimination of the possibility of mineral
oils entering the tape;
d)
to monitor the wear of the rubber tape
passing through the load-cleaning shovels (the
tape is not squeezed by the shovels with a metal
div);
e)
timely replacement of non-rotating
support rollers;
f)
making timely decisions to prevent the
tape from moving to different sides during
movement.
The movement of the tape in different directions
is caused by factors such as skewing of the
tensioning drum, installation in the wrong
position or the error of locking in relation to the
central axis, the incorrect connection of the ends
of the tape, the appearance of separations in the
seams and layers of the tape along one side of the
drum.
C
ONCLUSION
As a temporary measure to prevent the tape from
moving in different directions, it is recommended
to install several support rollers on the wrong
side of the tape that deviates from its direction.
Usually, self-aligning support rollers in such
transport devices are the means to eliminate the
errors of the transverse movement of the tape.
