foundation frame.

Each component has a different composition and
structure, and in addition, the production of tires
is very complex and expensive. The tire is based
on the following basic principles [5-12]:

high quality rubber;

use of quality fabrics for the cord;

reliable steel frame;

plastic assembly technology;

high quality vulcanization;

Comprehensive quality control.

Thus, the following scheme is used in the
production of tires, including three stages:
processing, preparation and production of raw
materials [13-24].

In the raw material processing stage, the rubber
mixture is mixed in a closed rubber mixer. The
whole process takes place under pressure and at
high temperature in automatic mode.

Figure 1. Scheme of tire raw material processing process

In the extruder (syringe or screw press), each
component of the tire is formed in the form of
tape (tread, side walls and other elements). At
this stage, recycled compounds are also used in
the formation of the mixture, and the rubber
mixture is plasticized separately, and only then
are they mixed [25-37]. Reconstituted mixtures
are much easier to inject because they have less
shrinkage and retain their shape and size better.
However, the speed of the process is high and
energy costs are high. In parallel with mixing,
other technological positions produce textile tires

carcass, bead cores and cutters. The textile fibre
is wrapped in a cord and inserted into a calendar,
where it is lubricated with a thin layer of rubber
on both sides using a complex and expensive
method [38-46]. There are 2 types of calendars
for rubberizing fabrics: friction, in which the
rubber mixture is applied to the fabric due to
friction between the rolls; Rubber mixture is
applied to the lining fabric in the form of a thin
layer and passed through rolls. Calendars also
apply a layer of airtight rubber to the tireless
tires.

Rubber is also applied to steel wire in a complex
way. It should be borne in mind here that the
decisive factors are the minimum oscillations in
the thickness of the rubber layer to which the
rubber is applied, and secondly, that the rubber
must be connected to the wires. The textile fibre
is cut into strips of any length and the steel is cut
along a similar width and wrapped around the
drum in the form of a rigid ribbon. The side ring is

also equipped with a rubber shell [47-52]. All
components are fed to a collection drum that has
the shape of a cylindrical inflatable roller. The two
sides approach from the side, then the wire is
pulled into the frame, after which the flat
structure acquires its final toroidal shape [48-55].
The solid layers are supplied with compressed
air.

Figure 2. Schematic of the tire production process

The semi-finished product is pressed into the
mold during heating for 9-17 minutes at a
pressure of 12-24 atmospheres and 165-

200 ℃.

Thus, all manufactured car tires can be divided
into radial location of the frame - radial and
diagonal - diagonal tires. Radial tires use steel
wire with a diameter of 0.2 mm as a material for
cord and carcass threads. These types of tires are
used in both cars and trucks and buses. Diagonal
tires use materials such as textiles, nylon,
polyester and more. These types of tires are
mainly used in low-speed vehicles. Therefore, the
process of separating the above Ash types into

separate components should be done differently.
As mentioned above, the ash separation process
should be performed according to the following
algorithm

washing;

heat treatment;

extraction of the inner ring by means of an
extractor;

tread release;

separation of wire and frame layers (for radial
tires);

grinding (rubbering) of rubber components;

assembly and packaging of the finished
product.

Therefore, the method of conducting the
experiment will have the following sequence.

1.

Car tires from leading factories of the

world and Russian manufacturers were selected
as samples for the experiment: Michelin,
Goodyear, Continental, Bridgestone, Kama,
Medved.

2.

Pre-selected ash is washed using washing

equipment.

3.

All of the above prepared tires are heated

in a temperature range of 120 to 300 ° C. For each
ash, the actions required to break it down into
components are determined. Mathematical
dependencies were built.

4.

Efforts to obtain a Cord Ring and Bracket

were identified and mathematical dependencies
were constructed.

5.

Disassembly of car tires.

6.

Grinding of rubber parts of ASH was

carried out by means of an abrasive grinder with
abrasive grains of different sizes in a full-size
installation. Experimentally determined:

feeding power, H;

linear cutting tool speed, cm / min;

amount of feed, mm;

7.

The dimensions (dust) of the obtained

rubber chips are measured.

8.

The process of obtaining rubber powder is

optimized.
