In order to provide denser piling of raw materials into the retort the tires can be cut, however with the more dense piling the process becomes longer. For example when loading 0,5 t of tires the cycle makes 10-11 hours, and while loading 0,8 t of tires the cycle makes 16 hours. Tire cutting process is illustrated on the video and goes according to the following algorithm: at first tire bead is cut and then the tire is carved with the help of special scissors for tire cutting. Whole or cut pieces of tires are loaded into retort (basket) after that the retort is put into the pyrolysis installation (reactor) with the help of telpher or other lifting mechanism. There it is heated up to 500 °C with no access of oxygen (pyrolysis process).

Initially the installation is heated with the help of additional fuel; home-made products (carbon residue (semi-coke), liquid fuel fraction, pyrolysis gas (methane)) can be used for this purpose. After the 2-3 hour mode is achieved additional fuel is not used, the gas jet, working on non-condensed residues of pyrolysis products, is activated instead. In the result of the pyrolysis process gas and steam mixture is obtained. The mixture is directed into the condensation system (rectifying column). After rectification the residues of gas and steam mixture are burned down in liquid fuel gas jet which ensures the process maintenance. As a result of condensation liquid fuel fraction called synoil is obtained.

As the pyrolysis process is exothermal reaction followed by heat release, extra pyrolysis gas similar to methane is obtained. It can also be used profitably. The duration of the process makes 10-11 hours taking into account that 0,5 t of tires are loaded into the retort. When the process is over which is indicated by the control and measuring apparatus and by termination of gas emission, the pyrolysis installation is opened with the help of telpher and the retort is taken out, sealed and moved to cool down.
In its turn another retort with raw materials is loaded into the vacant pyrolysis installation after that the process continues. The set for one unit of the installation includes 2 retorts; it allows using the installation continuously.

After the full cooling action (10-12 hours) carbon residue and metal cord can be mover from the retort. Then metal cord should be separated from carbon residue. It is possible to use the mechanized way of separation. In order to do this the contents of the retort are loaded into a cellular basket which is installed into the sieving machine, where the separation of carbon from metal cord takes place. Fine pieces of metal are removed with the help of magnet separation. After sieving machine we obtain clean metal cord and also black carbon ready for the further processing.
In order to make the usage more convenient and to ensure continuous production process the set of one reactor includes two retorts.
