Dredge

The history of dredging in modern Russia began in the workshops of the Irkutsk Heavy Machinery Plant named after V.V.Kuibyshev, so in 1930 the first wooden dredge on pore engines with a bucket capacity of 150 liters was created.
However, modern designs of all-metal dredges on electric motors were developed and delivered after the Second World War:
In 1947, the IZTM team designed and built a 150–liter all-metal electric dredge. Its productivity reached 100 m3/hour.
In 1950, a 210-liter dredge was made.
In 1956, the plant produced a block-welded all–metal electric dredge with a 250-liter scoop.

The construction of new high-capacity dredge aggregates is a very expensive enterprise, therefore the supply of new dredges is currently limited, and modernization of already operated dredges prevails, as well as their relocation to new deposits in case of economic feasibility. Basically, processing equipment is undergoing modernization, which adapts to the conditions of new deposits, as well as dredges are equipped with modern electric motors, automation and telemetry systems.

Such a long period of productive operation of drazhny units requires an established supply of spare parts. The company LLC "OrMag" has mastered the production of spare parts and is ready for mutually beneficial cooperation.

On dredges that operate using shore blocks (the rope of the bow winch is attached to the scoop frame through the shore block), productivity is often increased by increasing the voltage of the engines of the bow winches above the nominal, which can lead to a reduction in the service life of the parts of the shore block. In the catalog of LLC "OrMag" the presented parts and blocks are assembled, available for custom manufacturing. The composition of the dredge processing equipment includes: a drum screen (dredge barrel); sluices for catching precious metals with transverse and longitudinal troughs; a jigging machine. The catalog of LLC "OrMag" contains an extensive range of lining products to extend the service life of the surfaces of draught barrels subject to wear, as well as various sowing surfaces, grinding plates, gears for drive shafts.

It is also possible to manufacture custom-made spare parts for lifting and lifting devices of dredges. The company LLC "OrMag" designed and produced specialized thin-walled wearable water pipes for hydrothawing systems of frozen rocks, in the fields of draught extraction. The designed water pipes can also be used for other water supply systems necessary for mining.
