mixer rotors operate in harsh conditions and are subject to heavy wear. They shall be regularly checked and worn surfaces should be restored by welding. It is necessary to continuously monitor devices for sealing the rotor nodes neck passage through the mixing chamber wall, or as the friction gland seals do not tolerate a high pressure in the chamber, they wear out and need frequent cleaning and restoration. It is better to provide a sealed chamber dvuhla-birintnye or trehlabirintnye seal threaded groove located in the direction opposite to the rotation of the rotor.
perform specialized works on repair of rubber mixing line, production mixer rotors, rotor repair, welding, alignment, repair or complete production of new rotors, balancing, manufacturing and replacement of the labyrinth seals of the rotors. We produce blades recovery, recovery shelves, tires, replacement of liners from the hard ridge.

- Castings for spare parts and rotors tointernal rubber mixers RS-270, 250, 90, 71, RSVD-140are made according to new European cast technology -using forms out of coldconsolidating mixtures (CCM), which enables to gain cast precision class 8-13 , in complex geometry forms with precision 1 mm., high quality of surface smoothness and low grade of casting defects. Forms and pins are made at forming line of preparing self-hardening mixtures by OMEGA company (England) according to cold-box furan process technology. Starting material as well as finished products are subjects to laboratory testing (via spectrometer SOLARIS CCD Plus, Italy) which secures obtaining of moulds with one-to-one correspondence of targeted microstructural and chemical composition of product.
- We also supply assembly units as well as spare parts to enterprises of such spheres: rubber technical industry, cable manufacturers, tires manufacturers, asbestos technological companies, hydropower plants, heat and power stations, mining and processing complexes. Utilization of manufactured equipment in chemical, petrochemical, metallurgical, mining and ore mining, oil and gas extraction, building and many other industry fields.
