S210 continuous sand mixer

Double-arm sand mixer with a capacity of 3-10 tons per hour and the 3 meters second arm. The second arm allows to enhance service zone substantially and to feed mixture to desired position that simplifies large molds forming.
The mixer is intended for preparation of cold binder-bonded mixtures during molds and cores production.

Litmashpribor LLC offers S210 continuous high-speed double-arm sand mixers with screw sand feeding in the first arm for your enterprises.

The mixer is intended for preparation of cold binder-bonded mixtures during molds and cores production. Sand mixers of this design enable facilitating of manufacturing of large molds due to the possibility of the finished mixture to any point of the mold.

Field of application:

The mixer can be used in foundry workshops of individual small-scale and serial production using the Alpha-set and Furan-processes.


  • Operating reliability
  • Ease of maintenance
  • High capacity
  • Elegant design
  • Large operating radius
  • Equipment capacity from 3 to 35 tons per hour
  • The equipment has the ability to change the capacity and change the mixture composition.
  • Example: 1) 5.2 t/h — 100 % of fresh quartz sand, 1.6 % binder (of sand)/21 % of solidifying agent 2) 6.1 t/h — 100 % of fresh quartz sand 1.4 % binder/21 % of solidifying agent 3) 9.4 t/h — 30 % of fresh quartz sand, 70 % of reclaimed sand, 1.6 % binder/21 % of solidifying agent 0.1 % of water 4) 7.8 t/h — 15 % of fresh quartz sand, 85 % of reclaimed sand, 1.6 % of binder/21 % of solidifying agent and 0.1 % of water
  • Number of programs can be increased according to customer requirements
Product design:

The mixer design provides for two tube mixing troughs made of wear-resistant 8 mm thick steel and a high-speed rotating screw. The operation principle of the mixer is rapid mixing of the sand with the liquid components fed into the tube mixing trough of the second arm and the discharge of the finished mixture into the mold from the tube mixing trough. The integration of mixing beaters made of wear-resistant steel enables to reach the maximum service life with used bonding components minimum flow-rate.
