Continuous Mixers

The developments of UE "INSTITUTE BELNIILIT" include a series of continuous mixers for preparation of sand-resin mixtures with output 1 to 6 tons/hour.

    Double-screw mixer of continuous action S2SH1 consists of chamber of prior mixing which includes mixing unit with drive, chamber of final mixing (whirling head), device for sand delivery with flow separator, two slide shutters with pneumatic cylinders, three plants of taking and batching of fluid components.
    Delivery of fluid components in screw hoses is carried out by batching pumps of ND type. Flows of sand move with binding component in one hose, and with curing agent in the second hose. They advance through  the screws to discharging aperture and come to the chamber of final mixing (whirling head), where the flows are mixed by vertically revolving blades till the mix becomes ready for use. From whirling head the mix goes to a core box or flask and may be compacted on the vibrating table if necessary.
 
S1SH3    High-speed single-screw mixers mod. S1SH3 is characterized by simple design and reliability. Mixer design provides one screw chamber with one high-speed screw. Principle of operation of the mixer consists in fast mixing of sand with fluid components delivered to the screw chamber and discharging prepared mixture from screw chamber into a mold. Mixing of  mixture components and discharging of prepared  mixture is carried out by blades fixed on shaft of short screw. Comparatively short chamber of screw and high speed of screw rotation provide an opportunity of fast and whole discharging of core mixture from mixer at the end of each operating cycle. Such a kind of design provide high level of mixing of core mixture components according to up-to-date technologies.
 
    The mixers can be equipped with vibrating table mod. 4767. Technical characteristics are shown in the table below:
