The sand mixer is designed for the preparation of cold-hardening mixtures for the production of medium and large molds. This type of mixer is most often used in conjunction with flat or roller vibrating tables as part of automated molding lines or as a free-standing molding section. Thanks to the block design, the mixer has many modifications that allow it to adapt to any technological process and satisfy any customer's wishes.
The main possible modifications:
Optional hardener pump - allows fast and slow hardener to be used without interruption
Additional water pump - the possibility of increasing the moisture content of the reclaimed sand
Flowmeters for chemicals - the ability to adjust the survivability of the mixture over a wide range
Aspiration of the unloading area - improving the working conditions of the operator
Low sand sensor - informing and protecting equipment from working without sand
Dispenser for bulk additives - the ability to use bulk modifiers of the mixture
Systems included in the basic delivery:
Replaceable carbide tipped blades
Control and configuration by industrial controller and operator panel
Sand batcher with 4 flaps
Frequency controlled high precision metering pumps

High performance
Possibility of flexible adjustment of the composition of the mixture according to the productivity and the amount of binders
Product design:
The mixer design provides for the presence of one auger chamber with a high-speed rotating auger.
The principle of operation of the mixer is to quickly mix the sand with the liquid components supplied to the screw chamber and unload the finished mixture into a mold.
The arrangement of mixing blades, made of wear-resistant steels with the use of tungsten carbide plates, allows to achieve the maximum service life with the lowest possible indicators for the consumption of the used binders.
