Twin screw paddle conditioners for dampening, neutralising or stabilising fly ash and similar residual bulk solids

AJAX Twin Screw Continuous Mixers for Conditioning Powders.

AJAX conditioners produce a high quality mix combining fine dry powders like fly ash with water or other liquids because of the efficient multiple and progressive actions of intermeshing paddle screws. Homogeneity is quickly achieved and the effective work input means relatively low energy requirements. . Conditioning means that environmental concerns over dusty offloading can be countered and in some applications neutralising of two waste streams carried out simultaneously e.g. alkaline ash and acidic liquor can be effectively combined. Spray bars can be incorporated in the unit even along the full length or within pitched covers and these can be opened ended sparge pipes or fitted with spray nozzles. Product transfer is concurrent with the mixing process so segregation and quality issues associated with intermediate storage and separate, sequential operations can be avoided. Reduced handling and mix quality are built in. Easy cleaning of the machine internals is often provided with even large machines having easy to operate counterbalanced covers which provide full access for powder washing internals. A range of safety switch choices form proximity type through to captive key can be accommodated. AJAX conditioners have been proven to handle a wide range of dusts and positively combine solids with liquid that differ in flow properties, size and bulk density.

Features Include:

• Blending and medium shear mixing of wet or dry multiple ingredients.


• Efficient mixing with gentle handling of delicate ingredients.


• Single and twin screw versions in a wide range of capacities.


• LynFlow^TM Paddles for sticky and difficult to mix ingredients.
