Double Cone Blender

The Double Cone Blender works through controlled vessel rotation and repeated particle movement. Its two cones are joined at a common central section, producing a changing orientation of the powder bed as the chamber turns. The mixing action is predominantly tumbling and cascading, rather than the intensive shearing used in some other mixing systems.

Material Charging

Dry powders or granules are charged through the designated opening. The practical batch charge is selected according to material bulk density, free volume and the required blending result rather than assuming the entire gross volume can be filled.

Setting the Blend Cycle

The operator sets the rotation conditions and mixing period appropriate to the formulation. The drive and worm-reduction gearbox rotate the vessel at the selected speed; the loading arrangement and guarding are checked before the cycle begins.

Tumbling and Intermixing

As the cones turn, material repeatedly moves between the conical sections. This cascading action redistributes individual components throughout the batch. Internal fixed baffles, where supplied, assist circulation and blending.

Positioning and Discharge

At the end of the cycle, rotation is stopped and the vessel is positioned for unloading, with manual hand-wheel inching available where specified. Product exits through the designated discharge arrangement, including a butterfly valve on applicable sizes.

Cleaning and Changeover

After the batch has been discharged, the charging opening, discharge valve, product-contact surfaces and gaskets are cleaned under the plant's procedure before the next product or formulation.
