A double cone blender is a rotating drum with two cones joined to a short cylinder. It tumbles dry powder so that it folds over and mixes gently. Here you will find how the cone blender machine works, where it beats a ribbon blender and what to specify.
It is also known as a tumble powder mixer or double cone mixer.
We help you choose the machine that fits your product, batch size and plant, with specification, commissioning guidance and operator training. IPCS (Indian Paints Consulting Service) guides the selection of double cone blender, from machine specification to installation, commissioning and operator training.
Double Cone Blender overview
The drum turns slowly. Powder is lifted up the side and cascades back down, which blends free-flowing material with short mixing times and low energy. Loading and unloading are straightforward, and there are no internal ribbons, so cleaning is easy.
A double cone blender for pigment suits small to medium batches of dry colour and additive pre-blends where gentle handling matters.
Paint production applications for Double Cone Blender
Use it for free-flowing dry material and fragile particles.
Double cone blender vs ribbon blender: the double cone is gentler and easier to clean, but its batch size is smaller. The ribbon blender is better for large batches and cohesive powders.

Frequently Asked Questions
What is a double cone blender used for?
It blends dry, free-flowing powders gently, such as pigments and additives.
Double cone blender vs ribbon blender: how do I choose?
Choose the double cone for gentle blending and easy cleaning at small to medium batch sizes. Choose a ribbon blender for large batches and cohesive powders.
What is the double cone blender capacity?
It depends on the drum volume and the bulk density of the powder. Sizes run from laboratory to large production units.
Is a double cone blender good for pigment?
Yes. A double cone blender for pigment handles dry colour gently and is easy to clean between colours.
Why is it called a tumble powder mixer?
The drum rotates, so the powder tumbles and folds over itself, which blends it without ribbons or paddles.
