Batch Mixer
Behpoo batch mixers blend dry solids and solid-liquid combinations in working volumes from tens of litres to over 30 m³. Six rotor geometries are available, selected against how your material behaves.
A batch mixer receives a pre-weighed set of components, mixes them for a defined time, and discharges the whole contents at once. Every batch is a closed, traceable event.

That is the essential difference from continuous mixing. In a continuous mixer the final ratio is the product of instantaneous feeder rates, so feeder error goes straight into the product. In a batch mixer the components are weighed before they enter, so ratio accuracy comes from the weighing system, not from the mixer.
Batch mixing is the right choice when recipes change often, when small lots need individual traceability, or when ratios are extreme.
Behpoo builds ribbon, paddle, ploughshare, conical screw, tumbler and high-shear vertical mixers, with jackets for heating or cooling, liquid injection and choppers where the process needs them. Working volume, shear level and process function are specified together.
Benefits & Features
- Working volumes from tens of litres to over 30 m³
- Six rotor geometries covering very low to very high shear
- Batch traceability — each lot is a discrete, recorded event
- Ratio accuracy determined by weighing, not by feeder drift
- Liquid injection, chopper and spray systems available
- Heating and cooling jackets
- Stainless steel and pharmaceutical-grade execution
Product Range
| Type | What it is | Typical use |
|---|---|---|
| Ribbon Blender | Horizontal shaft with two counter-acting helical ribbons | General dry blending at high volume — feed, premix, dry mortar |
| Paddle Mixer | Angled paddles on one or two horizontal shafts | Most industrial applications; shorter mixing time than ribbon |
| Ploughshare + Chopper | Plough blades throw material into a mechanically fluidised bed, choppers break lumps | Lump breaking, liquid addition, extreme ratios |
| Conical Screw (Nauta) | Orbiting inclined screw in a conical vessel | Very gentle blending of fragile materials, easy full discharge |
| Tumbler (V / Double-Cone / IBC) | The vessel itself rotates; no moving tool inside | Pharmaceutical and fragile products where no shear is acceptable |
| High-Shear Vertical | High-speed impeller in the vessel base plus side chopper | Wet granulation and coating with liquid spray |
