What Is a Double-Screw Conical Mixer?
A double-screw conical mixer is a vertical batch mixer that moves material within a cone-shaped vessel. In the DSH arrangement, two asymmetric screws create repeated powder movement through the batch. This design is used to evaluate mixing duties involving powdered ingredients with differing physical characteristics.
How Does It Work?
The screws rotate while moving through the conical vessel. Material is lifted from the lower region, redistributed and allowed to fall back under gravity. This repeated circulation supports mixing throughout the batch. The required mixing time and final uniformity depend on the actual formulation, fill level and machine configuration.
DSH Model Specifications
| Model | Total vessel volume (m³) | Loading coefficient | Reference batch output at ρ = 1 g/cm³ (kg) | Motor power (kW) | Mixing time (min) | Machine weight (kg) |
|---|---|---|---|---|---|---|
| DSH0.3 | 0.3 | 0.4–0.6 | 180 | 2.2 | 4–10 | 500 |
| DSH0.5 | 0.5 | 0.4–0.6 | 300 | 2.2 | 4–10 | 1,000 |
| DSH1 | 1 | 0.4–0.6 | 600 | 5.5 | 4–10 | 1,200 |
| DSH2 | 2 | 0.4–0.6 | 1,200 | 5.5 | 4–10 | 1,500 |
| DSH4 | 4 | 0.4–0.6 | 2,400 | 11 | 4–10 | 2,800 |
| DSH6 | 6 | 0.4–0.6 | 3,600 | 20.7 | 4–10 | 3,500 |
| DSH10 | 10 | 0.4–0.6 | 6,000 | 30.7 | 4–10 | 4,500 |
Additional conditions in the published reference: mixed-particle size 40–3000 μm; ambient temperature and pressure; dust-tight operation. The listed batch outputs assume material density of 1 g/cm³ and the upper reference loading coefficient of 0.6. Special materials require evaluation. Mixing time is a reference value, not a guaranteed result for every recipe.
How to Read Mixer Capacity Correctly
A mixer’s total vessel volume is not the same as its usable batch volume. The powder occupies only part of the vessel so it has room to circulate. Batch weight also changes with the material’s bulk density.
Illustrative sizing example:
- 1 Target batch: 300 kg
- 2 Measured bulk density: 600 kg/m³
- 3 Occupied powder volume: 300 ÷ 600 = 0.50 m³
- 4 At an illustrative 0.60 working fill, theoretical vessel volume: 0.50 ÷ 0.60 ≈ 0.83 m³
Note: This calculation explains preliminary sizing. It does not identify a confirmed JEXDRY model or guarantee a fill level for the material. The reference table’s batch outputs are based on 1 g/cm³ and specific conditions; do not apply those kg values universally.
What Should the Mixer Solve in Your Process?
Reviewing the right design factors ensures the equipment matches your actual working conditions.
1. Ingredients with different bulk densities or formulation ratios
A recipe with contrasting ingredients needs material movement across the batch. Review whether the DSH circulation pattern suits the actual powder and desired blend result.
2. An uncertain batch-size calculation
Kilograms alone do not determine vessel size. Measure bulk density and define usable fill before comparing model numbers.
3. Cleaning and discharge constraints
Blend quality is only one part of the decision. Confirm the feed route, outlet, dust control, cleaning access and connection to downstream equipment.
Why Consider a DSH Double-Screw Arrangement?
Two screws moving through a conical vessel provide repeated lifting and redistribution of powder. The arrangement is relevant when engineers need to examine how ingredients with different physical characteristics move through the batch.
The vertical vessel and bottom discharge also make the equipment interface an important part of specification review. The appropriate configuration depends on material behavior, cleaning requirements, plant height and the required mixing outcome.

Bottom Discharge

Typical Materials for a Conical Screw Mixer
Drawing on our experience in industrial powder processing, we consider conical screw mixers for blending food ingredients, pharmaceutical excipients, chemical and mineral powders, and feed premixes. The materials below are typical applications we review when selecting a configuration for a specific batch.
Food Ingredients
Food powders can differ in particle size, flow behavior and sensitivity to handling. Review the recipe, ingredient ratio, cleaning requirements and required product condition before selecting the mixer’s contact materials and configuration.
Pharmaceutical Excipients
For excipient blending, define the ingredient ratio, required blend assessment, cleaning approach and product-contact construction. A pharmaceutical application does not by itself establish that a proposed DSH configuration meets a particular hygiene or regulatory requirement.
Chemicals & Minerals
These materials may have very different bulk densities, particle characteristics and handling requirements. Review dust containment, wear, cleanability and the target blend before confirming a specification.
Feed & Nutritional Powders
When a formula combines ingredients in different proportions, confirm the batch size, bulk density and required distribution of minor ingredients. The suitable mixing cycle and final result must be assessed for the actual formulation.
Single Screw vs Double Screw vs Ribbon Blender
Comparing common mixing technologies for bulk powders.
Single-screw conical mixer
One screw lifts and circulates material in a conical vessel. Its suitability depends on the specific design, powder properties and batch duty.
DSH double-screw conical mixer
Two asymmetric screws move through the cone. We highly recommend this double-screw configuration for its superior mixing efficiency, precision, and versatility. Request confirmed specifications for your proposed equipment.
Horizontal ribbon blender
Inner and outer ribbons move powder within a horizontal trough. It is a separate mixing route for suitable materials.

Conical Screw Mixer Questions, Answered
What is a conical screw mixer?
A conical screw mixer is a batch mixer that circulates material inside a cone-shaped vessel using one or more screws. This page focuses on the DSH double-screw arrangement.
How does a double-screw conical mixer work?
The screws lift material from the lower part of the cone and redistribute it through the batch. Powder falls back under gravity, creating repeated circulation.
How does it work in industrial powder processing?
Powder is charged, mixed toward a defined target and discharged to the next process. The feed, dust control, cleaning and outlet connections must suit the surrounding line.
Is single screw or double screw better?
Neither is universally better. Compare powder behavior, material movement, batch size, cleaning access, power and the required result. JEXDRY’s documented DSH family is the double-screw type.
Where can I buy a conical screw mixer suited to my material?
Ask a supplier to review the powder properties, target batch and plant interface, then provide a model-specific proposal. JEXDRY can discuss the DSH family listed in its catalog; the final configuration must be confirmed for the project.
How should I compare conical screw mixer manufacturers?
Compare specifications under the same assumptions: vessel and working volume, powder bulk density, calculated batch output, motor power, materials, sealing, discharge, dimensions and the method used to assess the blend. A generic “best manufacturer” list cannot replace this technical comparison.
