PerMix Conical Mixer

Agitator & Motion

• Conical vessel houses a spiral screw (or dual/triple screws) that rotates on its axis while orbiting (“planetary motion”) near the conical wall. This drives upward lifting, after which material falls under gravity, producing axial-radial mixing.
• Multi-screw options increase mixing intensity where needed without aggressive shear.

Sealing & Containment

• All sealing systems are placed outside the material zone, preventing lubricant or sealant contact with the product.
• Solutions include mechanical double seals, Cinchseal, packing seals with purge, or gas-sealed designs — selected for ATEX or inerting environments.

Thermal Control & Vacuum Options

• Vessels can be fitted with heating/cooling jackets (e.g., steam, thermal oil, water) for temperature regulation during mixing or drying.
• Vacuum / deaeration features may be integrated — especially useful if moisture control or degassing is required.
• For vacuum drying, moisture is drawn off at lower temperatures, preserving thermal-sensitive materials.

Feeding & Discharge

• Powder feed can be via gravity feed, vacuum transfer, or side/top ports.
• Spray nozzles allow precise liquid or binder addition during mixing.
• Discharge options: bottom valves (semi-ball, butterfly, slide), tilting vessels, or external conveyance.
• Designs aim for minimal residuals and quick, clean discharge.

1. Loading — powders or granules enter the conical vessel, often under controlled feed conditions.
2. Agitation Phase — the screw(s) lift material up the wall; material cascades down, promoting mixing.
3. Binder / Liquid Addition — spray injection systems introduce precise liquid binders or solvents while mixing continues.
4. Vacuum / Drying (if equipped) — vapour removal under vacuum, aided by jacketed surfaces.
5. Discharge — material releases cleanly, with design aiming for <1% retention.

Because motion is gentle, this is ideal for fragile or shear-sensitive compounds (e.g. fine APIs, flavour encapsulates, cosmetic powders).

• Single, double or triple screw designs for flexibility in mixing profile
• Variable speed drives (geared motor, cycloidal or worm reducer, belt or chain)
• Material choices: 304 / 316L stainless steel as base, with optional Hastelloy, Duplex, Titanium, etc
• Finishing & surface treatments: food-grade 180-grit polish, mirror polish, electropolishing
• Heating / cooling jacket designs (shell-and-tube, dimple, half-pipe coil)
• Vacuum & purge integration
• High-speed choppers / breaker blades for lumps or agglomerates
• Instrumentation & control: pressure, vacuum, temperature probes, PLC/HMI, recipe control
• Explosion-proof builds / ATEX compliance
• Sampling ports, inspection windows, CIP access

PerMix conical mixers are well-suited to:

• Pharmaceuticals / Nutraceuticals: blending of active ingredients, excipients, or moisture-sensitive powders
• Food & Beverage: flavour premixes, seasoning blends, delicate additive powders
• Cosmetics & Personal Care: fine powders, fragrance coatings, pigment blends
• Specialty Chemicals: pigment mixing, catalysts, additives requiring gentle handling
• Fine Chemicals / Lab-scale scaling: small batches with scale-up to production

Example: In a UK pharma plant, a conical mixer with vacuum drying is used to blend an API with excipients, then gently dry in situ before transfer to coating — all in a closed system.

• Product Integrity: Gentle motion preserves particle shape, avoids attrition
• Low Contamination Risk: No internal seals, lubricants isolated
• Small Footprint & Adaptability: Works well across range of batch sizes
• Energy Efficiency: Vacuum draws moisture at lower thermal burden
• Ease of Cleaning / Validation: Minimal crevices, fast discharge, CIP readiness
• Regulatory Conformity: Build options for UKCA, CE, GMP, ATEX
• Local Support: Commissioning, spares, service & documentation from UK team

When choosing, evaluate:

• Required batch volume / throughput
• Product properties: friability, shear sensitivity, particle size
• Need for moisture control, vacuum, or degassing
• Thermal control demands (heating / cooling)
• Materials compatibility (corrosive, sensitive compounds)
• Cleanability, ease of validation, CIP / GMP constraints
• Discharge design and integration with downstream systems

PerMix UK engineers can guide you through matching your process parameters to a fully specified conical mixer.

If your process requires gentle, precise mixing with optional drying in a compact, regulatory-friendly system — a conical auger mixer is often the optimal choice.

Performance Born from Engineering Excellence

DP Pulverizers designs and builds mills that transform production efficiency. Every model is developed using computational airflow analysis, high-tolerance machining, and precision balancing, ensuring micron-accurate results and continuous uptime.

Our systems are built from stainless steel, Hardox, or alloy steels to suit your application — whether it’s fine sugar powders, conductive graphite, or cryogenically ground polymers. Each design meets ATEX, GMP, and CE standards, ready for industrial and pharmaceutical environments across Europe.

Our Range of Milling Solutions

Pin Mills
Delivering fine, consistent particle reduction for spices, starches, and chemical powders with high energy efficiency and minimal heat generation.

Turbo Mills
Engineered for high-speed micronizing of plastics, pigments, and resins, turbo mills use controlled turbulence for fine results without overheating.

Hammer Mills
The robust, heavy-duty solution for bulk grinding and granulation in food, minerals, and biomass processing. Available in Hardox for abrasive products.

Jet Mills
Utilizing compressed air rather than moving parts, jet mills achieve sub-5-micron fineness ideal for pharmaceutical and nano-material production.

Cryogenic Mills
Low-temperature milling using liquid nitrogen keeps materials stable, preventing softening or clumping — essential for elastomers, thermoplastics, and fine foods.

Universal Mills
A versatile platform that adapts to pin, hammer, or turbo configurations, perfect for manufacturers handling multiple product types on one line.

Cone Mills (Comils)
For gentle deagglomeration and uniform sizing, cone mills are a clean, quiet option for final powder conditioning and pre-mix applications.
