Pan Mixer

A type of concrete mixer commonly used for batching processes, characterized by a stationary pan or drum with rotating blades or paddles that mix the materials. They are known for producing a homogeneous mix, especially for stiff or semi-dry concrete.

Types of Pan Mixer

Fixed Pan Mixers: Stationary installations for permanent batching plants.

Mobile Pan Mixers: Integrated into smaller, portable concrete batching plants or for on-site mixing.

Gear-Driven Pan Mixers: Common type with a robust gearbox.

Hydraulically Driven Pan Mixers: Offer smoother operation and finer control.

Applications in Various Industries:

Precast Concrete Production: Ideal for high-quality, consistent mixes for precast elements (blocks, pavers, pipes, railway sleepers).

Concrete Batching Plants: Central mixing unit.

Dry Mix Mortar Plants: Mixing mortar, plaster, and other dry mixes.

Refractory Material Mixing: For special high-temperature applications.

Glass Industry: Mixing raw materials.

Technology:

Planetary Mixing Action: Blades rotate around a central axis while also rotating on their own axis, ensuring thorough and homogeneous mixing.

Scrapers: Prevent material buildup on the pan walls.

Discharge Gate: Pneumatically or hydraulically operated for quick and clean discharge.

Wear-Resistant Liners: Replaceable liners on the pan bottom and side walls for extended life.

Automated Lubrication Systems: For gearbox and bearings.

Safety Interlocks: For access hatches.

Material Selection Considerations:

• Mixing Pan/Drum: High-strength steel, often with replaceable wear-resistant liners (e.g., hardox steel, high-chromium cast iron, Ni-Hard).
• Mixing Blades/Paddles: High-chromium cast iron, special wear-resistant alloys, or polyurethane (for non-abrasive materials).
• Scrapers: Wear-resistant steel or polyurethane.
• Gearbox Housing: Cast iron or fabricated steel.
• Shafts: High-tensile steel.
• Bearings: Heavy-duty spherical roller bearings or taper roller bearings.
• Frame: Robust fabricated steel structure.
