The W Double Cone Mixer is a type of industrial mixing equipment widely used for blending powders, granules, and other solid materials. It is designed with two conical sections that rotate, creating a smooth and uniform mixing action. This equipment is popular in industries like pharmaceuticals, chemicals, food, and cosmetics due to its gentle and efficient mixing properties.

Key Features of the W Double Cone Mixer:

1. Design and Structure:

• Double Cone Shape: The Double Cone Mixer consists of two joined cone sections that rotate around a central axis, ensuring thorough mixing by constantly moving the material.

• Symmetry: The symmetrical design ensures that all material, regardless of location, is constantly mixed for uniform results.

• Rotating Drum: The entire mixing drum rotates, eliminating the need for internal agitators or mixing blades, making it ideal for fragile or heat-sensitive materials.

2. Material of Construction:

• Stainless Steel: Commonly constructed from high-grade stainless steel (such as 304 or 316L), ensuring durability, corrosion resistance, and compliance with sanitary standards.

• Polished Surface: Both the interior and exterior surfaces are often polished to prevent material buildup and to facilitate easy cleaning.

3. Capacity:

• Range of Sizes: Available in various sizes, from small laboratory units (5-10 liters) to large industrial units (up to several thousand liters), depending on production needs.

• Loading Capacity: Typically, the effective loading volume is around 50-60% of the total capacity to allow for free movement of materials inside the cones.

4. Mixing Efficiency:

• Uniform Mixing: The double cone design ensures a homogenous mix of powders or granules due to the tumbling and cascading action created by rotation.

• Gentle Mixing Action: Ideal for mixing delicate, fragile, or light materials that may degrade or become too compacted in more aggressive mixing systems.

5. Applications:

• Pharmaceuticals: Double Cone Blender is used to blend active ingredients with excipients in tablet production.

• Food Industry: For mixing powders, spices, and other granular materials.

• Chemicals and Cosmetics: Ideal for blending chemicals, pigments, or cosmetic powders.

6. Operation:

• Rotation Speed: The W Series Double Cone Mixer typically rotates at a relatively low speed (approximately 5-20 rpm) to ensure gentle mixing without damaging the product.

• Discharge Mechanism: Equipped with a butterfly valve or similar mechanism at the bottom for easy discharge of mixed materials without segregation.

• Loading and Unloading: Material is usually loaded manually or by vacuum and unloaded by gravity.

7. Advantages:

• High Efficiency: Capable of achieving uniform blending in a relatively short period of time.

• No Heat Generation: Because there are no internal moving parts, there is minimal friction and heat generation, protecting sensitive materials.

• Easy Cleaning: The simple design without internal blades or agitators allows for easy cleaning, crucial for industries with strict hygiene requirements.

• Low Energy Consumption: The mixer consumes less energy compared to more aggressive mixers, as it relies on gravitational forces for blending.

8. Optional Features:

• Jacketed Design: Some models come with a jacketed outer shell to allow heating or cooling of the materials during mixing.

• Vacuum Sealing: Can be equipped with a vacuum feature for mixing in a sealed environment, preventing contamination or oxidation.

Applications of W Double Cone Mixers:

1. Pharmaceutical Industry: Mixing of powders for tablet formulation.

2. Food Industry: Blending ingredients such as flour, sugar, spices, and other dry ingredients.

3. Chemical Industry: Mixing of fine chemicals and granules.

4. Cosmetic Industry: Used for powders, pigments, and other ingredients in cosmetic manufacturing.
