Design, Working And Advantages Of A Double Cone Blender

In the production of products for the healthcare, food, chemical, cosmetics, detergents, fertilizers, and plastics industries, mixing is a typical manufacturing step. The double cone blender is used to create a homogenous solid-solid mixture that is uniform inconsistency.

 

The Double Cone Blender's Working Principle

In the dry blending of free solids, double cone blenders are the most commonly utilized type of mixer. They are capable of blending a wide range of solids with varying bulk densities and percentages of the overall mixture. With each rotation of the double cone, the stuff being blended is constantly intermixed. It is common for the cycle time to be 10 minutes, although it might be longer or shorter depending on how complicated the item being mixed is.

 

The Design and Construction of a Double Cone Blender

Its primary body is composed of two cone-shaped parts that are welded together at their bases to form a cylindrical section in the center of the machine. During rotation, the axis of rotation is perpendicular to the axis of the cone and passes through its cylindrical part. The drive motor is housed within one of the two lateral supports that hold the blender body in place on the table. Stainless steel is used in the construction of the double cone blender. This is completely mirror polished on both the inner and outside surfaces. Ball bearings are used to support the unit, which is mounted on mild steel or stainless steel stand. The conical shape at both ends allows for homogeneous mixing and discharge while still being lightweight. The cone is statically balanced, which saves the gearbox and motor from being subjected to an excessive amount of pressure.

There is a butterfly valve of the proper diameter at one end of the cone to allow for material discharge, while openings with removable covers are provided at the other ends of the cone for material insertion and cleaning. Inside the blender, there are stainless steel baffles that serve as the driving arrangement, which is powered by a motor through a reduction gearbox. It has the capability of operating at a variable speed. For larger models, optional features such as a safety barrier, a limit switch, and a platform are available. Associated provisions include the ability to include a liquid spray system into the process in order to introduce liquids in spray form throughout the process. 

A vacuum device with self-cleaning hoses can be used to introduce powders and granules into the blender body, automating the loading process. In addition to a product receiving hopper with an automated self-cleaning filter, the device is outfitted with a control panel. A retractable hermetic bellows system that is pneumatically operated can be used to load and discharge the container.

 

The Operation of a Double Cone Blender

Intake systems for powdery or granular materials are used to feed materials into the double cone containers, while hand-feeding is also used. The material moves in a complicated and vigorous manner due to the constant rotation of the containers, resulting in a homogeneous mixing. The conical shape at both ends aids in consistent mixing as well as a simple release of the product. Depending on the material's characteristics, paddle-type baffles can be installed on the shaft to improve mixing, consistent blending, and de-agglomeration while the material is being processed. A dust-free bin charging method ensures that only the bare minimum of material is handled. The solids are loaded into the blender through the loading hole on the side of the machine. The mixing occurs axially as a result of the movement of the powder bed across the various parts. The mixing is comprehensive, but the speed at which it occurs is dependent on the rotational speed. When the mixture is discharged, it is done so through a hermetically shutting butterfly valve that can be handled manually or by computer.

 

Advantages

1.      With its closed container, the cone blender provides good product rolling and cross mixing.

2.      The conical shape at both ends and ‘Slant' design allows for homogeneous mixing and easy discharge.

3.      It mixes, blends uniformly, and de-agglomerates.

4.      The cone is statically balanced, which protects the gearbox and motor from being subjected to an excessive amount of stress.

5.      There are two different openings for feeding and discharging powder.

6.      If necessary, paddle-type baffles can be installed on the shaft to improve mixing performance depending on the product's characteristics.

7.      Contact parts are made of stainless steel, which helps to avoid corrosion and product contamination. In order to ensure minimal material handling, it features a dust-free bin charging mechanism in place.

8.      Additional elements such as a spray system, a loading system, a receiving hopper, and flame-proof electrical connectors can be added.

 

The Double Cone Blender has a variety of uses.

1.      When it comes to tablet and capsule formulations, dry powder and granules are quite useful, and the cone blender is one of the most versatile tools available.

2.      In the bulk lubrication stage of tablet granule production, it is utilized for dry granule sublot mixing to enhance batch size.

3.      It has the potential to be used for the dry powder to wet mixing applications as well.

4.      It can be utilized in a variety of industries including medicinal, food, chemical, and cosmetic industries.

5.      High mixing quality is achieved by using this device for mixing highly flowable powdered and granular materials with exceptional mixing quality.

6.      It can be used for material mixing in the food, essence, dye, chemical, plastic, and rubber industries, among other things.

7.      It can be used for medical intermediates, flavoring, graphite, coffee powder, and iron powder, among other things.
