• Advantages and Disadvantages of V-Blender
Advantages of Using V-Blender
• Particle size reduction and attrition are minimized due to the absence of any moving blades. Hence it can be used for fragile materials
• Charging and discharging of material is easy.
• The shape of blender body results in a near complete discharge of product material, clearly an added advantage over horizontal blenders.
• The absence of shaft projection eliminates product contamination.
• V-blenders are easy to clean.
Disadvantages of V-Blender
• They require high headroom for installation and operation.
• They are not suited for blending particles of different sizes and densities which may segregate at the time of discharge.
• V-Blender with Intensifier Bar
A V-Blender can be provided with high-speed intensifier bars (or lump breakers) running through trunnions into the vessel, along with spray pipes for liquid addition. The intensifiers may be provided for disintegration of agglomerates in the charge material or those formed during wet mixing. Figure 2 is a schematic drawing of the V-Blender with the intensifier bar.
Provision of the intensifier bars makes the V-Blender adaptable for more applications. These include:
• Ability to accomplish dry as well as wet mixing.
• Suitability for mixing of fine as well as course particle compositions.
• Suitability for mixing of cohesive powders.
Provision of intensifier bars may have the following disadvantages:
• Undesired particle attrition.
• Intensifier bar shaft sealing problems.
• Cleaning problems.
