V Blenders :
V Blender designs are most often used for the intimate dry blending of free-flowing solids. The solids blended in these units can vary in bulk density and percentage of the total mixture. Materials are combined and frequently split and intermixed as the shell rotates. Standard cycle times are typically in the range of 15 minutes. However, they can be less depending on the difficulty of blending.
V Blenders stocks are available in 5, 10, and 15 cu. ft. capacity. Each is constructed of type 316-stainless steel and is internally polished to a 240 grit sanitary finish. The polished exterior helps to clean a 150-grit finish quickly.
V Blender machine or v cone blender is supplied with Intensifier bars to permit deagglomeration as needed. Discharge through a manually operated Butterfly valve. The valve is positioned 24” from the floor when in the bottom position. All units are provided with appropriate safety railings and appropriately interlocked safety interlocks, including Stop-Start and E-Stop Pushbuttons with all blenders.
There are three popular blenders: The V-Blender, the double cone, and the slant cone. Blenders rely upon the action of gravity to cause the powder to cascade within a rotating vessel. The V-Blender (also known as a twin shell blender) is one of the most commonly used tumbling blenders. The blending performance of this type of blender has shadowed many of the members of the blender family. They offer both short blending times and efficient blending.
The V-Blender is made of two hollow cylindrical shells joined at an angle of 75° to 90°. The blender container is mounted on trunnions to allow it to tumble. As the V-blender tumbles, the material continuously splits and recombines, with the mixing occurring as the material free-falls randomly inside the vessel. The repetitive converging and diverging motion of material combined with increased frictional contact between the material and the vessel’s long, straight sides result in gentle yet homogenous blending.
All blenders include the following standard features:
Intensifier bars for deagglomeration
Type 316 stainless steel parts
150 grit exterior finish, mirror finish on internal surfaces
Stainless steel support stands
Manually operated butterfly discharge valves
Fully integrated motors and controls
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 simple.
The shape of the 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.
