V-CONE
BLENDER
A low-shear twin-shell batch blender for uniform dry mixing of free-flowing powders and granules. As the sealed V-shaped vessel turns around its horizontal trunnion axis, the product repeatedly separates into both limbs, cascades and recombines at the junction.
HOW THE BLENDER WORKS
CHARGE
Load ingredients through one or both sanitary limb ports.
SEAL
Close the vessel and prove guards and interlocks.
ROTATE
The V-shell turns about the horizontal trunnion axis.
SPLIT
Twin limbs divide, cascade and recombine the bed.
VERIFY
Confirm the blend endpoint by time or sampling
DISCHARGE
Index the outlet downward and empty by gravity.
APPLICATION FIT & PROCESS VALUE
RIGHT APPLICATION
Free-flowing dry blends
Best suited to powders and granules with reasonably compatible flow and density.
Granule lubrication
Gentle diffusion can distribute lubricants while limiting granule breakdown.
Fast changeover
Smooth twin shells, two access ports and a simple interior support inspection and cleaning.
DESIGN VALUE
Diffusive mixing
Repeated split-and-recombine cycles create new particle interfaces with low shear.
Optional intensifier
A removable intensifier bar may support minor ingredients or soft agglomerates after trials.
Know the limits
Sticky, cohesive or strongly segregating formulations may require another mixer technology.
CONSTRUCTION & CONFIGURATION OPTIONS
PRODUCT CONTАСТ
SS304 or SS316L with application-specific internal
finish and weld treatment
VESSEL
Twin cylindrical shells joined in a V geometry and supported on horizontal trunnions
DISCHARGE
Flush sanitary butterfly or slide valve selected for product flow behaviour
DRIVE
Geared motor, VFD speed control, position sensing and controlled indexing
CLEANING
Two sanitary access covers, smooth internals and dry or validated wet cleaning access
SAFETY
Drive guard, zero-speed proof, position lock and interlocked perimeter protection
DIFFUSIVE TUMBLING MIXING CONCЕРТ
The V-shell rotates about the left-to-right horizontal trunnion axis, moving toward and away from the viewer in front elevation. Gravity continually establishes a new free surface while the twin limbs split, cascade and recombine the product bed.
CONTROLLED BATCH SEQUENCE
CHARGE
Confirm valve closed and add ingredients.
SEAL
Close manway and prove all safety interlocks
ROTATE
Tum about the trunnion axis at validated speed.
VERIFY
Sample or confirm the established endpoint.
INDEX
Stop at the validated discharge position.
DISCHARGE
Index outlet downward and empty by gravity.
CONTROL, SAFETY & MAINTENANCE
Start permissive
Rotation starts only with manway and outlet closed and all guards proven.
Dynamic protection
Current, vibration and bearing monitoring detect abnormal rotating load.
Position control
Proximity sensing indexes the vessel for charging, sampling and discharge.
Safe access
Zero-speed proof, isolation and mechanical position lock are required before access.
Recipe control
Rotation speed, direction, blend time and stop position are stored by formulation.
Cleaning access
Twin access covers and smooth crevice-controlled internals support validated cleaning.
STANDARD RANGE & PRELIMINARY SIZING
Screening guide for conventional free-flowing dry powders and granules. Working volume is shown at 60% of gross vessel volume; final fill level, V-angle, speed, dynamic load, power and discharge must be validated for the actual formulation.

PRELIMINARY SIZING BASIS
BATCH MASS
Mass = working volume x bulk density
Example: 1,000 L x 0.5 kg/L = 500 kg
Use loose bulk density at charging condition
CYCLE CAPACITY
Batches/h = 60/total cycle minutes
Include charge + blend + verify + discharge
Do not size from mixing time alone
WHAT CONTROLS THE FINAL SELECTION
Bulk behaviour
Density range, flowability, cohesion, angle of repose and tendency to aerate.
Blend objective
Ingredient ratio, required CV, sampling method and segregation sensitivity.
Mechanical duty
Gross batch mass, V-shell imbalance, start torque, bearings and dynamic support load.
Product protection
Fragility, abrasion, temperature sensitivity and permitted tumbling intensity.
Process limits
Cohesive, sticky or strongly segregating blends may need an intensifier, trials or another mixer.
Hygienic duty
MOC, surface finish, closures, gaskets, cleaning method and validation standard.
FINAL ENGINEERING CHECK
Confirm formulation data
Define test and CV target
Complete representative trial
Verify motor torque and seal
Agree FAT acceptance criteria
