VERTICAL CONICAL
RIBBON BLENDER
A top-driven batch mixer for gentle, repeatable blending of powders and granules. The conical vessel, outer ribbon and inner return helix generate three-dimensional convective circulation with low product retention and complete gravity-assisted discharge.
HOW THE BLENDER WORKS
CHARGE
Load major and minor ingredients through the top ports.
LIFT
Outer ribbon raises material along the conical wall.
RETURN
Inner helix and gravity move material down the centre.
EXCHANGE
Radial circulation distributes components throughout.
VERIFY
Mixing endpoint is confirmed by time or sample result.
DISCHARGE
Flush bottom valve supports low-residue emptying.
APPLICATION FIT & PROCESS VALUE
RIGHT APPLICATION
Powder and granule blends
Suitable for dry ingredients with different particle size, shape and bulk density.
Fragile materials
Low-speed convective mixing helps limit attrition, heating and particle damage.
Multi-product duty
Conical discharge and top-supported agitator support cleaning and recipe changeover.
DESIGN VALUE
Minor ingredient distribution
Three-dimensional circulation can disperse low-dose additives when charging is controlled.
Liquid addition
Optional spray nozzles distribute controlled liquid additions onto a moving
powder bed.
Integrated processing
Jacket, vacuum, load cells, sampler and chopper can be engineered when required.
CONSTRUCTION & CONFIGURATION OPTIONS
PRODUCT CONTACТ
SS304 or SS316L with application-specific internal finish and weld treatment
AGITATOR
Outer conical ribbon with inner return helix, top-driven on one central shaft
DISCHARGE
Flush butterfly, slide or ball-segment valve selected for powder behaviour
PROCESS
Liquid spray, high-speed chopper, heating/cooling jacket or vacuum execution
CLEANING
Wide manway, removable spray devices, CIP/SIP preparation and purged seal options
CONTROLS
VFD, torque/current monitoring, recipe control, load cells and safety interlocks
THREE-DIMENSIONAL MIXING CONCЕРТ
The outer conical ribbon lifts material along the wall while the inner return helix and gravity move it downward through the centre. Simultaneous radial exchange creates a repeating convective circulation pattern throughout the batch.
CONTROLLED BATCH SEQUENCE
CHARGE
Confirm valve closed and add ingredients.
START
Run mixer at the validated recipe speed.
BLEND
Maintain convective circulation for set time.
SPRAY
Add liquid only at the validated stage
VERIFY
Sample or confirm the established endpoint.
DISCHARGE
Open outlet while ribbon assists emptying.
CONTROL, SAFETY & MAINTENANCE
Start permissive
Drive starts only with manway closed, outlet shut and all guards proven.
Torque protection
Current or torque monitoring detects overload, compaction or foreign objects.
Seal protection
Top seal can use air purge or monitored barrier arrangement for dusty service.
Safe access
Zero-speed confirmation and isolation are required before opening the vessel.
Recipe control
Speed, charge order, spray timing and blend time are stored by formulation.
Cleaning access
Top manway, flush outlet and optional spray devices support validated cleaning.
STANDARD RANGE & PRELIMINARY SIZING
Screening guide for conventional dry powder and granule blending. Working volume is the nominal usable batch volume; final fill level, torque, power, ribbon clearance 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, aeration and tendency to compact.
Blend objective
Ingredient ratio, required CV, sampling method and segregation sensitivity.
Mechanical duty
Batch mass, friction, ribbon loading, start-under-load and foreign-object risk.
Product protection
Fragility, abrasion, temperature sensitivity and permitted shear input.
Process options
Liquid addition, chopper, jacket, vacuum, inerting and load-cell requirements.
Hygienic duty
MOC, surface finish, seals, cleaning method, access and validation standard.
FINAL ENGINEERING CHECK

Define test and CV target
