CONTA
BLENDER
A closed-bin tumble blender for dry powders and granules. The mobile IBC serves as the charging, blending, storage and transfer container, reducing product handling and supporting fast changeover between batches
HOW THE CONTA BLENDER WORKS
LOAD
Position the filled mobile bin at the lifting station.
CLAMP
Engage the positive cradle and prove the clamp interlock
LIFT
bin to the Raise the sealed controlled blending position.
ROTATE
Tumble the complete bin about its horizontal axis.
RETURN
Index the bin upright and lower it to floor level.
RELEASE
Unclamp for transfer, storage or controlled discharge.
APPLICATION FIT & PROCESS VALUE
RIGHT APPLICATION
Pharmaceutical solids
Closed transfer and interchangeable bins support granules, premixes and tablet blends.
Food and nutraceutical powders
Gentle tumbling suits free-flowing ingredients where low product damage is important.
Specialty chemical blends
Dedicated or campaign bins can limit cross-contact and simplify material movement.
DESIGN VALUE
One container, fewer transfers
The same IBC can charge, blend, store and feed downstream equipment.
Fast product changeover
Exchange the product bin while the stationary blender remains available for the next batch.
Gentle diffusive mixing
Repeated reorientation cascades and recombines the bed without an internal agitator.
CONSTRUCTION & CONFIGURATION OPTIONS
PRODUCT CONTACТ
SS304 or SS316L bin with application-specific internal finish and weld treatment
MOBILE BIN
Square or engineered IBC with sealed lid, conical outlet, casters and positive handling points
LIFT AND CLAMP
Chain or screw lifting mast with position sensing and mechanically positive cradle clamps
ROTATION DRIVE
Geared drive with VFD, controlled acceleration. indexing and dynamic load protection
DISCHARGE
Sanitary butterfly or special outlet valve matched to flow, containment and downstream interface
SAFETY AND CONTROL
Guarding or scanner, clamp proof, position interlocks, zero-speed proof and recipe control
CLOSED-BIN TUMBLE BLENDING CONCEPT
After positive clamping and lifting, the complete sealed IBC rotates about a horizontal trunnion axis. Gravity continuously createsa new free surface, causing the powder bed to divide, cascade and recombine without an internal agitator.
CONTROLLED BATCH SEQUENCE
LOAD
Position the filled mobile bin at the station.
CLAMP
Engage the cradle and prove positive locking.
LIFT
Raise to the validated blending position.
BLEND
Rotate at the approved speed and time
HOME
Index upright and lower under control.
RELEASE
Unclamp for transfer or discharge.
CONTROL, SAFETY & MAINTENANCE
Clamp permissive
Rotation is enabled only after both clamp and bin-presence signals are proven.
Lift position proof
Upper and home positions are monitored; motion stops on disagreement or obstruction.
Dynamic protection
Drive current, torque and speed monitoring protect against abnormal rotating load.
Personnel protection
Interlocked guarding, scanner or light barrier prevents access to the rotation envelope.
Recipe control
Speed, direction, blend time, acceleration and home position can be stored by formulation.
Cleaning strategy
Product-contact cleaning is focused on the removable bin, lid, gasket and outlet valve.
STANDARD RANGE & PRELIMINARY SIZING
Screening guide for conventional free-flowing dry powders and granules. Working volume is shown at 40-70% of gross bin volume; final fill, speed, rotating mass, centre of gravity, lift, clamp and drive require application-specific verification.

PRELIMINARY SIZING BASIS
WORKING VOLUME
Vwork = Vgross x fill fraction
Example: 1,000 L x 60% = 900 L
Maintain free space for bed movement
BATCH MASS
Mass = Vwork x bulk density
Example: 600 L x 0.5 kg/L = 300 kg
Use charging-condition loose density
ROTATING LOAD
Load = bin tare + product + adapter
Verify eccentricity and centre of gravity
Drive is selected from dynamic duty
WHAT CONTROLS THE FINAL SELECTION
Powder behaviour
Density range, flowability, cohesion, aeration, segregation and angle of repose.
Bin geometry
Gross volume, internal shape, tare mass, full mass, centre of gravity and lifting points.
Blend objective
Ingredient ratio, required CV, sampling method, blend time and permitted speed.
Mechanical duty
Dynamic imbalance, acceleration, braking, trunnion load, clamp force and mast stability.
Site envelope
Available height, rotation clearance, floor load, guarding and material-flow interfaces.
Hygienic duty
MOC, finish, lid, gasket, outlet valve, cleaning method and containment requirement.
FINAL ENGINEERING CHECK
Confirm bin drawing and mass
Define CV and sampling
Complete representative trial
Verify lift and rotating load
Agree FAT acceptance criteria
