PLOUGH SHEAR
MIXER
An intensive horizontal batch mixer for powders, granules and fibres. Wall-close plough tools create rapid three-dimensional circulation and a mechanically generated fluid bed. Tool geometry and controlled shaft speed support fast, repeatable blending.
HOW THE MIXER WORKS
CHARGE
Load major and minor ingredients through the top inlet.
CLOSE
Close the cover and prove guards and safety interlocks.
MIX
Plough tools lift and project the complete product bed.
FLUIDIZE
Particles exchange through radial, axial and circumferential paths.
VERIFY
Confirm the validated endpoint by time or sampling.
DISCHARGE
Open the central bottom outlet for rapid emptying
APPLICATION FIT & PROCESS VALUE
RIGHT APPLICATION
Dry bulk materials
Suitable for powdery, granular and fibrous materials, including productswith poor flow behaviour.
Minor ingredient addition
Intensive convective exchange supports distribution of small components after validated dosing.
Controlled liquid addition
Optional spray nozzles support uniform wetting or coating after representative trials.
DESIGN VALUE
Mechanically fluidized zone
Wall-close plough geometry lifts the bed and keeps the complete batch in active circulation.
Intensive plough action
Application-specific tool geometry and speed create fast
three-dimensional product exchange.
Multi-process flexibility
Mixing, moistening, coating and controlled granulation can be combined after trials.
CONSTRUCTION & CONFIGURATION OPTIONS
PRODUCT CONTACТ
SS304 or SS316L with application-specific internal finish and weld treatment
MIXER BODY
Horizontal cylindrical drum with one central shaft and application-specific plough tools
DISCHARGE
Central flush bottom valve selected for flow.
containment and cleanability
DRIVE
Heavy-duty geared main drive with VFD, torque monitoring and protected coupling
CLEANING
Hinged access cover, removable internals where required, and dry or validated wet cleaning
SAFETY
Interlocked cover, guarded main drive, zero-speed proofand lockout provisions
MECHANICALLY FLUIDIZED MIXING CONCЕРТ
Plough tools rotate close to the wall of a horizontal cylindrical drum. Their shape and arrangement lift product from the bed and generate simultaneous circumferential, radial and axial movement, keeping the complete batch in active circulation.
CONTROLLED BATCH SEQUENCE
CHARGE
Confirm outlet closed and add ingredients.
CLOSE
Close cover and prove all safety interlocks.
LIFT
Run the plough shaft at validated speed and time.
FLUIDIZE
Maintain three-dimensional circulation through the batch.
VERIFY
Sample or confirm the established endpoint.
DISCHARGE
Open the central bottom outlet and empty rapidly.
CONTROL, SAFETY & MAINTENANCE
Start permissive
Mixer starts only with cover and outlet closed and all guards proven.
Drive protection
Current, torque, speed and bearing monitoring detect abnormal load or obstruction.
Speed control
VFD control maintains the validated plough speed, acceleration and mixing duration.
Safe access
Zero-speed proof and electrical isolation are required before opening the mixer.
Recipe control
Plough speed, optional spray dose, blend time and discharge logic are stored.
Cleaning access
Wide hinged cover, smooth internals and flush outlet support validated cleaning.
STANDARD RANGE & PRELIMINARY SIZING
Screening guide for powdery, granular and fibrous products. Working volume is shown as a planning range. final fill level, plough geometry, tip speed,
torque, liquid addition 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, starting torque, shaft
deflection, bearings and transmission load.
Product protection
Fragility, abrasion, temperature sensitivity and
permitted plough tip speed.
Liquid addition
Dose, viscosity, droplet size, spray location
and allowable agglomeration target.
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 plough and drive duty
Agree FAT acceptance criteria
