Mixing principle
Fluidized, High-Intensity Batch Mixing
Rotating plough-shaped blades throw material into the free mixing space above the trough. Optional high-speed choppers break agglomerates and help disperse liquids, making this platform suitable for cohesive or fatty powders that need more energy than a ribbon mixer.
300–15k LLDH total volume range
5.5–90 kWMain motor range
50–130 RPMListed mixing speed range
SS304 / 316LContact material options
Plough action
Plough blades lift and project material through the mixing zone.
Optional choppers
High-speed choppers can break lumps and disperse liquid additions.
Intensive circulation
Particles collide, fold and redistribute in the fluidized bed.
Bottom outlet
Pneumatic discharge can be configured for fast batch emptying.

Frequently asked questions
Plough Shear Mixer Questions
When should I choose a plough shear mixer?
It is suited to cohesive powders, wet granulation, liquid addition and processes requiring deagglomeration. Free-flowing dry powders may be better suited to a ribbon mixer.
Can choppers be added?
Yes. Optional high-speed side choppers break agglomerates and support liquid dispersion during mixing.
What models are available?
The listed LDH series runs from LDH-0.3 to LDH-15, with additional LDH-0.1, 1.5, 3, 8 and 12 models available.
Can the mixer be temperature controlled?
Heating or cooling jacket options can be discussed for temperature-sensitive or reactive material processes.
What material grades are available?
SS304 and SS316L contact-part configurations are available according to the application requirement.
How do I select a model?

Plough Shear Mixer Engineering Details
Explore the plough tooling, chopper options, liquid addition features and selection data for high-intensity mixing of cohesive powders and wet granulation batches.
Introduction
The plow separates and lifts the product into three-dimensional motion, while the number and arrangement of the tools insure agitation back and forth along the length of the vessel.
When the material flows past the high-speed choppers, it is cut and scattered by the blades, achieving uniform mixing in short time. The choppers help to remove lumps in the raw material, chop pasty additives, and prevent formation of agglomerates on liquid addition.

Details
Drive unit
Standard mixers are driven directly by a gearbox, which provides high torque, reliability, and low noise. Large-scale mixing equipment, on the other hand, utilizes a combination of a gearbox and belt drive to protect the transmission components in case of unexpected situations.
Mixing unit
The unique curved blade profile effectively lifts and disperses materials while generating powerful shearing force.
Spray system
An atomizing nozzle can be added above the choppers to achieve liquid addition and mixing. Due to the lower density of the material at this position under the shearing action of the choppers, the atomized liquid is more easily incorporated into the intermixing with the powder.
Main shaft seal
When mixing ultrafine powders, the use of a new type of balanced seal and packing seal enhances the airtightness and effectively prevent the flow of gas and powder between the inside and outside of the vessel.
