§ Hardheim, Germany
§ 01 Product / intensive mixers

Intensive mixers. From zero point one to twelve thousand liter.

Batch and continuous intensive mixers built on a single patented principle. A rotating pan. An eccentrically mounted tool. Two independent drives. One recipe, validated on the bench, running in a production hall.

§ 02 Three scales / one principle

Three platforms. Same pan and tool geometry. Same recipe, three orders of magnitude.

A recipe qualified on a laboratory unit translates cleanly to small scale pilot and to large scale production, because the mechanics of energy input and shear are engineered into the geometry.

§ A 0.1 to 5 liter

Laboratory

Recipe development and process qualification on the bench. Used to validate a binder, a solvent, a new filler or a reclaimed feed before any production material is consumed.

Bench installationGlove box readyData logging
§ B 40 to 150 liter

Small scale

Pilot production, short runs, toll work and sample campaigns. A process engineer can run a recipe in the morning and qualify a change in the afternoon without pulling a production line.

Pilot lineShort batchQuick change
§ C 500 to 12,000 liter

Large scale

Primary production machines for heavy industry. Standard, hinged, tilting and MixSolver variants available, matched to discharge geometry and cleaning regime.

§ 03 Process modes

Seven process modes.
One machine envelope.

The same intensive mixer body runs as a blender, a granulator, a kneader, a disperser, a coater, a dryer or a vacuum reactor. The mode is set by the tool choice, the drive programme and the pan jacket, not by switching to a different machine.

Mode 01
Mixing
Dry, wet or paste, from coarse blends to high viscosity masses.
Mode 02
Granulating
Build controlled granule distributions in a single pass.
Mode 03
Kneading
High shear kneading for carbon paste, battery slurries and refractory masses.
Mode 04
Dispersing
Break down agglomerates and wet fine powders into a binder matrix.
Mode 05
Coating
Surface coat fillers, additives and reactive particles.
Mode 06
Drying
Evaporative drying during the mixing cycle, with or without vacuum.
Mode 07
Vacuum operation
Degas, dry or protect reactive chemistry under controlled pressure.
§ 04 / APPLICATIONS

Where the intensive mixer earns its keep.

A short selection. The machine runs across fifteen industries. Ask a process engineer for an application note closer to your own feed.

§ 01

Li-Ion battery cathode

Qualify a slurry on a 1 liter unit, run the same recipe on a 1,500 liter production machine without re-tuning shear.

§ 02

Foundry sand

High throughput bentonite bonded sand preparation with inline moisture and molding material control.

§ 03

Refractory

Castables, vibration mixes and shaped brick masses with precise energy input per batch.

§ 04

Carbon paste

Hot paste mixing for aluminium anode production. Tilting discharge, heated pan and vacuum option.

§ 05

Concrete

High performance and self consolidating concrete recipes with short mixing cycles.

§ 06

Dry mortar

Continuous or batch mixing of cement, lime, filler and polymer modifier blends.

§ 05 Specification envelope

§ 06 Common questions

The four questions a process engineer asks first.

Short answers below. The long answer is a conversation with a senior process engineer at Hardheim.

01 How small can I start and still learn something useful? +
A 0.1 liter laboratory unit is enough to characterise the energy input and the shear profile of a new recipe. Because the pan and tool principle is geometrically consistent, what you measure on the bench holds up at production scale. Most customers begin with a laboratory or small scale unit under a process engineer supervision, then specify the production machine once the target is locked.
02 Batch or continuous? +
Both. The intensive mixer platform includes batch machines from 0.1 to 12,000 liter and continuous units for high throughput lines. Batch is preferred where recipe flexibility and traceability matter. Continuous is preferred where one recipe runs for long campaigns and discharge rate is critical.
03 Do you offer vacuum, heating and cooling on the same machine? +
Yes. The pan and the tool can be jacketed for heating or cooling, and the vessel can be sealed for vacuum operation. These options are specified per application during the expert review stage and assembled at the Hardheim works.
04 How long does a production machine take to deliver and commission? +
Lead times vary with size, variant and options. The Hardheim team gives an indicative schedule during the expert review and locks it at order. Commissioning is performed by Eirich process engineers on site, with a handover to the plant operations team and a remote Teleservice connection established as part of the commissioning package.
